Hawser: an Opal Alternative Built for Your Computer

Short answer: Opal is a beautiful, polished focus app, but it lives on your phone and runs on focus sessions you schedule in advance. Hawser is for the other half of your day: the hours of real work that happen on a computer. It runs on Windows, and instead of waiting for a timer you set this morning, an AI watches your screen, notices the moment you drift off the task you set for the day, and nudges you back with a friendly check in. If your distraction problem lives on your laptop, not your phone, Hawser is the alternative built for you.

The real difference: a schedule versus the moment

Opal does its job beautifully. It is mobile first, the design is genuinely lovely, and its screen time controls and gamified stats make it one of the best ways to put your phone down. If the thing pulling you away is your phone, Opal is hard to beat.

But Opal runs on focus sessions you set in advance. You decide this morning that from 9 to 11 these apps are off limits, and it holds you to that plan. The trouble is that real work does not always match the plan you made over coffee. You finish early, you start late, the important thing today is not the thing you blocked yesterday.

Hawser takes a different path. It runs quietly on your computer, and instead of enforcing a schedule, it reacts to what you are actually doing right now. The moment it sees you slip off the one thing you said mattered today, it does not run down a timer. It checks in: "Hey, I noticed you wandered off. Want to get back to it?" A blocker can't tell a 10-hour work day from a 10-hour binge. Hawser can.

Why I built this

I never used Cold Turkey itself, but I lived on the hard blockers it represents, the kind that just lock you out or boot you off your computer once you have used something "too long." They drove me up the wall, because my life does not run on a fixed schedule. One day I am heads down working for ten hours straight. The next, I might sink ten hours into a video game, and that is completely fine. A rigid blocker cannot tell those two days apart. It enforces the same dumb rule and kicks me off either way, usually on the day I needed it least.

That is the whole reason Hawser exists. It does not run on an arbitrary timer that has no idea what your day actually looks like. It works off what you set out to do, so ten hours of real work is never treated like the enemy, and it only steps in when you have genuinely drifted from it. It adapts to your day instead of fighting it.
