What this is

A real workflow someone ran with an AI agent. Copy the prompt into your agent, connect the listed tools, and it runs for you.

  1. Copy the prompt below.
  2. Paste it into your agent (we recommend Grok Bot) and connect the tools listed: whatever the prompt mentions.
  3. Run it once, check the result, then put it on a schedule if it repeats.

What you get

A creator A/B tests 3 titles and then 3 thumbnails, and a ChatGPT-suggested, Nano Banana-rendered thumbnail outperformed both of his originals.

The prompt

Cleaned version rewritten from the source — not a direct quote.

Here are my two thumbnails and video summary. Suggest a completely different angle I haven't thought of, and write a Nano Banana prompt for it (text on image ≤4 words).

Recommended

Try it in Grok Bot

  1. Copy the prompt (button below).
  2. Open Grok Bot chat and paste it. Replace any [bracketed] placeholders.
  3. Connect the listed tools (as needed) as connectors when Grok Bot asks.
  4. If the task repeats, ask: “Make this a daily routine.”

Alternatives: the same prompt works in ChatGPT Agent, Claude, OpenClaw.

Pitfalls & reliability

  • A real A/B test result, though it's one video. Good tip: change one variable at a time.
  • Reddit blocks automated access from our network; this post was not independently re-checked. Figures come from search snippets of the post.

Evidence

A real A/B test result, though it's one video. Good tip: change one variable at a time. Marketing check: PASS: small creator in r/NewTubers. Duplicate check vs agentusecases.ai: no match in sitemap slugs
