# Overview

## Docs

- [Smallest AI Documentation](https://docs.smallest.ai/overview/introduction.md): Start here. Voice Agents for hosted phone and web agents, Models for Lightning TTS, Pulse STT, Hydra speech to speech, and Electron LLM, plus the API reference.
- [API Keys](https://docs.smallest.ai/overview/administration/api-keys.md): Create, manage, and rotate API keys to authenticate programmatic access to the voice agent platform and Smallest AI models.
- [Subscription & Plans](https://docs.smallest.ai/overview/administration/subscription-plans.md): Manage your subscription, compare Pay As You Go vs Enterprise plans, and track credits.
- [Zero Data Retention](https://docs.smallest.ai/overview/administration/zero-data-retention.md): Run Smallest AI without keeping conversation content. Enterprise plans keep no content from voice agent calls, and either never store content on the TTS, STT and LLM APIs or stop retaining it after a window you choose.
- [Organization Members](https://docs.smallest.ai/overview/administration/organization-members.md): Manage your workspace, team members, and their roles.
- [Build voice AI agents with Claude Code, Cursor, or Codex](https://docs.smallest.ai/overview/developer-tools/build-with-a-coding-agent.md): Build voice AI agents with Claude Code, Cursor, or Codex. Paste-ready prompts and MCP for Smallest, plus Lightning TTS and Pulse STT for Pipecat/LiveKit.
- [Context7](https://docs.smallest.ai/overview/developer-tools/context-7.md): Use up-to-date Smallest AI documentation directly inside Cursor, Claude, and other AI coding assistants.
- [Agent Skills](https://docs.smallest.ai/overview/developer-tools/agent-skills.md): Install Smallest AI agent skills to give Claude Code, Cursor, and other AI coding agents expert knowledge of the Smallest AI API — working code on the first try.
