Hey Product Hunt 👋 I built Mentro because every Pomodoro timer I tried lost to a single tab. The timer would keep counting down in the background while I read something unrelated for twenty minutes - technically a "focus session", practically nothing. So I made the timer notice. Mentro sits in Chrome or Edge with an animated companion that reacts the moment a tab doesn't match what you said you'd work on: it speaks up, blocks the tab, groups the rest by task, and calls you back when the break is over. The part that took longest wasn't the blocking - it was making the companion feel like company instead of a nag. Too quiet and you ignore it, too loud and you uninstall it on day two. Most of the work went into that line. Free forever with three companions, no ads or trackers. Premium is $1.99/month for the full cast. I'd love to hear what actually breaks your focus - I'm curious whether tab drift is the main one for you too, or something else entirely.
