Overview
What is Arcmira: YouTube Transcript Search?
The search engine for the spoken web.
Arcmira lets researchers, developers and AI agents search indexed YouTube videos and livestreams for what people said, with timestamps to check the source.
Find speaker appearances, people, organizations, products and topics mentioned across videos. Research recommendations and likely sponsored ad reads in context. AI classifications are signals to investigate, not definitive proof of sponsorship.
Use the web app, API or MCP to bring spoken-media research into your workflow. Premium transcripts provide speaker-attributed transcription beyond ordinary captions. Search covers Arcmira's indexed collection, not every YouTube video.
Free and paid plans are available. Paid reads use credits from your plan, then your on-demand budget.
