How it works
One input, any scale, and the output your work needs.
Any video, any audio
Paste a single YouTube URL, a playlist link, or upload an audio file. INDXR handles all three input types from the same interface.
From one video to a whole playlist
Pull one video's captions, queue an entire playlist — up to 500 videos in a single job — or upload hours of audio for AI transcription. The same tool at any scale.
Output: actually readable
Paragraphed plain text, timestamped segments, Markdown with YAML frontmatter for Obsidian or Notion, CSV for data work. Readable, not a raw caption dump.
For: Knowledge workers, researchers, journalists
