Guard your wellbeing.
Stay in control of
your AI use.
Guardian runs in your browser and tracks how much time you spend with AI tools. When a session goes too long, it checks in. Your call.
Why Guardian exists
AI tools are designed to extend your sessions.
Guardian is designed to protect you from that.
The average knowledge worker spends hours a day in AI sessions. Most have no idea how many. Guardian tracks every session — duration, frequency, topic patterns — and shows that data privately, just for you.
When the numbers suggest you need a moment, Guardian checks in.
How Guardian works
Three things.
Tracks your sessions automatically
Duration, frequency, how many messages you've sent. Guardian runs in the background on Claude, ChatGPT, Gemini, and more.
Set to your normal
Guardian asks you ten questions once during setup. Your answers set a personal baseline. Check-ins fire against your patterns, not a generic threshold.
A check-in at the right moment
When a session runs long or your day looks heavy, Guardian checks in. You decide what to do.
Your usage, visible
See how much AI you're actually using.
Session duration, frequency, and what you were talking about. Guardian shows you a complete view of your day — data you were generating anyway. Now you can see it.
Most people are surprised by the numbers. Guardian makes them available in a dashboard, updated in real time, stored only on your device.
"I thought I was quickly checking something. Guardian showed me I'd had eleven sessions that day. I didn't realise how much of my thinking I'd outsourced."
— Early user, knowledge worker
Built around you
Your check-ins are set to you, not a default.
You define what a heavy day looks like. Guardian works from that. Answer ten questions once. Guardian checks in when your day looks unusual for you.
The assessment uses the CAIDS-10, a short form of a published clinical instrument. Two minutes, done once. Your responses stay on your device.
Built differently
Your mind is private.
So is your data.
Guardian has no server. Everything Guardian stores lives in your browser's local storage and nowhere else.
Stays on your device
All stored locally. We have no server to send your data to.
No account required.
Install it and it works.
Yours to take
Export everything as JSON or CSV. Delete everything with one click. Your data stays yours.
