Gramai by Krox Group

Select some text anywhere, in an email, a comment or a post. Right-click it and pick Gramai > Fix grammar. The corrected text replaces your selection right there. If the field can't be edited, you get the result in a small panel with a Copy button. There is nothing to set up. No account, no API key, no model to choose.

What it does

• Fixes grammar, or makes the text professional, friendly or concise
• Translates to the language you choose, from the same menu
• Works in webmail, social networks, note apps, comment boxes and plain text fields, wherever you type
• Undo with one click, or switch the style or language right from the result panel
• Detects the language on its own, or you can pick one

Plans

• Free: 10 actions on every installation. Just install and right-click.
• Basic ($2.99 a month or $24.99 a year): 50 actions and 60,000 characters a day, up to 3,000 characters per action
• Pro ($5.99 a month or $49.99 a year): 150 actions and 200,000 characters a day, up to 8,000 characters per action
• Own key ($4.99 once): use your own API key from the AI provider you already pay, or any OpenAI-compatible endpoint, including a local one. Unlimited actions, billed by your provider.

The 10 free actions include every feature and up to 3,000 characters each, and they don't reset. Basic and Pro keep the no-key setup and raise the daily amounts, which reset at midnight UTC. Own key is a one-time payment for people who prefer to run Gramai on their own provider key.

Privacy

On Free, Basic and Pro your text goes through Gramai's own server to the AI model and is never stored or logged. On Own key it goes straight to the provider you picked. License checks go to Lemon Squeezy.

Known limitation: Google Docs draws its text on a canvas, so it isn't supported.
