Build AI agents
your customers
actually use.
The agent platform for businesses that aren't ready to be platforms. Pick a model, paste your knowledge, drop a single-line script tag on your site. Live in five minutes — no provider account required.
Works with the model you already pay for
The platform
One studio, every surface.
Author, share, and embed agents from a single screen. No second admin app. No labyrinth of settings.
Truly model-agnostic
Anthropic, OpenAI, Gemini, OpenRouter, local Ollama. Switching providers is a dropdown, not a migration. Bring your own keys.
Hybrid retrieval, with sources
Vector + lexical retrieval over pgvector. Inline citations open the exact source chunk.
MCP, both ways
Attach any Model Context Protocol server in seconds. Publish your agent as one — every FyrAgent is also a tool other agents can call.
Smart conversation starters
Starter chips are LLM-generated from what's actually in your knowledge base — and re-cluster as the KB grows. Nobody else does this.
Embed in one line
Self-contained web component with Shadow DOM. Bubble + inline modes, themed automatically.
Visible memory
Three-layer memory — global preferences, per-agent overrides, auto-extracted facts. All editable. All on-screen.
Versioned publishes
Drafts edit freely; only publishes affect live conversations. Rollback in one click. Diff any two versions.
Inspectable tool calls
Every tool invocation shows arguments, latency, and result inline in the chat. Debugging finally feels normal.
Scoped keys, share tokens
Org keys, agent-scoped publishable keys, revokable share tokens. Domain allowlists per embed.
The flow
From zero to live in three steps.
Describe the agent
Name it, give it a system prompt, paste a few knowledge sources. We'll auto-generate an avatar, color, and four conversation starters from your description.
Test it next to the config
The live preview replays every change. Switch model providers, adjust the prompt, watch citations and tool calls inline.
Publish and embed
One click to publish a versioned snapshot. Copy a single script tag onto your site, or share the link. Your edits never break running conversations.
One line. Any site. Themed automatically.
Self-contained web component with Shadow DOM isolation. Use the bubble mode for support, the inline mode for landing pages. Pass setUser() to personalize for logged-in visitors.

Visible memory.
Editable preferences.
Versioned publishes.
- Every "remembered fact" the agent infers is visible in the user's panel — and one tap away from deletion.
- Inline citations point at the source chunk, with a snippet on hover.
- Every publish is a versioned snapshot. Rollback in one click, no re-creating.
- Tool calls are inspectable. The agent earns trust by being legible.
