⚖️ Pros & Cons Analysis

• ✅ The Good: Exceptional accuracy benchmarks and a commitment to citing reputable sources for every claim.
• ✅ The Good: Versatile multi-model support, giving users access to the best strengths of OpenAI, Google, and Anthropic in one place.
• ❌ The Bad: Many of the most powerful features, including Deep Research and specific advanced models, are locked behind the Pro subscription.
