Summary
AI Detect is a free, open-source tool that scores writing sentence by sentence for signs associated with AI-generated text. Text inference runs on the user's hardware, and once a model is downloaded and cached, the tool can run offline. Its default DeBERTa-v3-large model download is about 1.7 GB; a 126 MB RoBERTa ONNX option is available for faster triage. The tool flags patterns such as missing contractions, formal verbs, and formal transitions, and offers plain-English rewrite suggestions. It is distributed as a command-line tool, Python package, and MCP server, which can connect with Claude Desktop, Claude Code, or another MCP client. CPU is the default, while CUDA is used automatically when available; a GPU is optional. Sentences shorter than five words are skipped. The maker labels the software beta and advises treating results across a batch as a signal, not an individual sentence verdict. The project is MIT-licensed, and the repository notes that this local tool has no support contract or polished dashboard.
Who it is for
AI Detect is suited to people checking commissioned or unpublished writing locally, especially when reviewing batches of text. It may appeal to command-line and Python users, or people using MCP clients.
