AI Instagram captions
in your own voice.

Most AI caption tools sound like a brand account. CreaterOS writes from your instructions and what is actually in the photo, so captions read like you wrote them, and then it posts them for you.

Describe your voice once

Tone, language, length, emoji, hashtags, words to avoid. A few lines is enough; a few paragraphs works too.

Drop photos in Drive

CreaterOS looks at each photo when it is time to post and writes a caption for that exact image.

It posts with alt text

Every photo also gets an accessibility description, written automatically and added to the post.

What a good caption voice looks like

For example: “lowercase, warm and short. one sentence about the photo, then a question for followers. max 1 emoji. end with 3 hashtags.” The current month and year can be filled in automatically for seasonal captions.

Your words when you want them

Add a captions folder and put a text file named after the photo in it (photo-1.jpg → photo-1.txt): that caption is used as-is.
Leave the caption voice empty to turn AI captions off entirely.
Every run shows the caption and alt text that were posted, so you can see exactly what went out.

Questions

Does the AI see the photo?

Yes. The caption is written from the image itself plus your voice instructions, so it describes what is actually in the post. Videos are captioned from a frame of the video.

Is my content used to train AI?

No. CreaterOS uses a paid AI API under which the provider does not use your content to improve its models.

Can it write in other languages?

Yes. Write the caption voice in the language you want, or ask for a mix, and captions follow it.

Drop it in Drive.
It posts itself.

CreaterOS puts your Instagram on autopilot: drop photos and videos into a Google Drive folder, pick your posting times, and it writes captions in your voice, adds alt text, turns photos into Reels with copyright-safe music, and publishes on schedule through the official Instagram API.
