WriteHuman
Best for Writers and small teams who humanize daily and want per-sentence fix targeting, multiple output variations to choose from, and Chrome extension/API/MCP access — $12/mo annual for 80 requests.
For daily professional humanizing — blog drafts, marketing copy, anything with a repeat volume — WriteHuman's fix-the-flagged-lines loop and output variations save enough re-work to justify $12/mo over $8.25/mo. For budget-first users processing under 25,000 words a month in blog-length chunks, GPTHuman delivers the same core loop cheaper, with an API at a price point that's rare. Whichever you pick, buy monthly for the first quarter: both vendors' documented refund behavior makes annual prepayment a one-way door, and both sell a product whose effectiveness decays when detectors update.

Side-by-side deep dive
What it does best
- Built-in AI detector scores every sentence, so revisions target flagged lines instead of full rewrites
- Two to five output variations per request let you pick a version instead of re-spending requests
- Unusual breadth at this price: Chrome extension, REST API, MCP, and 40+ languages alongside the web humanizer
- Genuine free tier (3 requests/mo, 250 words each) to test output quality before paying
The catch
- Detector evasion is temporary by design — the site's own banner advertises a model 'updated for GPTZero and Pangram', and Oct 2026 reviews report Pangram still flagging output as 100% AI
- Trustpilot reviewers report refund requests denied even within 24 hours of purchase, and the pricing page's refund answer is not published in plain view
- 'Unlimited' requests exist only on Ultra ($39/mo annual); every tier caps words per request at 600, 1,200, or 3,000
What it does best
- Low paid entry for the category: $8.25/mo billed annually ($99/year) for 25,000 words/month, with Shield Guard and watermark removal included from the first paid tier.
- The free trial needs no credit card and still includes watermark removal, 50+ languages, the Human Content Generator, and limited AI-detector use — enough to judge output quality before paying.
- Detector and rewriter live in one loop: run the built-in AI detector and re-humanize instantly until the text reads 100% human, instead of juggling separate tools.
- Developer API with claimed 99.9% uptime, sub-second responses, and a no-content-storage policy — production plumbing unusual at this price point.
The catch
- The $26/mo 'Unlimited' plan carries its own footnote — '*Unlimited subject to abuse guardrails' — an undisclosed, vendor-controlled cap on the headline promise.
- Per-output ceilings of 300/1,000/1,500/2,500 words by tier force long documents through multiple runs, burning the monthly quota faster.
- Young product with a thin review base: Trustpilot 3.9/5 from just 16 reviews (profile claimed Nov 2025, no replies to negative reviews) and a G2 profile with zero reviews at capture.

Final verdict
Our pick: WriteHuman
For daily professional humanizing — blog drafts, marketing copy, anything with a repeat volume — WriteHuman's fix-the-flagged-lines loop and output variations save enough re-work to justify $12/mo over $8.25/mo. For budget-first users processing under 25,000 words a month in blog-length chunks, GPTHuman delivers the same core loop cheaper, with an API at a price point that's rare.

Method
Researched from both vendors' pricing pages, pricing FAQs, and review profiles, verified 2026-10-26. We have not run a paid scan battery — every pass-rate statement in this comparison traces to a vendor page or a dated user report, and we label which is which.
Quick verdict
A working writer who humanizes every day should pay for WriteHuman: the per-sentence detector means you fix flagged lines instead of re-rolling documents, 2–5 variations per request turn quota into choices, and the extension/API/MCP plumbing fits a real workflow. A solo publisher watching every dollar gets the same core loop from GPTHuman at $8.25/mo annual — 25,000 words, Shield Guard, watermark removal, even an API — provided documents fit under 1,000 words per run and the prepay risk is understood.
The catch on each side
WriteHuman's catch is the decay plus the exit. The site itself advertises a model 'updated for GPTZero and Pangram' — the vendor confirming that evasion is versioned and temporary — and October 2026 reviews report Pangram still flagging output as 100% AI. Refund requests denied within 24 hours of purchase appear on Trustpilot, the vendor replies to 20% of negative reviews, and there's no G2 page for a second signal. The 'unlimited' tier also isn't unlimited in practice: 3,000 words per output on Ultra.
GPTHuman's catch is the asterisk and the caps. The $26/mo 'Unlimited' plan is footnoted 'subject to abuse guardrails' — an undisclosed, vendor-controlled ceiling on the headline promise. Output caps (1,000 words on Starter) force long documents through multiple runs that burn the monthly quota. And the most instructive review on record combines both failure modes: humanized output that still scored 99% AI, and a refused refund on an unused annual subscription.
When to use both
Unusually for a comparison, they're not exclusive. WriteHuman's free tier (3 requests/month) and GPTHuman's free trial (300 words) cost nothing, so the rational move is running the same draft through both — pick whichever output needs less hand-repair, and re-check the winner against a live detector the day you publish, because a pass from last week is not a pass today.
The one-liner
WriteHuman sells a fix-loop for people who publish daily; GPTHuman sells word volume for people who pay monthly-by-nature — and both prices buy a lease, not a permanent pass.
