Generate AI Photos with Gemini & Auto-Post to Facebook, 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.

Node Name	Role in Workflow
Listen for incoming events	Telegram Trigger node that starts the workflow on any incoming message.
Voice or Text	Set node that structures the incoming message into a unified text field.
A Voice?	IF node that checks if the message is a voice note.
Get Voice File	If voice is detected, this downloads the audio file from Telegram.
Speech to Text	Uses OpenAI Whisper to convert the voice note into a text transcript.

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.

Node Name	Role in Workflow
AI Agent	Central logic agent. Creates a videoPrompt (used for image generation) and socialMediaText based on your idea, and asks for feedback.
OpenAI Chat Model	The LLM backing the agent (e.g., GPT-4.1-mini).
Window Buffer Memory	Stores recent turns, allowing the agent to maintain context during revisions.
Send questions or proposal to user	Sends the AI's suggestion for review back to you.
Approved from user?	IF node that checks if the output is the approved JSON (meaning you replied with "ok" or "approved").
Parse AI Output	Code node that extracts the videoPrompt and socialMediaText fields from the agent’s final JSON output.

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.

Node Name	Role in Workflow
Inform user about processing	Telegram node to confirm: "Okay. Your image is being prepared now..."
Save Prompt & Post-Text	Google Sheets node that logs the videoPrompt and socialMediaText.
Generate an image	Gemini node that creates the image based on the videoPrompt.
Send a photo message	Sends the generated image to Telegram for review.
Send message and wait for response	Telegram node that waits for your response to the image (e.g., "Good?" / "Approve").
Upload image1	Temporarily saves the generated image to Google Drive.
Download image from Drive	Downloads the image back from Drive.
If1	IF node that checks if the image was approved in the previous step (approved == true).

4. Upload & Publishing (Blotato)

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

Node Name	Role in Workflow
Upload media1	Blotato Media node. Uploads the approved image as a media asset and returns a public url.
Create instagram Post	Creates an Instagram post using the media URL and socialMediaText.
Create x post	Creates an X (Twitter) post using the media URL and socialMediaText.
Create FB post	Creates a Facebook post using the media URL and socialMediaText.

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.

Node Name	Role in Workflow
Wait, Wait1, Wait2	Initial pauses after post creation.
Check Post Status, Get post1, Check Post Status1	Blotato Get operations to fetch the current status of the post.
Published to X?, Published to Facebook?, Published to Instagram?	IF nodes checking for the "published" status.
Confirm publishing to X, Confirm publishing to Facebook, Confirm publishing to Instagram	Telegram nodes that notify you of successful publication (often including the post link).
In Progress?, In Progress?1, In Progress?2	IF nodes that check for "in-progress" status and loop back to the Wait nodes (Give Blotat other 5s).
Send X Error Message, Send Facebook Error Message, Send Instagram Error Message	Telegram nodes that notify you if a failure occurs.

🛠️ 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.
