What is You.com?

You.com is an AI search and chat assistant built by a team that includes former Salesforce chief scientist Richard Socher. Rather than returning a list of links it answers in prose with citations, and it lets you choose which underlying model handles the request, so a quick factual lookup and a long research task can run on different engines. Custom assistants save a persona, uploaded files and preferred sources, and an API exposes the same search and model access to developers. The free tier covers everyday searching; heavier research modes and assistant features sit on the paid plan.

FAQ

How is You.com different from a chat assistant?

It pairs a web index with language models. Answers arrive with citations you can open, and the product is organised around searching and reading the live web rather than holding a long conversation, though chat is available too.

Can I choose which model answers?

Yes. Several hosted models are offered alongside the company's own, and you can switch between them. In practice that means a fast model for simple lookups and a stronger one when a question needs real reasoning.

Is there an API for developers?

Yes. The platform exposes search and model endpoints, which is how teams add grounded answers to their own products instead of sending users out to another website.
