## What is WriteFlow?

WriteFlow is a writing app for Japanese-language creative writers. The app's interface and AI assistant are in Japanese.

- Write on Japanese manuscript paper (genkō yōshi), vertically or horizontally
- Consult the AI assistant without leaving your manuscript: brainstorm plot twists, rephrase passages with richer sensory detail, and check typos and notation consistency
- Register your story's synopsis, characters, and world rules so the AI answers consistently with your setting
- Daily quotas calculated backward from your deadline, recorded automatically from how much you wrote
- Focus timer with Live Activities

Premium (monthly auto-renewing subscription): unlimited works, AI assistant (up to 100 requests per month), vertical writing, themes, iCloud backup.

Payment is charged to your Apple ID. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel in your App Store account settings.
