## What is Pyunto?

A place to write how you feel right now, with peace of mind.

Pyunto is a private diary app for one person, two people, or a group. No account or email needed: open it and write. Every entry is encrypted, and the AI assistant runs only on your device. You can even invite an AI agent or a robot into a diary as a member.

WHY PYUNTO

Solo diary, exchange diary for two, group diary - one "space" per relationship
On-device AI: your diary is not sent away to power the assistant
Everything encrypted in transit and in storage
iPhone, Mac, other phones and PCs; 17 languages

WRITE AND KEEP

Text, photos and videos, up to 10 per post
Edit after posting: text, photo, date and time
Album: all photos and videos of a space in one grid
Hashtags (outfit, food, concert), offline search
Quick lists: log medicine, meals or books read in one tap, with counts by week, month and year
Mascot stickers, reactions

HOW PEOPLE USE IT

Outfit diary: photograph what you wore. Calendar and album show what you wore on which date and with whom, so you never repeat an outfit when you meet the same person again. Tag entries as date, girls night or office and ask the assistant for outfit tips for today's weather
After-school exchange diary: a secret notebook for best friends, with stickers, reactions and 100 background themes
Fandom, concerts, cafes, travel: relive it all in the album
Study, fitness and skincare logs
Five minutes before bed: one line a day, a weekly reflection on Sunday
Couples: exchange diary with daily missions and anniversaries
Parenting: share feeding and story time
Aging parents: medicine logged in one tap, family reacts
Work: team logs, field photos, care notes

AI ASSISTANT

Runs on your device. The model is a one-time download of several GB (Wi-Fi recommended)
Tap the assistant button on an entry for a reply that fits it - it understands photos too
One-on-one chat when you want to talk
Weekly reflection: your week summarized, with mood per day
Missions (daily writing prompts), up to 20 speaking styles, automatic thread titles
Tools: weather and outfit advice, news, recipes, nearby places, translation
Pyunto Time Management link: "What's on today?", "Book a meeting tomorrow morning"

INVITE AN AI AGENT OR A ROBOT 

Diary members need not be people. Invite an AI agent or a robot you run yourself by QR code.

AI agent: a language tutor, strength coach, nutrition adviser or study partner. You define its role and character; it replies in the diary and can read meal photos
Robot: write "go and find some sunlight" in plain words. It moves, then reports with photos from its own camera and measurements. No commands to learn. Robots act only on instructions from people
You approve every invitation on your phone Note: running an agent or robot requires a computer you control.

### 5/5 — かわいい！♡

*2026-09-16*

10年ほど瞬間日記を利用しており、アプリの中からこちらのアプリを見つけてダウンロードしてみました。めちゃくちゃ可愛い〜！
 文字のサイズ変更ができるようになると嬉しいです！

**Developer response:** フィードバックをいただきまして、ありがとうございます。
また、瞬間日記も長期に渡って、ご愛顧いただきまして、本当に嬉しく思います。

フォントサイズについては、本日リリースしました version 3.4 以降に対応しています。
設定画面からお試しいただけますでしょうか。もし、ご不都合な点などがあれば、また、こちらや、アプリ内の設定画面にあります「開発者への不満」の欄から、ご送付いただけましたら、直接開発メンバーにも伝わりますので、改善に努めます。

今後とも、Pyunto, 瞬間日記ともに、どうぞ、よろしくお願い申し上げます。

### 1/5 — Twitterの代わりなら

*2026-08-14*

サブスクが高いですが一人で使うなら無料で問題ないです
AIを入れるとものすごく容量を食います
AIなしで淡々とひとりごとを打つのに使うならいいかもしれません

**Developer response:** レビューをいただきまして、ありがとうございます。
いただきましたご意見を開発チームで共有し、モデルの容量については、改善できるように調査・研究を進めて参ります。
どうぞ、よろしくお願い致します。

### 4/5 — オフラインでは使えない！

*2026-08-04*

全てはサーバーとの通信で成り立つ！
データはサーバー！

サーバーが飛んだら全てのデータが

なくなる！

**Developer response:** レビューいただきまして、ありがとうございます。

このアプリは、最初にローカルにデータを保存したあと、可能な場合にデータを暗号化した上でサーバにもバックアップを保存しています。（保存したユーザおよび、交換日記やグループ日記の相手のみしか閲覧できない暗号化を採用しています）

これにより、サーバに万が一障害などが発生しました場合は、ローカルのデータのみでお使いになれるように、設計はしておりますが、わかりにくい点は、申し訳ありません。今後改善してまいります。

また、この機能により、後からアカウントを作成されたユーザの皆様が、スマホやパソコンなど複数の端末でご利用いただくことが可能になります。

ローカルデータのみでお使いになります場合は、「瞬間日記」など他のアプリもご検討いただけましたら幸いです。（その場合、WiFi経由でバックアップを取れるようにするなどの手段を提供しています）

以上、どうぞ、よろしくお願いいたします

### 5/5 — 子供と交換日記

*2026-07-09*

登録が簡単ですぐ始められました。

LINEをやりたがっている小学生の子供と、その代わりにこのアプリで交換日記をしています。クローズドで安心だし、親子のやりとりが日記として残っていくのが思った以上に楽しいです。画像も送れるので、その日の写真を貼って見せ合ったりしています。

ちょっとした書き留めに、ひとり用の簡単なメモとしても使えて便利です。AI機能もこれから充実していきそうなので期待しています。

**Developer response:** レビューいただきまして、ありがとうございます
ご期待に添えるように、今後も、改善していきます。
小学生のお子様との、大切な日々をより豊かにすることに、Pyuntoが少しでも役立てましたら幸いです。
引き続き、どうぞ、よろしくお願い致します。
