How to ask questions about supported online video
Turn supported videos and podcasts into searchable material — with answers that cite the source timestamp when available.
From watching to asking
On supported YouTube videos, lectures, webinars, and podcasts, Silestis creates a transcript you can question. Ask for key takeaways or decisions and get clickable [mm:ss] references when the selected mode provides timestamps. Link compatibility depends on the source, permissions, and stream format.
Answers you can trust and verify
When the selected mode provides timestamps, answers can include source references so you can jump back and verify them. The transcript is the substrate; the product is the answers, summaries, and search on top.
See it for YouTube videos, podcasts, and lectures.

Do the answers cite where they come from?
With a timestamp-capable mode, answers can include clickable [mm:ss] references so you can verify them against the source.
Start from the supported lecture page you already use.
Open the video and click Silestis to start a transcript, summary, and notes workflow on the page. Timestamp-capable modes can also return cited answers, including when no source transcript exists.
