Noah is a desktop app for your Mac or PC. You describe the problem in plain English — "my laptop is slow," "Wi-Fi keeps dropping," "disk is full again." Noah runs a small set of audited tools (processes, CPU & memory, free disk, network, the system log), names the likely cause, proposes a one-sentence fix, and runs it only after you approve it.

Download the installer for your platform from onnoah.app — it detects your OS automatically (or pick Mac / Windows). Open the downloaded file and follow the prompts.

macOS: requires macOS 12 or later (Apple Silicon & Intel). If macOS says the app is from an "unidentified developer," right-click the app → Open → Open to confirm the first time.

Windows: requires Windows 10 or later (x64 & ARM64). If Windows SmartScreen appears, click More info → Run anyway.

You start a 7-day free trial with a card — Noah tracks the trial against an anonymous device ID generated locally on your machine. You're not charged if you cancel before day 7. No account or email is required until you subscribe (or use a magic link to restore an existing account on a new computer).

$50/year (about $4.17/month) or $4.99/month. Every plan starts with a 7-day free trial. A card starts the trial, and you're not charged if you cancel before it ends.

Inside Noah: Settings → Billing → Manage subscription, or directly in Stripe's customer portal. Cancel before day 7 of the trial and you won't be charged.

Yes — if Noah doesn't work for you, email [email protected] within 14 days of purchase and we'll refund you, no questions asked. After 14 days we handle refunds case-by-case.

Open Noah on the new machine and choose to restore your account. We email a magic sign-in link to the address tied to your subscription — click it and your subscription carries over. No password to remember.

Only what your OS exposes to any app: the running processes (the same list Activity Monitor or Task Manager shows), CPU & memory, free disk space, network status, and the system log. No files. No browser history. No passwords. No screen capture. Ever. The conversation is sent to Anthropic's Claude API to generate the diagnosis; we don't store your chat contents beyond serving the request. Full details in the Privacy Policy.

Every change Noah makes is logged and undoable — just say "undo that." Destructive operations require a second confirmation before they run. Noah never executes arbitrary shell or PowerShell commands; each action is a hand-built tool with a fixed, narrow scope.

No. The conversation uses a language model, but every action is a purpose-built tool with a fixed scope — Noah can't run arbitrary commands on your machine. The model decides what to suggest; it can only act through Noah's audited tools, and only after you approve.

No — a dead battery, failing SSD, or busted Wi-Fi card needs physical repair. Noah diagnoses the symptom and tells you when it's hardware, so you know whether to book a repair appointment instead of chasing a software fix.

macOS — if you see "unidentified developer," right-click the app icon → Open → Open. You only need to do this the first time.

Windows — if SmartScreen blocks it, click More info → Run anyway. If your download stalls, try again from onnoah.app; installers are served directly from our own infrastructure.

Yes. A separate open-source "bring your own key" (BYOK) client is available at github.com/xuy/noah. In BYOK mode, no data passes through our servers — your conversations go straight to Anthropic with your key.
