What a bio needs to do
A bio is read in a second or two by someone deciding whether to follow, connect or click. In that moment it should answer three questions: who are you, what do you offer or post, and what should the visitor do next. Everything else, including emoji and decoration, is optional.
Character limits by platform
The generator targets these lengths. Platforms can change their limits, so check the current numbers in the app before you paste.
| Platform | Target length | Shape |
|---|---|---|
| Up to 150 characters | 2 to 4 short lines, a few emoji allowed, ends with a nudge to the link | |
| Headline up to 220 characters, plus an About summary | Role, specialty and value in the headline; 3 to 5 first-person sentences below | |
| X (Twitter) | Up to 160 characters | One or two punchy lines, no hashtag spam |
| TikTok | Up to 80 characters | Playful, says what you post and why to follow |
Fill in the form well
- Name: the name you use on the profile.
- Role: be specific. "Pediatric nurse" says more than "healthcare worker".
- Niche or topics: what you post about or who you serve.
- Keywords: words people would search for, plus any call to action such as "book a call".
Add real facts only. If you have a verifiable achievement, include it yourself in the keywords field. The tool will not add numbers, awards or employers you did not give.
Tips for a bio that works
- Put the most important words first, because profile previews cut long text.
- Write for one reader, not everyone.
- Use one clear call to action.
- Keep claims you can back up. "Helping students plan their first resume" is easier to stand behind than a vague superlative.
For a LinkedIn profile, pair this with the Cover Letter Generator when you apply for jobs, and check spelling with the Grammar Checker.
