Our verdict on AI Detect

AI Detect is an open-source AI-text detector for developers and technical teams that want to inspect writing on their own hardware. It scores text sentence by sentence using a DeBERTa-v3-large model, highlights patterns associated with AI-like writing, and offers plain-English rewrite suggestions. Users can provide text or local files, compare two texts, and receive machine-readable JSON output. CPU and CUDA inference support gives the tool a local path for different hardware setups.

The Free plan is the complete published plan: MIT-licensed open-source software with no API key or usage limits. Operation is local after the model download, and the category specifications include file uploads, batch scanning, and basic report exports. That pricing and deployment model fits developers who prefer control over the runtime and want to integrate detection into scripts or internal workflows rather than send content to a hosted service.

AI Detect’s strongest ecosystem fit is its Model Context Protocol server, with integrations for Claude Desktop and Claude Code. It is distributed as a command-line tool, Python package, and MCP server, so it can support developer-oriented pipelines and assistant workflows. The trade-off is that this is a technical, self-hosted product rather than a browser extension or web platform, and the project is described as beta. Choose AI Detect for local, programmable sentence analysis and open-source control; choose an alternative if your priority is a browser-first review experience or a dedicated HTTP API.
