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.

Shows which Reddit threads, YouTube videos, LinkedIn articles and pages sit behind AI answers, so you can prioritise the specific asset worth winning rather than guessing.
Finds AI-cited threads, drafts helpful comments with your brand named naturally, then posts and verifies publication through your own warmed-up Reddit account.
Generates the LinkedIn article, video script and chapter structure, or fact-checked landing page built to beat the source AI currently quotes, with one-click publishing to common CMS platforms.
