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 YohjiWhat it can do
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
As you chat, Yohji quietly saves lasting facts about you (up to 80) — or you can say “remember that …”. Ask “what do you remember about me” to see it all, and say “forget …” or “forget everything” to remove things. Passwords, codes, card, bank and ID numbers are filtered out and never saved. Your memory belongs to your account only, is encrypted on the server, and is deleted when you delete your account.
