Homework that ends. Misses that return.
Snap or type tonight's problem. You get guided instead of handed an answer, teach-back is there when you want to check your understanding, and saved misses return when they're due — 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
Use this learning loop to work through a problem and practice it again later. Teach-back is recommended and you can skip it:
- AskSnap a photo or paste the problem.
- Guide meOne question at a time until you can take the next step.
- Teach backRecommended: you explain it, Sugar grades your explanation. You can skip it.
- LaterThe saved miss returns in Practice when it's due.
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 is recommended, not required
After an explanation, a Teach back pill appears: you explain the idea in your own words and Sugar grades your explanation. It helps you check whether you understood the step or just watched it happen. If your explanation has a hole, that hole gets saved by name.
You can skip this check and return to Practice later. Skipping leaves your understanding unchecked; it does not count as an independent success.
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.
Today's review is complete
When today's scheduled cards are finished, the app says so and stops asking for more. No streak to protect, no points to farm, nothing left blinking. That closes today's review — not your homework or your access to Ask, which stays open if you have another problem to bring.
Misses return when they're due
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. Saved misses return when they're due, spaced further out as you get them right, so you practice the method again 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. It's recommended, not required — you can skip the check and return to Practice later.
- Who pays?
- Start free — no card required. Every new account starts on Lo-Fi, free forever, with 10 messages a week. Thrifty is $99 a year, or $49 your first year with the founding offer. Students aged 13–17 are never asked for a card: a parent approves the account by email and pays. Adult students (18+) can pay for themselves.
