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.
Your AI focus coach for macOS
Lock-in tracks real work signals such as tab switches and idle stalls, then nudges you before a three-second glance turns into a thirty-minute detour.
When your focus dips, the app proposes a quick reset — a water break or a sixty-second stretch — drawn from attention research rather than generic timers.
Every session closes with a clear report covering your focus score, the distractions you hit and how long it took you to recover.
The app is built for macOS and runs as a lightweight companion rather than a browser-blocking hammer.
