  2. Make it sound like you. Choose a tone, add optional keywords or a call to action, and switch emojis on or off.
  3. Choose and copy. Generate five options, check that the wording is true to you, and copy your favorite into your Instagram profile.

What you get

  • Five bio options, each at most 150 characters
  • Friendly, professional, witty, minimal or bold tone
  • Optional keywords, call to action and emojis
  • Copy buttons and a free JSON or Markdown API

What makes a good Instagram bio?

Lead with what you do or who you help. Use specific words that sound like you, keep the details true, and finish with one clear call to action. Line breaks make short phrases easier to scan. Save links for your profile's Links section.

Example bios

Bring your projects together on a link-in-bio page and point your profile to it.

Use the free API

Send about (3–200 characters), tone (friendly, professional, witty, minimal or bold), optional keywords (up to 100 characters), and emoji (1 or 0). Tone defaults to friendly; emojis default to on. Add Accept: text/markdown for Markdown. No key or account is needed.

GET /api/tools/instagram-bio?about=Portrait%20photographer&tone=friendly&emoji=1

Answers contain bios (five strings) and cached. Identical inputs reuse a result for ten minutes without using your allowance. Responses are private and are not cached by your browser. There are four concurrent generation slots and a daily ceiling of 500 generations per server process.

Instagram bios, answered

What is Instagram's bio character limit?

Instagram bios have a 150-character limit. Every returned option is checked on the server, including spaces and line breaks. An oversized option is dropped, never silently cut mid-word. Emoji are counted conservatively so the result fits.

Can I use line breaks?

Yes. Line breaks can separate what you do from your call to action, and they count toward the 150-character limit. The copy button keeps them.

How do I add a link to my bio?

Add your BioFlow page in Instagram's profile Links section. One BioFlow link can bring your projects, shop and social profiles together. The generated text contains no links, leaving room for your message.

How many generations are free?

You get five free generations a day per client address, with five bio options each time. Identical inputs reuse a result for ten minutes without using your allowance. Shared addresses share the limit. The daily window resets 24 hours after the first generation; busy periods may limit availability.

Is there a free API?

Yes. GET /api/tools/instagram-bio?about=your%20description&tone=friendly&emoji=1 returns JSON. Optional keywords can be up to 100 characters. Use emoji=0 to turn emojis off, or Accept: text/markdown for Markdown. No key is needed. The five-generation daily limit also applies to the API, on top of 30 calls a minute and 300 a day.

Do you store my text or bios?

No account, saved history or database record is created. Your description is sent to our AI provider to generate the options. A hashed input key and the result stay temporarily in server memory for ten minutes to avoid repeat calls. The tool's application logs never include your text or bios. Avoid entering sensitive information.
