đ Works best with your billing tool. Connect Stripe or Whop and Jeremy AI pulls your real offer name and price into the brief. It only reads.
A 15-second vertical ad with voiceover, built from a single paragraph.
You'll see the brief pasted in, the 15-second ad, the voiceover and cards, and the hook-only variant.
What this use case does and who it's for
You paste a short brief. Jeremy AI makes a finished 9:16 video with a voiceover and big on-screen text. It also prints the voiceover script and the 3 text cards as copy. Then you ask for a second version where only the first 3 seconds change, so you can run a clean A/B test.
It's for info-business owners and agencies who need a steady flow of short video ads for Meta and have no editor on call. Creative volume is where most people get stuck. This gets you unstuck.
The A/B step follows a simple rule: change one thing at a time. Here, that thing is the hook.
What you need before you start
A Jeremy AI account. Nothing to connect to try the sample.
A short brief: what the offer is, who it's for, the price, the main promise and the tone.
Only facts you can back up. The sample has no proof or testimonials, so none are used.
Speakers or headphones. Your finished ad has a voiceover.
How to set it up
You use the default Jeremy AI worker. There's nothing to build.
Open Jeremy AI and go to Chats.
Click Create a new chat.
Paste prompt 1. Swap in your own brief.
Click Send message.
Wait about 3 to 4 minutes. A video card appears.
Play the video in the viewer with sound on. Read the voiceover and the 3 text cards printed below it.
Only if the first reply is a script with no video, paste the fallback line.
Paste prompt 2 for the hook-only variant. Wait for the second video.
Play both and compare. Upload the winner to Meta yourself.
The prompts
Prompt 1 is the revised prompt from the walkthrough. The business, the price and the promise are SAMPLE and made up. It tells Jeremy AI not to draw text inside the clips. That's because AI-drawn text tends to come out garbled. The text gets added afterward as crisp overlays.
Make me a 15-second vertical (9:16) video ad for Meta Reels. GENERATE THE VIDEO NOW. Do not just write a script.
Brief (SAMPLE, made-up business):
SAMPLE Launchpad Lab: a 6-week group program that helps first-time course creators get their first 20 paying students. Audience: people with a skill and a small audience who are scared to launch. Price: $497. Promise: "Your first 20 students in 6 weeks, or we keep coaching you free until you get them." Tone: calm, confident, slightly funny.
Rules:
- NO on-camera person and no real person's likeness. Use a warm voiceover plus big on-screen text over clean, modern b-roll (laptop, notebook, a calendar filling up, a notification count ticking up).
- Structure: 0-3s hook that stops the scroll, 3-10s the problem and the promise, 10-15s offer and call to action ("Link below").
- Use only the facts in the brief. No invented numbers, results, testimonials or logos. Put a small "SAMPLE" label in a corner.
- Keep on-screen text under 8 words per card.
- Do NOT ask the video model to draw any text, numbers or UI words inside the clips (AI-drawn text comes out garbled). Generate text-free b-roll with no people at all, not even from behind or as hands, then add every on-screen text card and the SAMPLE label afterwards as crisp overlaid text in post (ffmpeg), so all text is sharp and spelled correctly.
After the video, give me the exact voiceover text and the 3 on-screen text cards.
Use this only if the first reply is a script and no video.
Yes, generate the video now. Same brief, same rules: 9:16, 15 seconds, voiceover plus on-screen text, no on-camera person.
Prompt 2 builds the A/B variant.
Now make a second version for an A/B test: same video, but change ONLY the first 3 seconds with a different hook. Tell me the old hook, the new hook, and what the test is for.
Prompting tips and how to adapt it
Keep "GENERATE THE VIDEO NOW." Without it, the first reply is often just a script.
Keep the no-people rule. In testing, the presenter changed between the two clips. B-roll with no people avoids that.
Keep the text rule. Text-free clips plus overlaid text means sharp, correctly spelled words.
Write the structure in seconds. Hook, problem and promise, then offer and call to action. Change the timings if you like.
Cap the words. Under 8 words per card reads well on a phone.
Use only facts from the brief. If you have real proof, add it to the brief. If you don't, say so.
Test one thing. For prompt 2, you can also ask for a different call to action or a different offer line instead of the hook. Change only one.
The result to expect
A 15 to 16 second, 720x1280 vertical video with a voiceover and text cards. Below it, the exact voiceover text and the 3 on-screen text cards.
Then a second clip. It matches the first except for the opening hook. Jeremy AI tells you the old hook, the new hook and what the test is for.
The video shows the whole run in about 1 minute 40 seconds, with the long waits sped up. Heads up: the walkthrough video is silent, so you won't hear the voiceover in it. Play your own ad with sound on, because the voiceover can sound a bit robotic.
The brand and details are sample data.
Common mistakes and fixes
You got a script and no video. Send the fallback line. It tells Jeremy AI to make the video now.
Text in the clip is garbled. Keep the "don't draw text in the clips" rule. The overlays should be clean.
A person shows up on camera. Keep the "NO on-camera person" rule in the prompt.
The voiceover sounds robotic. Listen before you post. Ask for a warmer, slower read, or change the tone words in your brief.
The video looks off. Quality varies by run. Send it again until the clip is clean. Don't publish one you wouldn't be proud of.
You expected it to upload to Meta. It doesn't. You upload it yourself.
