AI Twitter / X Bio Generator On-device AI

Fill in who you are and what you post about → get 3 Twitter/X bio variations inside the 160-character cap. On-device AI — your info never leaves your browser.

On-device AI not available. This tool needs Chrome (or Edge, Brave, Arc) with Gemini Nano enabled. First use triggers a one-time ~1.5GB model download.

Your Twitter/X bio is the only profile-level pitch you get. Visitors scan it for 2 seconds before deciding to follow. The winning format is tight and specific: what you do + who you are + a hook or CTA. This tool generates 3 variations so you can pick the sharpest angle. On-device AI, zero cost.

How long can a Twitter/X bio be?

160 characters. No line breaks — everything wraps on a single line. Use em-dashes, pipes ( | ), or bullets (·) to visually separate ideas.

Should I put @mentions in my X bio?

Yes for companies you work at or communities you're part of. It creates hoverable links and signals affiliation.

Do hashtags work in an X bio?

They're clickable but rarely drive discovery from a bio. Most pros skip them unless you have a branded hashtag you own.

Does this run on my device?

Yes — Chrome's Gemini Nano runs locally. Your name, niche, and bio never leave your browser.
