Questions,
answered.
Everything about what Tansei does, where your data lives, and how buying works.
The basics
What Tansei is, and what it can hold.
What devices does Tansei support?
Tansei runs on macOS 15 (Sequoia) or later on an Apple Silicon Mac, or on Windows 11.
How is Tansei different from a clipboard manager like Raycast or Paste?
Tansei keeps what you're using visible instead of storing what you copied. Clipboard managers keep a history. When you want something back you hit a shortcut, open a panel, search, and paste. That's a retrieval step, and it costs you the thread every time.
The shelf stays open beside your work. What you set down is on screen, so there's nothing to recall and nothing to search. Expand it into a full workspace when you're deep in something and tuck it away with a keystroke when you're not. Pin what you keep reaching for. Archive what you're done with. Color and group things as you go.
It's built with native system materials, so it reads as part of the system rather than a panel sitting on top of it. Translucent, layered, out of the way until you reach for it.
The difference shows up when you're prompting. You're refining one prompt, holding two references, and waiting on an answer in another window. That's six things in flight at once, none of which you copied an hour ago. A history is the wrong shape for that. A shelf you can see is the right one.
What doesn't Tansei do?
Tansei has no AI features built in, and that's deliberate. It's built for working with AI tools, not for being one. It isn't a launcher, an automation platform, or a new way of working you have to learn. The shortcuts are the ones your system already uses, and everything works by drag and drop if you'd rather use the mouse.
If what you want is a searchable history of the last thousand things you copied, Raycast is excellent and you should use it. Tansei is for people who'd rather see what they're carrying than go looking for it.
What can I save?
Text, links, images, screenshots, files, PDFs, notes, colors and code.
Can I organize my shelf?
Yes. Search, tag, group, pin, archive or delete items whenever you need.
Privacy & security
Where your data lives, and who can see it.
Where is my data stored?
Everything stays on your computer.
Your shelf is stored locally, and screenshots and files are saved in Documents/Tansei (Documents\Tansei on Windows). Tansei does not require an account or upload your data.
Is my data private?
Yes.
Your shelf never leaves your computer. Tansei goes online for three things: optional link previews, app updates, and a license check that sends your key and an anonymous device code.
Is Tansei safe?
On Mac, every copy of Tansei is signed and notarized by Apple. On Windows, Tansei comes only from the Microsoft Store, which verifies and signs the package.
What happens to passwords?
Passwords copied from supported password managers are automatically marked as sensitive. They appear masked with a lock icon and never leave your computer.
Can I pause automatic copying?
Yes. Pause it from the menu bar or turn it off completely in Settings.
What permissions does Tansei need?
None when you install it.
macOS only asks when you use a feature that requires permission, such as screenshots or voice memos.
Does Tansei work offline?
Yes. Your shelf works with or without an internet connection.
Buying & licenses
Your license, buying, and updates.
Where should I buy Tansei?
On Mac, you can buy Tansei directly from tansei.io or through the Mac App Store.
tansei.io is cheaper at US$7 / A$9. You buy your license directly, download Tansei yourself, and updates come through the app. Direct purchases also tend to get updates first.
The Mac App Store is US$9.99 / A$14.99. Apple handles the purchase, installation, and updates through your Apple account.
On Windows, install Tansei from the Microsoft Store, then buy a US$7 / A$9 license from tansei.io to unlock it.
Is there a free trial?
No. Tansei is a one-time purchase: buy it once and it’s yours forever, updates included. If you have a code, enter it at checkout.
How many computers does one license cover?
One, and licenses are per platform. A Mac license covers one Mac, a Windows license covers one PC. If you work across both, you need both.
Licenses are for individual use and can’t be shared.
How do I activate Tansei?
Your license key is emailed the moment you buy, and shown on the thank-you page. Copy it, open Tansei, and paste it in. Same on Mac and Windows.
The Mac App Store version is the exception. It unlocks automatically, and Restore Purchases brings it back on another Mac.
Is the Mac App Store version different?
It’s the same app. Only two things differ:
Files: App Store downloads stay inside Tansei unless you choose a folder in Settings. Direct downloads save to Documents → Tansei.
License: App Store purchases unlock automatically and can be restored on another Mac. Direct purchases use a license key sent by email.
Are updates included?
Yes. Every update is included and delivered automatically.
What’s new in the latest version?
See the What’s New page for the latest features and the full version history.
Can I recover archived items?
Yes. Restore them at any time, delete them permanently, or press ⌘Z (Ctrl+Z on Windows) to quickly undo a recent archive.
About
The person behind the app.
Who created Tansei?
Hi, I’m Pooja, the solo founder behind Tansei.
I built it after realizing how much context gets lost between the apps we use every day. My work involved constantly switching between tools, copying information back and forth, and trying to remember where everything came from.
Tansei is my attempt to make that workflow feel effortless by quietly remembering what matters.
Can I share feedback?
Absolutely. As an indie creator, I appreciate hearing about feature ideas, bugs, and ways to make Tansei better.
Can I provide a testimonial?
Absolutely. If Tansei has improved the way you work, I’d love to hear your experience. Honest testimonials help other people discover the app and help shape future updates.
