AI Brother is Watching You
Your Orwellian focus guardian for the distracted internet.
What it does
Tell Big Brother AI your focus goal—like “Do user research”—and it silently watches every tab. ✅ On-topic? Carry on. ❌ Off-topic? Blocked. No more cat videos when you’re studying math. No algorithmic rabbit holes. Just pure, focused work.

- ISI struggle to focus working from home so I built a solution2023 · ▲31
Hey HN friends, I keep getting distracted working from home and always end up watching youtube, browsing blogs like HN or just mindlessly scrolling then I feel like crap because I didn’t do enough. I went through dozens of productivity tools but they’re quite overwhelming to use and none of them actually helped me focus. So I built http://complish.ai, a web-based sidebar that helps me focus on one task at a time. I launched it last month and have over 3,000 users now and I’ll be keeping it free. Would love for you all to try and give some feedback!

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
