PostWire in ChatGPT: write and schedule social posts from the chat

The same connector that runs in Claude: one idea in, a native post for each network out, published or scheduled after you approve — TikTok, Instagram, Facebook Pages, YouTube, LinkedIn, Bluesky, Mastodon, Telegram and Discord.

Status on September 26, 2026: PostWire is not in ChatGPT's app directory yet; the submission is being prepared. If your ChatGPT plan lets you add a custom connector (developer mode), you can use it today with the URL below and sign in with OAuth. Menu names in ChatGPT change often, so follow OpenAI's current help page for where that setting lives.

How it works once connected

  1. Sign in with your emailA 6-digit code creates your free PostWire account inside the sign-in window. No card.
  2. Connect a networkAsk for a link to connect Bluesky, LinkedIn, Telegram, TikTok or another network; it opens in your browser for one hour.
  3. Ask for a post or a week of postsYou see every draft first. Nothing is published until you approve it.

Limits and upgrades work as in Claude: when a limit is reached the answer names the plan that lifts it, its price and a checkout link; nothing is charged from the chat, and paid plans have a 14-day refund. Full guide and troubleshooting · agent.md
