Pricing

Every dollar we take comes from someone who uses Precis: Pro, or the one-off $49 health assessment report.
Pro covers the parts that cost us money each time you use them: AI answers, chat, and photo and lab reads.
No brand pays to be mentioned or scored, so we have no reason to favor one bottle over another. Why I built it this way.

Questions
The people who use it. We run no ads, take no sponsorship, use no affiliate links and sell no supplements. No researcher, show, publisher, YouTube or Google is affiliated with Precis or endorses it. How we stay independent.
With no account you get every report's public page on all 44 topics, with the score, the stances and every timecode. You also get 1 Ask question a day. A free account adds full reports: dose, form and timing, with the receipts, ask questions: 3 a day, save your stack, stack check detail: doses, interactions, what to switch to, read your stack from a photo of the bottles: 1 a day, clip searches: 3 a day, and stack checks: 30 a day.
It answers fast, but it rarely tells you where the answer came from. Every claim here links to the interview and the minute, with the name of who said it, so you can hear it yourself. Our AI writes the answers from interviews we have read, and links the ones it draws on. Reports print only what someone said on tape.
No. Precis reports what researchers say in public interviews. It is an information tool, not a medical provider. Every claim links to its video and timestamp so you can check it. Talk to your doctor before you change your health routine.
