    Hey HN - I first posted about my knowledge base product, Atomic, here around a month ago; since then, a viral tweet by Karpathy has produced a torrent of AI powered knowledge base projects. meanwhile I've been shipping like crazy, here are some of the new features shipped in the last month: - Rebuilt the iOS app with an Android app on the way - expanded both the MCP and internal agent chat toolkit immensely - A custom, CodeMirror6-based markdown editor with obsidian-style rendering - A dashboard view that provides a daily summary of atoms created or updated in the last day And many bug fixes…
