In short
ChatGPT and Claude can work with X (Twitter) through Octapost, a social media platform that works as a remote MCP server. Once connected, your assistant drafts posts with text and up to 4 images or a video, designs editable visuals at 1280 × 720 for landscape images, 1080 × 1080 for square images and 720 × 1280 for vertical video and reads analytics such as impressions, likes, replies and reposts. It saves drafts only: you review them and publish or schedule from Octapost. Plans start at $14 a month.
What your assistant can do for X (Twitter)
Drafts made for X (Twitter)
Captions, hashtags and media are prepared in the formats X (Twitter) supports: posts with text and up to 4 images or a video.
Visuals at the right size
Designs come out at 1280 × 720 for landscape images, 1080 × 1080 for square images and 720 × 1280 for vertical video, as editable layers in the Octapost image editor, so you can still change any word or photo.
It asks before it assumes
X needs no extra settings. The assistant writes a separate caption for X within its 280 character limit when the same post also goes to other networks.
Answers from your analytics
Ask what worked last month. It reads impressions, likes, replies and reposts that Octapost has already synced, for up to 90 days.

Frequently asked questions
Can ChatGPT or Claude post to X (Twitter) directly?
Not through Octapost. Your assistant prepares the post as a draft, with media and settings, and gives you a link. You open it in Octapost and publish or schedule it yourself, so nothing goes live without a person approving it.
Does it work with Claude as well as ChatGPT?
Yes. Octapost is a remote MCP server, so ChatGPT, Claude, Cursor and other apps that support remote MCP servers with OAuth connect with the same URL: https://www.octapost.app/api/mcp.
Is Octapost in the ChatGPT or Claude app directory?
Not yet. You add it as a custom connector, which takes about a minute and needs no API key. Custom connectors may require a paid ChatGPT or Claude plan.
Which plan do I need?
Any paid Octapost plan, from $14 a month. Free trials do not include assistant access. Writing is done by your own assistant; generated images use your Octapost AI tokens.
Does it respect the X character limit?
Yes. Drafts for X get their own caption within 280 characters, even when the same post goes to Instagram or LinkedIn with a longer caption.
Is Octapost the same as Octopost or Oktopost?
No. Octapost, spelled with an a, is the social media platform at octapost.app. It is not affiliated with Octopost (octopost.ai or getoctopost.com) or Oktopost (oktopost.com).
