The count updates as you type.
3
Copy or schedule
Keep editing, or take it into the composer.
Character limits by platform
The limits NioConnect checks against. Your server or account may differ.
| Platform | Limit | Note |
|---|---|---|
| Bluesky | 300 | Counted in visible characters |
| Mastodon | 500 | Default; each server sets its own |
| X | 280 | Default account; links and some characters count differently |
| Telegram | 4096 | Text message; captions are shorter |
| Discord | 1980 | NioConnect checks 1,980 to leave room for a trailing link; Discord itself allows 2,000 |
| 300 | Post title; the body allows far more |
Check, then schedule
The composer runs the real platform checks on every channel before a post is queued.
Questions about this tool
Is this tool accurate?
It uses widely published default limits and a plain count. A server, an account type or a recent platform change can differ, so treat it as a quick check. The composer runs the real platform rules before a post is queued.
Do I need an account?
No. The tool runs in your browser and nothing you type is sent anywhere.
