This free AI bio generator writes three ready-to-paste bios, one professional, one conversational and one creative, for the platform you pick. It knows the character limit for ten platforms, from Instagram and LinkedIn to Discord and GitHub, and shows a live count on each bio. No signup is needed.
It is built for anyone filling in a profile box: creators, freelancers, job seekers, founders and streamers. You give it your name and role, choose a tone, and compare three angles side by side instead of rewriting one draft over and over.
How to write a bio with the AI bio generator
- Enter your name and your role, for example "Priya Shah, UX designer for fintech apps".
- Choose the platform: LinkedIn, Twitter/X, Instagram, TikTok, YouTube, Twitch, Discord, Facebook, GitHub or Website/Portfolio.
- Pick a tone: professional, friendly, bold, witty or minimalist.
- Set the length (short, standard or detailed) and whether to add emojis.
- Click Generate Bio and read the three versions with their character counts.
- Copy the one you like, or regenerate with a different tone.
Character limits the tool writes to
Each bio is written to the platform's limit and shown as a count, turning red if a draft runs over:
- TikTok: 80 characters
- Facebook: 101 characters
- Instagram: 150 characters
- Twitter/X and GitHub: 160 characters
- Discord: 190 characters
- LinkedIn: 220 characters
- Website/Portfolio: 250 characters
- Twitch: 300 characters
- YouTube: 1,000 characters
Emojis are only added when you ask for them, except that one or two may appear on Instagram, TikTok, Twitch or Discord, where they fit the culture. Instagram and TikTok bios may end with a niche hashtag or two; other platforms get none.
Instagram, LinkedIn and professional bios
For an Instagram bio, the short limit means one hook and one reason to follow; pair the friendly or witty tone with emojis on for a creator profile. For a LinkedIn or other professional bio, choose the professional tone and the detailed length so there is room for an achievement and a call to connect. For a business bio on a website, the Website/Portfolio option gives you up to 250 characters for a clear statement of what you do. After each run the tool also shows four tips for the chosen platform, such as front-loading keywords on YouTube or listing your stack first on GitHub.
The completeness checklist
Below the results, a quick checklist scores the first bio. It looks for simple signals: whether your role appears, whether there is a hook or personality line, and, on platforms with more than 160 characters, whether there is an achievement and a closing call to action. On short platforms it only checks the first two, since an 80 or 150 character bio cannot fit everything. It is a keyword check, not a quality grade, so a bio can read well and still miss a box.
Making an AI bio sound like you
Treat the output as a strong first draft. Swap in one real detail only you know, a client, a number or a hobby, and cut any phrase you would never say aloud. If you need a profile headline or an ad line rather than a bio, the AI headline generator writes ten short lines at once.

There is no dating app option, but you can pick Website/Portfolio or Instagram for the length you need and choose the friendly or witty tone. Edit in real details before using it.
Why are there three bios?
