LinkedIn
Reply Monk learns how you write, then drafts LinkedIn comments and posts that sound like you. You read every word and press post yourself.

Nine sites, one reply bar

A note on LinkedIn
LinkedIn restricts third-party tools. Because of that, the extension starts in LinkedIn-safe mode: it adds nothing to LinkedIn until you switch it on and read a short risk note. Even then it only drafts comments for you to review, and you post them yourself. Safe mode lowers the risk; it doesn’t remove it.
Prefer to keep it off LinkedIn entirely? Reply Studio in the web app is the no-extension alternative: paste a post, get three replies, copy and open LinkedIn.
