Obsidian

What it is

Obsidian keeps notes as ordinary text files on the computer instead of requiring them to live only inside an online service. Users can connect related notes, add tags, search, use templates, and create visual canvases. Optional paid services add encrypted synchronization, shared folders, version history, and web publishing.

Ways to use it

Ideas from real executive operations work. Take the ones that fit.

• Keep a connected operating notebook for recurring meetings, people, and decisions.
• Build a research collection whose source notes remain readable outside the app.
• Create a personal executive briefing system that works without an internet connection.
• Connect project notes to the policies, contacts, and prior decisions they rely on.
• Use templates to capture the same fields for vendors, meetings, or experiments.
