Second Brain▲302Hi 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.…

Hey HN -- I'm Shalin, one of the cofounders of Hyper. My cofounder Kanyes and I have been power users of a lot of second brain type software like Notion and Obsidian for years, and tried fine-tuning GPT-2 back in 2020 to solve this exact problem of giving AI access to all context of my life so it can do work for me more intelligently. We were too early then, and spent the next 4 years building robots at Matic. Earlier this year, we realized this was perhaps the right time to take a second crack at this problem, so we quit our jobs and built Hyper. It's super exciting that we finally shipped…

FlowTask 2.0▲138For years, I was stuck. Trapped in a loop. Every new project, every team initiative – it began with the same soul-crushing setup. Hours. Gone. Not on the actual work, mind you. But on the meta-work. Defining tasks. Sketching forms. Mapping workflows. Hunting for that 'perfect' template that never quite fit. Just trying to get to zero. To a starting line where meaningful work could actually begin. Most project management tools? They're brilliant once things are up and running. Tracking, collaborating, reporting – they nail it. But that initial blank canvas? That moment you’re staring at an…
