The Problem
You can write it. But you can't say it.
You write well, but freeze when speaking
You have the writing skills — but words don't come out when you need to speak.
Textbook phrases don't feel like yours
You can recite examples, but struggle to say what you actually want to say.
You practice but keep forgetting
Without a structured review system, nothing sticks.
Shunsaku solves all three at once.

FAQ
Frequently Asked Questions
Everything you need to know before getting started.
Can I use Shunsaku without DRAWER?
Absolutely. You can start practicing right away with courses and topics — no DRAWER required. The DRAWER integration is a bonus that turns your own journal entries into practice prompts.
Is it okay if my English isn't great?
Yes. Shunsaku's AI evaluates whether your meaning comes across, not whether your grammar is perfect. Speaking out loud — even imperfectly — is how you build the habit.
Does it matter if I skip days?
Not at all. The SM-2 algorithm calculates the optimal review timing automatically, so even irregular practice leads to solid retention.
When does the free trial start?
The 3-day trial begins on the day you create your account. All features are available, no credit card required.
How do I cancel?
If you subscribed via web, you can cancel from the subscription management page. For in-app purchases, cancel through the App Store (iPhone Settings → Apple ID → Subscriptions). No charge if you cancel during the free trial.
How is Shunsaku different from LUNA?
LUNA is a conversational AI partner — you chat with it in English. Shunsaku is a speaking trainer — it drills you on instant English production. LUNA is your speaking partner; Shunsaku is your trainer. They work great together.
