About Grammarbit

A calm, focused place to practise English grammar — free for everyone, from children to grandparents.

Why it exists

Grammar sticks through practice: lots of short, varied exercises with instant explanations. Instead of a fixed list of questions, exercises are generated from hand-written grammar rules and vocabulary, so there are always new ones — and every sentence is natural English.

How it’s built

  • Levels follow the CEFR scale (A1–C2).
  • Mistakes return as reviews using spaced repetition, so they stick.
  • Every exercise works with the keyboard, a mouse or touch, and with screen readers.
  • No accounts and no tracking: your progress stays in your browser.

Accessibility

We aim for WCAG 2.2 AA: high contrast in both themes, adjustable text size, visible focus, full keyboard support, and reduced motion when your device asks for it. If something doesn’t work for you, we want to know.

Support Grammarbit

Grammarbit is built in spare time and will stay free. If it has helped you, you can buy me a coffee on Ko-fi. It pays for hosting and new topics.
