About this app

Your mind moves fast. MindStream keeps up.

Most note apps make you do the work - pick a folder, choose a tag, 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 out, something longer or a bunch of thoughts, enter "flow mode," and just talk it out. 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.

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's dark, minimal design stays out of your way. No clutter, no color-coded chaos, no productivity theater. Just a clean canvas that makes your thoughts feel important, because they are.

Free to start. Pro for power thinkers.

The free tier gives you full access to the core capture experience. Upgrade to MindStream Pro at $7.99/month to unlock unlimited Brain Search, unlimited Streams, expanded storage, unlimited daily briefings, unlimited flow mode - everything you need if MindStream becomes your daily driver.

Stop organizing. Start thinking.

What’s new

What's new:
Task cards just got smarter. Add checkboxes to any task and a progress bar appears automatically - tracking your completion percentage as you check things off. Hit 100% and you'll be asked if you want to mark it complete.
Uncheck something on a completed task? It automatically reverts. No manual resets needed.

AI-analyzed cards with subtasks now show the same live progress bar too.
The bar only shows up when there's something to track. Clean and simple.
