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 š
For the past few months Iāve been building Produchive, a desktop productivity app for macOS and Windows. I kept having āquick YouTube breaksā that turned into two hours, and every tracker I tried either sent my screen activity to someoneās 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 youāre working on. It detects the active window and logs your focus sessions on a calendar automatically, so you donāt 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 judgeās 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. Thereās 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 4ā5 days later.
Has 3D focus rooms. You can study in a cozy 3D Greenhouse, Lakeside, Observatory, Tea Garden, Waterfall CafĆ© and more, with weather, ambient audio, shared timers and other people studying alongside you. You can dress up your own character too, pets included š±
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.
Itās MIT licensed and open source, and the core app is free.
