No central server
Devices sync directly, peer-to-peer. Same-network sync and self-hosting are always free.
Every thought, sorted by time
Everything on your mind, in one infinite outline
Type a thought the moment you have it. Reductable stacks it onto an infinite, self-sorting outline — nest it, tag it, find it again later. An outline that lives on your devices and answers to no one.

How sync works
No central server. Your devices talk directly.
Every device talks to every other directly — no server in the middle, encrypted end to end. Share a branch by tag and a friend on the same network sees just that branch, live. To reach your devices on other networks, put them on the same VPN — a tailnet works — and they sync just the same.

encrypted · peer-to-peer · no sign-up
Direct sync happens when devices share a network — the same Wi-Fi, or the same VPN. Reductable doesn't bridge your network across the internet to a friend's; reaching other networks is what a VPN you control is for.
Built to stay yours
No server in the middle. No sign-up. No catch.
Yours, end to end
Notes live in a local database on your devices. Export everything any time — your backups, your files.
One purchase, every platform
macOS, Windows, Linux, iOS and Android — unlimited devices, one person, one license.
No phone-home
No telemetry, no license check-ins. Your license is an offline token; it works fully offline, forever.
Add-on modules
Reductable does one thing well. When you want more, add a module — a one-time purchase, like the app. No subscription creep.

See full pricingWhat we promise
A privacy policy is a promise. We just don't have your notes.
No accounts on our servers to breach, no database to mine, no copy to change our mind about.
No sign-up, ever
You don't sign up for Reductable. Your identity is created on your device — there's no profile on our servers and no email gate.
Your notes never touch our servers
There's no copy of your notes with us to breach, mine or lose. Export your whole outline any time, and keep backups on your own terms.
No telemetry, no check-ins
The app tracks nothing and never checks your license online — its only automatic request is an anonymous update check. Your license is an offline token, so it keeps working with no network at all.
Questions
Is Reductable ready to use?
Reductable is in public beta. It's stable enough for daily use — we use it daily — but it is beta software: expect bugs, rough edges, and features still landing. Keep your own backups; Reductable exports your whole outline, and your notes stay in your hands either way.
What does beta pricing mean?
US$79 is the beta price, and it rises when Reductable leaves beta. Buy during the beta and you own the app forever at that price — 1.0 and every update after it, on every platform, with no second purchase and no subscription.
Is Reductable free?
Reductable is a paid app that's free forever up to 200 of your own nodes — no sign-up, no card, no time limit. A one-time purchase then unlocks unlimited nodes on every platform, across unlimited devices. Same-network sync and self-hosting are always free.
Is it a free trial that expires?
No. The free tier isn't time-limited and the app never goes read-only — you keep using it free up to 200 nodes for as long as you like. Only creating a new node past the cap is gated, and deleting a node frees a slot. The cap is counted on your device, so nothing phones home to check it. A one-time purchase unlocks unlimited nodes on every platform.
How do I buy it?
From inside the app. Download Reductable, use it free, and when you hit the node cap open Settings → License and press Unlock — the app takes you to checkout with your account already filled in, and your license is bound to it. On iPhone and iPad the in-app purchase arrives with the App Store release; until then, buy from a desktop install and the license unlocks every device. There's nothing to buy on this website, and no sign-up either way.
Do I need to sign up?
No. There's no sign-up and no email gate — the app creates your identity on your device, and none of it is held on our servers. Your license is an offline signed token, so the app keeps working with no network at all.
Does it work offline?
Yes. Reductable is local-first: your notes live on your device and everything works fully offline, your license included.
What platforms does it run on?
We're building for macOS, Windows, Linux, iOS and Android, and a single purchase unlocks all of them, with unlimited devices. They haven't all shipped yet: macOS, Windows, Linux and iOS are installable today, and Android is still on the way. The download page carries the current status for each, including which are still in beta.
How do you sync without a central server?
Your devices exchange changes directly, peer to peer, over the network they share — the same Wi-Fi, or the same VPN, with no sign-up and no third party. It's not a bridge from your network across the internet to someone else's: to sync across networks today, put your devices on the same VPN (a tailnet works). A self-hostable always-on peer is on the roadmap.
Do my devices need to be online at the same time to sync?
Two devices exchange changes when both are awake and can reach each other — on a shared network or the same VPN. Every device passes along what it has, so leaving one running (a desktop at home, say) lets the others converge through it even if they're never awake together. There's no inbox in the cloud catching changes in between.
Is my data private?
Yes. Nothing is tracked, and the only automatic request the app makes is an anonymous update check — its version and platform, nothing about you or your notes. Your notes never touch our servers, and you can export everything any time.
Are updates free?
Yes. Updates to the app are free — there's no subscription for the app itself.
