Proofkey is a Grammarly-style Chrome writing assistant that runs using a user's own LLM API key, or Chrome's built-in AI model with no key at all, with no backend, account or telemetry involved. It's built for people who want grammar and style checking without a recurring subscription or their writing passing through a third-party server.
