HyperKnowledge 3000: Keep your AI chats, notes, and files together in one workflow

Hey everyone!
I'm part of the team behind HyperKnowledge 3000 (HK3K), not on the dev side, but I use it daily and wanted to share it with a community that would actually get what it's trying to do.

The core problem it solves: AI tools are powerful, but they don't know you. Every session starts from scratch. HK3K fixes that by connecting to your Notion workspace and importing your past AI conversations so your searches are grounded in your own knowledge, not just the internet.

The full feature set just went live:

Personalized AI Search answers that factor in your Notion workspace and conversation history

Chrome Web Store - HyperKnowledge 3000

Your AI-powered second brain. Capture knowledge, search with AI, connect to Notion.

We tried to fix the “scattered notes” problem - this is what worked

Before anything else, a bit of context:

We re building an AI tool that helps you search and use your notes (Notion, docs, etc.) without digging through everything manually. The idea made sense but when people actually used it, it didn t really stick. So we stopped pushing it and went back to fix what wasn t working. We didn t want to relaunch without seeing real improvement.

New here -- Hi PH! AI enthusiast working on second-brain productivity tools

Good day everyone!

I'm Gretchen, an AI enthusiast and part of a small team working on productivity tools around the idea of a "second brain." Lately we've been exploring ways to make AI chats and knowledge easier to organize and search.. especially as conversations with tools like ChatGPT start piling up. I'm here to learn from other makers, share what we're working on, and hopefully get feedback from people who care about productivity and AI workflows. Looking forward to connecting with everyone here!
