Question AI — Popular Free Alternative Question AI, developed by Singapore-based D3 Dimension, has built a large user base (10M+) by offering core homework-solving features for free. It supports photo uploads, PDF analysis, and covers a broad range of subjects. It also offers a Chrome extension for in-browser solving. However, advanced features are locked behind a paywall, and the free experience can feel limited for power users.
Strengths Limitations
Free core features, large user community Advanced features require paid upgrade
Chrome extension for in-browser help No built-in calculator
PDF upload and summarization Accuracy can vary on complex problems
100+ language support Interface can feel cluttered
Gauthmath (Gauth) — AI + Live Tutor Hybrid Gauthmath, owned by ByteDance, rebranded to Gauth in 2024 and expanded beyond math to cover broader STEM subjects. Its standout feature is the option to escalate to live human tutors on paid plans. The free tier comes with daily question caps and ads. At ~$12/month for premium, it sits on the pricier side compared to alternatives. It also briefly suspended U.S. operations in early 2024 due to regulatory concerns.
Strengths Limitations
Live human tutors available (paid) Free tier has daily caps and ads
Strong camera-based OCR ~$12/month can be expensive for students
High app store ratings (4.6–4.9) No-refund policy has frustrated users
Community features Occasional accuracy issues on complex problems
Photomath — Math-Focused Pioneer Acquired by Google, Photomath is one of the oldest and most recognized math-solving apps. It excels at camera-based math solving with animated step-by-step explanations. However, it is limited to mathematics only — no support for chemistry, biology, literature, or other subjects. Step-by-step solutions require a paid subscription (~$10/month).
Strengths Limitations
Mature, polished camera experience Math only — no other subjects
Animated step-by-step explanations Step-by-step requires paid plan
Backed by Google No writing, literature, or business help
Large established user base Ads on free tier
Mathway — Established Math Solver Mathway is a long-standing math problem solver that covers algebra through advanced calculus. It provides instant answers for free, but step-by-step solutions are locked behind a subscription (~$10/month). It does not support image uploads, which is a significant drawback compared to modern competitors. Subject coverage is limited primarily to mathematics.
Strengths Limitations
Covers wide range of math topics No image upload / OCR
Built-in calculator / graphing Steps locked behind paywall
Billions of problems solved Primarily math only
Clean input interface No humanities or writing support
