THE LADDER
Every seat of Founding carries the Pro column — locked forever.
On a phone? Each row reads top-to-bottom: Core · Pro · Ultra.
The guardrails are never the upsell: receipts for every action, a check-in before anything you'd regret, a spend ceiling you set, and a kill-switch — all in every tier. And we never meter you by the token: plans are flat, the keys you bring stay between you and your provider, and the included usage on top is exactly that — included.
FAQ
The thinking part of SynthOS is powered by AI accounts you already pay for (like Anthropic or OpenAI). You plug in your own key or subscription, and that bill stays between you and them — we never meter it or mark it up. Every plan also includes managed usage on top, so it works out of the box. What you pay us for is the cockpit: the app that turns the AI into a team that does real work, remembers everything, and keeps working when you step away.
Same app either way. Monthly keeps it loose if you're still feeling it out; yearly is two months cheaper over the year if you already know this is part of how you work. You can switch between them whenever you like.
The first 50 people to back SynthOS get everything in Pro for $299 a year, locked forever — the price never changes for as long as you keep the seat. The counter on this page is live; when the 50th seat goes, the plan goes with it.
Cancel anytime, in a couple of clicks — and every plan carries a 14-day money-back guarantee. Everything SynthOS ever made for you lives on your own Mac as real files you own, so canceling never holds your work hostage. If a fresh charge wasn't right, write to us and we'll make it right.
Yes — SynthOS is a native Mac app, built to run on your own machine so your work stays yours. You'll want a recent Apple-silicon Mac. There's no web version and nothing to install on a phone; the finished work simply reaches you wherever you already are.
On your Mac, and synced through your private cloud so a second machine picks up where the first left off. The vault is account-bound and encrypted in transit, and sync is yours to turn off per vault. Your credentials never sync — they stay on your Mac. Everything the agents make is real files you own on disk.
Anytime. Move up or down the ladder from your billing page, and switch between monthly and yearly whenever you like — the change takes effect on your next cycle, and nothing you've built is ever touched.
