Pick your surface.
Offbeat is one engine behind four doors. Each guide takes you from zero to a verified rewrite, with the honest limits stated where they apply.
The web tool
Paste, check, humanize, verify. Where the findings come from, what the two modes do, and what every button on the scorecard means.
Your own key
Two minutes to unlimited rewrites under your own data terms. Google AI keys or any OpenAI-compatible endpoint, kept in your browser session only.
The MCP server
Give Claude Code, Codex, or OpenCode the analyzer as native tools. Your editor's model does the rewriting; every analysis is scored by the hosted premium engine.
The CLI
Scan prose from the terminal, gate CI on writing quality, and run the closed loop against the model you already have.
