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.
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.
EVA gives you access to every major AI model without managing separate accounts:
| Provider | Models Available | Best For |
|---|---|---|
| OpenAI | GPT-5, GPT-4o, GPT-4o mini | Reasoning, coding, general tasks |
| Anthropic | Claude Opus 4, Claude Sonnet, Claude Haiku | Writing, long-form analysis, coding |
| Gemini 2.5 Pro, Gemini Flash | Research, spreadsheet logic, multimodal | |
| xAI | Grok 4, Grok 3 | Up-to-date answers, web context |
| Perplexity | Sonar Pro, Sonar | Web search, live information |
| DeepSeek | DeepSeek R2, DeepSeek Chat | Cost-efficient reasoning |
| Mistral | Mistral Large, Mistral 7B | Fast, efficient tasks |
| Meta | Llama 3.3, Llama 3.1 | Open-source baseline, experimentation |
EVA's Compare Mode lets you send the same prompt to up to 4 AI models simultaneously and see their responses side by side. This is useful for:
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.
| Plan | Monthly Price | Credits | Models |
|---|---|---|---|
| Free | $0 | 1,000/month + 100 daily | Basic models |
| Basic | $9.90 | 10,000/month | Standard models |
| Plus | $19.90 | 25,000/month | Plus models + reasoning |
| Pro | $49.90 | 75,000/month | All models |
The problem with maintaining separate AI subscriptions:
EVA provides access to models from OpenAI (GPT-5, GPT-4o), Anthropic (Claude Opus 4, Claude Sonnet), Google (Gemini 2.5 Pro), xAI (Grok 4), Perplexity (Sonar Pro), DeepSeek, Mistral, and Meta Llama. New models are added as providers release them.
