How to Post to Social Media via Muse

Posting to five different social apps by hand is nobody's favorite part of the day. If you use Muse, Meta's personal AI agent, you don't have to. Connect OneUp to Muse once, and you can draft, schedule, and publish social media posts just by asking in chat.

This guide walks through exactly how to post to social media via Muse, step by step.

Quick verdict

Muse on its own can only post to Facebook and Instagram; connect OneUp and the same chat can publish to every major network — and on a daily schedule, Muse can create content automatically or hold it in OneUp for a human to approve first.

• Muse alone: posts to Facebook and Instagram only — Meta's two networks
• Muse + OneUp: also reaches X, LinkedIn, TikTok, YouTube, Threads, Bluesky, Pinterest, Snapchat, Reddit, and Google Business Profile, so one request in chat can go out to every platform at once
• Two modes: by default Muse shows you the exact copy and posts only after you approve it; automated workflows can instead publish on schedule, or submit each post in OneUp for approval before it goes live

The catch: Muse on its own only posts to Facebook and Instagram

Out of the box, Muse's own social posting covers Meta's networks: Facebook and Instagram. That's it. If your audience is also on X, LinkedIn, TikTok, YouTube, Threads, Bluesky, Pinterest, Snapchat, Reddit, or Google Business Profile, Muse alone can't put a post there.

Connecting OneUp removes that limit. OneUp holds the connections to all of those networks, and Muse publishes through OneUp, so one request in chat can go out to every platform at once, not just the two Meta owns.

What you need

• A Muse account with access to connectors
• A OneUp account (the tool that actually publishes your posts)
• Your social accounts connected in OneUp: X (Twitter), Instagram, Facebook, LinkedIn, TikTok, YouTube, Threads, Bluesky, Pinterest, and Google Business Profile are all supported

Muse is the assistant you talk to. OneUp is the publishing engine behind it: your connected accounts, queues, and schedules live in OneUp, and Muse sends your approved posts there.

Step 1: Connect your social accounts in OneUp

In OneUp, connect each social account you want to post to. Group them into categories if you manage more than one brand or client, so you can post to a whole group at once later.

This is a one-time setup. Once an account is connected, Muse can post to it through OneUp without you logging into that platform ever again.

Step 2: Connect OneUp to Muse

Add the OneUp connector in Muse and link your OneUp account. If Muse asks for an API key instead, you'll find yours in OneUp under Settings → API and MCP → Generate API Key.

Linking the connector gives Muse permission to create posts in your OneUp account. Muse will still ask for your approval before anything is published, every time.

Step 3: Ask Muse to write your post

Now just describe what you want, the way you'd brief a social media manager:

• "Write a LinkedIn post announcing our new feature and post it to LinkedIn and X."
• "Turn this blog post into three social posts and schedule them across this week."
• "Draft an Instagram caption for this photo and schedule it for tomorrow at 9am."

Give Muse the topic, the platforms, and the tone. Add a link or an image if the post needs one, and mention any hashtags or mentions that must be included.

Step 4: Review and approve

Muse shows you the exact copy before anything goes out. Read it like you'd read any scheduled post: check the link, the hashtags, and that each platform's version makes sense. Ask for edits in plain language ("shorter", "less formal", "add the early-bird discount") until it's right, then approve it.

Nothing publishes without this step, so there's no risk of an AI draft going live unreviewed.

Step 5: Post now or schedule it

Tell Muse to publish immediately, or give it a date and time. Scheduled posts land in your OneUp calendar alongside everything else, so you can see, edit, or reschedule them in OneUp whenever you like.

Why post through a scheduler instead of asking Muse to open each app?

• One approval, every platform. A single post can go out to all your accounts at once, with per-platform variations.
• A real queue. Posts join your existing OneUp schedule instead of firing off at random times.
• Recycling. Evergreen posts can repeat automatically at the interval you choose.
• A calendar you can audit. Every AI-written post shows up in the same calendar as your manual ones.

Tips for better results

• Be specific about the hook. "Announce the launch" produces generic copy; "lead with the 40% time saving" doesn't.
• Ask for platform variations. A LinkedIn post and an X post about the same thing shouldn't read identically.
• Attach media deliberately. Instagram, TikTok, YouTube, and Pinterest need an image or video, so include one in your request.
• Batch it. Ask Muse to plan a week of posts in one conversation, approve them together, and let the schedule do the rest.

FAQ

Does Muse post without asking me first?
Only if you set it up that way. By default, no: Muse prepares the post, shows it to you, and it goes out only after you approve the exact copy. But if you run Muse on an automated schedule, you choose the mode per workflow: posts can publish automatically, or wait in OneUp for a human to approve them first. You're in control of which.

Which platforms can I post to via Muse?
Any platform connected in your OneUp account: X, Instagram, Facebook, LinkedIn, TikTok, YouTube, Threads, Bluesky, Pinterest, and Google Business Profile.

Which social networks can Muse post to by itself?
Only Facebook and Instagram. To post to X, LinkedIn, TikTok, YouTube, Threads, Bluesky, Pinterest, Snapchat, Reddit, or Google Business Profile from Muse, you need a publishing tool like OneUp connected.

Can Muse really create and post content every day without me?
Yes. Give Muse a standing brief and a daily schedule, and it will draft each day's post and send it to OneUp on its own. You choose whether posts publish automatically, or wait in OneUp for a human to approve them first.

Can I schedule posts for later, or only post immediately?
Both. Give Muse a specific date and time, or ask it to add the post to your queue.

What if I want to change a post after approving it?
Edit it in your OneUp calendar like any other scheduled post, or ask Muse to update it before its publish time.

Put Muse on autopilot: new content every day, with no manual work

Everything above also works without you starting the conversation. You can set Muse up to run on a daily schedule:

1. Give Muse a standing brief. The topics, the platforms, the tone, and your rules: always link the blog, never post prices, whatever matters to you.
2. Muse creates the content on schedule. Every day at the time you pick, Muse drafts that day's post and sends it to OneUp. No prompting, no copy-pasting, no dashboard.
3. You choose how it goes live:

• Post automatically. The post publishes at the scheduled time with no human involved. Best for formats you have already dialed in.
• Submit for approval. The post lands in OneUp as a draft waiting for approval. You (or a teammate) get notified, review the exact copy, edit it if needed, and approve it. Only then does it go out.

Most people start in approval mode, then move their proven formats to automatic posting once they trust the output. You can mix the two: automatic for routine posts, approval for anything new.

The short version

Connect your accounts in OneUp, link OneUp to Muse, then treat Muse like a social media manager who takes instructions in chat: draft, review, approve, and it posts or schedules for you. The dashboards are still there when you want them. You just may stop needing them.
