EduBrain
EduBrain is a free web-based education homework helper that covers 90+ subjects, from algebra and physics to history and Spanish. You paste a question, upload a photo or PDF, or record audio, and it returns step-by-step solutions without creating an account. The core solver sits alongside subject-specific pages, math calculators, citation generators, and study tools like flashcards and diagram makers.
Most homework apps focus on one subject or one input type. EduBrain runs the same upload-and-solve flow across math, STEM, humanities, and language pages, then adds optional human expert help for presentations and proofreading. The trade-off is clutter on the free tier: ads during use, a one-file upload cap (32 MB, formats txt/pdf/doc/png/jpeg/jpg), and a five-slide limit on AI-generated presentations unless you subscribe.
The site fits students from elementary through college, STEM majors who need formula breakdowns, international learners using eight interface languages, teachers building quizzes and notes between classes, and adult learners reviewing coursework. Privacy messaging says uploaded files are processed temporarily and removed after the task completes.
