Handwritten notes, PDF markup, and AI study tools on one canvas
Low-latency ink with palm rejection, cross-out to erase, and handwriting-to-text conversion keeps writing close to pen on paper.
Import contracts, papers, or textbooks and mark them up by hand, with searchable annotations and clean exports.
Search across typed text, handwriting, and sketches, and turn notes into summaries, mind maps, or structured plans.
Work together in shared notebooks, documents, and whiteboards simultaneously, without version conflicts or file ping-pong.
AI LaTeX assistant: turn notes, PDFs, and handwriting into clean LaTeX
Converts handwritten notes, photos and screenshots, scanned papers, Word documents, tables, and spreadsheets into LaTeX code that compiles rather than a rough approximation you must retype.
Uploads multi-page PDFs and lets you choose which pages to convert, returning one structured document with sections, numbered equations, tables, and figures in the right places.
Reads equations, matrices, integrals, and aligned derivations at a stated 98%+ accuracy, and can turn diagrams and plots into TikZ.
Drafts abstracts, summaries, and thesis statements; rewrites for clarity without losing your meaning; and looks up citations with BibTeX in the same place.
