The record

Purpose: AI Detect is an open-source tool that scores writing sentence by sentence for likely AI-generated text.
Models: Its default model is a 304-million-parameter DeBERTa-v3-large model, with a 126 MB RoBERTa ONNX option for faster triage.
Diagnostics: It flags writing patterns such as missing contractions, formal verbs, and formal transitions, and provides plain-English rewrite suggestions.
Interfaces: It is distributed as a command-line tool, Python package, and MCP server.
Integrations: The MCP server can be used with Claude Desktop, Claude Code, or another MCP client.
Privacy: Text inference runs on the user's hardware; the repository says the only network call is the initial model download.
Offline use: After downloading and caching the model, it runs offline.
Hardware: A GPU is optional: the default is CPU, with CUDA used automatically when available.
Storage: The default model download is about 1.7 GB, while the light model download is about 126 MB.
Input limit: Sentences shorter than five words are skipped rather than scored.
Caveat: The maker describes the software as beta and recommends treating its scores as a signal across a batch rather than a verdict on an individual sentence.
License: The project is MIT-licensed.
Audience: The maker positions it for people checking commissioned or unpublished copy locally, including users handling batches of writing.
Support: The repository says users give up a support contract and polished dashboard when choosing this local tool.
Price from: Free
