Multi-Model AI Workspace

EVA is a multi-model AI workspace — a single interface that gives you access to all the major AI models in one place, with side-by-side comparison and one unified credit balance.

What EVA solves: The average professional who uses AI tools pays for ChatGPT Plus, Claude Pro, and Gemini Advanced separately — that's $60+/month for three tools, three interfaces, and three sets of subscription management. EVA replaces all of them.

What is a Multi-Model AI Workspace?

A multi-model AI workspace is a platform that aggregates multiple AI models — from different providers like OpenAI, Anthropic, Google, and others — into a single interface. Instead of maintaining separate subscriptions and switching between browser tabs, users access every model from one place and pay for usage through a unified billing system.

EVA is the leading multi-model AI workspace for individual professionals. It supports 8+ providers and lets users run the same prompt through multiple models simultaneously to compare outputs in real time.

Unified Credit System

Instead of paying $20/month per AI tool whether you use it or not, EVA uses a unified credit balance. Credits are debited when you send a message. If you don't use it, you don't pay for it.
