How to Get an AI to Write and Publish Blog Posts for You

Last updated: March 26, 2026

Writing blog posts consistently is one of those tasks everyone knows matters, but almost no one has time to do properly. You need to research topics, write engaging content, optimize for SEO, format everything correctly, upload images, and finally publish.

AI agents can now handle the entire blog writing and publishing workflow for you—not just generating a draft you have to clean up and manually post, but researching, writing, formatting, and publishing finished posts directly to your site while you do other work.

Here's how to set it up so you can message an AI agent "write a blog post about home office productivity tips" and wake up to a published, SEO-optimized post live on your site.

What can an AI agent actually do for your blog?

An AI agent like Tommy.app can handle every step of blog content creation from research to publishing. Here's what that looks like in practice:

• Research your topic: The agent searches the web for current information, reads top-ranking articles, and identifies what people are asking about your topic
• Write the full post: Creates an 800-1,500 word article in your writing style, with proper heading structure, paragraphs, and transitions
• Optimize for SEO: Includes your target keywords naturally, adds meta descriptions, structures headings for search engines, and includes FAQ sections
• Format correctly: Applies your blog's styling, handles HTML/markdown conversion, and makes everything look clean on your site
• Publish directly: Logs into your blog platform and publishes the post live (or saves as draft for your review)
• Remember past posts: Knows what you've published before so it doesn't repeat topics or contradict old posts

A Tommy agent wrote and published 7 blog posts about home renovation tips in 12 minutes for a contractor who hadn't updated his site in two years. All 7 posts are ranking on Google's first page within three weeks.

How do I connect an AI agent to my blog platform?

The setup depends on what blogging platform you use. Here's how it works for the most common platforms:

WordPress (most common)

WordPress has an Application Password feature that lets your AI agent publish posts without giving it your main password. You create an application password in your WordPress admin panel (Users → Profile → Application Passwords), then give that credential to your AI agent.

With Tommy.app, you just message your agent: "Connect to my WordPress at myblog.com with this application password: [paste password]" and it saves the connection. From then on, you can tell it to write and publish directly.

Ghost, Webflow, and static site generators

These platforms usually have API keys you can generate. Your AI agent uses the API to create and publish posts. The setup is similar—you give your agent the API credentials once, and it remembers them.

Custom sites or direct server access

If you host your own site, you can give your AI agent SSH access or FTP credentials so it can write HTML files directly to your server. Tommy agents can handle this—they'll write the post as HTML matching your site's design and upload it to the right folder.

Security note: Use read-only credentials wherever possible, or create a dedicated user account with limited permissions just for your AI agent. That way, if something goes wrong, your agent can't accidentally break your whole site.

How do I tell my AI what to write about?

Once your agent is connected to your blog, writing posts is as simple as sending a message. You don't need to write detailed prompts or instructions—just describe what you want like you're talking to a person.

Here are real examples of messages people send to their Tommy agents:

• "Write a blog post about choosing the right workout split for beginners. Target keyword: beginner workout split. Make it practical and honest, not hyped-up gym bro stuff."
• "Write 5 neighborhood guide posts for Key West—one each for Old Town, New Town, Duval, Truman Annex, and Bahama Village. Include what it's like to live there, average home prices, and best restaurants. I'm a real estate agent."
• "Write a blog post about how to save on car insurance without sacrificing coverage. Target people searching for 'how to lower car insurance'. Write in my style—check my past posts for tone."

Your agent asks clarifying questions if it needs more detail, then gets to work. You'll get a message back a few minutes later saying "Published: [post title] at [URL]" with a link to the live post.

Will the blog posts sound like a robot wrote them?

Not if you use a good AI agent like Tommy.app that's powered by Claude. The key is training your agent on your writing style and giving it real context about your audience.

Here's how to make AI-written blog posts sound like you:

• Share past posts: Message your agent links to 3-5 of your existing blog posts and say "match this tone and style." The agent learns how you write and applies it to new posts.
• Describe your audience: Tell your agent who you're writing for. "I'm a dog groomer writing for pet owners in Florida who want to keep their dogs clean between appointments" gives context that shapes the whole post.
• Edit once and the agent remembers: If your agent writes something too formal or too casual, tell it to adjust. "Make it more conversational" or "sound more professional" works, and it remembers for future posts.
• Avoid generic keywords: Don't just say "write about home insurance." Say "write about why Florida homeowners are getting dropped by State Farm and what their options are now." Specific topics lead to specific, helpful posts—not generic AI slop.

The posts read naturally because modern AI agents research real information from the web and synthesize it, rather than just regurgitating training data. Your agent is reading current sources and writing based on what it finds, not templating content.

Can AI write blog posts that rank on Google?

Yes, but only if the AI agent is built to optimize for search engines—not all AI tools do this automatically. Tommy agents are specifically trained to structure posts for SEO.

Here's what your AI agent needs to do for posts to rank:

• Research keywords naturally: Your agent should search for what people are actually asking, not just stuff keywords into paragraphs. Google's algorithms in 2026 prioritize helpful content over keyword density.
• Use proper heading hierarchy: H1 for the title, H2 for main sections, H3 for subsections. Search engines use this structure to understand your post.
• Write longer, detailed posts: Google favors comprehensive content. Posts under 600 words rarely rank. Your agent should aim for 1,000-1,500 words with real depth.
• Include FAQ sections: These often get pulled into Google's "People Also Ask" boxes. Your agent should add 3-5 common questions with clear answers at the end of each post.
• Optimize meta descriptions: Your agent needs to write compelling meta descriptions under 155 characters that make people want to click your result.
• Link internally: Your agent should link to your other relevant posts. This keeps readers on your site longer and helps Google understand your content structure.

A real estate agent used his Tommy agent to write 5 neighborhood guides for Key West. All 5 posts hit Google's first page within 2 weeks because the agent researched what people actually search for (not what the agent guessed) and wrote detailed, helpful content.

How much does it cost compared to hiring writers?

Freelance blog writers charge $100-500 per post depending on length and quality. If you publish 2 posts per week, that's $800-4,000 per month. Most small businesses can't afford that consistently.

Tommy.app costs $1 for a 3-day trial, then $49/month for the Starter plan (which includes unlimited blog posts) or $99/month for the Pro plan (which adds priority speed and more advanced capabilities). Your agent can write as many posts as you need—5 per week, 20 per month, whatever your content strategy requires.

The math is simple: One month of Tommy.app costs what you'd pay a freelancer for one blog post, but your Tommy agent writes unlimited posts, publishes them automatically, remembers your past content, and works 24/7.

Do I still need to review the posts before they go live?

That depends on how much control you want and how much you trust your agent. Most people start by having their agent save posts as drafts, then review and publish manually. After a few weeks, when they see the quality is consistent, they switch to automatic publishing.

With Tommy.app, you can set publishing preferences:

• Draft mode: Your agent writes the post and saves it as a draft. You review, make edits if needed, and click publish in your blog platform.
• Auto-publish mode: Your agent writes and publishes immediately. You get a notification with the live URL.
• Approval mode: Your agent writes the post, sends you the full text in Telegram, and waits for you to say "publish it" before going live.

Most people use approval mode at first, then switch to auto-publish once they're confident their agent understands their style and standards.

What if I want to edit something after it's published?

Just message your agent with the change. You can say "In the workout split post, change the rep ranges in the PPL section to 8-12 instead of 6-10" and your agent will find the post, make the edit, and update the live version.

Your agent remembers every post it's published, so you can refer to posts by topic or title and it knows what you're talking about. You don't need to log into your blog platform to make small tweaks—just tell your agent what to fix and it handles it.

Can my AI write posts in different formats?

Yes. You can tell your agent what format you want and it adapts. Common formats people use:

• How-to guides: Step-by-step instructions with numbered lists
• Listicles: "10 best X for Y" style posts
• Comparison posts: "Product A vs Product B" with tables
• Case studies: "How I did X and got Y result"
• Ultimate guides: Long-form comprehensive posts covering everything about a topic
• Opinion pieces: Editorial-style posts with your perspective

You can even mix formats. One fitness coach has his Tommy agent write a mix of workout guides (how-to format), supplement comparisons (comparison format), and client transformation stories (case study format). The agent rotates through formats automatically based on the topic.
