# How to make a reel with AI from a single topic

Updated 2026-11-09

To make a reel with AI, give a small language model a topic and let it write a short script, then voice and caption that script. AI Reel Generator does this entirely in your browser, and nothing is uploaded. The vertical 720 x 1280 video is made on your device. You download the MP4 and the script.

## Make a reel in three steps

All you supply is an idea. The tool writes the first draft.

1. Type your topic and choose about 30 or about 60 seconds.
2. Pick a language and voice, and add a background picture if you like.
3. Make the reel, then download the MP4 and the script.

## What the AI does and does not do

The AI part is the script. A small writing model (Qwen2.5-0.5B, about 786 MB, downloaded on first use) writes it in English in your browser from your topic and target length. For a voice in another language, a translation model of about 632 MB translates the script on your device. It can invent facts, so check the script before you post. The video itself is captions on a dark background or on the picture you add. No clips or images are generated.

## What leaves your device

Nothing. The topic, the script, the voice and the video all stay in your browser. The models download once and are kept. Each run counts toward the 5 free AI runs shared across tools in any rolling 24 hours, with no sign up.

## Write a topic that gives a better script

A broad topic such as fitness gets a broad script. A narrow one such as three stretches for people who sit all day gives the model one point to make and a reader to speak to. Name the audience and the single thing they should take away.

Check the first line of the draft before anything else. A reel starts playing the moment it loads, so the opening sentence should say what the viewer gets.

## Edit the script before you post

A first draft rarely sounds like you. Copy the script from the result and change the wording. Then paste it into Text to Video to voice and caption your own version.

Pick a background picture that fits the topic. Plain dark works for a tip, but a photo gives the captions something to sit on.

## Questions

### How long is the reel?

About 30 or about 60 seconds, whichever you choose. The length is a target for the script.

### What size is the video?

Vertical, 720 x 1280, as an MP4.

### Can I get the script as text?

Yes. The result includes the script as text next to the MP4.
