When your head is full, it can be hard to know what belongs in front of you and what can wait. KUU is a quiet voice-first app for brain dumps, overthinking, scattered ideas, and the small worries you do not want to keep carrying. You can speak what is on your mind. It does not need to be organized. KUU turns what you said into text and gently separates it four ways: Now / Later / Park / Let go. The point is not to do more. It is to make a little room in your head. ■ When to use it - Before bed, when your mind starts running. - When the same thought keeps looping. - When task managers have started to feel heavy. - When you want to be heard, but do not want to send it to anyone. - When talking out loud helps you understand what you mean. - When an idea appears before it has a shape. - When you do not want to forget something, but it is not ready to act on. - When voice feels easier than typing. - When your hands are busy: driving, cooking, getting ready, or moving through the day. ■ The 4 ways Now — Something that may feel lighter if you look at it soon. Later — Something to return to at another time. Park — An idea, feeling, or question that does not need an answer yet. Let go — A worry or thought you may not need to keep holding. These are not priorities or scores. They are quiet ways to hold what you said. ■ How KUU is different - Unlike a notes app, KUU starts with speaking, not writing. - Unlike a task manager, KUU does not turn every thought into something to do. - Unlike an AI chat, KUU does not give long advice or add more things to think about. KUU receives what you said and separates it into smaller, easier pieces. ■ What you can do - Speak naturally, even when your thoughts are all mixed up. - See your words as text. - See only what needs your attention now. - Keep later thoughts, parked ideas, and things to let go in their own places. - Revisit what you have said when you want to. ■ Voice and data - Raw audio is not kept. - What you said is saved as text so you can look back later. - Sorting uses AI. Only your words as text are sent, and nothing is kept. - Your saved text syncs only to your private iCloud. - Other people, and the app developer, cannot read it. ■ On your Mac KUU waits quietly in the menu bar. You can speak without opening a window, and it carries all the way through to Now / Later / Park / Let go. What you said before is always a glance away. KUU is not here to add more thoughts. It is here for the space between: “I do not need to solve this right away” and “I do not want to keep holding it in my head.” — Speaking makes room in your mind.
