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 prices

QuillBot. Read by hand on 4 September 2026, because QuillBot cannot be read automatically: quillbot.com refuses automation (403) on both /premium and the pricing page, and the help-centre alternate carries no prices. Three refusals across runs 16, 17 and 21. Priced by hand from /premium on both billing terms; the Team Plan carries no published price. quillbot.com/premium

TextCortex. Read by hand off textcortex.com on 4 September 2026. It is not on the monthly re-check, so confirm there before paying. textcortex.com/pricing

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.
