Does errorboard record everything on my screen?
No. It only ever captures the foreground window, and only when
that window belongs to an app on your allow-list and sits on a monitor you've chosen
to watch. Anything else — email, messaging, the desktop, a window on an excluded screen — is
never captured.
Where does my data go?
On the free tier, screenshots are sent only to your own NVIDIA NIM
endpoint using your key, and the error logs are plain Word files saved in your
Documents folder. Nothing is stored on our servers. On errorboard Pro, detection runs in the
cloud and your logs sync to your account so you can study across devices.
Do I need an NVIDIA key?
For the free app: yes — you bring your own NVIDIA NIM key (free to
get at
build.nvidia.com).
errorboard Pro runs the model for you, so no key is needed.
What counts as a "mistake"?
A visible academic error in your work — a wrong answer on a practice problem,
an incorrect calculation, a flawed step of reasoning, a bug in code, or a wrong factual
statement. errorboard is deliberately conservative: it only logs flags it's actually confident
about, and you can tune that threshold in settings.
Will it slow down my computer?
It's light. errorboard samples the screen on an interval (default every ~12s) and
only calls the model when the window has actually changed, so an idle screen costs nothing. It
lives in the system tray with no visible window.
Can I use it on more than one device?
The app itself runs on any number of your Windows machines. With errorboard Pro,
your error logs sync across all of them under one account.
How do I cancel my subscription?
Sign in, open your
account, and choose
Manage billing — that opens the Stripe customer portal where you can cancel or change
plans any time. Access continues until the end of the period you've paid for.
Windows warns me when I open it — is that normal?
Yes. errorboard is a new independent app and isn't code-signed yet, so Windows
SmartScreen may show an "unknown publisher" notice. Choose More info → Run anyway. Signing
to remove the warning is on the roadmap.
Which platforms are supported?
errorboard is Windows 10 and 11 (64-bit) today. The capture engine is built on
Windows-specific APIs; other platforms aren't supported yet.
