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 | ChatGPT deep research | Consensus | Better fit |
|---|---|---|---|
| What it's built for | Long autonomous research runs that produce a cited write-up. Useful for scoping a topic before you commit to reading. | Searches published papers and tells you how many of them support a claim, which turns a yes-or-no question into a count you can inspect. | Consensus |
| Fit for search, research & academics | Strong fit | Built for this | Consensus |
| Free plan | Yes. A small number of deep research runs on the free ChatGPT tier | Yes. Free plan at $0: basic paper search, 15 Pro messages a month and up to 3 Deep reviews a month, though the same card also describes the free tier as being without AI analysis | Tie |
| What the paid tiers cost |
|
| Tie |
| What to watch out for | Web-first rather than database-first. Verify every citation before it enters a bibliography. There is no separate deep research plan: more runs come with a ChatGPT subscription. | 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. | Tie |
| Who it is usually for | students, researchers, working professionals | researchers, students | Tie |
| Made by | OpenAI — San Francisco, US. | Consensus — Boston, US. | Tie |
Consensus is ahead on 2 of the 7 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 | Consensus | 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 | Consensus | 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 prices

Consensus. Read by hand on 4 September 2026, because Consensus cannot be read automatically: Both consensus.app/pricing/ and the help-centre article return 200 with the plans drawn in JavaScript; the browser step found no amounts either. Runs 16, 17, 19 and 20 all agree. Priced by hand from the in-app upgrade panel, which is where the Individual plans are actually shown; the Team and Enterprise tab is still uncovered. consensus.app/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.
