# Plugins

> The Zero Runtime plugin catalog. Choose a plugin for each pipeline stage: speech-to-text, the LLM, text-to-speech, and more, with usage for Python, JavaScript, and Go.

A plugin handles one stage of the [pipeline](/concepts/pipeline). You import it from
`zrt.plugins` (or the matching path in your SDK) and pass it to the pipeline. Each
plugin page below shows setup and usage in Python, JavaScript, and Go.

Plugins are grouped by stage, because that's how you choose them: pick the best
speech-to-text, LLM, and text-to-speech for your agent.

A "Supported" cell works today but is not documented yet; "-" means that provider doesn't
serve that stage. Availability can vary by SDK, so check each plugin page. Turn detection
(Echo), voice activity detection (Silero), and noise cancellation
([RNNoise](/plugins/denoise/rnnoise), [Sanas](/plugins/denoise/sanas),
[ai-coustics](/plugins/denoise/aicoustics)) are listed below.

Speech-to-speech models that run in the pipeline's `llm` slot (no separate STT/TTS). See
