Not just another file folder
From a pile of files to everything in one place, organized by what it's for.
Traditional computer finders give you one long, flat list of folders and files. Even in gallery view it's impossible to tell what is happening. Stacks gives you one place for each thing you own — like your house — with the smaller pieces living right inside it: insurance, property tax, utilities. Everything in view, so you can tell what's missing at a glance.
No structure, no context — just names in a folder.
One place. Every piece inside it, and its status, at a glance.
Hours you don't get back. Money you didn't have to lose.
Tracking every bill, policy, and renewal by hand costs more than you think — in time, in fees, and in the stuff you forgot to cancel or renew.

a day to stay fully on top of everything you own, once Stacks takes over
- Digging through drawers and inboxes for the one document you need
- Guessing when your policies and licenses actually renew
- Getting hit with late fees and price hikes you never saw coming
- A patchwork of sticky notes, folders, and "I'll deal with it later"
- Every document filed the moment it lands — no digging, ever
- Renewal dates tracked automatically, with a gentle nudge beforehand
- Fees and price hikes flagged before they hit your account
- One calm place that quietly runs itself in the background

Questions
Everything you're wondering, answered.
The short version of how Stacks actually works, before you hand it your paperwork.
You drop a document into your Inbox — or email it, snap a photo, or connect a Smart Folder. Stacks reads it, figures out which asset it belongs to (your house, car, an account, a business), and proposes where to file it. Tap to confirm, or let it file on its own once it's learned the pattern. No AI required to make that decision — it's deterministic, so the same document is always filed the same way.
Yes. Your documents are encrypted in transit and at rest, and only you have access to your domains. Stacks never sells or shares your paperwork, and you can export or delete everything you've stored at any time.
A few minutes. Create your account, name your first stack — house, car, whatever you want to get on top of — and start dropping files in. There's no configuration, no templates to build, and nothing to train before it starts working.
Bills, policies, statements, renewal notices, tax documents, warranties, contracts — basically anything with a due date, a dollar amount, or a decision buried in it. If it lands in your mailbox or inbox, Stacks can probably make sense of it.
No. That's the whole point. Stacks proposes a home for every document the moment it arrives, so you're never staring at a blank folder structure trying to decide where something goes.
Yes. Once Stacks knows about a policy, license, or bill, you can set a cadence for it — Stacks gives you a gentle nudge at the right time instead of leaving you to remember on your own.
Everything in its place. Nothing left behind.
Paper or digital, give it one calm place to live. Start with the pile that's bugging you most.
