What it does
I built Dual N Back because I wanted a simple way to train my working memory and see whether I was actually improving. Most trainers I tried felt outdated, repetitive, or showed too little progress data. So I created a free web-based trainer with adaptive difficulty, detailed analytics, customizable sessions, daily goals, and reminders. No installation required. The product is still evolving, and I’d love your feedback.
Use Dual N Back for daily training. The scientifically proven method will help you develop working memory and increase attention concentration completely free of charge.
The time you can stay undistracted and be in focus on one specific task. The trainer allows you to get rid of clutter in your head and structure your thoughts. Simultaneously follow the sound and position of the square, keeping focus on two channels. Compare the current signal with the one that was 2–3 steps ago, constantly updating data in memory. If a complex task causes procrastination, a short session on the trainer will "warm up" the brain and help quickly enter the state of focus. The trainer teaches you to keep several details in mind at the same time, without mixing them up and without losing the thread of the main task. Helps not to "head in the clouds" during learning or prolonged…from dualnbackapp.com

Second Brain2025 · second-brain-lac-ten.vercel.app · ▲281Hi HN, I'm Dom, a solo founder. I built Second Brain to solve a common issue I had with AI chats: the knowledge disappears. There’s no structure, no memory, and no way to reuse or build on them. So I built a tool that combines AI chat with a visual, interconnected knowledge system. Key features: - Save AI responses into editable docs (Notion-style Pages). - AI Visual board with multiple content & chat nodes (like Miro meets ChatGPT). - Add and chat with YouTubes, TikToks, Audio, PDFs, GitHub repos, Looms, websites, etc. - Organize using Projects and Smart Tags — then chat with full contexts.…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
