Twitter content automation with Gemini AI for tweets, images, and engagement

## | N8N Workflow | AI-Powered Twitter Automation with Content Generation and Engagement 🚀

This n8n template automates Twitter (X) activity — from generating tweet content with AI to engaging with posts and even sending DMs — all powered by Google Gemini or OpenRouter AI.

It’s designed for creators, marketers, brands, and agencies who want to automate social media presence with authentic, on-brand AI content and engagement.

How It Works

• The workflow begins with a form trigger, where users input their topic, tone, and action type (Tweet, Engage, or DM).
• Those inputs are passed into Workflow Configuration, which sets key parameters like max tweet length and model URLs. Depending on your chosen action:
• Post Tweet: AI generates a tweet under 280 characters and can attach an image.
• Engage with Posts: AI can like, retweet, or reply to niche-relevant content.
• Send Direct Message: AI drafts a personalized DM for outreach or networking.
• If your workflow includes visuals, the AI Agent - Create Image From Prompt node builds a detailed image prompt (based on your topic and instructions) and sends it to Google Gemini or other image APIs.
• The HTTP Request - Create Image node generates a custom image via an external model (default: Pollinations.ai).
• Finally, all tweet text and image data merge together in Merge Tweet Text and Image, before being posted directly via the Create Tweet node.

How To Use

• Download and Import the JSON workflow into your n8n interface.
• Set up the following credentials:
• OpenRouter API for text generation.
• Google Gemini (PaLM) for chat and image prompt creation.
• Twitter OAuth2 API for posting and engagement actions.
• Configure your form input fields (Topic, Tone, Action, Instructions).

Enable or disable the nodes you want:

• Create Tweet → To post automatically.
• Twitter Engagement Tool → For likes/retweets/replies.
• Twitter DM Tool → For automated DMs.
• Trigger the Twitter Content Form via n8n’s web interface.
• Enter your content preferences and submit.
• The workflow generates your tweet text, optionally creates a matching image, and posts or saves it automatically.

Requirements

A Twitter Developer Account (with OAuth2 credentials). A Google Gemini or OpenRouter account with text and image model access. (Optional) Connection to Pollinations or another AI image generation API.

How To Customize

• Update “Fields – Set Values” node to change:
• Default image size (1080 × 1920 px).
• Model name (e.g., “flux”, “turbo”, “kontext”).
• Modify Workflow Configuration to tweak AI parameters like:
• imageGenerationChance (default: 0.3).
• maxTweetLength (default: 280).
• Replace Google Gemini Chat Model with any supported model such as OpenAI GPT-4 or Mistral.
• Adjust AI Agent - Create Image From Prompt system message for your preferred image style or guidelines.
• Toggle which Twitter actions are active — Post, Engage, or DM — to tailor automation to your goals.
