Research across several AI models usually means juggling separate accounts, tabs and subscriptions. llmchat.co puts that under one roof.

It is an AI research tool and chatbot platform built for deep research and agentic workflows, with a stated focus on privacy and open-source principles.

You get three search modes: Web Search for quick lookups, Pro Search for more involved questions, and Deep Research for longer investigations. llmchat.co works with a range of model providers, and you can bring your own API keys, so you choose which models handle your queries instead of being tied to one vendor.

That bring-your-own-key setup suits people who already pay for API access and want a single interface over it.

The open-source and privacy angle will matter most if you are cautious about where your research questions end up.

Pricing is not something to assume, so check the site before committing to a workflow.
