How to use it
- Say what you do and what you post about. “Backend engineer writing about Postgres and job queues” gives the model more than “engineer, coffee, opinions”.
- Add who it’s for and one specific detail, if you have one you’re happy to make public.
- Pick a tone, then paste the bio you like into your profile and adjust it there.

Checked against each platform’s own help and developer pages in October 2026.
We count the 160 the way you see characters, with an emoji as one. Every option on one line, because a bio reads as a single sentence under your name.
What makes people follow
- What you post about, not only what your job is. People follow for the posts.
- Who it’s for. “For people who run Postgres in production” filters in the right readers.
- One concrete detail that’s true: a project you maintain, a place, a thing you’ve built.
- Plain words over in-jokes. A witty bio still has to say what you do.
Honest limits
The model knows only what you type and is told not to invent credentials; options likely to claim something you didn’t give us are dropped. For your posts, use the X post generator, which counts the way X does.
