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 video script into a newsletter, title options, thumbnail ideas, a social thread and a YouTube description.

Check with me first: Who's the audience, and do I have examples of past posts you should match?

What I'll give you:
- My long-form video script
- Examples of my past newsletters or posts, if I have them

Rules:
- Keep my voice and only use points from the script.
- Make each piece suit its platform.
- If something is missing or unclear, ask me instead of guessing.
- Don't publish anything. Hand everything back for review.

Output: A newsletter draft, several titles, thumbnail ideas, a thread and a YouTube description.

You'll know it worked when: each piece is ready to edit and post without starting from scratch.

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

Goal: Turn my video script into a newsletter, titles, thumbnail ideas, a social thread and a YouTube description.

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

Inputs (fill in or confirm):
- Video script
- Past examples
- Audience
- Platforms for the thread and newsletter

Rules:
- Match my voice from examples.
- Keep claims from the script only.
- Give 5 title options.
- Write each asset to its platform's length.
- Keep the newsletter under [N] words with one call to action.
- Give 3 thumbnail concepts with text under 5 words.
- Include timestamps in the description if the script has sections.
- Mark which ideas come from which part of the script.
- Write the thread so each post makes sense on its own.
- Keep the newsletter subject line under 60 characters and give two options.

If you get stuck: If examples are missing, ask. 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 consistency across assets.

Output: All assets in one doc.

Done when: each asset is ready to post with light edits.
