Plans and limits
| Plan | Price | Words per input | Humanizer words per month | Also included | Checked on |
|---|---|---|---|---|---|
| Basic | $8 USD a month, billed annually | Not stated | 8,000 | 100 detector uses, 10 plagiarism scans, 50 generator uses | 9 November 2026 |
| Premium | $20 USD a month, billed annually | Not stated | 30,000 | 500 detector uses, 50 plagiarism scans, 200 generator uses, priority support | 9 November 2026 |
| Ultimate | $40 USD a month, billed annually | Not stated | Unlimited | Unlimited detector, plagiarism and generator uses, priority support | 9 November 2026 |
The entry pool is the number to weigh. At 8,000 words a month, Basic is below every other entry plan in the hub that states a pool: Undetectable AI gives 10,000 for $5.00 a month billed yearly, GPTHuman 25,000 for $8.25 a month billed yearly, Walter Writes AI 30,000 for $8 a month billed yearly and StealthGPT 50,000 for $29.99 monthly, all checked on 8 November 2026. Verva's Premium plan, 30,000 words at $20 a month billed annually, matches Walter's Starter pool at two and a half times the price. What the extra buys is the detector, plagiarism and generator allowances in the table.
The pricing page opens on the annual toggle, marked 20 percent off, so the per-month figures below are annual rates divided by twelve. The monthly toggle prices were not in the page as read on 9 November 2026 and are left out rather than estimated.
The absence of a free tier or trial is the other gap. Eight of the twelve tools in the hub offer a free tier or a no-charge trial, and two more sell a short trial for $1 or $2, checked on 8 November 2026; Verva and HIX Bypass state neither. The protocol's inputs run 350 to 500 words, so any Verva plan accepts them, and the cheapest plan that accepts the input, Basic, is the one the run uses.
What it did to our text
Does TwainGPT (Verva) work?
TwainGPT now trades as Verva, and its Basic plan sells 8,000 humanizer words a month for $8 a month billed annually, read on 9 November 2026. This TwainGPT review covers the product under its new name, on the same fields as every tool in the reviews hub: verdict, best for, main limitation, free tier, cheapest plan and limits, with the same published method to decide where it ranks.
Why does this TwainGPT review say Verva?
Because the product moved. A request to twaingpt.com returns a redirect to verva.com, and the Verva site carries a banner reading "TwainGPT is now Verva" with a link to its announcement post, both read on 9 November 2026. Reviews, forum threads and bookmarks written before the change still use the old name, which is why both names appear here. Plan names on the old site are not recorded in this site's research, so the table below carries Verva's current plans only, and the run will record the product under the name the interface shows on the run date.
The Verva pricing page describes the product in one line, as an advanced and consistent AI humanizer, and lists a "watermark and future proof" feature on every plan without defining it, read on 9 November 2026. The site also sells an AI detector and a plagiarism checker as part of each plan. The vendor publishes no accuracy figure that this review could quote with a source, so none appears here.
The research on paraphrasing is the same for Verva as for any tool in the hub. Weber-Wulff and colleagues tested 14 detection tools and found all of them below 80 percent accuracy, with accuracy falling further on paraphrased and machine-translated text (Weber-Wulff et al. 2023, International Journal for Educational Integrity, read 9 November 2026). Krishna and colleagues found that a paraphrase model dropped DetectGPT's detection rate from 70.3 percent to 4.6 percent at a 1 percent false positive rate (Krishna et al. 2023, arXiv, read 9 November 2026). Paraphrasing lowers detector readings; what a given tool does to meaning while doing so is the unanswered part, and the part the method weights highest.
What does the bundled detector tell you?
Verva's plans include 100 AI detector uses on Basic and 500 on Premium, read on 9 November 2026. A detector sold by the humanizer's own vendor can be a useful preview, but it is not independent evidence. The site's run checks every output on GPTZero, Originality.ai, Copyleaks, Pangram and ZeroGPT. GPTZero states a false positive rate of no more than 1 percent for its document classifier (GPTZero technology page, read 9 November 2026), and each detector's own threshold defines a pass for that detector.
No detector score should be the only evidence in a misconduct case.
What does TwainGPT (Verva) change in your text?
The pricing page names no rewrite modes, so there is no default and strongest pair to describe, and the protocol will run whatever the interface shows on the run date and record the setting in the raw files. The one named feature, "watermark and future proof", appears on every plan without a definition on the page read; the review does not guess at what it means.
| What the vendor states | What the method measures |
|---|---|
| An AI humanizer, an AI detector and a plagiarism checker in one plan | Humanizer output only; the bundled detector is not used as evidence |
| 8,000 humanizer words a month on Basic | Whether a 350 to 500 word input fits, scored under limits and access |
| No per-request cap published | Recorded as not stated until the interface shows one |
| "Watermark and future proof" on every plan | Not defined on the page read; not scored |
| Chrome extension | Noted, not scored |
The reader-side questions are the same as for every tool: claims kept, claims invented, errors introduced per 100 words, and readability change. Those figures appear here once a run is published.
Who should use TwainGPT (Verva)?
Choose Verva if you humanize fewer than 8,000 words a month, want an AI detector and a plagiarism scan under the same login, and do not need to try the tool before paying a year up front.
Look elsewhere if you want a trial or a free tier first: the Walter Writes AI review covers a 300-word trial and a 30,000-word Starter plan at the same $8 a month billed yearly, and the Undetectable AI review covers a 250-word trial and a 10,000-word plan at $5.00 a month billed yearly, both checked on 8 November 2026. Anyone writing for a class should read their institution's AI policy first; a humanizer does not make undisclosed AI use acceptable.
Verva has no head-to-head page yet; the closest plan comparison is Walter Writes AI vs Undetectable AI, and Verva sits with all twelve tools in the ranked list of humanizers.
