App Promo Video: Show Your App, Drive Installs
Make an app promo video that shows real screens and key flows. Describe your app and Pexo builds a polished promo with voiceover, captions, and a clear install CTA, sized for the stores and social.
Describe your offer and this AI video sales letter maker writes the hook, pick a voice and format, then generate a polished VSL that names the problem, raises the stakes, and closes on your call to action in minutes.
Start from a single line of text, a product photo, or the sales copy you already wrote. The video sales letter maker writes the script, generates every shot across Seedance 2.5, Kling AI 3.0, MiniMax H3 and Happy Horse 1.0, and stitches them into one continuous, edited cut. Mix text to video, image to video, and script to video inside the same project. No timelines, no keyframes, no editor to open.
Pexo writes every AI video sales letter along the structure that actually moves people to buy: a hook that earns attention, a problem the viewer recognizes, agitation that raises the stakes, then the solution, the offer, and the close. It orders the argument the way seasoned direct-response writers do, so each beat sets up the next instead of wandering. You describe the offer and Pexo handles the persuasion logic, not just the visuals. The result is a letter built to sell, not a montage with narration.
Pexo layers natural AI narration over the whole letter so the argument is spoken in a confident, human voice that keeps viewers listening. Clone your own voice or dub the same script into another language, then burn in clean captions so the exact pitch reads word for word with the sound off, which is how most cold traffic watches. Your video sales letter lands whether someone is wearing headphones or scrolling in silence.
Every Pexo video sales letter builds toward a single action and ends there, with a closing frame that states the offer and the exact next step. The whole arc is scripted so the momentum you built through the problem and the agitation cashes out at the CTA instead of fading. Choose the action, a purchase, a booking, a signup, and Hyperframe holds your product, colors, and framing steady from the hook to the close. Viewers reach the end knowing precisely what to do.
The video sales letter generator delivers natively in 16:9 for YouTube, 9:16 for TikTok and Reels, and 1:1 for feeds, up to 4K and anywhere from 5 to 120 seconds. Each aspect ratio is generated fresh for that screen, with the composition framed for it rather than cropped down from one master. Ask for several formats at once and post the right cut to every channel and every funnel step. It looks intentional everywhere it lands.
I pasted my sales page in and the video sales letter maker returned a 90 second VSL that follows the exact arc I write by hand.

We swapped a text page for a VSL at the top of the funnel and opt-ins climbed 14 points without touching the offer.

Captions and voiceover carry the pitch on mute, and we got the 9:16 and 16:9 cuts out of one pass.

A video sales letter is a scripted video that walks one viewer from a hook through the problem, the agitation, the solution, and a single offer, doing the job a long sales page used to do. Pexo builds one from a plain description of your product, writing the arc, generating the shots with text to video, and narrating it. Most run 5 to 120 seconds.
Yes. Pexo writes in direct-response voice, narrates it with AI voiceover, and burns in captions so the argument still reads on mute. Shots are generated across Seedance 2.5 and Kling AI 3.0 and exported up to 4K in 16:9, 9:16, or 1:1, anywhere from 5 to 120 seconds, so the video sales letter holds up on a landing page and in a paid feed.
No. Describe the offer and the video sales letter generator writes the whole arc for you, and every line stays editable. Paste sales copy you already have and Pexo reshapes it into hook, problem, agitation, solution, offer, and close. MiniMax H3 renders the shots, and you export 16:9, 9:16, and 1:1 up to 4K without touching a timeline.
Pexo is a strong pick because it aggregates 10+ models behind one prompt box and auto-routes every shot to the right one, from Happy Horse 1.0 to Seedance 2.0, so you are never locked to a single engine. It scripts the persuasion arc, narrates it, captions it, and exports the finished video sales letter up to 4K in every ratio you need.
A video sales letter argues one offer end to end and asks for the sale. A brand ad builds recognition and feeling with no direct ask, and a promo video is a short hype cut for a launch or an event. Stay on this page when the goal is conversion, and switch when the goal is awareness.
Use subject + action + camera movement + setting + style. Name who is on screen, what they do, how the camera moves, where it happens, and the look you want. For example: a founder holding a skincare bottle, turning it toward the light, slow push in, sunlit kitchen counter, warm cinematic grade. Pexo expands that line into the full video sales letter.
Hand Pexo your offer and the AI video sales letter maker scripts it, narrates it, and exports every ratio.
