# EVA AI

> EVA is a unified AI workspace that gives users access to every major AI model — ChatGPT, Claude, Gemini, Grok, Perplexity, DeepSeek, Mistral, and Llama — in a single interface. It replaces multiple separate AI subscriptions with one workspace and one credit balance.

## What EVA Does

EVA (Enhanced Virtual Assistant) is a multi-model AI platform that solves AI tool fragmentation. Instead of paying $20/month for ChatGPT Plus, $20/month for Claude Pro, and $20/month for Gemini Advanced separately, users get all models in one place and pay only for what they actually use via a unified credit system.

Key capabilities:
- Access to 8+ AI providers: OpenAI (GPT-4o, GPT-5), Anthropic (Claude Sonnet, Claude Opus), Google (Gemini 2.5 Pro), xAI (Grok 4), Perplexity Sonar, DeepSeek, Mistral, Meta Llama, and more
- Side-by-side model comparison: run the same prompt through up to 4 models simultaneously
- Unified credit system: one balance covers all providers; pay per message, not per month
- Web search: compatible models connect to live web results
- Persistent context: RAG-based memory across chat sessions
- File uploads: documents, images, video, and audio
- Private and secure: EVA does not train on user conversations

## Who It's For

Individual professionals, developers, and indie hackers who already pay for multiple AI subscriptions and want to stop switching between tools. Particularly useful for anyone who needs to compare model outputs (e.g., Claude vs GPT on a coding task) without maintaining separate accounts.
