# Automate your Instagram posts with an AI agent

> Connect an AI agent to posthell and, with Publishing enabled, it can publish Instagram text updates for you. Autonomous and unlimited, with an honest limit: the agent posts text, not Reels or images.

Most founders are not full-time Instagram creators, and the part they neglect is the writing, not the photography. With an agent connected to posthell and publishing enabled, your agent can shape a note into an Instagram-native text caption and publish it on its own, unlimited and free. Be clear on the boundary: the agent surface is text-only right now, so it handles text captions and announcements, not the Reel, carousel, or photo itself. For visual posts you still use the composer; the agent keeps the words flowing.

## What you get

### Captions and updates, shipped for you

The agent writes a caption that carries on the feed (its own phrasing, its own line breaks) and can publish it autonomously, so your Instagram presence does not go quiet between photo shoots.

### Honest about what it posts

The agent posts text. It does not publish Reels, carousels, videos, or images on your behalf, because the agent surface is text-only for now. No overclaiming, so no surprises.

### Unlimited and never metered

Instagram is free to serve, so an agent posting to it costs nothing on every plan. Only X is metered.

### Focus where you are growing

The agent can read your 7-day follower growth per network, so if Instagram is pulling ahead it knows to keep posting there rather than spreading thin.

## Frequently asked questions

### Can an AI agent post to Instagram automatically?

Yes, for text posts, once you enable Publishing on the agent's key. The agent publishes Instagram text captions and updates on its own. It does not post Reels, carousels, or images, because the agent surface is text-only for now.

### Can the agent post my Reel or a photo carousel?

No. Reels, videos, carousels, and images are not something the agent publishes today. Use the posthell composer for visual posts. The agent handles writing and publishing text.

### Is automated Instagram posting limited?

No. Instagram is unlimited on every plan, and an agent publishing text to it is never metered. Only X costs credits.

### Do I have to approve each Instagram post?

Not if you enabled Publishing on the key: the agent publishes text posts directly. If you would rather review first, leave the key on draft-only and the agent queues drafts for you instead.
