Homework that ends. Misses that return.
Snap or type tonight's problem. You get guided instead of handed an answer, you prove you understood it, and the thing you missed comes back tomorrow — not never.
Pasting it into a chatbot ends the night, not the gap
A general chatbot hands over a finished solution. The homework closes, the page looks done, and nothing about tomorrow's quiz changed. The other version of that night is worse: you stare at one problem for forty minutes, get nowhere, and go to bed behind.
Both end the same way — the gap is still there, and nobody wrote it down.
The loop beats the ask
One question answered is worth one night. A loop is worth the term. Every problem you bring goes through the same four beats:
- AskSnap a photo or paste the problem.
- Guide meOne question at a time until you can take the next step.
- Teach backYou explain it. Sugar grades your explanation.
- TomorrowWhat you missed returns as a short recall question.
Guide me is the default
Every new question starts in Guide me. Sugar restates what the question is actually asking, asks what you'd try first, then gives one step and stops. Get it wrong and it names the specific mistake instead of restarting from the top. Explain and Answer are there when you need them — you pick them on purpose.
Teach back proves it stuck
After an explanation, a Teach back pill appears: you explain the idea in your own words and Sugar grades your explanation. It's the fastest way to find out whether you understood the step or just watched it happen. If your explanation has a hole, that hole gets saved by name.
Practice Today is five minutes, not a session
Open Practice and you get one cover: the concept, how many cards, about how many minutes. Usually five. You grade yourself Forgot, Shaky, Solid or Easy, and the schedule decides when each card comes back.
You're done for today
When the cards are finished, the app says so and stops asking for more. No streak to protect, no points to farm, nothing left blinking. Homework that ends means the screen agrees the night is over.
Misses return on their own
Every miss is saved as a short, plain-language name — the actual thing you got wrong, linked to the class and the test date if you gave us one. It comes back tomorrow, then spaced further out as you get it right, and it reopens before the exam.
13 to 26, and the parent who pays
Middle school through university. Under 13 can't sign up. If you're 13–17, a parent approves your account by email first, and we never ask you for a card. 18 and over can pay for themselves.
- Is this a tutor or an answer machine?
- A tutor. Guide Me is the default on every new question: Sugar asks what you'd try first, gives one step, then stops so you do the next line. Answer mode exists, but it's a choice you make — not the default.
- How do I use it without copying?
- You do the writing. Sugar restates the question, names the exact step you're missing, and quizzes you after. Teach back flips it: you explain the idea in your own words and Sugar grades your explanation.
- Who pays?
- A parent does, if anyone. Lo-Fi is $0. Thrifty is $99 a year — less than one tutor hour — and we never ask a student under 18 for a card. 13–17 year olds need a parent's approval by email before they start.
