Generate AI photos with Gemini & auto-post to FB, Instagram & X with approval

Social Media Foto Creation Bot with Approval Loop

Create & Share AI Photos with Telegram, Gemini & Post to Facebook, Instagram & X

Description This n8n workflow turns your Telegram messenger into a complete AI Photo Content Pipeline. You send your photo idea as a text or voice message to a Telegram bot, collaborate with an AI to refine the prompt and social media caption, let Gemini generate the image, and then automatically publish it after your approval to Facebook, Instagram, and X (Twitter) – including status tracking and Telegram confirmations.

What You Need to Get Started

This workflow connects several external services. You will need the following credentials:

• Telegram Bot API Key
  • Create a bot via BotFather and copy the bot token.
  • This is used by the Listen for incoming events and other Telegram nodes.
• OpenAI API Key
  • Required for Speech to Text (OpenAI Whisper) to transcribe voice notes.
  • Used by the AI Agent model (OpenAI Chat Model) for prompt creation.
• Google Gemini API Key
  • Used by the Generate an image node (model: models/gemini-2.5-flash-image) to create the AI image.
• Google Drive & Sheets Access
  • The generated image is temporarily stored in a Google Drive folder (Upload image1) and later retrieved by Blotato.
  • Prompts and post texts are logged to Google Sheets (Save Prompt & Post-Text) for tracking.
• Blotato API Key
  • The layer for social media publishing.
  • Uploads the image as a media asset (Upload media1) and creates posts for Facebook, Instagram, and X.

How the Workflow Operates – Step by Step

1. Input & Initial Processing (Telegram + Voice Handling)

This phase receives your messages and prepares the input for the AI.

The output of this stage is always a clean text string containing your image idea.

2. AI Core & Refinement Loop (Prompt + Caption via AI)

Here, the AI drafts the image prompt (for Gemini) and the social media caption (for all platforms) and enters an approval loop with you.

3. Content Generation & Final Approval

Once the prompt and caption are set, the image is created and sent to you for final approval before publishing.

4. Upload & Publishing (Blotato)

After final approval, the image is uploaded to Blotato, and post submissions for the social media platforms are created.

5. Status Monitoring & Retry Loops (X, Facebook, Instagram)

An independent loop runs for each platform, polling Blotato until the post is either published or failed.

🛠️ Personalizing Your Content Bot

The workflow is highly adaptable to your personal brand and platform preferences:

1. Tweak the AI Prompt & Behavior:
   • Where: In the AI Agent node, within the System Message.
   • Options: Change the tone (casual, professional, humorous) and the level of detail required for the prompt generation or the social media captions.
2. Change Gemini Model or Image Options:
   • Where: In the Generate an image node.
   • Options: Swap the model or adjust image options like Aspect Ratio or Style based on Gemini's API capabilities.
3. Modify Which Platforms You Post To:
   • Where: In the Blotato nodes: Create instagram Post, Create x post, Create FB post.
   • Options: Disable or delete branches for unused platforms, or add new platforms supported by Blotato.
