Stik: Catch a Thought Before It Vanishes

Your brain picks the worst moments to hand you a good idea. Middle of a code review, halfway through an email, ninety seconds before a call. By the time a notes app has opened, synced and asked which notebook you'd like today, the idea has left the building.

Stik is built for exactly those three seconds. It's a free, open-source Mac app that does one thing: press Cmd+Shift+S from anywhere, a floating post-it appears over whatever you're doing, you type, you press Escape, and you're back to work. The note is already saved as a plain markdown file in ~/Documents/Stik/. No account, no cloud, no onboarding wizard asking about your goals in life.

Full disclosure: this discovery is based on the project's official site and GitHub repository, not a hands-on test. The code is public under an MIT license, and the install is a normal .dmg or a quick brew install --cask stik.

One shortcut, one post-it

The whole app is a refusal to make you manage things. The capture window floats over any app and auto-saves as you type. Every note is a plain .md file you can open in any editor, which means no proprietary database and no export funeral the day you leave. Want sync? Point iCloud Drive, Dropbox or Syncthing at the folder and you're done. Push a folder to a git remote and Stik even keeps it synced in the background for you.

If a thought deserves to stare at you, you can pin a note to the desktop where it stays on top of everything else. There's also a capture streak that counts your daily habit and an "On This Day" feature that resurfaces notes from past years, which is either lovely or incriminating depending on what you wrote.

Quietly smarter than a sticky note

For an app this small, the feature list is suspiciously long. Cmd+Shift+D dictates straight into the current note using WhisperKit on the Neural Engine, so the audio never leaves your Mac. Cmd+Shift+C grabs whatever text you've selected in Safari, Terminal or VS Code and appends it to a Clips note, no copy-paste gymnastics required.

Semantic search and folder suggestions run through Apple's NaturalLanguage framework, entirely on-device: no cloud, no API keys, no note content sent anywhere. The editor itself handles markdown with syntax highlighting, wiki-links, task lists, tables, slash commands and a vim mode for the brave. You can encrypt a note with AES-256 and reopen it with Touch ID, import your Apple Notes in one go, and theme the whole thing to match your setup.

The fine print

It's Mac only, and specifically macOS 14 (Sonoma) or later. Windows and Linux users get nothing here, and the first launch asks for Accessibility permissions, which the global shortcut genuinely needs. The interface speaks English and Simplified Chinese. Anonymous analytics exist but are off by default and strictly opt-in, with note content never collected.

It's also a young project: the repo started in February 2026 and sits around 270 stars, so expect a fast-moving changelog and the occasional rough edge. The beta channel installs next to the stable app if you like living slightly dangerously.

The verdict

If you're on a Mac and your best ideas keep escaping between apps, Stik is worth the two minutes it takes to install. It doesn't want to be your second brain or your life's operating system. It just catches the thought before it disappears, files it somewhere boring and future-proof, and gets out of the way. Sometimes that's the whole job.
