What to watch out forDeliberately limited — it will not answer what your documents do not cover, and cannot tell you whether they are any good. Paid headroom comes from a Google AI subscription rather than a plan of its own.

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.

Gemini Notebook. Read by hand off one.google.com on 4 September 2026. It is not on the monthly re-check, so confirm there before paying. one.google.com/ai

Petal. Read by hand on 4 September 2026, because Petal cannot be read automatically: Plans live at /resources/pricing, not /pricing, which 404s. Still drawn in JavaScript, so transcribed by hand; re-verify the same way. petal.org/resources/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.

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.
