Atomic▲106Hey 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…

Atomic▲140Hey HN, I’ve been building Atom (https://github.com/rush86999/atom), an open-source, self-hosted AI automation platform. I built this because while tools like OpenClaw are excellent for one-off scripts and personal tasks, I found them difficult to use for complex business workflows (e.g., managing invoices or SaaS ops). The main issue was State Blindness: the agent would fire a command and assume it worked, without "seeing" if the UI or state actually updated. I just shipped a new architecture to solve this called Canvas AI Accessibility. The Technical Concept: Instead of…

Hi HN, I’m an indie developer building Chemistry AI – a web-based chemistry solver for high-school and college students. Motivation: I saw many students searching for “chemistry AI” and mostly getting generic chatbots or math tools. I wanted something focused on chemistry that actually explains the steps, not just the final answer. What it does: - You can type a question or upload a photo of a worksheet. - The AI reads the problem and shows transparent, step-by-step reasoning. - It covers topics like equations, stoichiometry, acids/bases, equilibrium, thermodynamics, and basic organic…
