Grammate

Grammate is a grammar checker for Windows that works inside the apps where text is already being written. It is built for people who want corrections in the same workflow, with review before replacement and an option to replace text only when the change matches their intent.

The product’s core workflow centers on selecting text, reviewing suggested edits in a focused panel, and then sending the rewrite back into the original app. It also offers an instant replace flow for quicker correction. The site says this approach keeps grammar help next to the selected text, avoids copy-paste detours, and keeps edits visible before replacement. Grammate is described as working across Word, Outlook, Chrome, Slack, Telegram, Teams, Discord, Obsidian, LibreOffice, Notion, Notepad, and more, with support for “almost any Windows app” that follows the Windows text-selection workflow.

Two operating modes are named. Local mode keeps text on the user’s PC, runs AI on the user’s own Windows machine, works offline after local model setup, and is described as having no correction cap once the local AI is installed. Cloud mode sends text to a hosted AI service instead of the PC, starts faster, and is described as lighter on the device. The pricing section says the free plan includes unlimited Local Mode and up to 20 cloud corrections per day. Paid plans raise the daily cloud limit, with Starter offering up to 150 cloud corrections per day and Pro offering up to 400 per day. Monthly and yearly billing are listed, and the yearly option is marked as saving 25%.

The page repeatedly frames Grammate as a Windows-focused tool for writing, email, chat, short drafts, and long-form work, while emphasizing user control over the final text.
