An X bio that tells people why to follow you.
Fill in what you do and who it's for, and get five short bios to edit, each counted against the 160-character limit.
The short answer
A good X bio tells a stranger who you are, who you help and why to follow you, in 160 characters or fewer. People usually look at it right after seeing one of your posts, so it needs to back up what they just read.
What works
- Say what you post about. People follow for what they'll get.
- Name who it's for. "For B2B founders" filters in the right people.
- Add proof or one human detail. A small true thing is more memorable than a list of titles.
- Skip the buzzwords. "Passionate serial entrepreneur" could be anyone.

Questions
How long can an X bio be?
160 characters.
What should a founder put in an X bio?
What you're building, who it's for, and one piece of proof or a human detail. A link to your product goes in the website field, where it doesn't use up your bio.
Do links in my bio count?
Yes, they use up the 160 characters, so put your main link in the website field.
Does this use AI?
No. It uses fill-in structures in your browser, and nothing is sent anywhere.
