WriteHuman

WriteHuman rewrites AI-generated text to read more naturally while aiming to retain its original meaning and voice. The site says it accepts writing from ChatGPT, Claude, Gemini, Grok, DeepSeek and other AI writing tools, and supports more than 40 languages. Listed writing uses include articles, blog posts, marketing copy, emails, landing pages, newsletters and reports. Its AI detector assigns an AI probability to each sentence. The mobile app includes a humanizer, writing detector and image detector, with five free uses of each on a rolling 30-day allowance. The Chrome extension offers grammar and spelling checks, inline fixes, a personal dictionary, site-by-site controls and humanization from a side panel. Developers can use a REST API; MCP access is listed on paid plans subject to plan limits. A free plan is available, with paid plans listed from $12/mo. The pricing page's plan cards and comparison table show different monthly prices. WriteHuman says submissions are encrypted in transit and at rest and not sold or shared with advertisers. Its terms warn that outputs and detection results can be inaccurate or alter meaning.

WriteHuman combines rewriting with detection tools across mobile, web, extension and API offerings. Its plan limits, differing monthly price displays and stated accuracy caveats are important to weigh before choosing a plan.

WriteHuman may suit content creators, marketers, freelancers, professionals and agencies who want rewriting or sentence-level AI detection. Its browser extension and developer API also address users who want tools beyond the web interface.

WriteHuman is a text humanizer with AI detection and image scanning tools for creators who work across mobile, web, browser extensions, or an API. Its mix of tools and generous paid quotas may suit frequent users, but conflicting monthly price displays and explicit accuracy caveats make it a poor choice when a guaranteed detector result or exact rewrite is essential.

Overview

WriteHuman rewrites text generated by tools such as ChatGPT, Claude, Gemini, Grok, and DeepSeek, aiming to make it read more naturally without losing its original voice or meaning. It supports more than 40 languages and use cases including articles, blog posts, marketing copy, emails, landing pages, newsletters, and reports. That range makes it useful for people adapting AI drafts for multiple formats, though the company's terms warn that a rewrite can change meaning.

The built-in detector assigns an AI probability to each sentence, offering a more granular view than a single overall score. It is still an estimate: WriteHuman says detection results can be inaccurate and does not guarantee particular scores or outcomes. Anyone who must meet a specific detector threshold should not rely on it as the deciding check.

Key features

Rewriting and mobile detection

Paid humanizer plans provide two to five output variations, depending on tier, so writers can compare alternatives rather than accept a single rewrite. The mobile app bundles a humanizer, text detector, and image detector, with five free uses of each per rolling 30 days. Those allowances are useful for occasional checks, but too small for routine work without a paid plan.

Chrome extension and developer access

The Chrome extension adds grammar and spelling checks, inline fixes, a personal dictionary, site-by-site controls, and a side-panel humanizer. It is a practical fit for people who want these tools while working in the browser, although it does not change the limits or accuracy caveats of the underlying service.

Developers can use a REST API, and paid plans include MCP access subject to plan limits. API plans specify monthly word quotas, maximum words per call, output counts, and request rates, making them more suitable for defined workloads than casual individual use. Enterprise offers dedicated support. WriteHuman says submissions are encrypted in transit with TLS and at rest with AES-256 and are not sold or shared with advertisers; its terms also allow use of its own models and third-party providers.

Pricing

The free plan costs nothing and includes three humanizer requests per month, 250 words per request, one output variation, 10 detection checks, and 10 image scans. It is a useful way to try the tools, but the request and word caps rule it out for regular drafting.

Annual-billing cards show Basic at $12/mo, Pro at $19/mo, and Ultra at $39/mo, with yearly totals of $144, $228, and $468 respectively. The comparison table instead shows monthly prices of $20/mo, $29/mo, and $59/mo for those tiers. Because those displays conflict, confirm the billing price before subscribing.

• Basic: 80 requests per month, 600 words per request, two variations, an enhanced model, and AI detection checks on the annual card; the monthly comparison adds 160 detection checks and 80 image scans. Its quotas suit moderate use, but the monthly price is substantially higher than the annual-card figure.
• Pro: 200 requests per month, 1,200 words per request, three variations, an enhanced model, and MCP access on the annual card; the monthly comparison specifies 400 detection checks and 200 image scans. This fits heavier individual use or a developer who needs MCP, but still imposes a request ceiling.
• Ultra: unlimited requests, 3,000 words per request, five variations, and MCP access capped at 1,000 per month on the annual card. The monthly comparison instead specifies unlimited detection checks and image scans. Its higher price is most defensible for frequent rewriting, but the per-request word cap remains.

API users have separate monthly plans: Standard API costs $29 a month for 125K words, 2,000 words per call, one output per request, and 40 requests per minute. Premium 400K costs $69 a month for 400K words, 4,000 words per call, three outputs, and 120 requests per minute; Premium 800K costs $129 a month for 800K words, 6,000 words per call, three outputs, and 160 requests per minute. These tiers are clearer fits for production volume than consumer subscriptions. Priority support is listed on paid subscription cards; dedicated support is offered for Enterprise.

Platforms

WriteHuman is available on Android, iOS, web, and Chrome extension, with API access for developers. That breadth helps users move between standalone writing, browser work, and integrations, though the product's limits and reliability caveats apply across those uses.

Who it's for

Marketers, freelancers, professionals, content creators, and agencies who regularly revise AI-generated material are the clearest fit. The free tier suits occasional experimentation; Basic or Pro makes more sense for recurring drafting, while Ultra is aimed at users who need high request volume. Developers should compare the API quotas and call limits against their expected workload. If fidelity to the source meaning or a guaranteed detection score is non-negotiable, look elsewhere.

Pros and cons

• Pro: Support for more than 40 languages and a broad range of writing formats accommodates varied content workflows.
• Pro: Sentence-level detection probabilities, image scanning on mobile, and browser editing tools bring several checks into one product family.
• Pro: Multiple output variations and API tiers with stated quotas give frequent writers and developers options matched to different workloads.
• Con: The annual-card and monthly comparison prices conflict, making the actual subscription cost less straightforward to assess.
• Con: Free usage is tightly capped, and paid request limits still constrain Basic and Pro users.
• Con: The company warns that rewrites may shift meaning and detector results may be inaccurate, with no guaranteed score or outcome.

Alternatives

AI Text Humanizers is a useful place to compare more tools in this category. Choose StealthWriter instead if its free allowance of 10 humanizations and 10 AI scans per day, with up to 1,000 words per input, better suits frequent trial use. Rephrasy is worth considering for a lower annual-billed Growth plan at $8.25 a month, which includes 100 monthly humanizations, inputs up to 2,000 words, a Chrome extension, and one custom writing style.

Walter Writes AI is another alternative. Humanize AI may suit someone seeking a free web and API option with a 1,500-word monthly allowance and 300 words per check. StealthGPT is also an option. 254labs Ghost Mode Humanizer offers a free web plan with 800 words per month, four writing modes, Ghost Mode, and an unlimited AI detector. Bypass Engine is another alternative. HumanizeAI.io is also worth comparing.

Verdict

Choose WriteHuman if you want rewriting, sentence-level detection, mobile image scans, and browser or API tools in one broad offering. Its range and high-volume tiers are compelling for recurring workflows, but the price discrepancy needs checking and neither rewrites nor detector scores are guaranteed. For occasional use, start with the capped free plan; for work where meaning must remain exact or a specific detector result is required, choose a different approach.
