The Great Filter
Peace of mind for your piece of mind.
The internet didn't used to be this way. The Great Filter is a Chrome extension that intercepts your social media feed before it reaches you and filters harmful posts and comments such as outrage, scams, harassment, and manipulation in real time. X, Reddit, YouTube, and Bluesky is working now. Extension already available for download.
I built this because I needed it.
Late one night, already exhausted, I stumbled into someone's grief journey on social media. I sobbed over a stranger's loss. A cathartic cry, I told myself. Then the next night it happened again. A dead child this time. Worse, because I thought of my own kids sleeping in the next room.
I tried to fix it the normal way — telling the algorithm I didn't want this content. That worked for a few days, but the algorithm must flow and things changed. For a week it gave me get-rich-quick schemes. Then political rage bait. I just wanted something interesting to read. Instead the platform was feeding me one of the seven deadly sins every night in the name of engagement.
The internet shouldn't work this way.
So I built The Great Filter.
It sits between you and your social media feed, evaluating each post before it reaches you using Claude AI. Outrage farming, financial scams, harassment, psychological manipulation — filtered before you see them. Each filtered post shows you exactly why it was removed. You can always click "View anyway." You're never locked out of anything.
What's working today:
X / Twitter — full feed filtering
Reddit — posts and comments
YouTube — comments
BlueSky — full feed filtering
Three modes:
Open — only the worst removed
Curated — outrage and manipulation filtered out
Quiet — aggressive filtering for the days when you've chosen peace
Privacy by design: Post content is evaluated and immediately discarded. We never store what you read. We never log filter verdicts. We never build a profile of your behavior. The only things we know about you: your email address and how many evaluations you've used this month.
Free to start: 200 evaluations/month with no credit card required. Unlimited with a subscription.
The name comes from the Fermi Paradox: the Great Filter is the theory explaining why we seem to be alone in the universe. The internet was supposed to connect us. It's been driving us further apart or worse - driving us away from ourselves as we spiral down into unhealthy places fed to us by a moment of engagement on one single post. I think we just need something to filter out the garbage.
Happy to answer any questions. And if you've had a bad night on social media that sent you somewhere dark — this was built for you.
