## What is Hachimo?

Do your English lessons with ChatGPT or Claude keep starting from zero?

Hachimo is the learning memory for your AI English practice. It keeps the mistakes, corrections, and words you choose to save, brings them back before you forget, and turns your history into the next focused 5–20 minute plan.

YOUR AI TEACHES. HACHIMO REMEMBERS.
Keep conversations, corrections, and drills in ChatGPT or Claude, the tools you already use. Hachimo organizes what came out of each lesson so your next session can continue from where the last one ended.

ONE CLEAR NEXT STEP
Hachimo prioritizes due reviews, lessons in progress, and the next activity. Adjust today’s plan to the five, ten, fifteen, or twenty minutes you actually have.

REVIEW YOUR OWN MISTAKES
Corrections, vocabulary, and useful expressions saved through the AI connection become a searchable Memory. Spaced review brings them back at the right time.

PROGRESS BASED ON REAL PRACTICE
See completed lessons, saved Memory, learning-stage items, consistency, and recent lesson evidence based on what you actually did.

WIDGET AND NOTIFICATIONS
The "Hachimo Today" widget on the Home Screen and Lock Screen shows your streak, today's lesson, and review cards at a glance. When your AI delivers a new lesson, Hachimo lets you know (if notifications are on).

Hachimo is for you if you:
• practice speaking or writing with ChatGPT or Claude
• want to stop repeating the same mistakes
• are tired of copying everything into a separate flashcard app
• need a useful routine that fits into a few minutes

HACHIMO PRO IS REQUIRED
Using the app and connecting ChatGPT or Claude requires Hachimo Pro (monthly or yearly). The yearly plan starts with a free trial for eligible new subscribers; after the trial, the yearly price is charged. The trial length, price, and terms are shown on the purchase screen.

If you purchase a subscription, payment is charged to your Apple Account. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel your subscription in your App Store account settings.
