Free Threads tools
Four free tools for people who write on Threads: count characters and split long text into a thread, find communities to join, calculate engagement rate, and style text with Unicode fonts. No sign-up, and nothing you type leaves your browser.
What's here
Each tool does one job and works without an account. The text you paste stays on your device: the pages don't send it to our server or anywhere else.
- Character counter. Checks a post against the 500-character limit, counts emoji the way Meta's API does, flags more than five links, and splits a long text into numbered thread parts with a preview.
- Communities list. 64 Threads communities with member counts, searchable by topic, so you can see where people in your field already talk.
- Engagement rate calculator. Turns likes, replies, reposts and quotes into a rate by views and by followers.
- Font generator. Bold, italic, script and 13 other Unicode styles you can paste into a post or bio, with the character and byte count of each.
If you use Threads to find clients, the guides explain the rest: how to get clients on Threads and how to go viral on Threads.
