Facebook's bio field (101 characters) is short and shows up prominently on both personal profiles and business Pages, right under your name. This generator writes tight variants for either use case, based on the tone and niche you choose.
Free Mode — bios are written by a rule-based engine running in your browser, not a live AI API call. Here's exactly how that works.
No sign-up. No email. Bios generate locally.

A personal profile bio tends to work best with a warmer, more personal tone since friends and family are the primary audience, while a business Page bio should read closer to a tagline — what the business does and who it's for, in one short line.
Because the field is so short, avoid repeating your business name in the bio itself (it's already displayed above); use the space instead for the one thing a visitor should know that your name doesn't already tell them.
These four examples are real output from this page’s own engine, first variant only, with inputs listed so you can reproduce them. The engine is rule-based: it matches your profession to a keyword group, fills a template with a tone-specific connector and closer, and cuts the result at the character limit. It does not read the draft back, which matters most on Facebook, where the 101-character limit is short enough that every one of these drafts was trimmed.
Input: name “Nina Patel”, profession “small business owner”, interests “handmade candles, local pickup”.
91 / 101 characters. The full draft was 114 characters, so the engine cut off “pickup. / Let's connect.”. The first line spends 33 characters repeating the business owner’s name and title. As the section above notes, a Page already shows the name directly above the bio, so that line is the first to delete.
Input: name “Greg Hall”, profession “plumber”, interests “emergency repairs, family business”.
98 / 101 characters. The full draft was 128 characters, so the engine cut off “family business. / Send snacks.”. The draft ends on a dangling “·” with the second interest missing. The Funny connector is also long, so the bio runs out of room before it reaches the part that is about plumbing.
Input: name “Fatima Noor”, profession “community organizer”, interests “neighbourhood events, volunteering”.
95 / 101 characters. The full draft was 138 characters, so the engine cut off “events · volunteering. / One step at a time.”. The cut left a bio that ends on “neighbourhood”, with “events · volunteering” gone. For a community organizer the interests are the substance, so this is the wrong thing to lose.
Input: name “Ben Ward”, profession “real estate agent”, interests “first-time buyers, local homes”.
98 / 101 characters. The full draft was 130 characters, so the engine cut off “· local homes. / Enquiries by DM.”. The Luxury tone is a poor fit for a local agent’s page, and the cut removed the second interest and the “Enquiries by DM.” closer. This draft would be much stronger as a single plain sentence.
The four drafts ran 114, 128, 138 and 130 characters before trimming, so they were 13, 27, 37 and 29 characters over. In each case the engine removed the end of the bio, which is where the interests and the closer sit.
Deleting the first line by hand recovers a lot. For Nina’s draft it saves 34 characters (the line plus its line break), taking her from 114 to 80, and Ben’s drops from 130 to 101, which fits exactly. Greg’s (108) and Fatima’s (104) are still a few characters over, so each needs a word or two trimmed as well. That arithmetic is the whole lesson of this page: on Facebook, the name and title line is the most expensive part of the bio and the least useful, because the name is already on screen. The other limits are compared in the bio character limits reference.
For a business Page, aim for one line that says what you do and who it is for. For a personal profile, one line a friend would recognise as you. Illustrative rewrites of examples 1 and 3, from the same inputs:
Hand-written illustration, not tool output: 57 / 101 characters.
Hand-written illustration, not tool output: 47 / 101 characters.
Both avoid repeating the name, and both keep the interests the engine cut. If the Page also has a link or CTA button, let that carry the call to action.
The five-part Bio Score (clarity, niche, personality, keywords, call to action) gives the first variants above 76, 71, 76 and 71. Those numbers look respectable even though every draft was cut off, because the score checks the trimmed text and each one still has a profession and an interest. A score in the 70s on Facebook therefore does not mean the bio reads well. The tool shows an average across all seven platforms, which hides this further, so judge the 101-character draft by reading it.
Count the characters first: the tool shows a count under each variant, and a draft over 101 has been cut. Then check that the bio does not repeat the name shown above it, that it ends on a complete word, and that it says one thing a visitor would not already know from your name and photo. Finally, match the tone to the audience: a business Page is usually better served by a plain, descriptive line than by a playful one. If a draft fails any of these, edit it by hand rather than regenerating, because regenerating changes only the wording of the connector, value line and closer, not the structure that makes a draft too long.
101 characters for the short bio field shown under your name on both profiles and Pages.
Yes, though Facebook's culture generally rewards a more restrained, professional tone than Instagram or TikTok, especially for business Pages.
No — the short bio under your name is separate from the longer About section, which has its own, much larger character allowance.
