Ask any way

However the question shows up, ask it your way

Type it, say it, or photograph it. DoubtGo meets you where the doubt is.

Type it

Write the question in plain words — or paste it in. Great for word problems, definitions and "explain like I'm 12".

Speak it

Tap the mic and just talk. Perfect when your hands are full of homework or you're studying on the move.

Snap it

Photograph the page or pick from your gallery. Scout reads diagrams, graphs and handwriting too.

Study Sets

Answers fade. Study sets make it stick.

Every solve, PDF and lecture becomes ready-to-use flashcards and quizzes — built for you, automatically.

Flashcards that remember what you forget

DoubtGo writes the cards for you and schedules them with spaced repetition, surfacing the ones you're about to forget right when you need them.

  • Auto-generated decks from any solve, note or document.
  • Mastery tracking — see exactly which cards are locked in and which need work.
  • Quiz mode with timed speed rounds, scores and instant "why" explanations.

Drop in a PDF, get a study set back

Upload a chapter, worksheet or slide deck and DoubtGo reads every page — then hands you clean notes, flashcards and a practice quiz built around it.

  • Works with textbook chapters, lecture slides and handouts.
  • Multiple sets per document — split a long PDF into focused topics.
  • Keeps the original alongside, so you can jump back to the source.
