How long can an Instagram bio be?
150 characters, including line breaks and emoji. Instagram counts an emoji as one character even though some text editors count it as two, so this tool counts in code points to match what Instagram will actually accept. The display name above the bio is a separate field with its own 30 character limit.
Do keywords in my Instagram bio help people find me?
Not the way most advice implies. Instagram matches a typed search against the username and the display name. The bio is what somebody reads once they have already arrived. So the keyword that makes you findable belongs in the 30 character name field, and this tool checks that field specifically because it is the one most accounts waste by repeating their own handle.
Does the tool need my password or an Instagram connection?
No. It reads the same public profile anybody can see logged out, through our own reader. There is nothing to connect, no OAuth, no permissions and no password. You can also paste bio text instead, in which case nothing leaves your browser except the text itself and no profile is read at all.
Is this AI generated?
The scoring is not. Every check is a rule you can read in the result: character count, first line length, whether the link field is set, whether the name field carries a keyword, whether a bait phrase is present. That is why it works instantly and always returns the same answer for the same bio. A model is used only to rewrite the suggested bios into finished copy when one is configured, and when it is not, the tool falls back to fill-in templates and the score is unchanged.
Why does it care about line breaks?
Because Instagram renders them. A bio typed as one paragraph and the same words split across 5 lines are different objects on the profile: one gets scanned, one gets skipped. The tool flags a long single-line bio and also flags going too far the other way, since a bio that is all short lines and emoji stops carrying information.
What counts as a good score?
0 and above is poor, 35 and above is weak, 55 and above is workable, 70 and above is strong, 85 and above is excellent. A check we could not run, such as the link field when you pasted text rather than giving a username, is left out of the calculation entirely rather than scored as a failure. Marking down a bio for a measurement we chose not to take would be inventing a problem.
Can I grade a bio I have not published yet?
Yes, and that is what the paste box is for. Draft it, paste it with your intended display name, and you get the character count and every structural check before it goes anywhere near your profile. It is also the way to grade a private account, whose bio is not publicly readable.
