How it works
Go from content to live chat widget in minutes
Connect Your Channel
Paste your YouTube channel URL — every video is transcribed and indexed automatically. No manual uploads, no copy-pasting transcripts.
Customize Your Widget
Set the bubble color, logo, greeting message, and conversation behavior to match your brand. Preview changes in real time — no design experience needed.
Embed on Your Site
Copy one script tag and paste it before your closing </body> tag. The chat bubble goes live immediately on any website or CMS.
For people and agents
One knowledge base from your YouTube content, three ways to use it.
For creators
Q&A widget
Index your YouTube channel and embed a branded chat bubble on your site that answers your visitors from your own videos.
For developers
Transcription API
A /v1 REST API with an API key: transcribe YouTube videos, channels and playlists into collections, then ask questions and get cited answers.
For AI agents
MCP server
The same API as MCP tools over Streamable HTTP, so agents like Claude can transcribe, search and query YouTube content directly.
Connect the MCP server
Endpoint https://llmexpert.io/mcp (Streamable HTTP). Authenticate with Authorization: Bearer <API key>.
Create an API key in your dashboard under Settings → Developer API keys, then add this to your MCP client:
{
"mcpServers": {
"llmexpert": {
"type": "http",
"url": "https://llmexpert.io/mcp",
"headers": {
"Authorization": "Bearer YOUR_API_KEY"
}
}
}
}No account? transcribe and query_collection can be paid per call in USDC on Base via x402.
