Plugins

Modular software components that extend core functionality without modifying the underlying source code.

Plugins bridge the gap between a base platform and specialized user needs. By utilizing standardized APIs (like the ChatGPT Plugin manifest or WordPress hooks), developers inject custom features directly into existing ecosystems. This architecture powers 43% of the web via WordPress and enables LLMs to access real-time data from tools like Kayak, Wolfram, and Slack. It is the industry standard for scalable, third-party integration.
