How to Build an AI Social Media Manager (Step-by-Step)

An AI social media agent turns one piece of content into platform-specific posts, schedules them, and reports back on performance — all through email. No switching between apps, no copy-pasting, no logging into five dashboards.

The agent also sends weekly performance digests:

When a post takes off, the agent flags it in Slack:

How it works

Create a social media agent at dashboard.carlyassistant.com (or email carly@usecarly.com and describe what you need). Connect your social accounts, design tools, and analytics — LinkedIn, Instagram, and Google Sheets cover most content workflows. The agent handles drafting, scheduling, and reporting immediately, and learns your brand voice and posting preferences over time. Full setup walkthrough: How to Create a Custom AI Email Agent.

How teams use a social media agent

  • Post new menu items — send a photo and a one-line description, and the agent drafts platform-specific posts for Instagram, X, and Facebook with the right tone and format for each, then schedules them at optimal times
  • Get a weekly performance report — agent pulls engagement data across all channels, identifies top-performing content, and recommends what to post more of
  • Repurpose customer reviews into social content — agent pulls standout Yelp and Google reviews, turns them into quote graphics for Instagram and testimonial posts for Facebook, and queues them up

Carly schedules, researches, and briefs you—so you can focus on what matters.

See what people say

"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.

Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.

On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
