An AI Agent That Writes Your Blog and Posts It Everywhere

An autonomous agent researches a topic, drafts a blog post, tailors it for each channel, waits for human sign-off, then publishes to your blog, LinkedIn, Facebook, X, and Instagram.

Content marketing stalls because writing, formatting, and posting across five channels every week is a grind. This example shows a content agent that runs the whole pipeline: research, a full blog draft, an on-brand image, per-channel versions, a brand and policy check, and one human approval before anything goes public. Then it publishes everywhere. Watch it work below.

Watch the Agent Work

A weekly topic comes in. The agent researches, drafts a post, tailors it per channel, pauses for human approval, then publishes across five channels.

Before / after

Manual: roughly half a day to write, format, and post across five channels.

With the agent: minutes of review, then one approval click to publish everywhere.

What the Agent Does

Researches and drafts

It gathers current points on a topic and writes a full, structured blog post with title, headings, and meta description, ready to edit.

Stays on brand

It writes in your voice from a style guide and reuses your approved messaging, so the output sounds like you, not generic AI.

Tailors per channel

One idea becomes a LinkedIn post, an X thread, a Facebook caption, and an Instagram caption with hashtags, each formatted for its platform.

Checks brand and policy

Tone, claims, and banned-word rules are enforced before publishing, so nothing off-brand or risky goes out.

Waits for approval

Nothing publishes until a person approves it. You review once and the agent handles the rest.

Publishes and schedules

It posts to your CMS and each social platform through their APIs, or schedules them, and logs every post.

How We Build It

1

Scope the pipeline

We define your channels, formats, posting cadence, brand voice, and exactly what a person must approve before publishing.

2

Build the integration layer

We connect the agent to your CMS and social accounts through their APIs (or a scheduler like Buffer), with scoped access.

3

Guardrails and evals

We encode your brand and compliance rules and test drafts against them, so the agent's output is consistently safe to publish.

4

Human-in-the-loop

We add a one-click approval step with previews of every channel version, so review takes minutes.

5

Deploy and monitor

We schedule the run, track what published, pull back engagement, and tune the prompts and cadence over time.

Frequently Asked Questions

Does it post automatically without us checking?
Only if you want it to. By default, nothing publishes until a person approves the drafts. You can also let routine posts go out automatically and keep approval for specific channels or claims.
Which platforms can it publish to?
Your blog or CMS plus LinkedIn, Facebook, X (Twitter), and Instagram, through their official APIs or a scheduler. We can add other channels like a newsletter or TikTok captions.
Will the content sound like our brand?
Yes. We build it from your style guide, tone, and approved messaging, and the brand check blocks anything off-voice. You always review before it publishes.
Can it reuse one idea across channels?
That is the point. The agent writes the blog post once, then produces a tailored version for each channel, formatted correctly, instead of copy-pasting the same text everywhere.
What does it cost and how long does it take?
A content and social publishing agent typically runs $12,000 to $30,000 and takes 5 to 10 weeks, depending on the channels and how much brand and compliance logic is involved. We scope each project individually.
