| Tie |
| What to watch out for | Explains what a passage says rather than whether it is right, and a confident explanation of a flawed method reads exactly like a good one. The free tier is unlimited but runs on weaker models, so what you pay for is the quality of the explanation rather than more of it. | A map is a prompt to read, not a substitute for reading. The free tier stops at 2 maps of 100 articles each, so a real review needs Pro, and Pro is priced on separate education and commercial tabs.

Litmaps is ahead on 3 of the 8 rows compared, 2 of them about how well it does the job itself. That is a clear lead rather than a tiebreaker.

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 | Litmaps | 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 | Litmaps | 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 |

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.
