You want local spell checking and grammar without sending every keystroke to the cloud. This plugs into AI assistants like Claude Desktop, ChatGPT, and Cursor to give you offline proofreading, which is clutch if you're working with sensitive content or just want to keep things fast and private. The BYOK (bring your own key) grammar setup means you control which grammar service you use instead of being locked into a vendor. Reach for this when you need writing assistance that stays on your machine, or when you're dealing with confidential documents where you can't justify external API calls for basic spelling and grammar checks.
