# Instagram bio generator

Say what you do and for whom, pick a tone, and get five bio drafts of 150 characters or less, or start from the bio formula and eight templates below.

## Write a bio that fits

Your bio is the first thing people read after your name and photo, and it has 150 characters to tell them why to follow. The generator writes five drafts in the tone you pick, each within the limit, so you can compare angles instead of cutting a long draft down word by word. Every draft shows its length, counted like our character counter.

If the AI part is switched off, the bio formula and the eight templates on this page work the same way. Fill in the brackets with your own details and you have a first draft in a minute.

## Tips for a better Instagram bio

- Lead with what you do. People decide in a second, so the first words should answer "what is this account?"
- Write for one audience. "For new runners" is clearer than "for everyone who loves sport".
- Use line breaks. Two or three short lines are easier to read on a phone than one long sentence.
- Point to one link. Say what people get from it, such as a booking page, a shop or the latest video.
- Keep it true. Only mention numbers, awards or results you can show.

## From bio to a full profile plan

A clear bio brings people to your profile; regular posts keep them there. In PostBoost you can write captions with AI, plan them on one calendar, and publish to Instagram and your other networks.

## How to use

1. Describe what you or your brand do, and for whom, in a sentence.
2. Pick a tone, and whether you want emoji and a call to action.
3. Generate five bios; each shows its length against the 150-character limit.
4. Copy the one closest to your voice, edit it, and paste it into Edit profile on Instagram.

## FAQ

### How long can an Instagram bio be?

Instagram allows up to 150 characters in a bio. Every draft from this generator fits that limit as the character counter counts it, where most emoji count as 2.

### What should an Instagram bio say?

What you do, who it is for, one detail that sets you apart, and what people get from the link in your bio. The bio formula on this page follows that order.

### How does the AI bio generator work?

When it is switched on, your description and options are sent to PostBoost and our AI provider, which writes five different bios. The same request returns the cached result, and each visitor gets a few free generations per day, shared with the other AI tools.

### Can I use the bios as they are?

Treat them as drafts. AI text can be generic or get details wrong, so edit the bio until it sounds like you and only keep claims you can back up.

### Can I use line breaks and special fonts in my bio?

Yes. Line breaks help a bio read like a short list, and the drafts use them where it helps. Fancy text from the fancy text generator also works, but styled letters can count as two characters each, so check the length again.

### Why is the generator form not shown?

The AI part can be switched off, for example when the monthly free allowance is used up. The bio formula and templates still work, and a free PostBoost account lets you write posts with AI inside the app.
