About

Syntha AI is a desktop application designed for developers that aggregates access to multiple large language models, including GPT-4.1, Claude Sonnet 4.0/4.5, and o4-mini, within a single interface. It provides specialized agents for code generation, explanation, optimization, documentation, visualization via Mermaid, language conversion, automated testing, and PRD creation. The platform uses a credit-based pricing model where different models consume credits at varying rates, allowing users to choose models based on their specific needs and budget.
