A free tier that's genuinely useful, five student plans priced to the tutoring you actually use, a one-time pass for finals, a family plan, and one honest line for schools. No dark patterns, no ads, no data sold.
Pay for the amount of tutoring you actually use. Every tier is unlimited within fair use — the difference is how much depth you get before a busy day shifts to the lighter model. Start free, move up only when you outgrow it.
Switch to annual for two months free.
A light load — one or two classes.
A normal full semester.
Heavy weeks, several classes.
The grind — MCAT, finals, a thesis.
All-day, every-day power use.
Every plan is unlimited Socratic tutoring within fair use — the hours above are the ceiling almost no one reaches, and they stretch further once a busy day shifts to the lighter model. Your materials stay private and are never used to train AI. Cancel anytime, 7-day refund on any charge.
15 tutor messages and 3 recall reviews a day. A real plan, not a timed trial.
Exam Sprint because subscriptions during finals are cruel. Family because parents pay for peace of mind. Institution because your school would rather not hand a student a credit card.
6 weeks of full access to survive finals.
a week on this plan: Six weeks of Student-tier access, then it stops on its own.
Up to three students. Aggregate parent view.
Schools, districts, university departments.
Everything else is the same on every plan — unlimited tutoring, recall and explain-back, the output guard, your private materials, the weekly Brain score. These are the lines that actually move, and every one is enforced in code.

If you’re already paying for another study or general-purpose AI tool, Brainback is almost always a downgrade in monthly cost and an upgrade in what the tool actually does for your grades.
| tool | their cost | brainback | annual savings |
|---|---|---|---|
| ChatGPT Plus | $20/mo → $240/yr | $9.99/mo → $99/yr | $141/yr |
| Chegg | $15.95/mo → $191/yr | $9.99/mo → $99/yr | $92/yr |
| Course Hero | $39.95/mo → $479/yr | $9.99/mo → $99/yr | $380/yr |
| Photomath Plus | $9.99/mo → $119/yr | $9.99/mo → $99/yr | $20/yr |

7 days, no questions. Any monthly or annual charge — email support@brainback.chat within 7 days of the charge and we’ll refund in full. No cancellation survey. No “are you sure” guilt-trip. Sprint refunds honored if you’ve used less than 20% of the 6 weeks.
Beyond the 7-day window, we don’t pro-rate — you keep access through the end of your paid period. If a specific hardship makes that unfair (job loss, family emergency), email us. We’ve never turned anyone away.
A short list of things we refuse to monetize as add-ons. Every one is either free-tier or Student-plan, and none is ever locked behind a microtransaction.
There is no such purchase, ever. The refusal is the entire product.
Not for sale. Bypass would collapse the tool for the users who benefit from it.
Every hint costs Brain points. Points are not for sale.
Every grade uses the same rubric + Haiku call. No tiered accuracy.
Output guard runs on every account, every reply. No plan disables it.
One click. No survey. Access through end of paid period.
Because subscriptions during finals week are predatory. Sprint is a one-time $24.99 that grants full Student access for 6 weeks — no auto-renew, no reminder emails, no guilt about canceling. Pay once, cram, be done.
Free tier is genuinely useful for a week or two. If Brainback isn’t making a difference for you by then, don’t upgrade. If it is — Student ($9.99/mo) is the sweet spot, and there's a plan above and below it.
