Tansei — A simple shelf for your Mac
Built for work in motion. Designed to stay close.
What this is
A Mac shelf app that pins clipboard items, files, and snippets at your screen's edge so you can drag them back mid-task, sold as a one-time purchase after a 3-day trial (not actually free).
Our one-line summary — not the founder’s tagline.

The numbersIs it still shipping, is it overpriced, where did it land — and what the price is built from.
League price & chart
No money. No seat. It goes on your record — and in 28 days reality settles it.
Calls are closed while we rebuild accounts. You can still read every one of them.
Design. Launched 8d ago on Product Hunt, picking up 26 votes. Today, the site itself changed 3d ago — evidence it's still shipping, not just announcing.
Quiet for 2 days — no penalty yet, but quiet doesn't stay free.
We check this site every day, ourselves. A founder can post “still working on it” — a claim like that doesn't price. What we price is what we can verify from the outside: evidence, not announcements. The real question isn't “will this be huge?” — it's “will they still be moving in four weeks?”
The market viewHow this launch is priced and ranked in our league — the investor side of the page.
ranked by the reality anchor, not the market price
It launched on Product Hunt with 26 votes.
No matter how much money goes in. There is no pump here — you can't make yourself right by buying more. The line only moves on things that actually happened: an award, revenue that grew, a new platform, code that shipped — or silence.
3 quiet days in between are left out — nothing happened on them. A launch that goes quiet eases down a little at a time — never a cliff you could have run from the night before.
Daily tracking just started for this launch — the first point is on the board. A second reading lands with tomorrow's run, and the curve builds from there.
How the launch is moving on its own board, day by day — the crowd's attention.
A flat line is normal: votes stop within a day or two of launch, on every board. What's unusual — and what actually counts — is a launch that keeps pulling votes long after its day is over.
About
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.

The board it did best on sets the price. Every other board only adds to it if the launch also placed high on that board too — because just showing up somewhere isn't an achievement. Listing on twelve directories is free; placing well on them isn't.
