How much does StealthGPT cost?

StealthGPT's pricing page lists Pro at $1 for 3 days, then $29.99 a month, for 50,000 words a month and 1,000 words per request. Max is $49.99 a month after the same trial, and Enterprise is $179.99 a month, billed monthly.

There's a small free tier: up to 100 words in the desktop homepage humanizer, according to StealthGPT's humanizer page . Higher usage starts with the $1 three-day trial.

What is a free StealthGPT alternative?

Our box is free with no account, takes 20 to 1,000 words per run in Casual, Professional or Academic tone, and has a cap of 5 runs a minute and 20 a day per connection. It makes no detector promises.

What does StealthGPT say about Turnitin?

StealthGPT makes detector claims on its pages, and its humanizer page says the third-party ranking it cites does not measure Turnitin. No tool can honestly promise a detector result.

StealthGPT vs ChatGPT Humanizer: the published facts

Reading StealthGPT's plans

The StealthGPT pricing page lists three plans. Keep the monthly allowance and the per-request cap apart; they're different limits.

Plan	Price as listed	Words per month	Words per request
Pro	$1 for 3 days, then $29.99 a month	50,000	1,000
Max	$1 for 3 days, then $49.99 a month	200,000	2,000
Enterprise	$179.99 a month, billed monthly	1,000,000+	10,000+

The pricing page also offers weekly and yearly billing and says yearly saves up to 52.5%. The $1 trial rolls into the monthly price unless you cancel, so put a reminder in your calendar if you try it.

For one ChatGPT draft a week, the Pro allowance of 50,000 words a month is far more than you'll use. For an agency rewriting client copy every day, it may be the right size.

The free tier

StealthGPT's AI humanizer page says you can try up to 100 words free in the desktop homepage humanizer, with advanced tools and higher usage behind the $1 trial. A hundred words is a paragraph. Our box takes up to 1,000 words per free run, so most ChatGPT answers fit in one go, with a cap of 5 runs a minute and 20 a day per connection.

The detector claims, as StealthGPT states them

StealthGPT's pages lead with detectors. The pricing page headline invites you to "Beat AI detectors", and a logo strip names well known detectors under the line "We beat every AI Detector". The humanizer page cites a third-party October 2026 ranking and StealthGPT's own study of three academic passages.

To its credit, the humanizer page also lists the limits of that evidence: it says the ranking it cites does not measure Turnitin, and that its own threshold counts are "not a real-world success-rate estimate". Those are the vendor's statements, and we don't rank on detector results.

Our position stays the same on every page: no rewrite tool can honestly promise how a detector will score your text, and none changes your school's rules on AI use.

Where StealthGPT is ahead

Three models. Super, Standard and Lite, so you can choose a deep rewrite or a light edit.
Document upload. The humanizer page says you can upload .docx, .pdf or .txt files instead of pasting.
Bigger paid requests. Up to 2,000 words per request on Max and 10,000+ on Enterprise, per the pricing page.
Developer access. An API and an MCP server for teams that want humanizing inside their own tools.
Practical editing advice. The humanizer page tells users to check arguments, citations, quotations and numbers after a rewrite, which is good advice for any tool.

Where our box is the simpler choice

Free means free. No trial that rolls into a monthly plan.
Ten times the free run. 1,000 words against the 100 on StealthGPT's free tier.
No account for any tone.
Writing first. The box and the guides focus on how a ChatGPT draft reads, not on detector scores.

The quickest way to judge is your own text. Run your ChatGPT draft through our box first; if you need upload, models or an API after that, StealthGPT's trial is there.

Who should stay with StealthGPT?

Stay with StealthGPT if:

You process whole documents and want to upload files rather than paste.
You want to pick a model per draft.
You need an API or MCP access.
You rewrite tens of thousands of words a month and the per-word cost of a paid plan suits you.
You need language support beyond English; StealthGPT lists 100+ languages in its plan table and 50+ in its stats strip, so check your language on its languages page.

Switching from StealthGPT: what to know

If you're on the $1 trial, the main thing is timing. The StealthGPT pricing page lists the trial at 3 days before Pro moves to $29.99 a month, so cancel before then if you don't plan to stay.

If you're a paying user, check what you'd lose:

Uploads. Our box takes pasted text only. Long papers need splitting into parts of up to 1,000 words, ideally at section breaks.
History. StealthGPT lists history among its plan features. Copy any rewrites you want to keep; our box stores nothing after it returns a rewrite.
Model choice. You'll trade three models for three tones. Professional is the closest match to a light edit; Academic suits essays and lab reports.
API and MCP. We don't offer either. If your workflow depends on them, StealthGPT is the better fit.

Whichever tool you use, StealthGPT's own advice holds: after a rewrite, check the argument, citations, quotations and numbers before you submit.

How we compared the two

Every comparison on the site uses the same fields, filled from the vendor's own pages; we read both on November 8, 2026 and confirmed stealthgpt.ai as the official domain. The full method is on how we test humanizers: three sample drafts (a short essay paragraph, a work email and a product description), checked for meaning kept and readability.

This page weighs published features and limits only.
