stoa doesn't just block distracting sites — it asks you to justify yourself. That conversation is what changes behaviour.

Freedom. Cold Turkey. LeechBlock. You've probably tried at least one. Maybe all three. They all have the same fatal flaw.
When the craving hits — and it does, hard — you just turn them off. Willpower can't compete with a dopamine loop.
Traditional blockers assume the problem is access. It isn't. The problem is the moment of impulse. The five seconds between boredom and a tab full of distractions.
"The act of explaining yourself is what creates behaviour change — not the block itself."
Hey — you've tried to open YouTube 3 times today. What's going on? What do you actually need right now?
I just need a 5 minute break, I've been working for 3 hours straight.
That's fair. A break sounds genuinely needed. What kind of break would actually help — a walk, music, or do you really want to scroll?
...honestly a walk would probably be better.
No complex setup, no timers, no guilt. Just a gentle check-in that puts you back in charge.
Add any distracting website — social media, news, streaming — and set how strict you want stoa to be: Lenient, Balanced, or Strict.
When you visit that site, stoa opens a conversation — not a hard block. The AI asks why you want access. Right now. You can't skip it.
Most people discover mid-conversation they don't actually need it. If you do, the AI grants temporary access — and remembers for next time.
Every feature is designed to make self-awareness effortless — not to shame you into compliance.
An AI that asks the right questions — not to judge you, but to help you hear yourself think. Rooted in the Socratic method and conscientisation.
Three modes — Lenient, Balanced, Strict — so you can dial in the right level of friction for each site and each season of your life.
Every negotiation is saved. Review your patterns, see what reasons you keep giving, and notice when the same excuse comes up for the fourth time.
The AI learns your patterns and gets smarter about your habits — calling out when your reason today sounds a lot like your reason yesterday.
