How to Automate Social Media Posts with AI: Step-by-Step

Why Automate Social Media Posts?

Keeping an active presence on several networks is one of the most time-consuming jobs in marketing. Businesses want to post regularly on Facebook, Instagram, X, LinkedIn, TikTok and YouTube, and each has its own formats, limits and audience expectations.

An AI agent helps by writing a version of each post for each network, making a matching picture, and publishing to all of them from one place. Instead of writing and designing every post yourself, you describe what you need, review the drafts, and approve.

Step 1: Connect Your Social Media Accounts

The first step is connecting your social media accounts. Connections use OAuth: you sign in on the network's own site and approve access, so your password never passes through AutomateSocials. The token the network issues is stored encrypted.

You can connect Facebook pages, Instagram business or creator accounts (through the Facebook page they are linked to), X, LinkedIn profiles and company pages, TikTok, and YouTube channels (Shorts). Open Project setup → Connected accounts, press the network's button, approve on the network's site, and you land back in the app. Each project holds one live connection per network.

Step 2: Set Up Your Project and Knowledge Base

Give the project your website first. The agent reads it and fills in your project profile: what you do, who it is for, your keywords, the language you write in and your tone. You correct it once. Then add the material the agent should write from, so posts sound like you rather than generic filler.

The knowledge base takes web pages, PDFs and text. Good entries include product descriptions, articles you have written, customer stories, and the facts customers ask about. When the agent writes, it searches the knowledge base for passages that fit and uses them.

• •Upload PDFs or text files with brand and product information
• •Paste website URLs; the readable text is taken, and a page with almost no text is refused rather than stored empty
• •Set your tone, visual style and content instructions under Project setup → Brand & voice
• •Include key messages, offers and the details customers ask about most

Step 3: Write Posts with the Agent

With your accounts connected and your knowledge base filled, you can start. Describe what you want in the chat and the agent writes it, saving each post as a numbered draft under Posts so you can refer to it later ("make #7 shorter").

For example, type "Write a post about our new product launch for LinkedIn and X" and the agent writes a version for each network. It pulls product details from your knowledge base and adapts the wording to each network: up to 280 characters for X, a fuller version for LinkedIn.

You can also ask for a matching picture: "make a picture for this post". The default model, Nano Banana, costs 1 credit; Nano Banana 2 (3 credits) and Nano Banana Pro (6 credits) give more detail. Your project's visual style is applied to every picture, and the price is quoted before the picture is made.

Step 4: Publish or Schedule

When the draft is right, tell the agent what to do with it. It shows exactly what will go where and asks you to confirm. You have three options: publish now, schedule for a date and time you name, or put the post in the next free slot of your weekly publishing schedule.

Each network's limits are checked before publishing: X's 280 characters, Instagram's need for a picture or video, TikTok's lack of text-only posts, YouTube's need for a vertical or square video of up to three minutes. Where a version is too long, the agent tells you instead of cutting silently, and can shorten it or turn it into an X thread. Scheduled posts can be moved, edited or cancelled until they go out.

Step 5: Set Up Recurring Workflows

For work that repeats, set up a workflow: a list of steps and a schedule. A step can read a source (a web page, another account's feed or your knowledge base), write for the networks you choose, make a picture, then save a draft or publish. For example: "every weekday at 8, read our blog's newest article and publish a LinkedIn post about it at 9".

Workflows run daily, weekly or once, in your project's time zone. Each run is priced up front and does not start if your credits would not cover it, and every step of every run is recorded. A workflow that publishes does so without asking each time, because you approved it when you started it; end it with "save a draft" if you want to review every post, and pause it whenever you like. To see how the posts did, ask the agent: every post is measured over its first month.
