# AI Reel Generator

Type a topic and a small writing model, about 786 MB on first use, writes a short script in your browser. The voice and the vertical 720 x 1280 video are made there too, so nothing is uploaded. The model can invent facts, so check the script. It uses one of 5 free AI runs per rolling 24 hours.

Runs on your device

## How it works

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.

## Key facts

- **Output**: Vertical MP4 at 720 x 1280, plus the script as text
- **Length**: About 30 or 60 seconds
- **Uploaded**: Nothing, the script, voice and video are made on your device
- **Download**: About 786 MB writing model plus the voice, cached afterwards
- **Limit**: 5 free AI runs per rolling 24 hours, no sign up

## Common uses

- Test a content idea without filming anything.
- Turn a tip or a short how-to into a captioned vertical clip.
- Get a first script draft, then edit it and voice it again in Text to Video.

## Questions

### Does my topic stay private?

Yes. The writing model runs in your browser, so the topic is not sent anywhere. It is a small model and it can invent facts, names or numbers, so read the script and check every claim before you publish.

### Does it generate video clips or images?

No. The picture is either a dark background or the image you add, with captions on top. The only AI part is the script, and it can be wrong.

### Can I change the script it wrote?

Yes. Copy the script from the result, edit it, and paste it into Text to Video to make a new version with your wording.
