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.
API docs that humans and AI agents ship together
Paste an OpenAPI, GraphQL, gRPC, SOAP, or AsyncAPI spec and Theneo builds a complete, navigable API reference with code samples and a versioned playground.
Engineers, writers, and PMs edit in the same document with live cursors, comments, version history, and one-click rollback, so docs stop drifting from the product.
Automatic changelog generation flags breaking changes as APIs evolve, keeping a timeline developers can trust.
An Ask AI assistant answers developer questions from your docs, and an MCP server plus llms.txt make the content usable by coding agents.
