About this app

Uptie is an English learning app that automatically creates your own personalized learning materials using AI-based English corrections.
You can use the writing you really want to write, such as diary entries, English emails, and social media posts, as learning material.

■ Solve these problems
・Corrections are the end of it, and revision doesn't continue.
・Memorized expressions don't appear in actual sentences.
・You're too busy to organize study time.

■ What Uptie Can Do
1) Write sentences in Japanese or English (supports Japanese-to-English translation)
2) AI refines your English and suggests study points.
3) Extract phrases from corrections and automatically create study cards.
4) Optimize review timing with spaced repetition (forgetting curve) (automatic difficulty adjustment).
5) Pronunciation practice: Identify areas for improvement with word- and phoneme-level feedback.
6) Hands-free learning: Study while on the go with text-to-speech (TTS) and repeat.

■ Main Features (Keywords: English learning / English correction / English composition / pronunciation)
・Smart Corrections: AI-based English corrections + generating study materials from your writing.
・Phrase Learning: Streamline phrase memorization with spaced repetition.
・Pronunciation Practice: Check your pronunciation by comparing it with the model audio.
Hands-Free Learning: Supports learning in your spare time.
