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.

Stop typing prompts. Start talking.
Hold a hotkey, speak naturally, and get a well-structured prompt — with goal, context and constraints — typed directly into your active text field.
Dictate five times faster than you type while Lemon cleans up filler words and false starts, leaving only your intended words.
Emails, Slack messages, team updates and notes are rewritten in your tone and matched to the surrounding thread.
Lemon sits in a notch at the top of your screen on macOS and Windows and works with Claude, ChatGPT, Cursor, Gmail, Slack, Notion, Outlook, Teams and more.
