Examine is the best place to read the trials behind one compound. Precis is the record of what researchers say on tape, checked against each other, timecoded to the minute. They answer different questions, and the table below is where they split.
| Precis | Examine | |
|---|---|---|
| Source | 3,700+ hours of recorded interviews with 380 researchers and doctors, plus 48,500+ research studies | Randomised trials and meta-analyses |
| Unit of proof | A named person and a minute | A graded outcome |
| Longevity depth | 44 topics, one verdict per claim | 4 interventions under “Longer Lifespan”, last updated Nov 2025 |
| Credit to who said it | Yes | None by design: “We are not gurus” |
| Free layer | Score, stances, every timecode | Grades locked |
| Price | $79/yr | $198/yr or $29/mo |
| Better for | “What should I do?” | “What does the trial say?” |

Honestly: if you want to go deep on the evidence for a single compound — every trial, dose-response, and interaction — Examine's database is more thorough than any consensus summary, and worth the subscription for researchers, dietitians, and hardcore self-optimizers. Precis isn't trying to replace the study database. It answers a different question: what the record says on one claim, and where it splits.
Three reasons. First, the free layer. On Precis the verdict, every counted mention and every timecode are open. On Examine the grade is the product, and it sits behind Examine+. Second, the disagreement problem. A trial grade does not tell you why one researcher picks one magnesium form and another picks a different one. Precis shows where the sources agree, where they split, and the minute each claim was said, so you are not refereeing five podcasts yourself.
Third, longevity is where Examine is thinnest and Precis is deepest. Examine files four interventions under “Longer Lifespan”, last updated in November 2025. Precis scores 44 longevity topics, each one built from 3,700+ hours of recorded interviews with 380 researchers and doctors, plus 48,500+ research studies and refreshed as new episodes land.
