threenote

Threenote is a note-taking concept and, in some implementations, a software application that organizes information using a triadic structure. The central idea is to divide each note into three components: a concise idea or summary, its context or source, and an associated action or follow-up. This three-part schema is intended to improve capture clarity, traceability, and task-oriented follow-through.

Core features include templates that enforce the three-part structure, cross-note linking to connect ideas, tagging and full-text search, and optional task integration. Many implementations offer offline access and synchronization across devices, as well as a visual dashboard showing relationships among notes and quick filters by component.

Usage involves capturing a brief idea, attaching context such as date, source, or rationale, and recording an explicit action or decision. Users can link threenotes to related items to reveal patterns, and export options typically include plain text, Markdown, and JSON.

History and variants: The threenote concept emerged in the early 2020s as a lightweight alternative to more expansive note-taking systems. Several software products adopted the triadic model, applying different labels and features.

Reception: Analysts have noted that the three-part structure can promote concise capture and task alignment but may feel constraining for users who prefer free-form notes. The approach varies in flexibility and interoperability with other note ecosystems.
