OpenKnowledge – open source AI-first alternative to Obsidian/Notion▲381
Hi HN, Nick here. We’re launching OpenKnowledge (https://openknowledge.ai/), a “what you see is what you get” markdown editor that has direct integrations with Claude, Codex, and other agents. Available as MacOS app or Web UI+CLI. Fully free/local and OSS. We built this because we wanted a Notion-like experience for writing and sharing markdown files across our team. Obsidian is the best alternative we tried, but found it doesn’t have a true WYSWIG UI and it didn’t integrate well with Claude/Codex outside of community plugins. So we built OpenKnowledge. It takes…

LightPaper for Mac – Free Markdown editor▲132
I'm not the author of the app (nor i have any connection with them, just a random user). iA Writer and Writer Pro aren't well suited for me as a developer. They feel quite "strange" to me.
