On-device AI

Not loaded

Answering and question writing runs in this browser tab. Your text is never sent to TodayAI or an AI service. The model files are downloaded once from Hugging Face and then cached on this device.

Generated answers and questions are checked against your material, but small on-device models still make mistakes. Use the source passages to confirm anything you'll rely on in an exam.

How to use it

  1. Upload a PDF or paste your notes. Text is extracted in your browser and split into numbered passages that keep their page numbers.
  2. Search your material and make cloze flashcards and quizzes without any download, or load the on-device model for answers, explanations and generated questions.
  3. Every answer shows the passages it came from. Review your quiz answers, then export flashcards or a study sheet.

Good for

  • Asking what your lecture notes say about a topic
  • Turning a chapter into flashcards
  • Making a practice quiz before an exam
  • Getting a plain-English explanation of a dense paragraph

Privacy and limits

Your PDF and notes are processed in this browser tab and never uploaded to TodayAI or an AI provider.

  • PDFs up to 25 MB and 300 pages; scanned pages are read with OCR (English, first 20)
  • The assistant only knows your material. If the passages don't cover a question it says so instead of guessing
  • Generated questions are checked against their source passage, but small models still make mistakes
  • Page numbers come from the PDF; pasted notes have passage numbers instead
