Yohji

An AI assistant that talks with you, looks things up, browses websites while you watch, makes pictures, and remembers what matters, all in one app.

Open Yohji

What it can do

Chat & voiceType or tap the mic and talk. Yohji answers out loud too.

Web search with sourcesQuestions about the real world (news, prices, shows, people) are searched live and come back with sources.

Browses for you“Browse for oil drum suppliers”: Yohji opens its own browser on the server and you watch it live. It never logs in or types passwords, and asks Allow / Deny before pressing anything important.

Shop for me“Find me a 200L oil drum under $100”: Yohji checks Shopee, Lazada and Amazon and shows the best 3. Tap Buy to open it in your own shop app. Yohji never signs in to your shopping accounts.

PicturesMake and edit pictures in the chat (“make it darker”, “at night”), or use a photo of yourself.

Photos & filesAsk about a photo, PDF, Excel, Word or PowerPoint file, e.g. “what's the total?”.

Thinks harder when you askSay “think hard” or “in detail” for a deeper, step-by-step answer from Yohji's strongest brain.

Remembers youKeeps a short note of lasting facts (your name, role, projects, preferences) so you don't repeat yourself.

My space & HubNotes, to-dos, links, smart-home buttons, money and habit tracking, countdowns, music controls and daily games.

Connected appsOptionally connect Google (Gmail and Calendar, read-only), Spotify and Discord shortcuts.

Yohji MiniOn a PC (Chrome or Edge), a small Yohji floats over your other apps. Drop a file on it and ask.

For maintenance teams

Yohji started as a tool for the Mechanical team at Changi Airport Terminal 4. Work (department) accounts, approved by the Yohji administrator, add building sensor readings, job tickets, fault reports and shared files for that team. Personal accounts never see any work data.

The AI behind it

Yohji's answers come from Claude, made by Anthropic. Some accounts can also switch to OpenAI's GPT models. Yohji adds the parts a plain chatbot doesn't have: memory, live web search, its own browser, pictures, voice, connected apps and the team tools. It reaches these models through their business APIs, whose terms don't use your messages to train their models by default.

How memory works

Every few messages, Yohji quietly updates a short note about you, at most 12 lines of lasting facts. It's told never to store passwords, keys, card numbers or ID numbers. The note belongs to your account only and is deleted when you delete your account.
