# Instagram Caption Generator

The Instagram Caption Generator writes up to 10 caption ideas from a short description of your post, in a tone you choose such as friendly, funny or professional. A small model runs in your browser, so what you type never leaves your device. It uses one of 5 free AI runs per rolling 24 hours. Copy any caption.

Runs on your device

## How it works

1. Describe your post in the What is your post about box, including details you want mentioned.
2. Choose a Tone and set How many captions, from 1 to 10.
3. Press Write captions and wait for the model (the first run downloads about 786 MB).
4. Press Copy beside the caption you like, or Copy all, then edit it to sound like you.

## Questions

### Is the text I enter sent to a server?

No. A small writing model runs in your browser, so the text you type never leaves your device. Each run counts toward 5 free AI runs shared across ToolSugar in any rolling 24 hours, with no sign up. The first run downloads about 786 MB, cached afterwards.

### Will it invent facts about my post?

It is told to use only the details you give. Still read every caption, because a small model can invent details, and add prices, dates or links yourself.

### Why are my captions all different lengths?

Each one is a separate idea written to be distinct. Instagram allows up to 2,200 characters, and you can check a caption's length with the Character Counter.

### What happens when the daily limit is reached?

A message says when your next run opens and keeps your description in the box. The limit is 5 runs in any rolling 24 hours, shared with the other AI tools.
