Arcmira: YouTube Transcript Search

Arcmira helps researchers, marketers and developers find who said what across indexed YouTube videos and livestreams, with timestamped source links. Search spoken passages, track mentions of people, organizations, products and topics, and research recommendations, channel sponsors and ad reads. Use the web app, REST API, Python and TypeScript SDKs, CLI or MCP. API documentation: https://arcmira.com/docs. Product: https://arcmira.com. OpenAPI schema: https://api.arcmira.com/v1/openapi.json. MCP and skills: https://github.com/arcmira/mcp. Coverage is limited to indexed content. Speaker attribution and sponsorship classifications can be imperfect; check the cited recording. Premium transcripts and creator captions are distinct sources. Availability and access depend on your plan. Paid reads use credits from your plan, then your on-demand budget.
