The study app that works the way your brain actually does.

Notes, flashcards, lecture recording, and a plan for today — one calm place instead of five apps. Built by and for neurodivergent students. No timers, no streaks, no guilt.

Free forever for one course. Plus is $4/mo — less than half of what the apps it replaces cost together.

What Sorrel does

• ☀︎

  One thing at a time

  Today shows a single next block, chosen for you. No wall of overdue anything.

• ✎

  Real handwriting

  Pencil-first notes with lined, grid, or blank paper. Import PDFs and write on them.

• ♪

  Flag the moment

  Record lectures and flag “this will be on the exam” as it happens. Jump back later.

• ▤

  Remember for good

  Spaced retrieval timed to the forgetting curve — long-term memory, not test-week memory.

• ⬇︎

  Catch it, sort it later

  Screenshots, thoughts, to-dos land in one Inbox from any app. OCR included.

• ◈

  Trust your gut, provably

  Confidence checks show when your “I know this” is right. It usually is.
