How GPTypo works

A false positive shield for human writers

AI detectors flag human writing as AI more often than they should. GPTypo is built for the writers who keep getting caught. Scan your draft, see what trips detectors, fix it. If it still gets flagged, share a verified proof of your score.

01Workflow

The whole product is one short loop: scan, review, fix. If you ever need to defend the writing afterward, share a proof report.

1
Scan your writing
Paste your draft, scan a selection from any page, or use the Chrome extension to scan inline while you write. The scanner returns a score from 0 to 100, where 100 is fully human.
Free tier scores instantly using a 5-signal local heuristic. Pro tier verifies with a fine-tuned neural model.
2
See what trips detectors
Each sentence is scored individually. Flagged sentences come with reasons: missing human texture markers, uniform sentence lengths, generic phrasing, and other patterns detectors look for.
Reason chips show you why, not just what. Hover any reason for a plain-language explanation.
3
Fix it, in the words you'd actually use
Click a flagged sentence, get an AI rewrite suggestion that preserves your meaning while breaking the pattern. Replace it in place if you're scanning from Gmail or another writeable source. Copy if you're scanning a static page.
Suggestions are on-demand. Nothing rewrites until you ask.
02Where it works

The Chrome extension works on the surfaces writers actually use. Replace works in writeable fields. Read-only pages get Copy.

03Free vs Pro

Both tiers use the same workflow. The differences are in the scoring engine, the word budget, and whether your scans can be shared as verified proof reports.

04What GPTypo is not

GPTypo does not try to disguise AI-generated writing as human. Tools that paraphrase AI output to evade detectors are a different category, and detectors actively train against them. GPTypo is for the inverse problem: writers whose human writing keeps getting flagged anyway.

GPTypo is a human-in-the-loop editor. Scoring is the start; the rewrites and the share-a-proof loop are the rest of the product.
