Self Service
Conversation spoken out loud
Your service doesn’t feel disconnected. Memorized words become diary entries, then phone conversation lines—and mistakes in your diary turn into review again. Let AI polish what I write and say—examples, grammar, journal entries, and calls.
Products by Service
As much as you need, as your role requires
Words & Grammar — Learners, Teachers, Parents (3 products)
Three subscriptions tailored to your role. Teacher Class Code basic features and parent child sign-up & payment management are free.
Diary & Self-Call — Single Learner
It’s a self-recording and speaking-focused service, so one learner subscription is all you need.
No quick sell
Use just one service for life for a truly complete learning experience. We don’t force you to bundle four.
Multiple Subscriptions
The more you have, the lower each service value gets
Other options besides subscription
Subscription isn’t the only answer
Individual Payment
Only pay monthly for the features you need instead of a subscription. If the total exceeds the subscription price, we’ll let you know first that “a subscription is cheaper.”
Learning Habit Bootstrapping
A 12-week graduation program that starts with pocket money and ends without it (vocabulary & grammar). Includes a Premium subscription for your child + a parent coach. If you graduate early, choose one: credits, subscription replacement, cash, or a charitable donation.
Follow along
A relationship-based product that lets you follow the learning of your parent, partner, or friends. It starts only after the other person accepts, and progress is independent for each of you.
Ads and Rewards
Ad revenue isn’t something the company has
Ads that don’t interrupt learning
Ads appear only before and after lessons. They won’t interrupt you while you’re learning, and the gem-charging ads are something you choose yourself when you want.
Refund in full to learners
Free ad revenue doesn’t belong to the company—it goes into the SAUNA Reward Pool and is paid out to learners who keep showing up and sweating it out.
Habit Level
Like a decision growing, your consistency becomes clearer.
Bronze
Silver
Gold
Platinum
Sapphire
Ruby
DiamondThis is a level you can’t publish via external payments. Only learning that’s actually completed changes the density of your decisions.
Reward Graphics
Redemption is remembered not just as numbers, but as moments.
Use the owned effect assets from 01-23/24 to show ad returns and milestones as “a scene where sweat is shed instead of something shady.”
- Gemstone decisions are tied to rewards and premium achievements
- Salt crystals never disappear—effort that endures
- Warm light brings the joy of milestones
Honest Pricing
Set the price like this
You only need to choose the one service you need. We don’t bundle services and sell them together.
Even if the price goes up, we’ll keep the price for those who are already subscribed. If it changes, we’ll let you know at least 30 days in advance—honestly, including the reason.
모르게 올리는 가격도, 해지를 어렵게 만드는 장치도 없어요. 떠나시는 길도 들어오시는 길만큼 분명하게 열어둬요.
If you complete 7 days, we’ll gift you Premium for 7 days. Not for the price—just the experience.
You can export your learning records for free anytime.
With an annual payment, you get two months free. (The applicable scope by service will be provided when pricing is finalized)
Privacy
You always decide who can see my records. By default, it’s set to “Only me.”
Transparent Operations
모르게 올리는 가격도, 해지를 어렵게 만드는 장치도 없어요.
Honest Rewards
There’s nothing you get by luck. It’s exactly as much as the sweat you’ve shed.
