What Noah can actually fix
This is the whole list, and it is the same on every plan — Noah has no locked features. Free, Monthly and Guardian differ in how long Noah stays on call, never in what it can do.
Most tools of this kind publish a list that grows with the price. Noah's does not, because there is nothing to unlock: the same diagnosis and the same repairs are available on the free first conversation and on Guardian. What you pay for is Noah still being there next week.
Everything below is pinned to a real tool in the shipping app, and the page fails to build if one of them is removed. The last section is the part that matters most: what Noah cannot do.
It's slow, stalling, or spinning
The most common thing people arrive with, and the one where naming the cause matters most — "your Mac is slow" is not an answer, and neither is a cleanup that removes something unrelated.
What Noah checks- Take a performance reading and judge it against the machine's own headroom, rather than against a number from a spec sheet
- List what is actually running and what each process is taking, so the cause has a name
- Read the machine's specification and current state — model, memory, storage, how long it has been up
- Quit the process that is taking the machine, once you approve it by name
- Clear system caches that have grown into the problem
It takes forever to start up
Usually a list nobody has looked at in three years: things that were given permission to launch at login once and never asked again.
What Noah checks- List everything set to launch when you log in, including the ones with no visible window
- Stop a login item from launching — and turn it back on later if you miss it
The disk is full
Noah shows you where the space went before it proposes removing anything, and it never removes something you have not seen named.
What Noah checks- Measure where the space actually went, folder by folder
- Clear caches — system-wide, or one badly behaved app's
- Move a named file to the Trash, where you can put it backMac onlyOn Windows, Noah moves the file to a folder you choose instead — it has no Recycle Bin tool, so it will not claim one.
- Move a file somewhere else, to a folder you choose
- Stage a removal you can reverse, so nothing is gone until you say soMac onlyOn Windows, Noah moves the file instead — there is no staged removal there.
Wi-Fi drops, or you're connected with no internet
Two different faults with the same symptom. Noah's job here is mostly to say WHERE the chain breaks — the router, the name lookup, or the connection past it — because that decides who fixes it.
What Noah checks- Read the network settings in effect, and test the route out step by step
- Check whether name lookups are resolving, which is what "connected but nothing loads" usually is
- Look at the Wi-Fi networks in range and how the signal actually readsMac onlyWindows has no scan tool in Noah; the checks above still run.
- Flush the name-lookup cache when it is holding a stale answer
Flushing the cache is the only change Noah makes to your network. It does not reconfigure your router, your adapter or your DNS servers — it tells you what it found and leaves that to you.
An app keeps crashing, hanging, or won't open
The one class where the machine has already written down what happened. Noah goes and reads it instead of guessing from the symptom.
What Noah checks- Read the app's own logs and the crash reports it left behind
- List what is installed, and look at the support files an app keeps beside itself
- List browser extensions, which are a common cause of a browser that has become unusableMac onlyOn Windows, Noah reads the browser's own logs instead; it cannot enumerate the extensions.
- Clear one app's cache, which is what a surprising number of "won't open" faults are
- Force-quit an app that has stopped responding
- Uninstall an app properly, or stage its removal so it can be put backMac onlyOn Windows, Noah walks you through Windows' own uninstaller rather than claiming to do it for you.
Printing has stopped working
Almost always a stuck queue or a stalled print service, and almost never the printer — which is why it is worth checking before anyone buys a cable.
What Noah checks- List the printers the machine knows about and what is sitting in the queue
- Cancel the jobs that are jammed at the front of the queue
- Restart the printing service itself
A Windows service has stopped
Windows keeps a lot of the machine's real work in services, and one of them stopping looks to you like an unrelated feature breaking.
What Noah checks- List the services and their stateWindows onlymacOS has no equivalent Noah tool — the closest reading on a Mac is the process list above.
- Restart a named serviceWindows onlyNoah has no service restart on macOS — the nearest fix there is quitting the process and letting macOS start it again.
Something happened and you want to know what
Shutdowns that nobody asked for, an error that flashed past, a change you did not make. The machine keeps records of this and they are hard to read on purpose.
What Noah checks- Search the system log for the window when it happened
- Read a specific file or report the system has written
This family is read-only by design. Noah tells you what the records say; it does not change anything to make them say something else.
What Noah does not do
Every list like this one is written to look complete. Here is the floor under ours.
- Noah does not read temperatures or fan speeds. There is no sensor read on either platform — what it can tell you is when macOS is throttling the processor, which is a consequence of heat and of several other things.
- Noah does not measure what each app is taking from the graphics card. The performance reading covers the processor and memory.
- Noah does not watch your machine in the background. It runs when you open it and ask it something — there are no scheduled scans, no health checks while you are away, and no alerts.
- Noah does not recover data from a failing drive, and it does not repair hardware. It can tell you what the machine reports about the fault, which is often the thing that decides whether it is worth a repair at all.
- Noah does not make a change you have not seen. Every action that alters the machine is shown to you first, in the words of what it will do, and does not run until you approve it.
The same list on every plan. Noah has no locked capabilities and no "advanced" tier — the free first conversation reaches every repair above. What a plan buys is Noah still being on call afterwards.
Tell Noah what's wrong
Finding out what's wrong is free, every time. Your first conversation is free with fixes included.
Questions
Does the free version fix less than the paid one?
No. There are no locked capabilities. Your first conversation is free with fixes included, and after that running a fix needs a plan — but it is the same fix, from the same list.
Does Noah monitor my computer in the background?
No. Noah runs when you open it and ask it something. There are no scheduled scans and no alerts.
Will Noah change something without asking?
No. Every change is shown to you before it runs, described in terms of what it will do, and waits for your approval.
Is the Windows version the same as the Mac one?
Mostly, and where it is not, the list above says so. Windows has services that macOS does not; macOS has a Trash tool and a Wi-Fi scan that Windows does not.
