## What it does

Signs of AI Writing highlights patterns such as repeated vocabulary, rhetorical habits, and uniform sentence rhythm, then suggests a revision for each finding. Its originality checker compares documents for shared passages, including paraphrases across languages. The results are evidence for a person to assess, not an automated verdict.

The MCP server is available as the `SignsOfAI.Mcp` package. The wider toolkit supports English and Spanish analysis. Its main checks run locally in the browser, while optional paraphrase checking and perplexity measurement can send text to a server when enabled. Perplexity measurement runs locally in the desktop app. Check those settings before enabling features that transmit text.

## Requirements
- Environment variables: `SIGNSOFAI_API_ENDPOINT` — keys and tokens: ask the human for the values, never commit them or put them in shared files.
