What is WriteHuman?
Reviewed WriteHuman's site, docs, and pricing as of 2026-10-26. Not deployed yet. WriteHuman rewrites AI-generated text into human-cadence prose, bundling a per-sentence AI detector, image detector, Chrome extension, REST API, and MCP access. The free tier gives 3 requests/mo at 250 words; paid plans start at $12/mo annual, with unlimited requests only at Ultra ($39/mo annual).
Key Features
AI Humanizer
Paste text from ChatGPT, Claude, Gemini, Grok, or DeepSeek and rewrite it in 40+ languages, with Standard and Enhanced modes and up to 5 output variations per request.
Per-sentence AI Detector
Every sentence gets its own AI probability score — the site frames under 40% as reads human and over 60% as flagged — with 160, 400, or unlimited detection checks per month by tier.
API and MCP access
REST endpoint POST /v1/humanize with word-based pricing and code samples in JavaScript, Python, and cURL; MCP connects the humanizer to AI agents, capped at 1,000 calls/mo even on Ultra.
Chrome Extension
Humanize and fix writing in any tab, per the Chrome Web Store listing linked from the site, alongside an AI image detector and word counter.
Pros & Cons
What works
- 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
Watch out for
- 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
- Replies to only 20% of negative Trustpilot reviews, and no G2 listing exists for a second signal
Who is it for?
Freelance writers and ghostwriters
Client-side AI checks make the per-sentence detector and multiple output variations the core value; Basic's 80 requests/mo covers steady freelance volume at $12/mo annual.
SEO and marketing content teams
Pro's 200 requests/mo at $19/mo annual fits regular publishing, but the 1,200-word request cap means long-form pieces get split into chunks.
Developers and agent builders
REST API and MCP are first-class, but API pricing is word-based and separate from plan quotas, and MCP caps at 1,000 calls/mo even on Ultra.
Students
The product is explicitly detector-evasion oriented; usefulness depends entirely on institutional policy, and Trustpilot shows academic-adjacent refund disputes.
Reviewed WriteHuman's site and pricing page on 2026-10-26. Not deployed yet — this draft is research-only, and every number below comes from writehuman.ai on that date.
WriteHuman is a premium AI humanizer: paste machine-generated text, get back prose pitched at human cadence. The site calls itself "the premium AI humanizer for serious writing," and the lineup covers the AI Humanizer, a built-in AI detector that scores every sentence, an AI image detector, a Chrome extension, a REST API (POST /v1/humanize, word-based pricing, 40+ languages), and MCP access for AI agents. WriteHuman is rewriter-first. The detector, image scanner, and MCP hooks exist to support the humanizer, not the other way around.
Plans and true cost
The free tier is real but tiny: 3 humanizer requests a month, 250 words each. Paid plans halve on annual billing — marketed as "4 months free" — and the year is charged upfront:
| Plan | Annual | Monthly | Requests/mo | Words/request |
|---|---|---|---|---|
| Basic | $12/mo ($144/yr) | $20/mo | 80 | 600 |
| Pro | $19/mo ($228/yr) | $29/mo | 200 | 1,200 |
| Ultra | $39/mo ($468/yr) | $59/mo | Unlimited | 3,000 |
The "save" figures ($96/$120/$240 a year) are simply the monthly-vs-annual delta. Detection checks and image scans follow the same shape (160/400/unlimited and 80/200/unlimited per month), and MCP is capped at 1,000 calls/mo even on Ultra.
The Catch
WriteHuman's own banner concedes the arms race: "Enhanced model updated for GPTZero and Pangram." When a humanizer ships updates that target specific detectors, every fix has a shelf life — detectors update back. October 2026 Trustpilot reviews show the pattern live: users report WriteHuman output flagged as 100% AI-written by Pangram after the update claiming Pangram coverage, and refund requests denied even when filed within a day of purchase. Buying this to pass one specific detector means buying a subscription to a race with no finish line. Second catch: quota math. "Unlimited" exists only at Ultra, and every tier caps words per request (600/1,200/3,000), so a 5,000-word post burns multiple requests on Basic.
Who should pay
Freelance writers and content teams whose clients run AI checks get the clearest value — the per-sentence detector turns revision into targeted edits instead of reroll roulette. Developers get the API and MCP, but API pricing is word-based and billed separately from these plans. Students should weigh institutional policy first; the tool is built around evasion, and that trade is theirs to make, not ours to bless. Detection is probabilistic and humanization is temporary — price both in.
