Why use this

• You have a single product walkthrough, webinar, or explainer video to add.
• The video isn't on a channel you own — or you only want this one video, not the whole channel.
• The spoken content captures information that isn't written down anywhere.
• You want to give visitors a clickable source link to the video.

How it works

Echo fetches the video's transcript — either the captions YouTube generated or the ones you uploaded — and formats it into time-stamped paragraphs. The transcript is indexed alongside the video title, description, and thumbnail. The AI can then quote specific portions of the video in its answers.

Works with any public YouTube video that has captions or subtitles available.

How it differs from related options

• vs YouTube channel synced source — this is the key choice. Single video indexes one video at a time; the channel synced source auto-imports every public video from a channel and keeps adding new ones as they're published. For 1–5 videos use this; for a whole channel use the synced source.
• vs URL upload — URL would scrape the YouTube page chrome and the description, not the spoken content. This type extracts the actual transcript.

Step-by-step setup

1. Open the assistant and go to Contents.
2. Click Add content and select YouTube.
3. Paste the YouTube video URL (any standard format — youtube.com/watch?v=..., youtu.be/..., or a Shorts link).
4. Click Add.

Transcript extraction takes a few seconds. The video appears in your library with the title, description, thumbnail, and a clickable source link.

Common errors and troubleshooting

• "Transcript not available" — the video has no captions. Either the creator never uploaded any, or auto-captions are disabled. Pick a different video or add the content as text instead.
• "Video is private or unlisted" — Echo can only index public videos. Set the video to public on YouTube or paste the relevant text manually.
• "Region-restricted" — some videos are geo-blocked. Try a different video or use the text upload with a manually transcribed copy.
• Transcript looks garbled — auto-generated captions in noisy environments can be inaccurate. Consider uploading a cleaner transcript as text content.
• The AI uses outdated content from an older version — re-uploading the new video as a fresh entry and disabling the old one is the cleanest fix.
