Kael, In A Conversation.
The same Kael behind the API and behind Harness — here, just talk to it.
Ask Anything.
Sending opens Quan Chat in the app.
Built For Accuracy, Not Speed.
Most chat products are tuned to answer fast. Chat is Kael, the same Kael behind the API and Harness, and Kael is built to be right: it thinks before it answers, and it takes longer than most assistants because of it.
Requests and answers can also be screened, so a harmful request or response can be stopped before it is delivered, not after.
It Thinks Before It Answers.
Chat is built for getting the answer right, not for getting it first. That means it can take longer to reply than the quickest assistants you have used. The deep-reasoning toggle in the composer above lets you ask for more thinking on a hard question, and the web toggle lets it look things up.
Because Chat runs on Kael, it is strongest at the same things Kael is: coding, security, software engineering, agentic work and math. It can write stories and other creative text, but that is not what it is tuned for, and Kael is currently built for English.
