## What is KUU?

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.

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.


■ 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.


■ 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: cooking, walking, 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.


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.”


— Speak, and free your mind.

### 5/5 — とても気に入りました

*2026-08-28*

Todo リストとして使っています。

優しく受け止めてくれて、

タスクという無味乾燥で義務的なものに落とし込むのではなく、

思索の断片として保存しておいてくれる感じがするのが、とても良いです。

Todoリストと違ってやってもやらなくても良い。

でもやってチェックすると、「手放せた」ことが意識できるので、

心地よさを感じられています。

私の思考の断片を、大切に、大事に、そっと扱ってもらえているような感覚になりました。

UIでこんなに違うものなんですね。

感謝しています。

### 5/5 — いい感じ！

*2026-08-03*

スレッズで見てダウンロードしました。「やらなきゃいけないこと」と「やりたいこと」の優先順位を判断しやすくなりました。頭がパンクする前に、一旦ここに吐き出すようにしてます。

**Developer response:** レビューありがとうございます！Threadsから見つけていただけたのも嬉しいです。「頭がパンパンになる前に、一旦ここに吐き出す」という使い方は、まさにKUUで作りたかった体験そのものです。これからも頭の中に少し余白を作れるようなアプリにしていきます！

### 5/5 — ADHD가 아니더라도

*2026-07-28*

adhd가 아닌 사업으로 바쁜 어머니가 일정을 가끔 잊어버리시고 고생하시는 것을 보고, 딸인 제가 2주정도 먼저 사용 후 추천드리고 설치해드렸습니다.

사용하며 아쉬운 점은
오늘 어머니가 사용하시면서
“오늘”,“내일” 이라고 말하면 그대로 오늘/내일로만 저장이 되는데 (7/31)이러식으로 날짜를 계산해서 놓어주는 것이 있으면 더 편할 것 같다고 말씀하신 부분이었습니다. 

혹시 다음 업데이트에 참고해주신다면 정말 감사할 것 같습니다.

만들어주셔서 감사합니다

**Developer response:** 리뷰 감사합니다.
KUU를 사용해 주시고, 따뜻한 말씀까지 남겨 주셔서 정말 기쁩니다.

말로 꺼낸 생각들을 조금이라도 편하게 정리할 수 있는 앱이 되기를 바라며 만들고 있습니다.
말씀해 주신 날짜 인식 부분도 중요한 개선점으로 보고 있으며, “오늘”, “내일” 같은 표현이 더 자연스럽게 반영될 수 있도록 계속 개선해 나가겠습니다.

사용해 주셔서 감사합니다.

### 5/5 — Simple and effective

*2026-07-27*

This app lets you take voice memos and automatically sorts them as tasks—exactly what I wanted! Really nice, simple design as well. I wish I could also copy/export the task items, and that the app also stored the voice transcripts for longer rambling thoughts.

**Developer response:** Thank you for the review.
I’m really glad to hear that the simple voice-to-sorted-tasks flow is working well for you.

Copy/export options and keeping the original voice transcripts are both very helpful suggestions.
I’ll consider them for future improvements so the app can support longer and more flexible brainstorming sessions.

### 5/5 — 私の代わりに覚えてくれてる

*2026-07-22*

「あ、忘れてたけど今思い出した、でも3秒後には忘れるな」となった瞬間に、KUUに言おう、と繋がっていて、無意識で開き、残すことができるようになった。忘れてもいいや、覚えていたいな、絶対に覚えていたいの！！の順に勝手に分けてくれることで、私の「今」やることリストが少なくて、わかりやすくて最高です。個人的には、「手放す」の欄は必要ないので、非表示にしてその分他を大きく表示できたら嬉しいです〜
とにかく愛用中。

**Developer response:** レビューありがとうございます。
KUUが生活の中に馴染んでいるようでとても嬉しいです。

頭の中に置いておくと重くなるものを、一度外に出しておける場所にしたいと思って作っているので、そのように使っていただけて本当に励みになります。

表示のカスタマイズについてのご意見もありがとうございます。
より自分に合った見え方で使えるよう、今後の改善として検討していきます。

### 5/5 — 使いやすそう

*2026-07-18*

話すだけである程度部類分けしてくれるので活用しやすそうです。

### 5/5 — 最高

*2026-07-09*

物忘れの多い自分に少し自信がついた

**Developer response:** レビューありがとうございます。少しでも自信につながったとのこと、とても嬉しいです。

忘れたくないことや頭の中の考えごとを安心して外に出せる場所になれるよう、これからも改善を続けていきます。

### 5/5 — 「話すだけ」で記録できるタイムライン形式のライフログアプリのご提案

*2026-07-06*

いつもKUUを愛用しています！

KUUとは別コンセプトでも構いませんので、こんなアプリがあったらぜひ使いたいです。

音声で話すだけで、そのまま文字になり、話した時刻が自動で付く、自分専用のXのようなタイムライン形式のライフログアプリです。

例）
7:03　起きた
9:18　洗濯干す
9:34　干し終えた
14:12　めっちゃ眠い
16:46　こんなことがあった。こう思った。

KUUのように話し終えたあとAIが要約・整理するのではなく、話した内容がそのままタイムラインに反映されるイメージです。

必要なときだけAIが、1日の要約や生活リズム・体調の振り返りをしてくれたら嬉しいです。

思考整理やライフログとして活用したい方にも需要があるのではないかと思っています。

このようなアプリが実現したら、ぜひ利用したいです。ご検討いただけましたら幸いです。

**Developer response:** レビューありがとうございます。
いつもKUUを使っていただいているうえに、ここまで具体的なアイデアを書いていただけて本当に嬉しいです。

話すだけで日々の出来事が自動で時系列に残っていく、タイムライン形式のライフログアプリという考え方、とても魅力的だと感じました。
KUUとは別のコンセプトになりそうですが、思考整理だけでなく、生活や記録をもっと自然に残す体験として大きなヒントになりました。

すぐに形にできるかは分かりませんが、今後の開発の参考にさせていただきます。ありがとうございます。

### 3/5 — 声を聞きとる準備をしていますから進めない

*2026-07-02*

キーボードは対応出来るのですが、音声にすると、声を聞きとる準備をしていますから進めないです。
マイクの設定もオンにしているのですが、なにか自分の設定に不備があるのでしょうか。
返答いただけますと幸いです。

**Developer response:** レビューありがとうございます。
音声入力時に「声を聞く準備をしています」から進まないとのこと、ご不便をおかけして申し訳ありません。

最新バージョン 2.0.0 で、音声入力まわりの処理を見直しました。同様の症状についても改善している可能性がありますので、アップデート後に再度お試しいただけますと幸いです。

引き続き、安心して使えるよう改善を続けていきます。

### 4/5 — 書き起こし

*2026-06-30*

ぶつぶつ取り止めもなくても認識、列挙と整えてくれるのでありがたい。さらにそこからカテゴリー分けとなるとヘビーユーズしてしまいそう

**Developer response:** レビューありがとうございます。
書き起こしから整理までの流れを便利に感じていただけて嬉しいです。

カテゴリ分けについても、より使いやすくなるよう改善を進めています。
今後も、話した内容をより自然に整理できるアプリになるよう改善を続けていきます。

### 2.8.0 — 2026-08-28

Here's KUU 2.8.0.

What's new in 2.8.0

■ Write straight into a place from the widget
Each place on the widget now has a “+”. Touch it and “Write it down” opens; what you write goes straight into that place. When editing the widget you can switch to a single button, or none.

■ A way out for words that couldn't be sorted
When things get busy and sorting fails, KUU quietly tries once more. You can also leave the words as they are — and see where they landed right away.

As always, we're here to help a little space return to your mind.

### 2.7.0 — 2026-08-17

Here's KUU 2.7.0.

【What's new in 2.7.0】

■ Fix an item right where it sits
If something was misheard, touch the item and fix it right there. Keep or don't keep has moved to press and hold — right-click on the Mac. Picking an item up and carrying it somewhere else works just as before.

■ A closer time for "Remind me later"
"In 30 minutes" and "In 1 hour" have joined the choices. A time you pick late at night arrives just as you set it, instead of waiting for the morning.

■ The same things, now on the Mac
"Remind me later", your own morning and evening times, five new languages and a handful of small fixes have arrived on the Mac as well.

As always, we're here to help a little space return to your mind.

### 2.6.0 — 2026-08-15

Here's KUU 2.6.0.

【What's new in 2.6.0】

■ "Remind me later" is here
Press and hold an item on the tidying screen to choose "Remind me later". Tonight, tomorrow morning, next week — or a date and time — and KUU quietly reminds you then.

■ You decide what time it arrives
Set your own morning and evening times. "Tonight" arrives at your evening time, "Tomorrow morning" and the rest at your morning time.

As always, we're here to help a little space return to your mind.

### 2.5.0 — 2026-08-10

Here's KUU 2.5.0.

【What's new in 2.5.0】

■ "Sort again" is now "Edit what you said"
In the list that follows what you said, "Sort again" is now called "Edit what you said". The name finally tells you what it's for.

■ The tidying screen no longer feels sluggish
The tidying screen could feel sluggish at times — that's fixed. And the note that brings back what you let go no longer disappears right away.

■ Now in Arabic and Hebrew
KUU is now available in Arabic and Hebrew. The screen follows the writing direction, laid out from right to left.

As always, we're here to help a little space return to your mind.

### 2.4.0 — 2026-08-07

Here's KUU 2.4.0.

【What's new in 2.4.0】

■ Editing no longer stumbles
When you tweak what you said, moving to another line no longer closes what you were writing. You can now place your cursor right at the start of a line, too.

■ The first-time guide stays till the end
Tips on how to use KUU no longer vanish before you've finished reading them.

■ KUU+'s theme sorting, ready right away
Once you join KUU+, you can switch it on right there on the welcome screen. No need to dig into settings — what you say sorts itself by theme.

As always, we're here to help a little space return to your mind.
