Pricing & free tier — last checked
How we checked: read directly from the vendor's own pricing page — source
Re-read 25 September 2026. The rebrand, detector list and user claim are unchanged. What we corrected was our own pricing copy: $8, $20 and $40 are the annual-billed monthly prices, not monthly prices with a further 20% off for paying yearly.
| What | What we found | Status |
|---|---|---|
| Rebrand | Verva's site states 'TwainGPT is now Verva'. twaingpt.com 301s to verva.com. Listing name, displayName and URL updated. | Changed since last check |
| Products | Three: an AI Humanizer, an AI Detector and a Chrome extension. The extension is new since our 6 September check. | Changed since last check |
| Detectors targeted | GPTZero, ZeroGPT, Copyleaks, Quillbot, Turnitin, Writer and Grammarly, per the vendor. | Confirmed |
| Pricing | Basic $8, Premium $20 and Ultimate $40 per month, each labelled 'billed annually'; the page's Monthly/Annually switch marks annual billing as -20%. Basic includes 8,000 humanizer words, 100 AI detector uses and 50 generator uses; Premium 30,000 words, 500 detector uses and 200 generator uses; Ultimate is unlimited on all three.Our listing presented $8 as the monthly price and then took a further ~20% off for annual billing, which double-counted the discount. Corrected on 25 September 2026. The default view does not show monthly prices, so we quote none. | Confirmed |
| User count | Verva claims 2.8 million users; we previously published 2.1 million. Both are vendor figures. Now attributed to the vendor rather than asserted in our own voice. | Vendor's own statement |
| 'Industry-leading accuracy' | A vendor marketing claim for the detector. Not repeated on our page. | Vendor's own statement |
| Free plan | Verva's own FAQ: 'Yes, Verva offers a free plan with access to core features at no cost.' Neither the FAQ nor the pricing page states its limits.We had published 'daily word limits' and 'no credit card required'. Neither appears on either page, so both were removed rather than guessed at. | Confirmed |
Editor verification notes
- Surfaced by SEO/scripts/stale-url-sweep.mjs, which checks every outbound URL for redirects. A redirect is a lead, not a verdict - each of these was followed to its destination and read before anything was changed.
- The editorReview's central caveat is unchanged and still correct: no humanizer can guarantee a result, detectors update constantly, and academic submissions are scrutinised far more strictly than marketing copy.
- This is desk research against the vendor site read on the stated date, not a first-party account test. Prices are the figures shown to a logged-out visitor and may differ by region.
Checked by the TheToolsVerse Verification Desk — by reading the vendor's own published pages, not by testing the product in an account. Verva (formerly TwainGPT) can change prices at any time without notice. The date above is the last time we looked; if it looks old, treat every figure here as unconfirmed and check Verva (formerly TwainGPT) directly before paying.

Official ReviewReviewed by Sohail Akhtar
Lead Editor & Founder
Pros
What we like
- TwainGPT's support for over 100 languages with grammar-aware humanization addresses a gap that most competing AI humanizers do not fill, making it one of the more practical options for non-English content workflows
- Processing completes in 10–20 seconds without watermarks on output, which fits naturally into editing pipelines where speed and clean output matter more than deep structural rewriting
- The tiered pricing model — starting at $8 per month for 8,000 words — provides accessible entry points for individual creators, with the unlimited Ultimate plan covering high-volume agency or professional use at $40 per month
Cons
Limitations
- Bypass effectiveness is not guaranteed and varies significantly by detector version, content type, and institutional settings — academic essays consistently produce less reliable results than blog posts or marketing copy
- TwainGPT only rewrites existing AI-generated text and does not generate original content, which means it is a post-processing step rather than a standalone writing tool and depends entirely on the quality of the input
