Watch out: Explanations are only as good as the paper is clear, and it will paraphrase confidently past a passage it has not understood. Paid tiers are metered in credits rather than papers, and the jump from the entry tier to the next is more than five times the price.

Watch out: The consensus meter reflects the papers it found, not the state of the field. Deep reviews are the metered resource — 3 a month free, 15 on Pro, 200 on Deep — so that is what decides the tier rather than how much you search.

Built for this. Breaks a paper into structured cards — aims, method, findings, limitations — instead of one block of summary, which makes skimming a stack of them practical.

Watch out: Structure comes from the paper being conventionally written; it copes badly with anything that is not. The free tier stops at 10 summaries, so a reading list of any size needs the paid plan.

Fit
Whether a tool is built for this job, a strong fit for it, or
able to do it without that being its focus.
Free plan
Whether there is a tier you can keep using rather than a
trial that expires.
The order
Fit first, then a free plan, then alphabetical. There is
no score, no weighting we decline to publish, and nothing on this site a company can buy.
Questions
What is the best ai for analyzing research papers?
There is no single answer, which is why this page lists 8 rather than one: Scite, Elicit, SciSpace, Consensus, Scholarcy, Gemini Notebook, Petal, Claude research mode. 5 of them are built for this kind of work rather than able to do it. Start with a free one.
Which of these have a free plan?
8 of the 8: Scite, Elicit, SciSpace, Consensus, Scholarcy, Gemini Notebook, Petal, Claude research mode. Free means a real free tier you can keep using, not a trial that expires.
How was this list chosen?
By hand, from the 750 products this site tracks, and it is checked against the catalogue on every build — a product renamed or removed breaks the build rather than quietly disappearing from here. Nothing on this site can be paid for: no listing, no position, no wording.
