NodeLand▲533Hello, HN! Have you ever considered that you might be a visual thinker? A lot of studies emphasize the benefits of visual thinking in learning, as it activates different parts of the brain and enhances comprehension and retention. It is common, for example, to remind yourself of a concept by visualizing the page where you wrote it down. This is because the brain is more likely to remember visual information than text. Unlike traditional linear note-taking apps like Notion and Evernote, NodeLand introduces a revolutionary connection-based model. Everything you write is seamlessly integrated…

doXmind▲108Hi HN, I’m Steve, co-founder of doXmind. We built doXmind for people who want docs and AI, but not all of Notion. Notion is powerful, but if your main use case is writing, collaboration, and AI help inside documents, it can feel like more than you actually need. You end up inside a much bigger workspace of databases, templates, and project management features, when sometimes all you really want is a clean doc editor with strong AI built in.

Hey HN, author here. I noticed a pattern: every time I asked my AI assistant a complex question like "should we migrate to microservices or optimize the monolith?", I'd get the same generic pros-and-cons list. The model has the reasoning capability — it just lacks structured mental models. So I built Think Better: a set of open-source "AI Skills" (following the Anthropic skill format) that inject professional decision science frameworks directly into your local AI setup. How it works under the hood: - The skills contain 16 CSV files with 155 structured knowledge records (decision frameworks,…
