Arcmira: YouTube Transcript Search

Arcmira searches indexed YouTube and podcast transcripts for quotes, mentions, sponsors and recommendations. Use the web app, API or MCP to find passages with timestamps and source links for research and clip discovery. Premium audio-derived, speaker-labelled transcripts are available separately from existing captions. Paid reads use credits from your plan, then your on-demand budget. Check important quotes and AI-derived sponsor classifications against the recording. API docs: https://arcmira.com/docs
