A developer has created "HNRelevant," a browser extension that adds a "related" section to Hacker News posts, helping users discover similar discussions or articles. The project is open for feedback and discussion on the platform.

Editor’s Note: If you're a regular Hacker News reader, this could make your browsing experience smoother by surfacing relevant threads you might otherwise miss. It’s a small but clever tweak—exactly the kind of thing the HN community loves to build and share. Plus, it’s open for collaboration, so developers might jump in to refine it further.

A tool called Mermaid is making waves by letting users generate professional-looking diagrams—like flowcharts or sequence diagrams—just by typing plain text. Think of it as a quick way to turn your rough ideas into polished visuals without fiddling with design tools. The discussion around it highlights how it could save time for developers, educators, or anyone who needs to sketch out processes.

Editor’s Note: Visualizing complex ideas is a pain point for a lot of people, whether you're mapping a software workflow or explaining a concept in a meeting. Mermaid cuts out the manual labor, making it easier to communicate clearly—which is always a win. If it catches on, it could become a go-to for streamlining documentation and brainstorming.
