- Voice, video, messaging, and AI — one programmable platform, every interface you need.
+
+
+
+
+
+SignalWire is a programmable communications platform for building voice, messaging, video, and AI applications.
+
+## Start here
+
+- [Platform getting started](/docs/platform/getting-started) — Set up a SignalWire Space, get API credentials, and choose an implementation path.
+- [Build your first AI agent](/docs/platform/ai/quickstart) — Create and run a conversational voice agent with the SignalWire Server SDK.
+- [Complete documentation index](/docs/llms.txt) — Browse the machine-readable index of all SignalWire documentation sections.
+
+## Products and capabilities
+
+- [AI](/docs/platform/ai) — Build conversational voice and text agents that can call tools and act on external systems.
+- [Calling](/docs/platform/calling) — Find the primary documentation for programmable calling across PSTN, SIP, and WebRTC.
+- [Messaging](/docs/platform/messaging) — Send and receive SMS and MMS messages and manage production messaging traffic.
+- [Voice](/docs/platform/voice) — Build and control voice calls, call flows, recordings, and related telephony features.
+- [Video](/docs/platform/video) — Add programmable video rooms, conferences, and video communications to applications.
+- [Fax](/docs/platform/fax) — Send, receive, and manage faxes through SignalWire.
+- [Phone numbers](/docs/platform/phone-numbers) — Search, purchase, configure, and manage SignalWire phone numbers.
+- [WhatsApp](/docs/platform/messaging/whatsapp) — Configure and send WhatsApp messages through SignalWire.
+- [Chat](/docs/platform/chat) — Add real-time in-app chat and messaging to client applications.
+
+## Developer interfaces
+
+- [Server SDKs](/docs/server-sdks) — Build agents and control communications from backend applications using supported language SDKs.
+- [REST APIs](/docs/apis) — Provision resources and control SignalWire services through HTTP endpoints.
+- [SWML](/docs/swml) — Describe and execute communication workflows using SignalWire Markup Language in JSON or YAML.
+- [Browser SDK](/docs/browser-sdk/v4/guides/overview) — Add WebRTC voice, video, and chat capabilities to browser applications.
+
+## Tools and migration
+
+- [Call Flow Builder](/docs/call-flow-builder) — Create calling applications with a visual drag-and-drop workflow editor.
+- [WireStarter](/docs/platform/wirestarter) — Scaffold a new SignalWire application from a ready-to-use project template.
+- [SWSH](/docs/platform/swsh) — Use an interactive shell to develop and test SWML scripts and API requests.
+- [Compatibility API](/docs/compatibility-api) — Migrate Twilio-compatible applications to SignalWire with minimal code changes.

+## AI capabilities
+
+Explore the ways you can add AI to text conversations and live calls. Each capability links to its
+canonical API, SDK, or SWML reference.
+
+
+
+
+ Hold text conversations with the same SignalWire AI agent that handles voice calls. Use the REST
+ API directly, [`AIChatClient`](/docs/server-sdks/reference/python/agents/ai-chat-client) from a
+ trusted server, or [`ChatGateway`](/docs/server-sdks/reference/python/agents/chat-gateway) from a
+ browser-facing application.
+
+
+
+ Attach a real-time AI observer that listens to a live call and streams coaching, compliance
+ alerts, or other agent-facing insights without speaking on the call.
+
+
+
+ Translate both sides of a voice conversation in real time, inject translated speech, and request
+ summaries during or after the session.
+
+
+
+ Stream real-time transcripts to your application and request an AI-generated summary while the
+ session is active or when it ends.
+
+
+
+

A conversation moves between the model and your systems as the situation requires:
