Switch apps without losing the thread. The color you copied. The line from ChatGPT. The file you’ll need in a minute. Tansei keeps them pinned at the edge of your screen, ready to drag back the moment you need them. Everything stays on your Mac, private by design, no account needed. Try it free for 3 days, then pay once.
A prompt in ChatGPT. A design in Figma. A file in Finder. A link in Safari.
The hard part isn’t finding information.
It’s keeping the right pieces close as you move between apps.
That’s why I built Tansei. It’s a simple shelf for your Mac.
It automatically keeps the text, links, images, files, code, colors, and screenshots you copy, so they’re always within reach. Drag them into any app, paste them with your keyboard, or come back to them later.
Everything stays on your Mac. No account. No cloud.
I’d love to hear how you work:
What’s always open on your Mac?
Which apps do you switch between the most?
What’s one thing you copy over and over every day?
since it auto-captures everything you copy and keeps it all local, does the shelf have any retention or auto-cleanup, or does it just grow forever until you manually clear it? curious how that's handled once you've been using it for months
honestly the pinned-shelf idea looks super handy, but one thing i'd love is a quick keyboard shortcut to call up the shelf and search through pinned items by content, like the actual text from chatgpt or the hex value of a color, instead of just the app it came from
One thing I'd love is a quick keyboard shortcut to pop the shelf open from anywhere, even when it's hidden, so I can grab a clip without losing my mouse position.
love how local and no-account this is, finally. one thing that would honestly make it stick for me is keyboard shortcuts to pin and recall items without reaching for the mouse, like a quick hotkey to grab whatever's currently on the clipboard into the shelf
Love how lightweight this feels and the local-only approach is a huge plus. One thing I'd find really useful: let me group pinned items into named stacks so I can separate work-in-progress from quick-reference snippets, and collapse the whole shelf with one keystroke when I want a clean desktop.
Love that it stays tucked at the edge instead of interrupting your flow. Most shelf apps feel like another dock, but the pinned snippet idea (especially grabbing a line of chat output) is genuinely clever.
the way it just lives at the edge of the screen and gets out of the way is honestly so well done, feels like it was thought through by people who actually use macs daily.
Love that it runs locally with no account, that's exactly what I'd want for something this personal. One thing I'd kill for: a quick hotkey to pin from anywhere, not just drag and drop. Like a global shortcut that grabs whatever's currently in my clipboard without me hunting for the app window first. Would make the whole "without losing the thread" promise even more true.
Pinned a color and some text from ChatGPT to test it out, and dragging them back into other apps felt genuinely smooth. Love that everything stays local, no account fuss.
Pinned a color hex and a ChatGPT snippet earlier and honestly forgot how handy that is when bouncing between apps. Nice that it's all local too, kind of rare these days.
Love the privacy-first approach and the idea of pinning stuff at the screen edge. One thing I'd really want is a keyboard shortcut to instantly summon the shelf and search across pinned items, instead of hunting with the mouse when I'm mid-flow. That'd make it feel even more invisible until I need it.
