Your mind moves fast. MindStream keeps up. Most note apps make you do the work, pick a folder, choose a tag, and figure out where something goes. MindStream flips that. You capture the thought, and it takes care of the rest. Speak It or Type It Have a quick thought? Just type it. Something longer, or a whole torrent of ideas? Enter Flow Mode and just talk. MindStream instantly understands what you've captured, whether it's a task you need to do, an event to remember, an idea worth keeping, or a note to revisit, and organizes it automatically. No extra steps required. Capture Without Friction Voice or text, morning or midnight, getting a thought into MindStream takes seconds. No menus, no categories to choose, no friction between your brain and the blank space. Just capture and move on. Smart Organization, Automatically The moment you save a thought, MindStream intelligently classifies it. Tasks, events, ideas, and notes each get their own treatment, deadlines are recognized, dates are extracted, and everything lands exactly where it belongs. Your brain dumps; MindStream tidies. Brain Search: Find Anything Instantly Forget scrolling through endless notes trying to remember where you put something. Brain Search lets you ask naturally - "what was that idea about the website?" or "tasks due this week", and surfaces exactly what you're looking for. It's like having a conversation with your own memory. Streams: Think in Context Not everything belongs in the same pile. MindStream's Streams separate your Work life from your Personal life from your Creative side, so the right thoughts are visible when you need them. Switch contexts in a tap. Project View: Your Stream, Structured When a project needs more than a timeline, flip any Stream into a Project Board. Organize your cards into stages - To Do, In Progress, Done, or whatever stages fit how you think, and watch scattered thoughts transform into a trackable workflow. Toggle back to your standard stream view anytime. All your thoughts stay in one place; Project View is just a clearer lens on them. Morning Briefing: Start Every Day Clear Each morning, MindStream gives you a personalized summary of what's ahead, your tasks, upcoming events, pinned reminders, and anything that needs your attention. No digging required. Just clarity. Tidy Up: Polish Your Thoughts Raw ideas often come out messy. Hit "Tidy Up" and MindStream transforms scattered thoughts into clean, structured notes with proper formatting, bullet points, and headers, ready to share or act on. Designed to Feel Like Yours MindStream comes in a focused dark mode and a clean, warm light mode, whichever lets you think best. No clutter, no color-coded chaos, no productivity theater. Just a canvas that stays out of your way and makes your thoughts feel important, because they are. Free to start. Pro for power thinkers. The free tier includes 5 AI actions per day with full access to core capture and two streams. Upgrade to MindStream Pro at $7.99/month to unlock unlimited Brain Search, unlimited Streams, unlimited Flow Mode, unlimited Morning Briefings, Project View boards, Tidy Up, expanded storage, and everything you need when MindStream becomes your daily driver.
