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.

Turn network briefs, sketches and images into editable topologies
Describe the network in plain language or paste a diagram brief and TopoAI returns a structured, editable first draft.
Upload a hand sketch, whiteboard photo or existing topology image and have it reconstructed as an editable diagram.
Modify devices, links, labels and zones through written or spoken instructions, or work directly on the canvas.
Built-in network and vendor icon sets, reusable templates and an uploadable private icon library for house standards.
