How to Post to LinkedIn from Claude, ChatGPT, and Other AI Assistants

Published 2026-03-20 by InfiniteApps

LinkedIn is the most important platform for professional content. Here's how to post to LinkedIn directly from your AI assistant — no browser, no copy-paste, no LinkedIn app.

The Short Version

  • Create a free SendIt account
  • Connect your LinkedIn account via OAuth
  • Set up your AI assistant (Claude, ChatGPT, or others)
  • Say: "Post to LinkedIn: [your content]"
  • That's it. SendIt handles the LinkedIn API, formatting, and publishing.

    Posting from Claude

    Claude uses the Model Context Protocol (MCP) to connect to SendIt. Once configured:

    "Post to LinkedIn: Excited to share that our team just shipped a major update. Here are the 3 things that made it possible..."

    Claude sends this to SendIt, which publishes it to your LinkedIn profile. The post appears immediately, just as if you'd written it in the LinkedIn app.

    Posting from ChatGPT

    Install the SendIt GPT from the GPT Store, connect your accounts, and:

    "Write a LinkedIn post about the importance of developer experience and publish it"

    ChatGPT drafts the content and SendIt publishes it. You can review before publishing or let it go directly.

    Any MCP-compatible AI assistant works with SendIt. The setup is similar: add the SendIt MCP server, configure your API key, and start posting.

    Scheduling LinkedIn Posts

    You can also schedule posts for optimal times:

    "Schedule a LinkedIn post for Monday at 9am EST: Weekly insights from our engineering team..."

    SendIt handles timezone conversion and queues the post.

    Multi-Platform from One Message

    The real power: post to LinkedIn AND other platforms simultaneously:

    "Post to LinkedIn and X: Just published a deep dive on AI-native social media. Link in comments."

    SendIt automatically adjusts character limits and formatting for each platform (3,000 chars for LinkedIn, 280 for X).

    Why Not Just Use LinkedIn Directly?

    If you're posting once a week, the LinkedIn app works fine. But if you're:

    Then an AI-native workflow saves significant time. And with SendIt's free tier (100 posts/month, all platforms), there's no cost to try it.
