Chat with any PDF, video, or website and get cited answers in seconds
Every response is anchored to your source document with clickable citations that scroll to the exact passage, so verification takes seconds instead of page-by-page searching.
Organize documents into folders and query many files in a single conversation to compare arguments, cross-reference findings, or study a whole syllabus at once.
Condense long papers, reports, and contracts into key takeaways, and translate or query documents in any language — including mixing a source language with a different question language.
Generate flashcards and slide decks from your material, and use the built-in AI writer and AI detector for drafting and checking academic text.

An AI assistant that reads your notes without ever leaving your iPhone
The assistant model runs locally on the device rather than in the cloud, so your notes and documents are never uploaded for processing.
Answers show the notes they drew from, so you can verify correctness and open the source material yourself in one tap.
Write new notes in the built-in text editor, add existing PDF documents, or save websites from Safari or any browser via the share extension, all stored locally.
Lock screen, control centre and Action Button shortcuts, plus a widget, let you capture a thought or ask the assistant without opening the app.
