How to Build a Free AI Agent for X (Twitter) Automated Content Creation

A free AI agent for X (Twitter) is a no-code automation workflow that uses Tavily AI for real-time research, Zapier Central for logic, and Buffer to bypass the expensive X API fees. This setup allows you to research trending news, generate concise tweets, and schedule posts automatically without a paid developer account.

The "Buffer Bypass": Why This Method Works

Most people stop automating for X because the API pricing is out of reach for beginners.

The Specialist Insight: By routing your Zapier automation through Buffer’s free tier, you can post to X without paying for a direct API connection.

The Tech Stack: * Zapier: The "brain" (If This, Then That).

Tavily AI: The "researcher" (hallucination-free AI search).

Buffer: The "delivery vehicle" (free scheduling).

Step-by-Step Guide to the Workflow

Set the Trigger (Schedule by Zapier) Set your agent to wake up at a specific time (e.g., 2:00 PM daily). This ensures consistent "activity" on your profile.
Real-Time Research with Tavily AI Instead of generic GPT knowledge, Tavily searches the live web for news from the last 48 hours.

Prompt Tip: Tell the agent to find "AI marketing analytics news" and limit the output to two short paragraphs (under 150 characters) to avoid the "Show More" truncation on X.

Content Generation & Quality Control The agent processes the news and drafts a tweet. In the video, we saw it catch the Salesforce/Qualified acquisition news instantly.
The "Human-in-the-Loop" Queue Instead of "Auto-Publishing," send the draft to the Buffer Queue. This allows you to review, edit, or approve the tweet before it goes live, ensuring your brand voice stays intact.

Pricing: How is this "Completely Free"?

As a specialist, I focus on ROI. Here is the free-tier breakdown for this build [08:22]:

Zapier: Up to 400 activities/month on the free plan.
Tavily AI: 1,000 free API credits per month.
Buffer: 3 social channels on the free tier.
