ZeroGPT's free tier made AI detection accessible. TextSight adds the next step — a one-click humanizer to rewrite the flagged sentences, plus a 0-100 Humanization Score that tells you when the draft is actually ready.
ZeroGPT made AI detection accessible. Their free tier is the reason most people first tried an AI detector at all — no signup, paste-and-scan, instant verdict. For a quick check, that's still the right tool.
The product gap shows up the moment you need to do anything with the result. ZeroGPT gives you a percentage and stops. There's no humanizer. There's no sentence-level highlights ranked by suspicion. There's no Humanization Score to tell you how close you are to a passable draft. You get a verdict, not a workflow.
TextSight ships the full loop: detection, sentence-level highlights, a one-click humanizer with three intensity modes, and a 0-100 Humanization Score that tells you how natural the text reads — recomputed after every rewrite so you can watch the score climb. Same scan, same tool, same subscription.
And the free tier still works: 3 scans per day on TextSight, no signup needed for your first scans. For occasional checking, the free tier is enough. For sustained writing work, paid plans start at $9.99/month Starter.
ZeroGPT is detection-only. The moment your scan returns a flagged result, you need a second tool to actually fix the content. The free-tier-as-entry-point loses its edge once the workflow extends past the verdict.
Most ZeroGPT scans return a single overall percentage and a paragraph-level color. You don't get a ranked list of which sentences are the most-AI-flavored — so when you start rewriting, you're guessing where to focus.
ZeroGPT's accuracy is acceptable for clearly-written AI prose but degrades on edited content, technical writing, and shorter snippets. Independent benchmarks have flagged false-positive issues on human-written technical content.
The paid tier ($9.99/mo) unlocks higher word limits and removes ads. It doesn't add a humanizer, sentence ranking, or a Humanization Score. You're paying for volume, not for a richer workflow.
ZeroGPT focuses on one thing — AI detection — and skips adjacent features other tools bundle. For light personal use that's fine. For any sustained writing pipeline, you'll be stacking subscriptions.
Pricing reflects annual billing rates as of May 2026. Self-reported accuracy from each vendor's pricing pages.
Honest about the friction. There's no data migration between TextSight and ZeroGPT — switching means starting fresh on a new account.
Different shapes. ZeroGPT's free tier is rate-limited per IP with ads — unlimited daily scans but cluttered. TextSight's free tier is 3 scans per day with the full feature set (humanizer, Humanization Score, sentence ranking). For casual one-off checks, ZeroGPT wins. For sustained workflow, TextSight's free tier is more useful.
TextSight bundles the humanizer and Humanization Score. ZeroGPT Premium at $9.99/mo is detection-only. Add a humanizer subscription ($15-25/mo) for an equivalent workflow and the total exceeds TextSight Pro at $14.99/mo.
TextSight reports up to 99.2% accuracy in our internal benchmark. ZeroGPT's published accuracy varies — they cite 98%+ on certain content types but independent benchmarks have flagged false-positive issues on human-written technical content. We publish our methodology openly at /accuracy-methodology.html so you can evaluate the test setup directly.
TextSight is English-focused. It works on other Latin-alphabet languages but accuracy drops outside English. ZeroGPT has broader multilingual coverage — if Asian, RTL, or non-Latin scripts are central to your workflow, ZeroGPT remains a better fit.
Yes. Many writers use ZeroGPT as a quick second-opinion checker after a TextSight rewrite. They're sold separately and there's no conflict in running both.
A 0-100 measurement of how natural the text reads. TextSight computes it on every scan and every rewrite, so you can watch your draft's score climb as you edit. ZeroGPT returns an AI percentage but not a corresponding humanization score — so you can't track rewrite progress with a single number. See /humanization-score/ for details.
No. There's no migration path between the tools. You'll start fresh on TextSight.
