MindStruct turns messy thoughts into linked concepts, next actions, and a living knowledge graph you can actually use. Capture meeting notes, research, transcripts, or a fast brain dump. MindStruct uses private on-device intelligence to structure what you wrote, surface open loops, and help you move from raw thought to clear action. MindStruct has been redesigned around the workflow that matters most: capture messy input, turn it into trusted context, and return to the right next move when it counts. This update makes MindStruct feel less like a blank notes app and more like a private memory system for people who live inside complex context: researchers, writers, consultants, advisors, founders, and operators. What's new: A clearer Capture flow Drop in notes, meeting debris, transcripts, links, imports, scans, and rough thoughts. MindStruct now helps organize incoming material before it becomes a brief, so you can decide what deserves attention before it piles up. Reviewable AI briefs New capture review surfaces make it easier to see what MindStruct found: key ideas, concrete next steps, source-backed evidence, uncertainty, and where each item should go next. Useful context becomes memory only after review. A smarter daily Brief The Brief tab now brings together open loops, recent context, approved memory, upcoming prep, and the next action that deserves focus. It is built for the moment before a call, planning session, or writing sprint. A richer knowledge Map MindStruct's map is now more useful for real work. See ideas, actions, clusters, relationships, emerging themes, and connections that need review. Ask the map what matters, inspect why links exist, and keep your knowledge base from turning into another pile. Better follow-through Turn important next steps into reminders, track what is scheduled, mark actions complete, and reopen the context behind the work. MindStruct helps protect commitments without replacing your task manager. More ways to capture Send text, links, and files into MindStruct from other apps. Import Markdown, text, HTML, and rich text sources. Scan images for useful text. Pro users can also bring in video material for recall and prep. Vault and Markdown workflows Connect a Markdown or Obsidian-style vault, import existing notes, and keep external knowledge flowing into your private memory system. MindStruct can help turn old notes into live context instead of archived clutter. Personalized work modes Choose the workflow that fits your world: Client Prep, Research Synthesis, Operator Review, Session Reflection, Evidence Log, or Household Memory. Each mode tunes capture around the kind of clarity you need. Faster return paths Widgets, Spotlight search, and Shortcuts now make it easier to reopen the exact idea, next step, planning memory, capture queue, map, or brief when it is useful. Use MindStruct to: - Turn raw notes into linked concepts and action items - See ideas, relationships, and unfinished loops in a live knowledge graph - Generate grounded daily plans from your actual graph and upcoming commitments - Create concise meeting briefings from calendar context - Export clean Markdown to your vault - Keep control with privacy-first toggles for calendar, contacts, and location MindStruct is built for founders, researchers, students, product teams, and anyone building a more useful personal knowledge system. Apple Intelligence features require a compatible device and supported system configuration. https://sites.google.com/view/spaceplantcorporationapps/home https://sites.google.com/view/spaceplantcorporationeula/home
