Den

Warning

Alpha (0.1.0-alpha). Not a public release. This is an early, private build for testing. There are no downloads, no signed or notarized binaries, and no support. Things will change and break without notice. Please don't redistribute it.

Your whole Mac in one app: a file manager that remembers what you worked on, plus the small tools you'd otherwise install one by one. Everything runs and stays on your Mac.

• Files and memory: browse folders, recents and projects; search names, contents and text in pictures; every answer links back to where it came from
• ⌥Space launcher: apps, files, calculator, unit conversions, commands, clipboard history, window snapping (⌃⌥ arrows)
• Notch: today's meetings, a file shelf and a question box under the notch
• Storage: what's taking space and what's safe to clear, with the reason for each
• RAM: memory by app and what's growing
• Calendar: month, week and day, with your work alongside your meetings

Build

Needs macOS 26 and Xcode 26 (the SwiftUI macros ship with Xcode, not the Command Line Tools).

cd app
./bundle.sh        # release build → app/Den.app (ad-hoc signed)
open Den.app

Self-check, which drives the real app model headless: swift build && .build/debug/Den --check

Activity engine (optional)

brain.py collects what you touch (git commits, Claude Code prompts, browser history, notes) into ~/.brain/brain.db, which Den reads. It is also an MCP server so Claude can search the same history. See the header of brain.py. local.brain.sync.plist runs a sync every 15 minutes; its paths are for the author's machine, so edit them first.

uv run brain.py sync
uv run test_brain.py

Layout

• app/Sources: the SwiftUI app
• app/Icon: the icon (Den.svg is the source; swift render.swift makes Den.icns)
• app/Parked/Dock: a Dock replacement and widgets, parked and not compiled
• brain.py, test_brain.py: the activity engine and its test
