LeapMe AI Proofreading Tool is a free web-based service from Liume Inc. that uses AI to automatically correct typos and grammar errors in Japanese and other languages. The AI understands context to produce natural, accurate text rather than just flagging individual errors.

The web tool is immediately usable without login and handles multiple languages including Japanese and English. LeapMe also offers a companion iOS keyboard app powered by ChatGPT-4o and Claude that brings proofreading and text creation features to any app including Gmail, LINE, Instagram, and Facebook Messenger. The keyboard includes tone conversion options (friendly, humorous, business polite) and honorific conversion for adapting text to different contexts.

The combination of a browser-based tool for longer documents and a mobile keyboard for quick messaging gives users flexibility in how they access AI-powered text correction across different devices and workflows.

Free
The web proofreading tool is completely free with no login required. The iOS keyboard app offers basic features for free with additional capabilities available in-app.
