Photomath is a scanner. Brainback is a tutor.
what Photomath is
Snap a math problem, get a worked solution.
Photomath scans a math problem and returns a worked solution. It is a lookup tool. Its convenience is real — five seconds from photo to complete step-by-step — and its cost, hidden but real, is that the student never practiced the moves that make the answer land.
Brainback works with you as you attempt the problem yourself. It refuses to return the worked solution until you've completed a hint ladder and a written reflection. And it covers every subject, not just math.
The two products are literal opposites at the level of intent: Photomath optimizes for the fastest path to a completed page; Brainback optimizes for the slowest path that produces understanding.
A student asks the same question of both products. The responses diverge in seconds. The consequences diverge in weeks.
Solve for x: 2x² + 5x − 3 = 0
Formatted step-by-step: 'Using the quadratic formula, x = (−5 ± √(25 + 24))/4 = (−5 ± 7)/4. So x = 1/2 or x = −3.' Clean, correct, submitted.
Attempt: 'quadratic formula'. Correction: the formula is right but you haven't shown work. Try me with a = ?, b = ?, c = ? — three integers, thirty seconds.
No cherry-picked wins. Where Photomath does something we don’t, we say so. Where we do something they don’t, same.
| feature | brainback | photomath |
|---|---|---|
| Solves problems for you | No | Yes, core product |
| Attempt required first | Yes (≥ 20 chars) | No |
| Hint ladder | 5 rungs, priced in points | Single explanation on tap |
| Spaced recall of your errors | Yes, SM-2, auto-generated | No |
| Explain-back grading | Yes, 0–5 | No |
| Subjects covered | All disciplines | Math only |
| Weekly Brain score | Yes | No |
| Works from handwritten photos | Yes, as attempt input | Yes, as problem input |
| Camera-based problem capture | Yes, in Learn mode | Yes, primary UX |
| Cost | $9.99/mo Student | $9.99/mo Plus (also has free tier) |
Monthly prices are how tools get marketed. Annual bills are how they get budgeted. Both matter.
| line item | brainback | photomath |
|---|---|---|
| Monthly price | $9.99/mo Student | $9.99/mo Plus |
| Annual | $59/yr (annual pricing) | $119/yr |
| Savings switching | $60/yr per year | |
Same monthly price. Brainback annual is half. Photomath free tier is real but capped; so is ours.
You’re not just changing tools. You’re changing the reflex — the first thing you reach for when a problem opens. Below is the sequence that works.
The reflex is 'phone up, problem in'. Remove the shortcut for a week and see how often you reach for it — that's the addiction to measure.
Add Calculus, Algebra, Geometry — whichever fit your current class. Everything in those subjects will route through Learn mode.
Even 20 characters of your own attempt unlocks the tutor. The physical discomfort is the entire product working.
Photo of your handwritten work counts as an attempt. Same UX, opposite intent — you're documenting an attempt, not requesting a solution.
After you've worked the problem. This is the healthy adjacent use — verification, not solution.
Keep Photomath as an after-the-fact verifier: solve in Brainback, then scan into Photomath to check your final answer. Never as the first tool.
Every comparison matters to some students more than others. Here’s where the switch from Photomath pays back fastest.
Photomath's biggest user base. The switch here changes what math means to a generation of students.
For students who hit calc / linear algebra and realize copy-paste stopped working.
Every derivation matters. Photomath-shortcut habits kill first-principles reasoning.
Parents who won't allow Photomath find in Brainback the tutor that doesn't undermine them.
Photomath is a tool for students who want to finish the assignment. Brainback is a tool for students who want to learn the material. If both goals are yours, use Brainback for the learning and let the assignment take care of itself.
The specific danger of Photomath is that its output is high-quality: neatly formatted, correctly worked, teacher-legible. That legibility is exactly what makes it a trap — a Photomath-solved problem looks the same as an understood problem on the page, and nothing about the day's homework tells the student which one they turned in.
The exam tells them, six weeks later. That's the moment students switch to Brainback. Our whole product is designed to make that moment happen sooner and less painfully.
Yes — as an attempt-input, not an answer-request. Photograph your handwritten work; the vision model reads it; if substantive attempt is visible, the tutor engages. Photograph the problem statement without work, and the attempt-gate refuses.
A few do. Use Photomath for the specific in-class activity; use Brainback for actually learning. The two workflows sit next to each other cleanly.
For getting a final answer: yes, by design. For getting understanding: much faster in the long run. The compounding shows up between weeks 2 and 4.
Yes — after your Brainback session ends, use Wolfram Alpha, a graphing calculator, or Photomath itself to verify. Verification is a legitimate use. The trap is using it before attempting.
Yes — vision model reads standard notation. Complex integrals, matrices, chemical structures, all fine. The bottleneck is legibility of your handwriting, not the model.
