| What to watch out for | Paid from the start, though the trial takes no card. The tiers differ mainly by monthly credits — 225,000, one million and two million — rather than by features, so the question is how much you write. Prose has a recognisable register you will want to edit out. | Academic English only — it is the wrong tool for a blog post. The yearly prices on the cards are 40 per cent offers on Premium and Confidential Data, whose standing rates are $80 and $500, and the free tier stops at 5,000 words a month. | Tie |

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. Writing, Communication & Language — 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.
