26Keys

You've corrected the same mistakes for years. The tools fixed your text every time. They never improved your English. 26Keys was built to end that loop.

How it works - Bring in the message or email you're already writing. - Get it proofread without losing your voice. No rewrites, no AI-generated text. - 26Keys learns your mistake patterns from your very first message. - Your patterns become your daily practice, resurfaced at the right time with smart spaced repetition. - You learn why it's wrong, not just what. And you break the pattern for good.

Your writing improves. Speaking follows.

What you'll notice - Practice always matches your level. Never too easy, never too hard. - New vocabulary comes from your own writing. Words you'll actually use. - Progress you can measure: your error patterns fade week over week. No streaks, no badges. - Short games, writing ideas, focus mode, and detailed stats when you want them.
