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.

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.

Frequently asked questions

Is AskYourPDF or OpenEvidence better?

OpenEvidence is ahead on 4 of the 9 rows compared, 3 of them about how well it does the job itself. That is a clear lead rather than a tiebreaker. OpenEvidence is built for search, research & academics; AskYourPDF does it well without it being its focus; both have a free plan you can start on. AskYourPDF: Straightforward document chat with citation back to the page, and it handles long PDFs without the usual truncation. OpenEvidence: Built for clinical literature. Answers cite primary medical research, and it is free for verified clinicians.

Is AskYourPDF or OpenEvidence cheaper?

Only one of the two publishes a ladder we have verified, so a like-for-like comparison is not possible yet.

Do AskYourPDF and OpenEvidence both have free plans?

Yes. AskYourPDF: Free, but tightly capped: 1 document a day, 100 pages per document and a 15MB upload limit. OpenEvidence: Free for verified clinicians, ad-supported.

What should I watch out for?

AskYourPDF: A thin layer over a general model, so it inherits that model’s habits. Little here that a general assistant with file upload does not also do. The free tier allows one document a day, so it is a taster rather than a working allowance. OpenEvidence: Medicine only, and access is gated behind clinician verification. No use for a history or engineering student.

How we compare AI tools
Every row is generated from the same record the rest of the site is built on, so this page cannot drift from what we say elsewhere. We separate winner, tie and depends rather than forcing each category into a ranking, and we drop rows where both sides say the same thing. A pick is only called an overall pick when it leads on rows about how well the tool does the job; a lead that rests on price or audience alone is labelled as one. Nothing here is a hands-on test — how we know lists the source and date behind every deciding row.
