Portals▲128I'm building a workspace for doing focus work while also managing constant multi-tasking and context-switching that's required in a lot of roles. Currently this is done by using a notes system where we can split-screen AI chat, an object-based data table system for tracking entities, as well as viewing other documents. We can define agents directly from documents by giving instructions in plain language and then defining the trigger conditions. This helps automate workflows directly in the place where we're reading and writing content. I'm continuing to experiment with instructions and…

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. So we took a different approach. In doXmind, AI works directly in the document instead of living in a sidebar chat. It reads the structure of what you’re…

When I do real research — reading papers, books, or trying to understand a complex topic — it never happens in one sitting. I explore a bit, get interrupted, come back days later, ask new questions, find new sources, and gradually build understanding. Existing AI tools are great at answering questions once, but they reset context every time. Notes tools preserve text, but not understanding — they don’t help me reconnect ideas, revisit sources, or see how my thinking has evolved. I built Kerns to sit in between. Kerns is an AI research workspace designed for research that unfolds over time.…
