Build an agent that knows your business.
Wire up knowledge, connect your APIs, and design the flows that matter. Symphia gives builders the primitives to ship a capable agent fast — and a dev chat to prove it works before it goes live.

Building blocks
The primitives builders reach for
Everything you need to take an agent from empty to production — grounded, capable, and testable.
Knowledge bases
Upload docs, sync your help center, or point at a URL. Symphia chunks, embeds, and retrieves so answers stay grounded.
RAG that cites
Retrieval pulls the most relevant passages at answer time and keeps a trail back to the source material.
Functions & tools
Define a function, point it at your API, and the agent can call it mid-conversation to take real action.
Journeys
Compose guided flows for specific intents — refunds, onboarding, troubleshooting — with branching and required steps.
Dev chat
Test the agent live as you build. Watch which knowledge it retrieves and which tools it calls, turn by turn.
Embeddable widget
Ship to production with one script tag. Drop it on any page and your agent is live for customers in minutes.
Ground it
Knowledge in, grounded answers out
Add a knowledge base from docs, help-center articles, or a crawl, and Symphia handles chunking, embedding, and retrieval. At answer time the agent pulls the most relevant passages and keeps a citation trail you can inspect.
- Upload files, sync a help center, or crawl a URL
- Automatic chunking and embedding — no pipeline to run
- Retrieval surfaces the passages behind each answer
- Re-sync to keep the agent current as your docs change
Make it act
Turn your APIs into agent actions
Define a function with its inputs and outputs, point it at your endpoint, and the agent decides when to call it. Journeys then orchestrate those tools into guided flows for the intents you care about most.
- Declare functions and connect them to your APIs
- The agent calls tools live, mid-conversation
- Journeys sequence tools into refund and onboarding flows
- Scoped secrets keep credentials out of the agent's reach
Prove it
Test before you ship
The dev chat runs the real agent against your real configuration. Send messages, watch which knowledge it retrieves and which tools it fires, and iterate until it behaves — then drop the widget in production.
- Interact with the live agent as you build it
- Inspect retrieved knowledge and tool calls per turn
- Catch gaps before customers ever see them
- Promote to production with a single script tag
Frequently asked questions
How do I add knowledge?+
Upload documents, sync your help center, or crawl a URL. Symphia handles chunking, embedding, and retrieval automatically, and you can re-sync whenever your content changes.
How does the agent take actions?+
You define functions with typed inputs and outputs and connect them to your APIs. The agent decides when to call them mid-conversation, and journeys orchestrate them into guided flows.
Can I test before going live?+
Yes. The dev chat runs the real agent against your live configuration, showing which knowledge it retrieves and which tools it calls so you can iterate with confidence.
How do I install the agent?+
Add a single script tag to your site. The embeddable widget loads your agent and is live for customers in minutes — no front-end build required.
