Koi.rest is an animated pond — each fish on screen is another visitor sitting with you right now, no chat, no profiles, just shared quiet. There’s ambient sound you can mute and a timer (10, 15, 30, 60 minutes, or custom) if you want the visit to end on its own. Its creator, Paul Glushak, built it solo with AI assistance and calls it simply “a quiet place to regain your balance.”
