Bio Generator (Instagram, TikTok, LinkedIn)

A good bio says who you are and why someone should follow, in very few characters. Enter your role, interests, location and a call to action, pick the platform and tone, and this bio generator builds ten options from original templates, each counted against the widely reported limit: 150 characters for Instagram and Threads, 80 for TikTok, 160 for X and 220 for a LinkedIn headline. It also writes a longer LinkedIn About section.

How to use this tool

1. Choose the platform; the limit is set for you.
2. Enter what you do, your interests (comma-separated), location and call to action.
3. Pick a tone, how many emoji, and optionally a styled name.
4. Copy the best bio or another option; change the suggestion set to see the templates in a different order.

Formula

Bio = template lines filled with your details; optional lines are dropped from the end until it fits the limit

Lines that need a detail you left empty are skipped. If a bio is still too long, optional lines (location, call to action) are removed one at a time from the end, and the table says “Shortened”. Characters are counted in UTF-16 units, so most emoji count as two; for X, Latin letters count 1 and emoji or CJK characters 2, as in X posts. The limits are the widely reported ones, not figures the platforms publish. Emoji are matched to keywords in your role and interests, such as ☕ for coffee or 🎨 for illustration.

Example

For a freelance illustrator in Portland, OR who likes coffee, picture books and hiking, the minimal Instagram bio is “Freelance illustrator. / Portland, OR.” (36 characters). On TikTok the first professional bio is 83 characters, so the call to action is dropped and it fits at 66.

Tips for a better bio

Lead with what people can expect from you, not just your job title. Keep one clear call to action, and put the link in the platform’s link field. Styled letters look striking, but screen readers may read them letter by letter or skip them, and in-app search may not find them, so keep your real name plain in the name field. Check the limit in the app before you save, because platforms change them.
