Making Sense of Complexity

That's what Ket means. That's what we built.

Life is messy. Knowledge is messy. Your tools shouldn't be.

"Ket" is short for Zettelkasten - the atomic note-taking method that helps you make sense of complexity. Not by forcing rigid organization. By letting connections emerge naturally. That's our ethos. That's how we build.

KetBook is AI that actually understands this. It reads files. Sends emails. Creates calendar events. Searches the web. Reorganizes your notes. All automatically. All with multi-step reasoning that finds the connections you're looking for.

We didn't build another chatbot that makes you copy-paste. We built VaultPsi - autonomous AI that sits in the background, watching your vault, detecting patterns, quietly reorganizing everything to make sense. It's not waiting for you to ask. It's already working.

Want to know what it did? Action Log shows everything. Every tool call. Every decision. Every file it touched. Complete transparency. No black boxes.

This is what happens when engineers who built Apple Keynote and iWork rethink how AI should work. Not as a web app you visit. As a native Mac app that makes sense of your complexity.

Why We Built This

Intelligence That Finds Patterns

VaultPsi watches your vault in real-time, detects connections, suggests reorganizations. It doesn't just execute - it understands your complexity and makes sense of it.

Workflows That Actually Work

Multi-step reasoning handles the messy parts automatically. Ask it to prep for tomorrow's meeting - it reads the agenda, searches background, drafts talking points, schedules reminders, emails the team. Complex task. Simple request.

Transparency Over Trust

Action Log shows every decision, every tool call, every file touched. No black boxes. You see exactly how it made sense of the complexity.

Native. Not a Web App.

Built with Swift 6. Controls Mail, Calendar, Notes, Finder through Apple Events. Menu bar access. iCloud sync. Feels like macOS because it IS macOS.
