The years when learning habits either form or don't. Brainback makes the habit inevitable.
High school is where most students first meet AI answer-machines — and where habits either root or rot. Brainback replaces the copy-paste reflex with a real workflow: attempt, reflect, hint, attempt again, recall. It's the same struggle great students have always had, minus the parts nobody misses.
You'll want to declare your classes in Settings on day one. That's the switch that makes Brainback treat physics as physics and everything else as Efficiency mode.
An honest before-and-after — the specific gaps Brainback closes for a student in this stage of the arc.
Same problem. Same student. Two different definitions of “productive.”
The actual daily shape of a Brainback week for this stage. Adjust for your own load — the rhythm compounds even if the volume varies.
10 recall cards over morning coffee. Class problems in Learn mode after school.
Same. Add one explain-back on today's new concept.
Recall queue only if it's a big-homework night — 10 cards while dinner cooks.
Learn mode for the biggest homework of the week. Explain-back on anything shaky.
10 cards. Free evening — you earned it.
Optional. If you have a test Monday: one long Learn session on the shaky concepts.
Brain score arrives. Ten cards. Ten minutes total. Ready for the week.
None of these are automatic. Each is a signal that the product is working — or isn’t. If you don’t hit the week-4 milestone, revisit the plan.
First attempt-gate refusal. The moment the product either lands or bounces.
First 'yes I actually got it' moment — usually when a concept lands after four hint rungs.
First real Brain score. 55–65 is normal. The trend line is what matters.
Recall queue starts catching things you didn't know you'd forgotten. This is the point of no return.
Test grade closely tracks the Brain score. No surprises. That's the whole product.
Not a magic diet. A specific sequence of habits Brainback builds around you. The pace is designed for a student with a normal life outside coursework.
Add your classes as Learn subjects. Turn on parent dashboard if a parent's paying. Do one problem per class in Learn mode — feel the attempt-gate.
Every homework problem starts in Learn mode. Aim for 4-5 explain-backs a week. Ignore the Brain score for now — it's measuring.
First Brain score arrives on Sunday. It'll be 55–65. That's the baseline. Note which subject is lowest — that's next week's focus.
Recall queue starts to matter. Ten cards in the morning, five in the evening. Ninety seconds a session, twice a day.
Brain score should be in the 70s per subject. Mid-terms feel less ambush. The habit is running on rails.
Your recall queue caught the tricky bits from every unit. The exam is a checkpoint, not a mystery.
All seven product surfaces are always on. But this stage of the arc weights them differently. Below are the ones a high school student ends up leaning on hardest.
The attempt-gate is the whole reason your grades will move.
Five real hints beat one AI-generated random walk.
The single fastest way to know if you've actually learned it.
The reason last unit's material won't be gone by finals.
Something honest to look at on Sunday. Parents like it too.
Add these as Learn subjects and Brainback treats every problem inside them as academic — everything else goes to Efficiency mode. Every subject below has its own dedicated page with topics, common mistakes, and hint examples.
The subject where the shortcut has always been most expensive.
Where symbolic manipulation becomes second nature — or doesn't.
See the diagram. Not just look at it.
Balance the equation. In the right order.
Systems, not slogans.
The country of unresolved arguments.
Your story. Not a template's.
Recommended plan: Free tier, upgrade to Student if you're in 2+ AP classes. Free covers a normal HS schedule. Two AP classes or SAT prep pushes into the paid tier. See all plans →
We say no to some prospects. Better to be honest here than to have you sign up and churn in week two.
It's the first time my kid has ever asked me for a hint instead of the answer.
Yes, and most students do. Brainback runs in any browser and doesn't announce itself the way a Snapchat notification would. It's a study tool, not a distraction.
Do the assignment there; use Brainback to actually understand the concept before you enter answers. The two are complementary — Brainback trains reasoning; those platforms grade completion.
Only if you tell them. Brainback doesn't proctor; it teaches. Because it refuses to give final answers, it's academic-integrity-compatible on almost every school's honor code.
The parent dashboard shows effort — time on task, sessions completed, Brain score trend — but never the content of your attempts or the tutor's replies. Your work stays yours.
The free tier is genuinely useful — 15 tutor messages and 3 recall reviews a day. If you're taking two AP classes or working toward SAT-level scores, the Student plan ($9.99/mo) unlocks unlimited and pays for itself in a month.

Free tier works. Upgrade to Student ($9.99/mo) if you're carrying two or more AP classes.
