# 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](https://replyvero.com/guides/get-clients-on-threads/) and [how to go viral on Threads](https://replyvero.com/guides/go-viral-on-threads/).
