Chat with your data and get charts and diagrams in seconds
Describe the chart you want in plain language and receive a rendered visual, using a chat-style prompt instead of a chart configuration panel.
Go beyond charts to structured diagrams, so process flows and relationships can also be produced from a written description.
No installation or local setup is required — open the site, type your request and work from the generated output.
Produce an initial version of a visual quickly, which you can then refine or restyle rather than building from a blank canvas.
Handwritten notes, PDF markup, and AI study tools on one canvas

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.
