ChatGPT Apps and Connectors: A Complete Guide

ChatGPT can work with approved external tools, files and organizational knowledge through connected capabilities. OpenAI now groups these under the term Apps in ChatGPT — a unified framework for file search, synced knowledge, deep research, custom integrations and more. Many users and organizations still call them connectors.

Terminology note: OpenAI now calls connectors “Apps in ChatGPT”. This guide uses both names, because many users and older resources still say ChatGPT connectors. Everything described depends on your organisation’s plan, workspace setup and admin settings.

Quick Answer

ChatGPT connectors, now called Apps in ChatGPT, let ChatGPT work with approved outside services, files and company information. Depending on the app, plan and workspace settings, they may support file search, synced knowledge, deep research, interactive features or controlled actions, while respecting the permissions and admin controls in place.

What Are ChatGPT Connectors?

By default, ChatGPT works with what it learned in training and what you give it in a conversation. ChatGPT connectors, now officially called Apps in ChatGPT, let ChatGPT reach approved outside services, files and company knowledge when they are relevant to your request.

The move from “connectors” to “Apps” reflects OpenAI’s aim of one consistent way to use connected features. Whether you are searching internal documents, using synced team knowledge or using a custom connection, it is all managed through Apps in ChatGPT.

A key principle is that connecting an app does not grant unrestricted access to all information in the connected system. Personal connections use the connected user’s source permissions; shared or agent-owned connections can have a different access scope. Administrator controls determine which apps are enabled, for which user groups, and with what scope.

Important: What connected content you can reach depends on your permissions in the connected system, your workspace admin’s setup, your organisation’s ChatGPT plan and what is currently available. Features and apps vary by plan, region and workspace settings.

Terminology Mapping: Connectors to Apps

OpenAI has unified connected capabilities under the Apps in ChatGPT framework. The table below maps commonly used older terms to the current terminology, based on publicly documented product information. Not all features may be available on all plans or in all regions.

These terms come from OpenAI’s public product information. Feature names and availability may change as the product develops. Check the current terms in your workspace documentation.

How ChatGPT Apps Work: A Conceptual Overview

When a connected app is enabled and relevant to your request, ChatGPT can retrieve permitted content from the connected source as part of generating its response. The conceptual flow looks like this:

Key points about this workflow:

• ✓ Not every request triggers a connected app — ChatGPT determines whether connected context is relevant.
• ✓ Access follows the connected account and approved scopes. Test personal and shared connections separately.
• ✓ Source citations or references are provided where the specific app supports them.
• ✓ Users retain responsibility for reviewing and verifying all responses.
• ✓ Action confirmation depends on app and workspace permissions. Configure review for consequential changes; do not assume every write automatically shows a confirmation prompt.
• ✓ Behavior varies significantly between different apps and feature configurations.

Types of Apps in ChatGPT

OpenAI lists several types of connected app feature. Which ones you can use depends on your plan, region, workspace setup and admin settings.

Apps with File Search

• • Search and reference content within connected document collections, SharePoint libraries or approved file sources.
• • Suitable for document lookup, policy retrieval, reference-checking and knowledge queries.
• • Responses cite connected sources where supported — users should verify citations directly.
• • Access depends on the connection identity, scopes and source permissions. Review shared connections separately from personal ones.
• • Administrator controls which file sources are connected and which users can access them.

Apps with Sync

• • Content from connected sources is indexed or synchronized so it can be referenced across conversations.
• • Reduces the need to re-upload or re-link documents for recurring knowledge workflows.
• • Sync is not instantaneous — there may be a delay between content updates and availability in ChatGPT.
• • Freshness and completeness depend on sync schedule, source system availability and configuration.
• • Organizations should communicate expected sync lag to employees and account for it in critical workflows.

Apps with Deep Research

• • Research workflows that draw on connected sources alongside broader research capabilities.
• • Useful for analysis, synthesis and research tasks that benefit from connected organizational context.
• • Sources used in deep research should be reviewed — human judgment is essential for interpreting findings.
• • Not appropriate as a replacement for verified primary research or compliance-grade analysis.
• • Feature availability and connected source behavior vary by plan and workspace.

Interactive Apps

• • Some apps may provide richer, more structured user interface experiences within ChatGPT.
• • Interactive capabilities depend on the specific app — not all apps offer enhanced interaction.
• • How each app is made available and how you use it are set by the app’s developer and by OpenAI’s policies.
• • Employee training should cover how interactive apps differ from standard ChatGPT conversations.

Custom Apps and MCP-Powered Apps

• • Organizations with appropriate plan access and development resources may build custom integrations.
• • Some custom apps use MCP (Model Context Protocol) as the underlying connection mechanism — see the MCP guide for details.
• • Custom apps require development, security review, administrator deployment and ongoing maintenance.
• • Access and action scope must be carefully designed following least-privilege principles.
• • Not every workspace or plan supports custom app development — check current plan documentation.
• • Custom apps that touch sensitive systems require rigorous testing and security assessment before deployment.

Apps vs Company Knowledge: What Is the Difference?

Two terms that are often confused in enterprise ChatGPT discussions: Apps and Company Knowledge. They are related but not interchangeable.

📦 Apps in ChatGPT

• • Individual connected integrations — each app connects ChatGPT to a specific external service or file collection
• • May support search, sync, deep research, interaction or actions depending on the specific app
• • Enabled and managed by administrators at the workspace level
• • Each app has its own scope, permissions and available features

🏢 Company Knowledge

• • Organizational answers sourced from connected, approved knowledge sources within the workspace
• • Designed for knowledge discovery — employees can ask questions and receive answers with citations where supported
• • Access is permission-aware — results follow the feature’s supported connection and permission model
• • May use connected apps as the underlying data source — but company knowledge is an organizational feature, not just another app

In practice: Think of Apps as the individual connections (to SharePoint, Google Drive, a CRM or your own system), and Company Knowledge as the layer that uses those connections to answer staff questions. A company knowledge question may draw on several connected apps, but using one app to search specific documents is different from a company knowledge question.

ChatGPT Apps, Connectors and MCP: What Is the Difference?

Most end users interact with Apps through the ChatGPT interface and never need to think about MCP. Developers and administrators who are building or deploying custom integrations may use MCP as the underlying technical mechanism. For a full explanation of MCP including how it works, what MCP servers and clients are, and enterprise security considerations, see the complete MCP guide.

ChatGPT Apps vs RAG: Not the Same Thing

🔌 ChatGPT Apps

A product-level framework that connects ChatGPT to external services and data sources. Apps may support search, sync, research or actions depending on their capabilities. Not all apps retrieve documents in the RAG sense — some provide structured data, actions or live service queries. Apps are a product experience layer.

📚 RAG (Retrieval-Augmented Generation)

An AI architecture pattern where relevant documents or chunks are retrieved from an index and passed to the model as context to ground its responses. RAG is a technical retrieval approach. A connected app may use RAG under the hood to retrieve document content, but RAG and apps are not the same concept.

Enterprise AI systems often combine apps, search, RAG pipelines, permission controls and company knowledge. Understanding which layer does what helps administrators design reliable, secure and well-governed deployments. For an architectural deep dive on retrieval, see what is RAG and the production RAG system architecture guide.

Apps vs Reusable Assistants and Custom Configurations

ChatGPT lets organisations set up reusable assistants (called GPTs or custom assistants, depending on plan and features), with instructions, a persona and a way of working defined once and reused across conversations.

📋 Reusable Assistants / Custom Configurations

• • Organize instructions, prompts and workflow context for repeated use
• • Define consistent personas, tone and task focus
• • May be combined with connected apps for richer functionality
• • Feature naming and availability vary by plan

🔌 Apps in ChatGPT

• • Provide connected capabilities or data access from external systems
• • Enable file search, sync, deep research, custom integrations
• • May be used alongside custom assistant configurations
• • Require admin enablement and permission configuration

Feature names, availability and the relationship between assistants and apps may change over time as OpenAI updates the product. Verify current feature naming and availability in your workspace.

Enterprise Use Cases for ChatGPT Apps

These examples show how organisations can use connected apps. Each needs the right permissions, an admin to switch it on and a person to check results before acting on them.

Every use needs the admin to switch it on, sensible permission design and staff training. Do not connect systems that hold confidential or regulated data until your organisation has reviewed and approved it.

Security, Permissions and Administrator Controls

Connected apps extend what ChatGPT can do, and they also extend what your organisation has to secure. The points below apply to any organisation judging or rolling out Apps in ChatGPT.

Third-party service involvement

Connected apps may involve third-party services with their own data handling practices, terms and privacy policies. Review these before enabling any app.

Existing permission boundaries

Check the identity behind the connection. A personal connection uses that person’s permissions; a shared or agent-owned connection uses the connected account’s permissions, which may differ. Test access boundaries before rollout.

Administrator controls

Workspace administrators can enable, disable or restrict which apps are available, to which users and with what scope. Establish clear app governance policies before deployment.

Action review

Apps that can take actions in connected systems (creating records, sending messages, updating data) require additional human review steps. Do not automate consequential actions without approval workflows.

Data flow assessment

Understand which data flows between your systems and OpenAI when an app is used. Consult your organization's data classification policy and relevant data agreements.

Sensitive data policies

Define which data classifications are permitted in ChatGPT app workflows. Not all data is appropriate for connected app use. Establish clear guidelines before deployment.

Third-party terms

Apps may be provided by third parties. Review their terms, privacy practices and security posture independently from OpenAI's terms.

Custom app security review

Apps an organisation builds itself need a security review during development, penetration testing where it fits and ongoing monitoring. The organisation that builds a custom app is responsible for its security.

Human review requirement

Connected app responses must be reviewed by humans before being acted upon, shared externally or used in decisions. Never treat app output as automatically verified or authoritative.

Compliance is not automatic

Switching on apps with company data does not make a task compliant on its own. Ask your legal, compliance and security teams about regulatory requirements. This guide is not compliance advice.

How Administrators Should Evaluate a Connected App

Before switching on any app for company use, admins should work through the questions below. This is general guidance, so ask your legal and security teams for a formal review.

Business need

What specific problem does this app solve? Is there a clear, documented use case with measurable benefit?

Data accessed

What data does the app access? From which systems? Are those systems permitted for AI integration under current policies?

Permissions required

What user and system permissions are needed? Can the app be configured with least-privilege access?

Actions available

Can the app take actions (create, update, delete, send) in connected systems? What approval workflow is required for actions?

Third-party terms

Has legal reviewed the app provider's terms of service, data processing agreement and privacy policy?

User groups

Which users or teams need access? Can access be restricted to specific groups and not enabled for all users by default?

Data sensitivity

What is the data classification of the information the app can access? Is that classification permitted in ChatGPT workflows?

Logging and visibility

Are app interactions logged? Can administrators review usage and identify unexpected behavior?

Testing plan

Has the app been tested with representative scenarios before wide deployment? Have permission boundaries been verified?

App owner

Who is the internal owner responsible for this app — for maintenance, issue escalation and periodic review?

Rollback and removal

Is there a clear process for disabling or removing the app if a problem is identified? Has this been tested?

Review frequency

How often will this app be re-evaluated? Technology, business needs and risk posture change — schedule periodic reviews.

How Employees Should Use Connected Apps Responsibly

Use only approved apps

Never attempt to connect unauthorized services or work around app restrictions. Use only apps that administrators have enabled for your workspace and role.

Verify the source

When a connected app surfaces information, check the cited source directly for important decisions. Citations help but do not replace primary source verification.

Review citations

Read cited documents or sources when they are provided. Do not rely solely on the generated summary — the source may contain important context or nuance.

Avoid unapproved sensitive data

Do not paste or refer to classified, regulated or confidential information in connected app tasks, unless your organisation has clearly approved it for that specific task.

Do not assume current information

Synced data may be delayed. The app may not reflect recent changes. Verify time-sensitive information directly in the source system.

Check permissions before sharing

Connected app results may include information that not everyone is authorized to access. Do not share results without verifying that recipients are authorized.

Review generated actions

For apps that can take actions, review every proposed action carefully before approving. Actions in connected systems may have real consequences.

Escalate uncertainty

If you are unsure whether a connected app workflow is appropriate, the response seems wrong, or an action seems risky — escalate to your manager or IT/admin team rather than proceeding.

Follow company policies

Your organization's AI acceptable-use policy, data handling guidelines and app-specific usage rules apply to all connected app workflows.

Common Limitations of ChatGPT Apps

Understanding limitations before deployment prevents unrealistic expectations and workflow design errors.

App availability varies

Not all apps are available on all plans, in all regions or for all workspace configurations.

Plan and workspace differences

Business, Enterprise and Edu plans may have different app catalogs, features and limits. Verify with your administrator.

Sync delay and stale data

Synchronized content may not reflect the most recent changes in the source system. Always verify time-critical information.

Incomplete source coverage

Connected apps only surface content they have access to. Important information may exist in systems not connected to your workspace.

Permission-limited results

A user may receive a partial or no result if they lack permission to access some or all of the relevant connected content.

Citation limitations

Not all apps provide citations for all responses. Where citations are absent, the source of information may be unclear.

Hallucinated interpretation

Even with connected context, the model may misinterpret retrieved information, combine sources incorrectly or generate errors.

Action failures

Apps that support actions may fail, return errors or produce partial results if the connected system is unavailable or the action is not permitted.

Third-party outages

A connected app depends on the availability of the external service. Service outages affect app functionality.

Administrator restrictions

Administrators can restrict apps at any time. Workflows that depend on specific apps may be disrupted if an app is disabled.

Evolving terminology and features

App names, feature availability and product terminology may change over time. What works today may be named or structured differently in a future release.

Common Mistakes Organizations Make with ChatGPT Apps

Enabling too many apps without clear use cases

Broad enablement without defined use cases creates security surface without corresponding value. Start with a small set of well-defined, high-value use cases.

Connecting sensitive systems without review

CRM, financial systems, HR records and other sensitive data sources require thorough security, legal and compliance review before connection.

Treating connected answers as automatically correct

Even with connected context, ChatGPT can generate incorrect, incomplete or outdated responses. Human review is always required.

Ignoring permission design

Deploying apps without verifying that permission boundaries work as expected for different user groups creates data access risks.

Failing to train employees

Apps rollout without training leads to inconsistent use, incorrect interpretation of results, and accidental policy violations.

No designated app owner

Every enabled app should have an internal owner responsible for monitoring, issues and periodic review — without an owner, problems are not caught.

No offboarding or revocation process

When employees leave or change roles, their app access must be reviewed and revoked where appropriate. Plan this before deployment.

No monitoring of app usage

Without visibility into how apps are being used, organizations cannot detect misuse, over-reliance or unexpected data access patterns.

Confusing Apps with unrestricted company knowledge

Connected apps do not provide access to all company data — only approved, permitted sources. Employees and managers need clear expectations.

Confusing MCP with a complete governance solution

MCP is a way of connecting systems, not a set of rules. Governance needs policies, training, access controls, monitoring and people overseeing it; MCP only helps with the technical connection.

A Staged Implementation Roadmap for Organizations

A phased approach reduces risk and increases the likelihood that connected app deployments deliver sustainable value. Organizations considering ChatGPT enterprise training can use this roadmap to align training with the deployment lifecycle.

Define the business problem

Identify a specific, measurable problem that connected app capabilities can solve. Avoid starting with "let's connect all our data."

Identify approved data sources

Decide which systems hold useful, suitable data that meets your company’s rules on which kinds of data may be used with AI.

Review security and permissions

Conduct a security assessment of the proposed connection. Verify permission behavior, data flow and third-party terms.

Select a small pilot group

Start with a limited group of informed volunteers who understand they are testing the app and will provide structured feedback.

Enable limited apps

Enable only the specific app or apps needed for the pilot use case. Avoid broad enablement during the pilot phase.

Train employees on responsible use

Before the pilot group uses the app, provide training on what it does, what it cannot do, how to verify responses and what to report.

Test real use cases

Run the pilot with actual workflows. Document what works, what fails, what produces unexpected results and what employees find confusing.

Review output quality and controls

Check answer quality, whether permissions held, which sources were covered and any security or ease-of-use problems found in the pilot.

Expand gradually

If the pilot demonstrates value and acceptable controls, expand access to additional teams with continued training and monitoring.

Monitor and reassess

Keep monitoring how apps are used, run regular security reviews and review both the app and your own policies as the technology changes.

For Technical Teams: Custom Apps and Developer Considerations

Organisations with developers and eligible ChatGPT plans may be able to build their own connections. The points below are for technical teams planning, building or judging custom app work.

Custom app development

Custom apps can extend ChatGPT to internal systems not covered by available third-party apps. Development requires API knowledge, security design and administrator deployment support.

MCP-powered integrations

Some custom app architectures use MCP (Model Context Protocol) to create standardized connections. MCP provides a common protocol for tool and data source connections — see the MCP guide.

Developer and admin mode

OpenAI provides developer documents for building and testing custom ChatGPT connections. Check the current documents for which developer tools are available and what your workspace needs.

Authentication and permissions

Custom apps must implement appropriate authentication (OAuth, API keys, service accounts) and enforce that each user only accesses data they are authorized to see in the source system.

Action safety design

Apps that perform actions must implement explicit confirmation steps, idempotent operations where possible, and clear error handling. Human approval must be built into consequential action flows.

Admin deployment

Custom apps must be deployed and enabled through workspace admin controls — not distributed informally. Deployment includes scope definition, user group assignment and monitoring configuration.

Observability and evaluation

Build logging into custom apps from the start. Log what data was accessed, by whom, in what context. Evaluate app response quality against defined criteria before wide deployment.
