A polished space for notes, tasks, and documents that follows you across every device.
Embed tasks directly inside documents and pair them with a calendar view so planning and execution stay connected.
Choose the structure that matches your thinking — separate work and personal spaces, nested folders, tags, or database-style collections.
Draft, refine, rewrite and summarize content without leaving the document.
Apps for iPhone, iPad, Mac, Vision Pro, Windows and Android with local access when you're offline.

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.
