# Post to Instagram with Claude or ChatGPT (2026 Setup)

> To post to Instagram with Claude, connect your Instagram business or creator account to RobinReach, then add RobinReach to Claude as a connector at https://robinreach.com/mcp/v1/messages. Claude can then look at your photos, write captions and alt text, and schedule posts, carousels, Reels and Stories at your best times. It can also answer comments and set up Auto DM, so people who comment a keyword get your link in a DM. The same works in ChatGPT and other AI apps, on the Bloom, Thrive and Scale plans.

## Example

User: Caption the three photos I uploaded today as one carousel, add alt text, and post it on Friday at our best time.

What Claude did in RobinReach:
- `media_search`: Found the three photos from today
- `media_view`: Looked at each photo
- `account_audience_best_times`: Friday at 18:30 is your best slot
- `posts_validate`: Checked the carousel and caption against Instagram's rules
- `posts_create`: Scheduled the carousel for Friday at 18:30

Claude: Scheduled for Friday at 6:30 pm, when your followers are most active. The caption opens with the glaze close up, and each photo has its own alt text. Want me to add a first comment with your hashtags?

## What Claude can do on Instagram

- **Feed posts and carousels.** One photo or a swipeable carousel, with a caption and alt text written after Claude has looked at the images.
- **Reels.** Vertical videos with a cover image, and Trial Reels that show to non followers first.
- **Stories.** Photo and video Stories, scheduled like any other post.
- **Collaborators and location.** Invite collaborators and tag your location so local people find the post.
- **Comments.** Read new comments, reply in your voice and keep the conversation going.
- **Auto DM.** When someone comments a keyword, they get a DM with your link, set up from the chat.
