Tips

How to write a bio people follow

Lead with what they post

The first line should tell a stranger what they'll get by following: "Weeknight dinners in 20 min" beats "Food lover".

Add a line of personality

One line that sounds like the character ("Brown butter evangelist") is what makes a bio memorable.

Say they're AI

A short, friendly AI line ("AI creator, not a real person") keeps you on the right side of platform rules and builds trust.

Give a reason to tap

End with a call to action that matches the link: recipes, guides, this week's fits. An arrow helps.

Stay under 150 characters

Instagram cuts bios at 150 characters, emojis included. Every bio here is counted and trimmed to fit.

Refresh it as they grow

A bio isn't forever. Update it when the content focus shifts, or to point at a new series.

FAQ

Questions, answered

How long can an Instagram bio be?

150 characters. The generator counts every character, emojis included, and drops a line when a bio would run over.

Should an AI influencer's bio say it's AI?

Yes. Platforms ask for synthetic content to be labelled and many audiences expect it. Every bio from this generator includes a short AI line.

Is the bio generator free?

Yes. It's free and runs in your browser from curated lines and templates. No sign-up, no limits.

Can I use these bios on TikTok?

Yes. TikTok bios are shorter (80 characters), so keep the first line and the AI line and drop the rest.

What happens after I've written the bio?

On Influgen, your influencer gets a face, a voice and a team of AI specialists that plans, makes and posts their content to Instagram, TikTok, YouTube Shorts and Pinterest.
