Rayyan
Built for systematic reviews — thousands of abstracts screened by a team, with blinding and conflict resolution built into the workflow.
Highlight the passage that lost you and get it explained at the level you ask for, in place, without leaving the paper.
Explainpaper is the better answer when the job is what it was built for rather than what the pick above does broadly.
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 |
|---|---|---|---|
| What it's built for | Rayyan | 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 |
| Fit for search, research & academics | Rayyan | How well it does the job | Both products are listed under search, research & academics in the catalogue, and this is the fit recorded against each listing. Everything listed under search, research & academics |
| Cheapest way to pay | Rayyan | Everything else | From each vendor’s own pricing page. Dates and pages are listed below. |

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.
