The headline differences. Detailed analysis below.
- Starting price
- $18/mo Basic
- Standout
- Scored 76.69 in the August 2026 HumanizerBench cycle — first of twelve humanizers — plus a built-in detector, multi-language support, and a $48/mo unlimited plan

- Daily caps on every tier, even at $100/mo Pro
Bottom line: WriteHuman is the better pick for most writers. It finished first of twelve humanizers in the August 2026 HumanizerBench cycle, 76.69 to Stealth Writer's 69.83, and it is cheaper at the entry tier, uncapped at the top, and free to try without an account.
Benchmark results
WriteHuman finished first overall in August
HumanizerBench is a public monthly benchmark of AI humanizers. It pays for every tool, runs each one by hand on the same prompts, and publishes its inputs, outputs, and detector scores so the results can be checked. The August 2026 cycle ran 396 tests across twelve humanizers and five detectors.
Stealth Writer did well, placing third of twelve. WriteHuman finished first, scoring 76.69 to Stealth Writer's 69.83 on the overall composite, with a higher AI-detector pass rate across the whole test set (89.1% versus 79.7%) and a cleaner writing-quality (readability) rating (57.8% versus 43.7%). It is a narrower margin than most of these matchups, and the module above shows only the cells WriteHuman wins; Stealth Writer is genuinely competitive on several others.

Detector results
GPTZero is where the gap opens up
The benchmark scores every tool against five AI detectors. On GPTZero, WriteHuman's output read as human-written 88.4% of the time in the August 2026 cycle, while Stealth Writer's read as human 30.8% of the time. GPTZero is one of the detectors readers and platforms reach for first, so that split matters if it sits anywhere in your workflow.
Originality.ai ran the same direction, 66.5% for WriteHuman against 43.7% for Stealth Writer. Stealth Writer does hold up on other detectors the benchmark runs, so this is not a clean sweep in either direction. But if GPTZero or Originality.ai is the check you actually have to clear, the difference is hard to ignore. WriteHuman's built-in AI detector sits in the same view as the humanizer, so you can see roughly where a passage will land before you publish it.

Consistency
Steadier from one content type to the next
A humanizer is only as useful as its weakest content type. In the August 2026 cycle WriteHuman scored 80.8% on consistency across writing categories against Stealth Writer's 73.5%, and led on blog posts (95.4% versus 92.9%), marketing copy (97.1% versus 88.9%), and discussion posts (99.9% versus 63.0%).
Discussion posts are the widest of those splits, and they are exactly the kind of short, conversational text people paste in without thinking twice about it. Steadiness across formats is what lets you trust a tool on whatever you paste in next, instead of getting a strong result on one kind of writing and a weak one on the next.

Pricing
Cheaper at entry, uncapped at the top
Stealth Writer starts at $20/mo for the Starter plan and gates everything by daily quotas. 50 humanizations a day on Starter, 150 on Plus ($50/mo), and 350 on Pro ($100/mo). If you hit the cap, you wait until tomorrow.
WriteHuman starts at $18/mo for Basic, $27/mo for Pro, and $48/mo for Ultra. Ultra is genuinely unlimited, with no daily counter to plan your work around.

Daily limits
Daily caps on every paid tier, all the way up the lineup
Every Stealth Writer paid plan is rate-limited by daily humanization quotas. Starter is 50/day, Plus is 150/day, and Pro at $100/mo is 350/day. There is no truly unlimited plan.
For an agency batching client work, or a content team running iteration cycles on a single article, those caps are punishing. WriteHuman's Ultra at $48/mo has no daily cap, so you can iterate as much as you need without watching a counter.

Quality
Cleaner rewrites, less editing after the fact
Independent reviewers report that Stealth Writer's output drifts on longer passages: broken sentences and clumsy edits on aggressive rewrites. One published review put it plainly, calling the output "riddled with grammatical and syntactically inaccurate content" at times. The rewriter also tends to over-paraphrase, swapping out terms readers expect to see.
The August 2026 HumanizerBench cycle rates that dimension too, and WriteHuman came out ahead on writing quality, 57.8% to Stealth Writer's 43.7%. WriteHuman is tuned to keep the grammar clean and your vocabulary intact, then humanize around it, so the output reads as writing rather than a synonym-shuffle.

What real Stealth Writer users are saying
Quotes pulled from public reviews on Reddit, Trustpilot, G2, and Product Hunt.
“Daily limits are the biggest pain. Even on Pro at $100/mo, you can hit the cap mid-day if you are batching client work.”
“The quality of the output makes it unusable at times, since it is riddled with grammatical and syntactically inaccurate content.”
“You can't even see the pricing without signing up, which feels like a red flag before you've even tried the product.”
