Free tools
Small tools that count the way each network does.
They run in your browser. Nothing you type is sent anywhere.
- LinkedIn text formatter
Select words, pick a style, copy. Free, runs in your browser, nothing is sent anywhere.
- LinkedIn post preview
Paste a draft to see roughly what shows before "…see more" and how close you are to 3,000 characters.
- X (Twitter) character counter
Links count 23, emoji and CJK count 2. A plain character count gets X wrong; this doesn't.
- Bluesky character counter
Bluesky counts what you see as one character, not code units. Bytes matter too.
Why another character counter?
Most counters count characters the way a programming language does. Networks don't. X counts every link as 23 characters and every emoji as 2; Bluesky counts graphemes, so a family emoji counts once; LinkedIn allows 3,000 characters. These tools count the way each network does, using the same code our API uses to check posts before they go out.
Everything runs in your browser. Nothing you type is sent anywhere.
Questions
What people ask
Are these tools free?
Yes, with no sign-up. They run entirely in your browser and don't store or send what you type.
Can I check posts like this automatically?
Yes. SocialsForAI's API runs the same checks on every post, and `dry_run: true` returns each problem with a fix without publishing. See the [docs](/docs).
