Overview

WriteHuman aims to make AI-generated writing read more naturally while retaining its original voice and meaning. It accepts text from tools such as ChatGPT, Claude, Gemini, Grok, and DeepSeek, and supports more than 40 languages. Its stated uses span articles, blog posts, marketing copy, emails, landing pages, newsletters, and reports, making it relevant to people adapting drafts for several formats.

That range does not remove the need for editorial review. The company warns that rewrites can change meaning and that detection results can be inaccurate; it does not guarantee a particular score or outcome. If your workflow depends on a reliable detector verdict or a faithful, publish-ready rewrite without human checking, this is not a dependable fit.

Key features

Rewriting and detection

The detector gives each sentence its own AI probability, which can help focus attention on particular parts of a passage. Paid plans provide multiple output variations, giving writers alternatives to compare. Those are useful aids rather than proof of authorship or a guarantee that a revised passage preserves its intent.

Mobile and browser tools

The mobile app combines a humanizer, an AI writing detector, and an AI image detector, with five free uses of each on a rolling 30-day allowance. That is enough to sample each tool, but not a substantial ongoing allowance. The Chrome extension adds grammar and spelling checks, inline fixes, a personal dictionary, site-by-site controls, and humanization from a side panel; it is the more practical option for writers who edit in the browser.

Developer access and security

Developers can use a REST API, while paid plans include MCP access subject to plan limits. The company says submissions use TLS in transit and AES-256 at rest, and are not sold or shared with advertisers. Its terms also allow the service to use its own AI models and third-party models and services, so these protections do not mean processing is limited to WriteHuman's own systems.

Pricing

The free plan costs 0.00 USD per free and allows three humanizer requests per month, up to 250 words per request, one output variation, 10 detection checks, and 10 image scans. It is a small trial allowance, not a practical volume plan.

Annual plan cards show Basic at $12/mo, Pro at $19/mo, and Ultra at $39/mo, billed annually at $144, $228, and $468 respectively. Basic includes 80 requests per month, 600 words per request, two variations, an enhanced model, and AI detection checks. Pro raises that to 200 requests, 1,200 words per request, and three variations, and adds MCP access. Ultra provides unlimited requests, up to 3,000 words per request, five variations, and MCP access with a 1,000-per-month limit. Paid subscription plan cards include priority support.

Monthly plans are also shown: Basic at 20.00 USD per month and Pro at 29.00 USD per month have the same request and word caps as their annual counterparts, with 160 and 400 detection checks per month and 80 and 200 image scans per month respectively. Ultra costs 59.00 USD per month and includes unlimited requests, detection checks, and image scans, with a 3,000-word request limit and five variations. Because the page's comparison table gives different monthly prices—$20/mo, $29/mo, and $59/mo—than the annual plan cards' $12/mo, $19/mo, and $39/mo figures, check the billing term and checkout total before choosing.

API plans are separate: Standard API costs 29.00 USD per month for 125K words per month, up to 2,000 words per call, one output per request, and 40 requests per minute. Premium 400K API costs 69.00 USD per month for 400K words, 4,000 words per call, three outputs per request, and 120 requests per minute. Premium 800K API costs 129.00 USD per month for 800K words, 6,000 words per call, three outputs per request, and 160 requests per minute. Enterprise has custom pricing and dedicated support.

Platforms

WriteHuman is available on web, Android, iOS, and as a browser extension, with API access for integrations. That mix makes it more flexible than a web-only rewriting workflow, though the app's free-use allowance is limited and API quotas vary by plan.

Who it's for

Marketers, freelancers, professionals, content creators, and agencies can use WriteHuman to revise AI-generated drafts across common content formats and check sentences for AI probability. It makes the most sense for people who value multiple access points and can review rewritten text themselves. It is less suitable for anyone who needs guaranteed semantic fidelity, a guaranteed detector score, or a plagiarism checker; WriteHuman does not include plagiarism checking.

Pros and cons

Pros: Supports more than 40 languages and a broad range of writing types, giving multilingual content teams one humanizer for varied drafts.
Pros: Sentence-level detection, mobile image scans, and browser editing tools extend the product beyond a basic text rewriter.
Pros: API and paid-plan MCP access provide routes for developer workflows, with defined word and request limits on API tiers.
Cons: Rewrites can change meaning and detection can be inaccurate, so neither is suitable as an unquestioned final judgment.
Cons: The free humanizer allowance is three requests monthly at 250 words each, which is restrictive for regular use.
Cons: Annual-card and comparison-table prices differ, complicating cost comparisons; confirm the term and total before subscribing.
Cons: No plagiarism checker is included, leaving that task to another tool.

Alternatives

For a broader comparison, browse the AI Text Humanizers list. Choose HumanizeAI.io if an unlimited overall free-word allowance matters more than WriteHuman's mobile, extension, and API mix; it is web-only and limits words per request. StealthWriter is worth considering if you want 10 humanizations and 10 AI scans daily on its free plan, with Android and iOS apps as well as web access. Pick Rephrasy if a lower annual entry price and a Chrome extension are priorities: its Growth plan is 8.25 USD per month, billed yearly, for 100 monthly humanizations of up to 2,000 words each. Humanize AI offers a free 1,500-word monthly allowance with a 300-word check limit, making it an option for smaller web and API workloads.

Humbot, 254labs Ghost Mode Humanizer, Bypass Engine, and Ryne AI are also alternatives to compare.

Verdict

Choose WriteHuman if you want rewriting, sentence-level detection, and browser, mobile, or developer tools in one service, and you are prepared to review the output. Its broad workflow coverage is the clearest reason to pick it; its meaning and detection caveats, tight free quota, and inconsistent price presentation are reasons to look elsewhere when accuracy or transparent budgeting is paramount.
