Organize your knowledge through mind mapping and create your personal mind library. Instead of carving knowledge into your brain’s neurons by repeating it over and over, why not persist it as a mind map in an information network? Only once and without the risk of losing it. Starting from a central node, mindlib enables you to save, relate, and compare information. Knowledge is displayed in a mind map-like style, where everything is interconnectable—just like your mind. Engage in dynamic conversations with your personal AI to explore, refine, and expand your knowledge. The AI-Chat in mindlib is uniquely tailored to your knowledge base, intelligently searching through your stored insights to provide context-aware answers that are grounded in your own curated information. AI-generated insights can be automatically transformed into structured mind maps, eliminating the need for manual organization and research. Instead of arranging content yourself, simply engage in a natural conversation, and let mindlib handle the structuring. This allows you to effortlessly expand your knowledge while keeping it well-organized and interconnected. To support knowledge organization, mindlib can be a share goal for your weblinks, uses Open Graph to pull information from URLs, and integrates the Google Knowledge Graph to discover relevant entities. A search function, list view, and graphical mind map navigation enable you to quickly access your knowledge and explore new connections. mindlib stores your mind maps locally and synchronizes with a server, ensuring your knowledge is always available—even when offline. The app supports the OPML format for importing and exporting information, allowing easy exchange with other mind mapping applications and creating backups. Use the web application version to access mindlib from your desktop at app.mindlib.de. The free version allows up to 100 pieces of information. Upgrade to a monthly or yearly subscription for unlimited knowledge storage. Once your subscription ends, your existing data remains available and synchronized across all devices.

About

MindStruct

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
