An X bio is 160 characters. That single constraint is why bio advice is worth taking seriously: roughly one sentence has to carry a searchable keyword, a reason to be believed, and a reason to press follow. This tool asks a language model to score a public bio on exactly those three dimensions - SEO görünürlüğü, Güven ve itibar and CTA gücü, each 0-100 - and to write 3 replacements, every one of them inside the 160-character limit.
Those three numbers are a model's judgement, not arithmetic on a counter. Run the same bio twice and they can move by a few points, and two different accounts can be scored inconsistently in a way a formula would not be. That is a real limitation and it is why the page shows the model's written reasoning for each dimension next to the score rather than the score alone. It is also why this tool needs a live model connection: when it cannot reach one, it returns an unavailable message and no score at all.
Who this matters for is measurable. Across the 45,308-account sample PlayerSells measured from its 18,486,455-account X index on 24 August 2026, the median account has 550 followers and 2,046 followers is already the 75th percentile. At that size a profile visit is a scarce event, most visits come from a single post rather than from search, and the bio is the only thing standing between a visit and a follow. The accounts with the least to gain from a rewritten bio are the 89,454-follower ones at the top of the index, who are followed for who they already are.
The 160-character limit is X's. The three dimensions and the 3 alternatives are this tool's own design, and the scores are generated by a language model at request time rather than computed from a formula. Follower percentiles are our own measurement, taken on 24 August 2026 over a 45,308-account sample of the 18,486,455 X accounts we index, and describe that index rather than every account on X.
