underslop vs the alternatives

Four pages that compare underslop to the tools people actually search for: the rewriter everyone reaches for, the detector every classroom knows, and the humanizer category as a whole. Every page states what the other tool does, what it costs where a price is verifiable, and where underslop is different. Nothing on these pages links to competitor sites.

What these pages cover

Detectors. Statistical classifiers that guess whether a model wrote a text. The GPTZero page covers the best-known tool in the category and the limits of a style guess.

Rewriters. QuillBot is the one most students name; the page covers what it does well and where its subscription leaves a machine-written draft.

Humanizers. A category of tools that rework machine text, with claims that rarely survive a price check. The roundup covers five vendors.

Where underslop fits. Each page ends with the same comparison: a tool that detects by named tells, rewrites with provenance, guards facts, and keeps an audit trail.

How to read these pages

Each page follows one shape: what the tool is, what it does well, what it does not do, a side-by-side of features, and the verdict.

Prices are quoted as of 11 August 2026 from vendor pages, or marked third-party where they come from elsewhere. Where a page was unreachable or sources conflict, the page says so and no number is invented.

A feature is listed only when the vendor documents it. A vendor blog post is marketing, not documentation, and these pages do not take it as proof.

Methodology

We describe each tool from its own documentation and price it from its own pricing page when one is reachable.

We verified the figures on 11 August 2026 in a single research pass, and the pages carry that date so a reader can judge how stale they are.

Where a claim depends on a measurement we did not run, the page says so. None of these pages sells a benchmark score, because a benchmark we cannot reproduce is a number we should not print.

Who wrote these pages

underslop wrote them, and underslop is the product the pages compare against. That is a conflict of interest, so it sits at the top of the methodology instead of the bottom.

The rule we hold ourselves to: other tools get their own descriptions and their own prices, their strengths get named first, and the comparison rows are features the vendor documents. We do not link to competitor sites, so a reader who wants a vendor page finds it with a search.

If you spot a price that has moved or a feature we misread, use the contact page. The pages get corrected and the date at the top gets bumped.

Where underslop fits

underslop detects, rewrites, and keeps the record. It reports the AI tells in a draft by name, rewrites with your voice, guards the facts, and logs every edit.

The price is public and simple: $0.10 per 1,000 words, with a free tier at 500 words per run.

The pages in this section exist because alternatives are usually compared by vendors who sell the same thing. These pages are the version of that search written by someone who starts from the draft, not from the sale.

Pricing note: all prices on these pages are as of 11 August 2026, from vendor pages or marked third-party. Where a price could not be verified, the page says "not publicly available" instead of guessing.
