Building a centralized AI tool aggregator: architecture, API normalization, and latency tradeoffs

I built a small web-based platform that aggregates multiple AI tools into a single interface: https://onlyaitools.lovable.app/ The goal was not to create a product, but to explore the engineering challenges of unifying multiple AI services under one system. Architecture The system is built around a modular architecture where each AI tool is treated as an independent service. A central routing layer handles requests and dispatches them to different external AI APIs depending on the task type. Thi
