Pricing & free tier — last checked
How we checked: read directly from the vendor's own pricing page — source
A clean rebrand we had missed: twaingpt.com redirects to verva.com, whose own copy states that TwainGPT is now Verva. The product is continuous - same humanizer, same $8/$20/$40 tiers, same 100+ language support - with an AI detector added alongside it. Our pricing was already correct; the identity was not.
| 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 | Two tools: an AI Humanizer and an AI Detector. The detector is new relative to our previous listing. | Changed since last check |
| Detectors targeted | GPTZero, ZeroGPT, Copyleaks, Quillbot, Turnitin, Writer and Grammarly, per the vendor. | Confirmed |
| Pricing | Three tiers from $8 to $40 per month billed annually - unchanged from what we published. | 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. | Reported, not confirmed |
| 'Industry-leading accuracy' | A vendor marketing claim for the detector. Not repeated on our page. | Reported, not 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
