Noah for Mac — an AI that diagnoses and fixes your Mac
Noah is an AI desktop support app for macOS that finds what is actually
wrong with your Mac and repairs it in plain English. You describe the
symptom; Noah inspects the machine, names the cause, shows you exactly what
it will do, and does it with your approval. Every change is logged.
How Noah is different from ChatGPT
ChatGPT can tell you what commands to run. Noah can inspect your Mac
itself.
ChatGPT works only from what you describe to it. It cannot see your
Mac, so it answers the average version of your problem and leaves you to
run Terminal commands and interpret the output. If the first guess is
wrong, you start over.
Noah reads the machine's own state: running processes and what they are
doing, memory pressure and swap, disk usage down to which folders are
consuming it, crash and system logs, login items and launch agents,
network configuration, and permissions. From that it identifies the likely
cause, proposes one specific repair, shows it to you before anything
happens, and carries it out once you approve.
Noah shows the proposed repair before making changes, and repairs are
designed to be reversible — files it clears go to the Trash rather than
being erased. Every command it runs is checked against a safety policy
first, and anything that policy judges riskier is shown to you as the
exact command and waits for your approval.
What Noah fixes on a Mac
- A slow Mac — beachballing, laggy apps, everything taking too long
- Overheating and loud fans — one process pinning the CPU
- Runaway system processes — WindowServer, mds_stores, kernel_task, bird
- Storage full when your own files don't add up — including “System Data”
- Memory pressure and gigabytes of swap
- Wi-Fi that drops, or connects with no internet
- Apps that crash or won't open — Safari, Chrome, Mail, Adobe after an update
- Battery draining fast, or a Mac that wakes from sleep by itself
- Mic, camera, or audio not working in Zoom or Teams
- Files that won't sync — iCloud Drive, Dropbox, OneDrive stuck
Noah is not a hardware repair service. For physical damage or failing
components, use Apple or a repair provider. Noah handles software,
configuration, performance, network, app, sync, and system-health issues —
and tells you plainly when a problem is hardware, so you stop spending
evenings on something a Genius Bar appointment will fix.
What Noah can inspect, and what it can change
Noah reads: processes and resource use, memory and swap, disk and
folder sizes, crash reports and system logs, login items and launch
agents, network configuration and DNS, app and system permissions,
installed applications, and update state.
Noah changes only what you approve, one step at a time: quitting or
disabling a misbehaving process or login item, clearing caches and
recoverable space to the Trash, resetting a network configuration,
repairing a permission, or removing an app and its leftovers. Anything
consequential asks again before it runs.
Will it run on my Mac?
Noah runs on macOS 12 (Monterey) and later, on both Apple Silicon
(M-series) and Intel Macs — MacBook Air, MacBook Pro, iMac, Mac mini, Mac
Studio and Mac Pro. It is notarized by Apple. Free to start; nothing is
charged until you choose to pay. Noah for Windows is at
onnoah.app/windows/.
Questions
What does Noah actually do?
Noah takes the frustration out of using your Mac. You tell Noah what's wrong
in plain words; it investigates like a technician, works out what's really
causing it, and comes up with a plan. Once you approve, Noah carries it out
— and your Mac is back to itself.
Can an AI actually inspect my Mac, or does it just give advice?
It inspects. That is the difference between Noah and a chatbot. ChatGPT can
only work from what you type into it, so the best it can do is hand you
Terminal commands and ask you to interpret the output. Noah reads the
machine's own state directly — running processes, memory pressure and swap,
disk usage, crash logs, login items and launch agents, network
configuration, permissions — then names the likely cause and proposes one
specific repair.
Do I need to be good with computers to use it?
Not at all — that's the whole point. You describe the problem the way you'd
tell a friend (“it's slow,” “it keeps crashing”), and Noah handles the
technical part. You never open Terminal, and there is nothing to configure.
How do I know Noah won't break my Mac?
Noah shows you the plan in plain English before it acts. Every command it runs
is checked against a safety policy first: diagnostic checks run on their own,
and anything the policy judges riskier is shown to you as the exact command
and waits for your approval — you can refuse, and people do. Files it clears
go to the Trash rather than being erased, so you can put them back, and every
change is recorded in the Action Log. It's built to be cautious, not clever.
Does Noah spy on me, or read my personal files?
No. Noah reads your Mac's diagnostic state — the kind of thing a repair
technician checks. It also checks file and folder sizes to find what's
filling your disk. It doesn't look inside your documents or photos, never
uploads your files, and can't see your browser history, passwords, or
screen. Nothing is moved or deleted without your OK.
Is Noah safe, or one of those scammy “cleaner” apps?
Fair question — the Mac world is full of those. Noah is the opposite: it
never scares you into paying, never nags, and never removes anything without
showing you first and asking. It is notarized by Apple, and a real person —
Eric, who built it — is an email away at hello@onnoah.app.
How is this different from EtreCheck, Activity Monitor, or Apple Diagnostics?
Those tell you what is happening; none of them fix it. Activity Monitor
shows you a process using 90% of the CPU without saying whether that is
normal or what to do. EtreCheck produces a long report you then have to
interpret. Apple Diagnostics only tests hardware, so a software problem
comes back “no issues found.” Noah reads the same state those tools expose,
tells you the cause in plain English, and then carries out the repair with
your approval.
What does Noah cost?
Free to download, the diagnosis is always free, and so are your first few
fixes. You only start paying for the complicated repairs — the ones that
would otherwise cost you an afternoon or a trip to the Genius Bar. When you
get there it's one question, two weeks or a year: Noah Pass — $29 gives you
everything Noah can fix for 14 days, as often as you need (fixed or your
money back), and then it simply ends — it does not renew. Noah Guardian —
$79/year is the same thing for a whole year, plus Noah checking in on its
own, and it renews each year until you cancel. Cancel anytime from Settings,
or just email us.
What if I get stuck or need help?
A real person reads every Noah message. Email hello@onnoah.app and you'll usually hear
back within a few hours. Noah isn't a faceless lab — it's made with love in
the U.S. Midwest.
Will Noah fix a hardware problem like a swollen battery or a failing SSD?
No. Noah diagnoses the symptom and tells you when it's hardware, so you know
whether to book a Genius Bar appointment instead of spending another evening
on it. Repairing physical parts isn't its job.
Does Noah work on Windows?
Yes — there's a dedicated build at onnoah.app/windows/. Same
conversation model and Action Log; the diagnostic tools differ to match what
each operating system exposes.
