StepSolve: Verifiable STEM Homework Coach
Upload a photo of your math, physics, or circuits homework and a real computer algebra system checks every line — pointing out exactly where the derivation breaks and explaining how to fix it.
Undergraduate engineering and physics students who need step-by-step help, not just a final answer, and want to trust the check because it's symbolic not guessed.
- Photo or PDF upload of handwritten work, automatic transcription and symbolic checking via SageMath backend
- Line-by-line replay with circle on the exact step a sign, term, or factor was dropped or inverted
- Plain-language explanation of the symbolic error ('you assumed the lower limit was zero but it's actually L')
- Course-set mode where the student tags the assignment, due date, and gets a prioritized fix-list before submission
New research shows LLMs alone hallucinate up to 30% of math steps, but pairing them with a CAS lifts accuracy dramatically — students currently rely on tools that are either untrustworthy AI (ChatGPT) or final-answer-only (Wolfram Alpha) and have no reliable middle ground.
Multiple 2025/2026 roundups list 6-15 leading AI math solvers; Photomath reportedly solves ~94% of calculus problems per comparison data, signaling large active user base among students.10 Homework Help Platforms Compared: Pricing, Features, and What They Actually Teach ↗6 Best AI Math Solvers for Students in 2026 (Step-by-Step) ↗
Market is saturated: Photomath, Symbolab, Wolfram Alpha, Mathway, MathGPT, Mathly, Cymath, Microsoft Math Solver, Socratic, StudyX, Chegg all already offer photo-input step-by-step solutions; Symbolab in particular already wraps CAS around answers, leaving little white space for a similar offering.13 Best Symbolab Alternatives (2026) ↗Photomath vs Symbolab 2026: Which Math Solver Wins? ↗
Proven subscription pricing across category: Chegg ~$14.95/mo, Wolfram Alpha Pro ~$7.25/mo, Symbolab Pro and Photomath Plus both use freemium tiers with step-by-step paywalls — students demonstrably pay for step explanations.10 Homework Help Platforms Compared: Pricing, Features ↗Photomath vs Symbolab 2026 ↗
STEM curricula persist for decades; CAS-augmented tools upgrade as CAS systems improve
Building blocks exist (SymPy/SageMath CAS, GPT-4V/Claude vision, LaTeX-OCR), but engineering line-alignment between a photo's handwritten steps and CAS-checkable expressions plus physics/circuits domain modeling is non-trivial; Photomath already proved the OCR+step pipeline at scale.Best AI Homework Helpers (2026): Photo Solve & Step-by-Step Answers ↗
