About

Draft a post once and format it for every platform at the same time. The main editor uses TipTap for word-processor-style editing, and a live preview rail shows your post on LinkedIn, X, Bluesky, Threads, Mastodon, Facebook, and Instagram, each with its own character limit, counting rule, and formatting applied. - Web app — the multi-platform editor. Live at https://aka.ms/Polypost - LinkedIn browser extension — a LinkedIn-only companion that turns LinkedIn's own composer into the editor: Start a post opens it in place of the native box, and Post publishes through LinkedIn's own flow. See LinkedIn browser extension. This is not an official app of any platform. Drafts stay in your browser; the extension only acts on LinkedIn when you click Post. Polypost is the open-source project markrussinovich/Polypost (https://github.com/markrussinovich/Polypost) by markrussinovich, released under MIT. Ion packages it unmodified from commit cae3f732c970, adding only a manifest, an icon and a storage compatibility script.
