Description
WriteHuman is an AI humanizer built around a paste-and-rewrite workflow, bundling an AI Humanizer, AI Detector, AI Image Detector, and a Chrome extension in every paid plan. Beyond the consumer web app, WriteHuman offers a REST API and an MCP (Model Context Protocol) server, letting developers call humanization programmatically or connect it directly to AI agents. The product also ships native iOS and Android apps, and every tier includes both humanizer and detector access, with higher plans adding more requests, longer per-request word limits, and priority support.
Key Features
- AI Humanizer: Rewrites AI-generated text with multiple output variations per request, depending on plan.
- AI Detector: Checks text for AI-generation signals, included on every plan including Free.
- AI Image Detector: Detects AI-generated images, included on every plan alongside the text tools.
- Chrome Extension: Humanizes and fixes writing directly inside any browser tab.
- MCP server: Connects WriteHuman’s humanization directly to AI agents and agentic workflows.
- Humanizer API: Word-based REST pricing supporting 40+ languages, with code examples in JavaScript, Python, and cURL.
How It Works
A user pastes AI-generated text into WriteHuman and clicks the humanize button, receiving one or more rewritten variations depending on their plan, with the AI Detector available in the same workspace to check the human score of any text before or after rewriting. The Chrome extension brings the same humanize-and-fix workflow into any tab without switching to the WriteHuman site. Each plan caps the number of monthly humanizer requests and the maximum words per request, scaling up from the Free tier’s 3 requests and 250-word cap to Ultra’s unlimited requests and 3,000-word cap. Developers instead call the REST API directly, or connect WriteHuman’s MCP server so an AI agent can request humanization as part of its own workflow.
Technical Architecture & Overview
- Core Engine: A proprietary humanization model with a separate “Enhanced” quality tier unlocked from Basic upward; Free plan runs on a lower “Basic” quality setting.
- Deployment: Web app, Chrome extension, and native iOS and Android apps.
- API Surface: A REST API with word-based pricing and 40+ language support, plus an MCP server for direct AI agent integration (1,000 MCP calls/month included on Ultra).
- Known Limits: Monthly requests, max words per request, and detection checks all scale by plan; the Free plan is capped at 3 humanizer requests and 250 words per request.
Pros & Cons
| Pros | Cons |
|---|---|
| Every plan, including Free, includes full access to both the AI Humanizer and AI Detector. | The Free plan is capped at just 3 humanizer requests and 250 words per request each month. |
| MCP server support lets AI agents call WriteHuman directly, ahead of most competitors in this category. | Monthly prices ($18-$48) run noticeably higher than annual prices ($12-$36), so annual billing matters for the advertised value. |
| Native iOS and Android apps plus a Chrome extension cover more surfaces than a web-only competitor. | MCP access is limited to Pro and Ultra plans, with Ultra capped at 1,000 calls a month rather than unlimited. |
| The developer API supports 40+ languages with word-based pricing and ready-made code examples. | Third-party testing has reported mixed results against strict detectors like Turnitin on certain content types. |
Pricing
