Try tonight's homework first. Decide later.
Start free. No card required. Every new account starts on Lo-Fi, free forever — nothing charged, nothing to cancel. Ask a real problem, then use Today's Practice on what you got wrong.
For students 13+. Parent approval required for ages 13–17.
The whole thing
- Ask any problem. Snap a photo or type it. Guide me asks you questions instead of dumping an answer.
- Teach back. Explain it in your own words and get feedback on the explanation, not the final number. Thrifty is required for new accounts; older accounts keep their access.
- Today's Practice. A short set built from what you missed — pick one subject if you only want math or science tonight.
- It ends. When the set is done the night is done: You're done for today. No streaks to protect — just a record of your practice.
Lo-Fi is free forever
Lo-Fi is free forever and enough for one class — 10 messages a week. Nothing you saved disappears.
When you want more, Thrifty is $49 your first year with the founding offer, then $99 a year — about $8.25 a month, cancel anytime. Or pick a $39 Semester pass (4 months, no renewal), $59/year Thrifty Student for adults with a .edu email, or $149/year Family for up to 3 students. Students aged 13–17 are never asked for a card: a parent approves the account and pays. Adult students can pay for themselves.
No card is needed for Lo-Fi, so there is never an automatic charge.
Two ways to keep Thrifty
Student: send a payment link
Your parent opens it on their phone and pays $99/year on your account — no account needed on their side. Your trial keeps going meanwhile. The link shows only your first name.
Parent: pay here
Sign in as yourself, enter the code your student makes on their Me tab, and pay on the parent page. You'll also see their weekly progress. Family covers up to 3 students for $149/year.

Ask tonight's problem free, and see whether the misses actually stop coming back.
