ChatGPT Connectors on Mobile and iPhone

Connector access in the ChatGPT mobile app on iOS and Android may not match what is available in the desktop browser version. Some connector features that appear in the web interface are not yet supported in the mobile app, and the experience for setting up or managing connectors differs between platforms. Tools like fenbs can keep the project brief and task context available across all your devices, so your AI session picks up where it left off whether you are on your phone or at your desk.

This page covers how to check connector availability on mobile, what is different from the browser experience, and how to work effectively when connector support is limited.

How to check connector availability on your plan

Connector availability in ChatGPT depends on your plan and the platform you are using. OpenAI controls which features are available on each plan and platform, and this changes as features roll out. The most reliable way to check is to open the ChatGPT mobile app, start a new conversation, and look for the connector or tools icon. If it does not appear, the feature is not available on that plan or platform at the current time.

Check OpenAI's help center↗ (opens in a new tab) for the current list of features available on each plan and platform. Do not rely on third-party articles for up-to-date plan details, as these change frequently.

What is different about connectors on mobile

Even when connector features are available on mobile, the experience can differ from the desktop browser version in a few ways.

• Setup: adding a new connector or completing an OAuth authorization may be easier on desktop, where browser pop-ups and redirects work more predictably.
• Management: editing, removing, or reviewing connector settings may only be available in the web interface.
• Feature parity: some connector capabilities, such as file access or developer mode tools, may roll out to mobile later than to the desktop browser.
• Screen size: connector-generated responses with tables, code, or long structured output are harder to read on a small screen.

If you need to set up a new connector, doing it on desktop and then using it on mobile is usually more reliable than trying to complete the OAuth flow on a phone.

Using connectors on a phone when they are available

When connectors are available on the mobile app, using them works similarly to the desktop version: start a conversation, activate the connector, and ask your question. The connector makes an outbound request to the registered endpoint and returns the data to ChatGPT.

The practical limits on mobile are context and input. Typing a long, detailed prompt on a phone is slower. Consider writing the prompt on desktop first or keeping a reusable prompt in a notes app. For using connectors on a phone in another AI tool, see claude connectors mobile as a reference for how mobile connector experiences compare.

Keeping project context across devices

Whether you start a session on your iPhone and continue on desktop, or hand off from ChatGPT to another AI tool, the context you built does not travel automatically. Each session starts fresh, and the work you did in a previous conversation is not available to a new one.

fenbs keeps that context in one place that any connected AI app can read, regardless of which device you are using. The project goal, current tasks, Decisions and rules, and Where we left off are available whenever a connected assistant reads them. For a detailed look at connector and app availability across ChatGPT, see chatgpt connectors and apps.

The cross-device gap is most noticeable when you start a task on your phone and then need to continue it on desktop, or vice versa. A conversation you had on mobile about a project decision does not appear in a new desktop conversation. If you approved a direction, agreed on a next step, or confirmed a piece of information while commuting, that conclusion is not available when you sit down at your desk. Recording those decisions in fenbs before you close the mobile conversation means the desktop session can read them immediately. The same works in reverse: a detailed plan you built on desktop is available to a quick check-in session on mobile without you needing to re-enter the context.

How to do this with fenbs

1. Create a free account. One person is free with no credit card. fenbs also has a phone app on the App Store and Google Play.
2. Add your project and write the current tasks and Decisions and rules.
3. Connect ChatGPT to fenbs from Integrations using the MCP setup guide. Complete the OAuth sign-in on desktop for a more reliable setup.
4. On mobile, ask ChatGPT to read the fenbs context at the start of each session.
5. Before stopping on any device, ask ChatGPT to save progress so the next session, on any device, starts from the right place.

fenbs has both a web app and a phone app, so you can view and update the project brief on the same device you are using for ChatGPT. For troubleshooting connector issues on any platform, see chatgpt connectors not working.
