zymum.com - minimalistic ai note enricher

I built Zymum because I was tired of losing links and notes I knew I'd saved "somewhere." Notion, WhatsApp, browser bookmarks... the problem isn't saving, it's finding later. Zymum processes everything you save (links, PDFs, tweets, YouTube videos) with AI, extracts key entities and concepts, and lets you chat with your entire knowledge base. Ask a question, get an answer with sources. A second brain that actually remembers where it put things.
