Free, local-first, and yours. Pick your platform below; every build is the same app from the same source. Nothing phones home, and there is no account to make.
macOS 13 Ventura or later on an M-series Mac. Intel Macs are not supported.
Open the disk image and drag Sticky Brain into Applications. The build is unsigned — see first launch for the one-time Gatekeeper step.
Windows 10 or 11, 64-bit. ARM PCs run it through emulation.
Installer asks where to put the app and adds a Start menu entry and an uninstaller. Portable is a single exe that runs from anywhere — a USB stick, a Downloads folder — with no install. Both keep data in %APPDATA%\sticky-brain. Unsigned: see first launch.
A glibc-based x64 distro (Ubuntu 22.04+, Debian 12+, Fedora…).
AppImage runs anywhere: chmod +x it and double-click. .deb installs on Debian/Ubuntu with sudo apt install ./StickyBrain-0.1.0-amd64.deb. The vault and Claude work exactly as on the other platforms; Microsoft 365 connects on macOS and Windows, where desktop Outlook lives.
Every build can be verified with the SHA-256 checksums below. Questions? support@stickybrainkanban.com.
Neither build is code-signed yet, so each operating system warns once. That warning is about the missing signature, not about what the app does — the checksums let you confirm you have the file that was published.
A downloaded .dmg carries a quarantine flag, and Gatekeeper will say the app “cannot be opened”. Either right-click the app in Applications → Open → Open (once), or clear the flag in Terminal:
The first time Enrich reads from Outlook, macOS asks whether Sticky Brain may control it. That lives in System Settings → Privacy & Security → Automation and can be revoked any time.
SmartScreen shows “Windows protected your PC”. Click More info, then Run anyway. The installer then asks where to install; the portable exe just opens.
The Microsoft 365 connection works with classic Outlook. Outlook may show its “a program is trying to access” prompt once; allow it, or adjust File → Options → Trust Center → Programmatic Access.
No warning to click through — there is no Gatekeeper or SmartScreen equivalent. Make the AppImage executable (chmod +x StickyBrain-0.1.0-x86_64.AppImage) and run it, or install the .deb. Verify the checksum below if you want the assurance signing would otherwise give.
SHA-256 of each published file. The same list is served as SHA256SUMS.txt beside the downloads.

To check: shasum -a 256 <file> on a Mac, Get-FileHash <file> in PowerShell, or sha256sum <file> on Linux.
The board works with nothing connected. When you want more, the gear opens Settings and you attach things one at a time — each is optional and independent:
| Connection | macOS | Windows | Linux |
|---|---|---|---|
| Obsidian vault | Pick the vault folder | Same | Same |
| Claude | Claude Code, signed in — no API key | Same, via the native Windows installer | Same |
| Microsoft 365 | The Outlook app, already signed in | Classic Outlook, running and signed in | Not available — no desktop Outlook |
Everything else — the one button, the vault safety rules, themes and keyboard — is on the Product page.
