What to watch out forFewer features than a dedicated editing tool, by choice. There is one paid tier, and the $30 of AI credits it includes each month is worth more than the subscription at either billing term, so what you are buying is model access more than software.Rewriting someone else’s sentence is still their sentence, and universities treat it that way.

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 1 row that decided this page, with the source for each.
RowFavoursWeightWhere it came from
Cheapest way to payQuillBotEverything elseFrom each vendor’s own pricing page. Dates and pages are listed below.

The prices

Lex. Read by hand on 4 September 2026, because Lex cannot be read automatically: lex.page/pricing returns 200 with the plans drawn in JavaScript. Priced by hand from the single Lex Pro card on both billing terms; the free tier is not shown on that page. lex.page/pricing

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

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.

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.
