Vello

Vello is a multi-model AI chat platform that lets you access many of the top language models — including ChatGPT, Claude, Mistral, Gemini, and Perplexity — all from one app. Instead of juggling tabs or subscriptions across different AI services, you get a single workspace where you can chat, research, and collaborate. It's available as a web app and as desktop apps for Windows and Mac.

What makes Vello stand out is its combination of flexibility and teamwork features. You can hop between models in the same conversation, pick the one best suited for each task, and use the built-in web search model that pulls in real information with source citations. Team spaces let multiple people work together in shared chat rooms and documents, making it practical for group projects. There's also a system for creating custom AI personas — you can train and deploy them to automate specific tasks inside your workspace.

Vello is best for individuals and small teams who want a fast, keyboard-friendly interface without being locked into a single AI provider. Researchers will appreciate the web search with citations, content teams can build drafts collaboratively, and anyone who likes to compare model outputs will find the multi-model setup handy. It's a straightforward tool that puts choice and speed first.
