If you only read one section, make it this one. Rows where both sides say the same thing are left out — the point is where they differ. Where each row came from is listed underneath.
| Category | OpenEvidence | ResearchRabbit | Better fit |
|---|---|---|---|
| What it's built for | Built for clinical literature. Answers cite primary medical research, and it is free for verified clinicians. | Follows citations outward from papers you already trust and keeps alerting you as new ones appear. Strong for finding what you did not know to look for. | Tie |
| Free plan | Yes. Free for verified clinicians, ad-supported | Yes. Free forever, and unusually complete: unlimited searches across more than 310 million articles, unlimited library and collections, and sharing a collection to collaborate. The cap is 50 seed articles and core rather than advanced search settings | Tie |
| Cheapest way to pay | No paid tier — it is free. | $12.5 a month. | OpenEvidence |
| What the paid tiers cost | No paid tier — it is free. |

| What to watch out for | Medicine only, and access is gated behind clinician verification. No use for a history or engineering student. | Owned by Litmaps since May 2025 and overlaps it heavily, down to charging the same $10 and $12.50. Discovery only — it will not read or summarise anything for you, and the free tier stops at 50 seed articles. | Tie |

How we know
Every row that separated these two, and where it came from. Nothing here is a hands-on test — if a line rests on a vendor’s own pricing page, it says so and links it.
| Row | Favours | Weight | Where it came from |
|---|---|---|---|
| Cheapest way to pay | OpenEvidence | Everything else | From each vendor’s own pricing page. Dates and pages are listed below. |
| Sources you can check | OpenEvidence | How well it does the job | From this site’s own catalogue record for each product — compiled by hand, not imported. How a product gets listed |
The prices
OpenEvidence. Read by hand on 4 September 2026, because OpenEvidence cannot be read automatically: Free for verified clinicians, no paid tier — nothing priced to watch openevidence.com/pricing
ResearchRabbit. Read by hand off researchrabbit.ai on 4 September 2026. It is not on the monthly re-check, so confirm there before paying. researchrabbit.ai/pricing
The ratings
The category these two share. Search, Research & Academics — both are listed there in the catalogue, and the fit recorded against each listing is a judgement made here, by hand.
The nine-category grid below. Derived from what each product is listed for, by one script, once per build — so the same pair always reads the same. It is a derivation, not a review.
What this is not
Neither product was run side by side to produce this page. Nobody was paid to appear on it and nothing here is ranked by commission.
To put the same question to both and read the answers yourself, run them side by side — that is a live test, and this is not.
Choose based on what you’re doing
All ten categories, including the ones where neither of these is the answer. These ratings are derived from what each product is listed for, not from running it — a rating here is a reading of the record, and the record is linked.
