Pay once. Only the year of updates is renewable.
Buy it once
One payment, with a year of updates: every version released in that year installs. When the year ends, Folding Mirror goes on working, resting on the last version you are entitled to.
No subscription and no account. The assistant runs on your own API key, billed to you by your provider directly.
One edition. No personal-versus-pro fork.

- 3 machinesOne key across macOS, Windows and Linux. Commercial work included.
- 30-day refundOne email, no questions. And 14 days to try before you pay.
There is one thing to explain: what happens after a year.
Which versions this buys
Every one released in the next year. When that year is up, nothing happens.
- Day 0
- You pay. The key arrives by email — one key, every platform. Install and write.
- First 12 months
- Every version released in that window installs, major versions included, at no further cost.
- After 12 months
- The software rests on the last version you are entitled to. No expiry, no read-only mode, no nagging.
- To get newer ones
- Another year of updates for $12, renewable whenever you like. Not renewing takes nothing away from the copy you have.
Renewal always costs less than buying fresh, the early-bird price included.
One key, 3 machines
How machines are counted
3 in total across platforms: a desktop, a laptop, the machine at work, and you are full. When a 4th one starts up, the machine you have used least steps aside: it stops receiving updates and otherwise carries on. You never write in to free a slot, and reinstalling your OS does not cost you one.
Commercial use is included
There is no personal-versus-business split: the ordinary key covers paid work. For a team, write to support@foldingmirror.app and the keys are issued by hand.
14 days to try, 30 days to change your mind.
Bought wrong? Take it back
14-day trial
What you download is the complete app, fully usable for 14 days — no card, no account, not even an email address. After that it turns read-only, and everything you wrote is still sitting in your own folder, ready to be read or exported.
30-day refund
Write to support@foldingmirror.app within 30 days and you get all of it back, no questions asked. The one exception is a resold key.
Do I have to keep paying?+
No. You pay once and keep it. When the year of updates runs out, Folding Mirror goes on working, just on the last version you are entitled to. Renewing is only for getting newer ones, at $12 a year.
What do I lose if I never renew?+
Only future versions. The copy on your machine does not expire and never turns read-only.
What happens when I change computers?+
One key runs on 3 machines at once, counted across macOS, Windows and Linux together. Put the same key into the new machine. When a 4th one shows up, the machine you have used least stops receiving updates and otherwise carries on. You never have to write in to free a slot.
Do I need a business licence to use it at work?+
There is no separate business edition — the ordinary key covers commercial work. For a team, write in and the keys are issued by hand.
Does the AI assistant cost extra?+
No. Folding Mirror sells no credits and resells nothing. You bring your own API key, and the usage is billed to you by your provider directly.
Use it first.
Talk money later.
Install it, write something long, and 14 days will tell you whether this is the sheet of paper you wanted.
