Bio Generators
Free Social Media Bio Generator
Draft a bio that fits Instagram’s 150 characters or a TikTok-ready 80, from a short description of you and the tone you choose.
Two platforms, two shapes
The tool writes for Instagram and TikTok. An Instagram bio comes back as up to five short lines within 150 characters. A TikTok bio is two short lines within 80 characters, so it fits whichever limit your account has. Emojis and line breaks count in both, and a draft that runs over is discarded, not shown.
Example input
Description: “Personal trainer in Cardiff, strength training for women over 40, online and in person”. Tone: inspirational. On Instagram you’d get lines for who you help, where you are and how to book. On TikTok the same description becomes two lines: what you post and why to follow.
Questions about this tool
Instagram and TikTok. For a YouTube channel, use the channel description generator, which writes a longer About text.
Keep the message the same and change the length. Say who you help and what to do next in both, and drop the extra detail on TikTok, where there’s less room.
Treat it as a first draft. The AI doesn’t know your business, so check facts, names, prices and claims, and change anything that doesn’t sound like you.
Yes. The AI tools are free with a fair-use limit per person and per day, so everyone can use them. If you reach it, the tool tells you when to try again.
