Method:

How we verify

Evidence: Described by posterThe person describes what happened in words, without screenshots or video.

Outcome

Claude Cowork expanded the poster's top 10 podcast takeaways, then used Claude in Chrome to find the transcript and timestamps for each clip, and Codex downloaded them.

The source didn't share its exact prompt, so we wrote this from what it describes.

Here's a task I'd like your help with. Read it all the way through before you start.

Goal: Turn my top takeaways from a podcast episode into fleshed-out notes, each with the timestamp of the matching clip.

Check with me first: Which episode, and how many takeaways do I want to cover?

What I'll give you:
- My list of top takeaways (for example my top 10 highlights)
- The episode name or YouTube link

Rules:
- Fill in the details for each takeaway.
- Find the episode's transcript and the timestamp for each takeaway's clip.
- If something is missing or unclear, ask me instead of guessing.
- Use the transcript for timestamps and don't guess times.
- Stop once the list is done and hand it back to me.

Output: Each takeaway with its details and the start time of its clip, plus the episode link.

You'll know it worked when: I can jump straight to each clip in the episode using the timestamps.

Later I may also ask you to: share the timestamps and video link so the clips can be downloaded with another tool.

Here's a task I'd like your help with. Read it all the way through before you start.

Goal: Turn my top podcast takeaways into fleshed-out notes, each linked to the timestamp of the matching moment.

Quick check first: tell me if anything below is missing or unclear.

Inputs (fill in or confirm):
- My list of takeaways
- Episode link (YouTube or podcast page)
- Note length per takeaway
- Preferred note format (markdown, Notion)

Rules:
- Get the transcript with timestamps from captions or the show's own transcript.
- Find the moment each takeaway comes from; quote the line and give its start time.
- Expand each into a short note using only what's said in the episode.
- Add a clickable timestamped link (e.g. YouTube ?t=).
- Keep each note under [N] words.
- Mark each timestamp as start and end, in hh:mm:ss.

If you get stuck: If you can't find a takeaway in the transcript, say so and suggest the closest moment. If a login, CAPTCHA or two-step code appears, stop and ask me to handle it; never guess or store passwords.

Verify before you finish: Open three of the links and check they start at the right moment.

Output: A markdown doc: takeaway, quote, timestamp link, note.

Done when: each takeaway links to the exact moment it comes from.
