# ChatGPT Connectors: Post to Social Media, Developer Mode **Source:** https://posteverywhere.ai/connectors/chatgpt --- Works as a ChatGPT custom connector # Turn on Developer mode, then let ChatGPT publish for you Yes, but only after you turn on Developer mode. Custom connectors stay hidden until you do, so there is nothing to click without it. ChatGPT can publish your social posts once you add PostEverywhere as a custom connector. The connector gives it real tools, so it schedules through the platforms’ official APIs rather than pretending to click around a browser. One thing is worth saying before you start, because it is the single most common reason this fails: custom connectors do not appear in ChatGPT until Developer mode is switched on. It is web only, it needs a paid ChatGPT plan, and it is not in the phone apps. If you cannot find where to add a connector, you have not missed a menu, the option is genuinely hidden. After the connector is approved it stays available in new chats, so the Developer mode hunt is a one-time cost. From then on, anything already in the conversation, a pasted draft, an uploaded file, a Canvas document, can become a scheduled post without leaving the thread.

Once Developer mode is on, the rest takes about a minute. Before you start - A paid ChatGPT plan: Plus, Pro, Business, Enterprise or Education. Developer mode is not available on free. - A desktop browser. Custom connectors are not exposed in the ChatGPT mobile apps at all. - A PostEverywhere plan and at least one connected social account, or the connector authorises and then has nothing to publish to. Turn on Developer mode first, or there is nothing to click Custom connectors are hidden until you enable them: Settings, then Apps, then Advanced settings, then Developer mode. This is web only, and needs Plus, Pro, Business, Enterprise or Education. It is not in the phone apps. - 1In ChatGPT settings, turn on Developer mode.

See [the ChatGPT connector setup in the API docs](https://posteverywhere.ai/docs/integrations/mcp#connect-from-chatgpt). ## What you can ask ChatGPT once it is connected ChatGPT is strongest here when the source material is already in the thread: a Canvas draft, an uploaded file, a half-written idea. Each one maps onto a real tool, covering scheduling, [AI captions](https://posteverywhere.ai/ai-content-generator) and [analytics](https://posteverywhere.ai/social-media-analytics). The [AI agents page](https://posteverywhere.ai/agents) has the full surface. Turn a Canvas draft into scheduled posts without copying between tabs Take a file you uploaded and publish the summary to LinkedIn Send one announcement to every connected account in a single message Ask what published yesterday and how each post performed Retry anything that failed overnight, and find out why it failed Draft next week, revise it in the thread, then schedule the approved version ChatGPT can draft, schedule, reschedule and report on posts across all the top platforms. The connector is scoped to your PostEverywhere account, so it can only reach the social accounts you have already authorised. ### What the tools cover The connector exposes 38 tools, covering scheduling, media upload, campaign grouping, analytics and account health. In practice most ChatGPT sessions use three of them: draft, schedule, and read back performance. The rest matter when something goes wrong, which is when being able to ask why a post failed, in the same thread where you wrote it, saves opening the dashboard at all. ### Prompts that work, and what comes back “Use the brief I uploaded to draft five posts, then schedule them across next week.” ChatGPT reads the file already in the thread, drafts from it, and queues each post without you copying anything out. “Turn this Canvas draft into a LinkedIn post and schedule it for tomorrow morning.” It converts the draft in place and puts it in the queue, so the Canvas stays your working copy. “Which of last week's posts got the most engagement?” It reads the analytics back into the conversation, so you can ask for another version of the winner in the same breath. ## ChatGPT connector and Developer mode troubleshooting The three things that actually go wrong, and what fixes each one. Advanced settings has no Developer mode entry You are on the free plan. Developer mode requires Plus, Pro, Business, Enterprise or Education, and there is no way to enable it otherwise. The connector was created but exposes no tools Authentication was probably left on None. Custom connectors need OAuth selected before you press Create, otherwise ChatGPT has no way to identify your account. It works on desktop but not on my phone That is expected. Custom connectors are a web feature and the mobile apps do not surface them at all. ## What it will not do Worth knowing now rather than after you have started a trial. - It will not appear on your phone. The connector is a web feature and the mobile apps do not surface it. - It does not publish on its own. ChatGPT schedules when you ask it to, and the post is visible in your calendar before it goes out. - It cannot manage comments or messages. Publishing and reading performance only. ## When to use ChatGPT rather than another assistant ChatGPT suits people whose source material is already in the chat. If you are working from an uploaded brief or a Canvas draft, the shortest path from that text to a scheduled post runs through here. Reference material: [OpenAI on MCP](https://platform.openai.com/docs/mcp), [The Model Context Protocol spec](https://modelcontextprotocol.io). The full agent surface, including the REST API, is on the [AI agents page](https://posteverywhere.ai/agents). ## Included on every paid plan from $9/mo You need a paid ChatGPT plan for Developer mode, which is OpenAI's requirement rather than ours. On our side it is on every plan from $9. One key covers the connector, the [REST API](https://posteverywhere.ai/social-media-api) and the SDK. Using a different assistant? [See all connectors](https://posteverywhere.ai/connectors), wire it up from [n8n, Make or Zapier](https://posteverywhere.ai/integrations), or read how the whole [agent setup](https://posteverywhere.ai/agents) fits together.
