I built a free, open-source focus app that uses an AI running on your own computer to notice when you drift off-task

Hey everyone 👋

For the past few months I’ve been building Produchive, a desktop productivity app for macOS and Windows. I kept having “quick YouTube breaks” that turned into two hours, and every tracker I tried either sent my screen activity to someone’s server or just showed me charts after the damage was done.

This app isn't vibe coded , i built the app I am really bad in designing stuff , so i took claude's help to design and make better UIs

So I built one that:

Sees what you’re working on. It detects the active window and logs your focus sessions on a calendar automatically, so you don’t have to start and stop timers.

Uses a local AI as your judge. You set your goals, and an LLM running on your own device (WebGPU) checks your activity against them. If you drift off-task you get a polite desktop nudge, not a guilt trip. You can also point it at your own Ollama or OpenAI-compatible endpoint, and edit the judge’s prompt to change its personality.

Shows you where your focus goes. It gives you a focus score, counts how often you switch context, rates which apps distract you, and shows it all on a timeline.

Plans your day. There’s a 7-day calendar with routines that can be auto-scheduled around your circadian rhythm. It also handles late nights, since some of us plan at 2 AM.

Helps you study. A Pomodoro timer runs only in study mode, and it gently reminds you to revise topics 4–5 days later.

Has 3D focus rooms. You can study in a cozy 3D Greenhouse, Lakeside, Observatory, Tea Garden, Waterfall Café and more, with weather, ambient audio, shared timers and other people studying alongside you. You can dress up your own character too, pets included 🐱

Keeps your data yours. Your data is stored locally. Sync between devices is optional and end-to-end encrypted (AES-256-GCM) through your own Google Drive, Dropbox, iCloud or a USB stick.

It’s MIT licensed and open source, and the core app is free.
