AI for LinkedIn
AI for LinkedIn posts, comments and messages
Write LinkedIn posts, comments and DMs with AI in your own voice. KeyShift rewrites, shortens, fixes grammar and drafts replies in the LinkedIn text box on Windows and Mac. Free plan.
LinkedIn rewards consistent posting and quick, thoughtful replies. It punishes typos and the generic AI voice everyone can now spot.
KeyShift works in the LinkedIn text box in your browser. Write the post the way you talk, then fix the grammar, tighten it or restructure it with one shortcut. Save a custom action that carries your rules ("no hashtags, short lines, no buzzwords") so every post sounds like you.

What LinkedIn's own AI covers
LinkedIn offers AI writing help for posts and messages on Premium in some regions. It writes in LinkedIn's voice. KeyShift writes in yours, with rules you set once, and the same tool works for the newsletter draft in Docs and the follow-up email.
How KeyShift works, in any app
- Quick Actions: select text, press Ctrl+Shift+A (⌘⇧A on Mac), pick an action. The result replaces the selection.
- The typed trigger: write normally, add keyshift plus your instruction, press space twice. No selection, no shortcut.
- Voice (Ctrl+Shift+M), text from screen (Ctrl+Shift+O) and clipboard history (Ctrl+Shift+V) for the text you do not have yet.
- Undo any replacement with Ctrl+Shift+Z, up to 20 steps.
Windows 10 and later, macOS 11 and later, and Android. See the getting started guide.
Tips for LinkedIn
- Write the post first, then run the action on the whole thing. Rewriting line by line loses the thread.
- A custom action with your style rules is the single most useful thing to set up here (Pro).
- Use Shorten on comments; the best LinkedIn replies are two lines.
Questions people ask
Will my posts sound like AI?
Not if you give KeyShift your rules. Custom actions keep your phrasing, your sentence length and your bans (no "delve", no hashtags). The result is your draft, edited, not a generated post.
Does it work in the LinkedIn mobile app?
On Android, yes, with the KeyShift keyboard. iPhone is coming.
Is there a free plan?
Yes, 25 AI actions a month. Custom actions are on Pro, from €4 a month billed yearly.
