How we verify

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

PartialThe source says it only partly worked, or had a significant problem a person had to deal with.

What went wrong: Good on English videos; slow and missed key points on a Tamil one.

Outcome

Comet Assistant summarized English YouTube conversations quickly and well, but on a Tamil discussion it had to play the whole video and made a few mistakes, missing some crucial points.

Prompt Improved prompt

Strengthened by us to avoid the problem in the source. Not tested by the poster. It doesn't change what happened in the source.

Let's work this out together. I'll tell you what I'm after; help me sharpen the goal before you dive in, and check in with me before anything you can't undo.

Goal: Help me get the key points from videos, including ones in other languages.

Questions to explore first: Which videos and languages, and what will I use the summary for?

What I'll give you:
- Video links ([URLS])
- What I care about (e.g. main arguments, decisions)
- The language of each video

Rules:
- Start by restating my goal and suggesting 2–3 ways to approach it; recommend one.
- Tell me if a video has no transcript; for non-English videos, note that accuracy may be lower.
- Give timestamps for each key point so I can check.
- Flag anything you were unsure about rather than guessing.
- Say whether you used a transcript or had to play the video.

Output: A summary per video with timestamped points and a confidence note, plus 2–3 suggested next steps.

You'll know it worked when: I can jump to each timestamp and it matches the point.

Try this in:

This prompt has blanks to fill in, like [URLS]. We'll copy it instead of filling it in, so you can edit it before you send.

The prompt they actually used (our rebuild)

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

Optional stronger version

Our rewrite with extra checks. The poster didn't test it.

Let's work this out together. I'll tell you what I'm after; help me sharpen the goal before you dive in, and check in with me before anything you can't undo.

Goal: Get the key points from videos, including ones in other languages, accurately.

First: restate the goal in one sentence, suggest 2–3 ways to approach it, recommend one, and wait for my pick.

Inputs (fill in or confirm):
- Video links
- What I care about
- Language of each video

Rules:
- Get captions or transcripts in the original language first.
- For non-English videos, translate the transcript section by section, then summarize.
- Quote key lines in the original language with translation.
- Mark confidence per video.
- Note the language of each video and give summaries in English unless I ask otherwise.

What went wrong before, and how to avoid it:
- Last time it was slow and missed key points on a Tamil video: work from the full transcript and translate before summarizing.

If you get stuck: If no captions exist, say so rather than summarizing from the title. 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: Check that each summary covers the whole video, not just the start.

Output: Per video: key points, quotes with timestamps, confidence, plus next steps.

Done when: summaries are complete for every language.
