    In the last few years I've been doing a lot of technical writing, both for my own programming blog and others, and I've noticed there is a lack of good tools for this kind of writing. Whether that was a programming blog post or documentation, I always had to move back an forth between different editors, and sometimes even other apps for content management and the actual content publication. A lot of copy-pasting, and wasted time. Based on this experience I decided to try and build a tool that could provide a good experience for this kind of content from writing to publishing. This (I call it…

    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…

    I'm excited to finally launch Outstatic, an open source static website CMS that doesn't require a complicated setup or signing up to a third-party service! You can access the documentation here: Outstatic Documentation. I invite you to start by deploying our example blog to Vercel and giving it a try. I think you'll be pleasantly surprised at how easy and fun it is to use Outstatic. Please, let me know what you think. This is the first public version of the project and all feedback is welcome. If you dig the project feel free to leave a star on Github. I appreciate your support!

    Hey HN! We're building an open-source CMS designed to help creators with every part of the content production pipeline. We're showing our tiny first step: A tool designed to take in a Twitter username and produce an "identity card" based on it. We expect to use an approach similar to [Constitutional AI] with an explicit focus on repeatability, testability, and verification of an "identity card." We think this approach could be used to create finetuning examples for training changes, or serve as inference time insight for LLMs, or most likely a combination of the two. The tooling we're…
