Homework Helper: Step by Step

DoubtGo is a study app that helps you understand your homework, not just finish it. Ask any question, record a lecture or upload your notes, and get clear study help for every subject.

SOLVE HOMEWORK STEP BY STEP
• Snap a photo of any math or homework question and get a clear solution with each step explained.
• Math solver from algebra to calculus, with the method explained, not only the final answer. Geometry, physics and chemistry problems are covered too.
• AI tutor chat: ask a follow-up question any time and get a plain explanation you can follow.
• Works across math, science, history, English and more, so one homework helper covers your whole week.

TURN LECTURES INTO STUDY MATERIAL
• AI notes: record a live lecture, upload a PDF, slides or docs, or paste a YouTube link. Get summarized notes you can review anywhere.
• Flashcards in one tap: generate flashcards from your notes, files or any topic, then review them until they stick.
• Study from YouTube: paste a video link and turn it into notes, flashcards and a quiz. Perfect for visual learners.
• Practice quizzes and practice tests built from your own material, so you can check what you know before the exam.

HOW IT WORKS
1. Ask any question: take a photo of the problem, or start from your notes or a lecture.
2. Read the explanation: each step shows the method, so you can follow the reasoning.
3. Quiz yourself: flashcards and practice questions show whether the idea has stuck.

ESSAY AND WRITING HELP
Brainstorm, outline and improve essays and assignments with guided writing support tailored to your topic.

BUILT TO TEACH, NOT JUST TELL
Every answer shows the reasoning, so you learn why a step works. Then quiz yourself to check that it stuck.

WHY STUDENTS USE DOUBTGO
• All in one: notes, flashcards, quizzes, homework help and an AI tutor in a single study app.
• Study on your own time: homework help is there at midnight, the night before the test, or on the bus.
• Built for real material: lectures, PDFs, slides and video links, not only typed questions.

WHO IT IS FOR
High school and college students preparing for homework, tests, quizzes and finals, in every subject.
