I built grai because every AI draft I wrote sounded like the same person.
It does one thing: it measures how you actually write, then keeps a model inside that shape. The profile lives in your browser. Nothing is uploaded.
The proof is mechanical. Sentence length variation, openings, endings, signature words, and six structural tells that survive a spellcheck. The thresholds come from 134,522 posts across 1,499 founder profiles.
Founder is $69 once. Agency is $149 with a commercial licence. Studio is $299 per month for white label work with clients. If it does not make your writing sharper in 30 days, one email gets your money back.
