Solvely

Where Solvely sits

Solvely is a study tool built around a very specific moment: it is 11pm, there is a problem on the page you cannot get past, and you want the steps, not just the answer. The product ships by Aignite Inc. and has grown from a photo math solver into a full study suite — homework solver, flashcards and quizzes, mock exams, live lecture notes, and a small writing toolkit — but the solver is still the front door, and it is the part worth judging hardest. The apps carry real weight: 5M+ downloads and a 4.9-star average across roughly 91,800 reviews on Google Play at time of writing, and 4.7 to 4.8 across tens of thousands of ratings on the App Store. Whatever else is true, a large number of students use this thing daily and rate it highly.

What I look for in this category is narrow and unforgiving: is the OCR honest about what it read, is the working genuinely step-by-step rather than a decorated final answer, and does the pricing respect a student budget? Solvely does well on the middle question, has an unusually candid answer to the first, and stumbles on the third.

What it actually does

The core loop takes a photo, a PDF, a pasted screenshot, or typed text and returns a numbered solution with reasoning at each step. The company says it routes each problem through multiple AI models and compares their answers before showing you one — a cross-check aimed at the confident-wrong-answer failure that plagues single-model solvers — and it advertises 'up to 95% accurate' step-by-step solutions on its own pricing page. After the solution, an AI tutor takes follow-up questions ('why does step two work?'), and you can tap individual steps for a drill-down explanation, which in my experience is where errors surface. For visual subjects it renders diagrams, graphs, and 3D geometry inline rather than dumping text.

Around the solver sit the study tools. You can upload files (lecture notes, past exams, PDFs, slides) and get flashcards, adaptive quizzes, mock exams in your class's format, cheat sheets, and review plans. AI Live Notes records and transcribes lectures into timestamped, searchable notes. The writing block adds a humanizer, an AI detector, plagiarism checking, and citation help. Coverage runs from arithmetic through calculus and statistics to physics, chemistry, biology, programming, and essay feedback.

Pricing at time of writing, straight from solvely.ai/pricing: the Starter tier is free and includes exactly 2 solves. Pro is advertised as '$0.57/day', which unpacks to $3.99 for the first week, then $8.99 per week billed weekly, covering unlimited solves, multi-model verified answers, flashcards, quizzes, mock exams, cheat sheets, and the writing tools. The pricing page carries Weekly/Monthly/Yearly toggles, but the monthly and yearly figures are not rendered in the page I pulled, and third-party trackers disagree with each other — one lists a $8.99 monthly Unlimited plan, another quotes $1.99 for a first week then $6.99 a week. I could not reconcile these from Solvely's own surface, so I report the weekly rate I verified and flag the rest as unresolved. What is not in dispute is the shape: the default and best-publicized path is a rolling weekly subscription that costs roughly $39 a month if you keep it running — more than most monthly study subscriptions.

My testing notes

Three observations from working with it. First, the free tier is a demo, full stop. Two solves is roughly one photograph of a worksheet with two problems on it. App Store reviews say the same thing in blunter language — multiple reviewers describe hitting the wall after two questions and pleading for an ad-supported model instead. I understand why the cap exists (each solve runs several models), but two is low enough that you cannot evaluate accuracy across a real homework set before paying, and with a weekly billing cadence that evaluation window matters.

Second, the step output is genuinely good when the subject is structured. On algebra, single-variable calculus, and standard statistics problems, the working showed the decision at each step — why the discriminant matters, what the factoring move accomplishes — rather than hiding the reasoning. The per-step drill-down is the feature I would use to study: forcing the tool to defend one step at a time is exactly the pressure that exposes a wrong turn. Third-party accuracy testing puts the solver at 95%+ on algebra and 90 to 95% on calculus and statistics, with degradation on improper integrals, proofs, and multi-variate problems, and that matched the pattern I saw.

Third, and most interesting: Solvely's own blog is the most honest writing I have read about why photo solvers fail. Their post on photo math solving describes exactly the trap — the OCR misreads a short minus sign or flattens an exponent so x squared becomes x2, and then the model produces a page of beautiful, correct steps for the wrong problem. Nothing warns you, because from the model's side nothing went wrong. Their fix is the multi-model check plus an echoed transcription of the question above the working, and their advice — read the echoed question before you read the answer — is the single highest-value habit for anyone using this category. I tested the failure mode deliberately with a creased page and a poorly lit photo: the read-back caught a misread exponent before I wasted time on the steps. That read-back deserves to be standard in every solver.

What it does not do

Geometry is the weak spot: OCR struggles with figures and multi-step proofs are frequently misinterpreted, which matters if geometry is your hardest class. Humanities output is generic — structure and grammar feedback is fine, literary or historical argument is surface-level, and a general chat model does that part better. There is no human tutor and no accuracy guarantee; the company publishes an Honor Code page positioning the solver as a study aid and puts the use-or-misuse judgment on you. The weekly pricing is the biggest practical limit: keep Pro for a month and you have paid around $39 for what competitors sell monthly for $10 to $20, and the billing cadence is easy to forget. The 2-solve free tier cannot validate anything. And the accuracy claims do not agree with each other — the homepage says 97% overall accuracy across 200 million-plus problems solved while the pricing page says up to 95%, and both are vendor numbers measured on their own terms.

One more practical note on workflow: the browser extension that grabs problems off whatever page you are on removes the photo step entirely for on-screen homework, and the equation solver path is faster than a scan when the problem is already typed out. My advice for a two-week evaluation: use your two free solves deliberately on your hardest subject, read the echoed question every time, and run one problem you already know the answer to before you trust the tool with one you do not.

Verdict

Solvely does the hard part of this category well: it reads messy student problems with reasonable reliability, it shows working you can learn from instead of an answer you can copy, and its cross-check plus read-back combo addresses the failure mode that actually burns students. I rate it 3.7 for strong core solver functionality and genuinely useful step-level explanations, docked for a free tier too small to evaluate honestly, a weekly billing default that is expensive for what you get, geometry and humanities weaknesses, and vendor accuracy claims that contradict each other even in the fine print. If you are a student in a structured-STEM class who wants to understand method, it earns its subscription during exam season — just buy a defined window, check the echoed question every time, and cancel before the weeks stack up.
