This workflow turns any Telegram bot into an AI-powered social media command center for photos, videos and voice notes.

video demo

From one Telegram chat you can:

  • Send a photo and auto-post it to Instagram, TikTok and Pinterest with AI captions.
  • Send a video and:
    • Let AI generate titles + descriptions and upload it to TikTok, Instagram and YouTube.
    • Use /thumb to generate 4 custom thumbnails with Nano Banana Pro.
    • Use /edit ... to run FFmpeg edits (cut, mute, resize, speed, etc.) via Upload-Post FFmpeg jobs and get the edited video back in Telegram.
  • Send a voice note and turn it into posts for LinkedIn, X (Twitter) and Threads, then auto-publish.
  • Keep human approval in the loop: every caption or text post is shown in Telegram for you to accept before publishing.

Out of the box, the captions and long descriptions are optimized for Spanish (es-ES), but you can easily change the prompts to any language or brand voice.

What You Can Do From Telegram

1. Photo → Instagram, TikTok & Pinterest

Just send a photo (or image as document) to your Telegram bot:

  • The workflow downloads the photo from Telegram.
  • Gemini 2.5 Flash analyzes the image plus your caption/text (if any).
  • An AI Agent generates platform-specific descriptions for:
    • TikTok (short hook, 90 chars)
    • Instagram
    • Pinterest (title + description)
  • You receive a message in Telegram with all the proposed descriptions.
  • You approve or reject with inline buttons.
  • On approval, Upload-Post publishes the photo to:
    • Instagram
    • TikTok
    • Pinterest (to the board you configured)
      and sends back a status message with success flags, post URLs and error messages.

2. Video → TikTok, Instagram & YouTube (no commands)

If you send a video with no special caption:

  • The workflow treats it as a standard video post.
  • It fetches the file from Telegram.
  • Gemini 2.5 Flash analyzes the video and describes its content.
  • An AI Agent turns that description + your caption into:
    • TikTok description
    • Instagram description
    • YouTube title + description
  • You get a Telegram message with the three platform descriptions to review.
  • Once you approve:
    • It shows “Uploading…” in Telegram.
    • The video is sent to Upload-Post, which uploads to TikTok, Instagram and YouTube with the generated text.
    • Finally, you receive an upload report for each platform (success, URL, error message).

3. /thumb → AI Thumbnails for Your Video (Nano Banana Pro)

If you send a video with caption exactly /thumb:

  • The workflow downloads the video.
  • Gemini 2.5 Flash generates a long, SEO-rich description in Spanish of everything that happens in the video.
  • A second AI Agent uses that detailed description to create 3 concepts:
    • Each concept has: title, description, and a full prompt_thumbnail (Spanish, single line) specially crafted for Nano Banana Pro.
  • In Telegram you see the 3 concepts (titles) and select:
    • 0, 1, 2 or “create new”.
  • Once you choose a concept:
    • The prompt is sent to Nano Banana Pro (fal-ai/nano-banana-pro/edit) with your reference face image (configurable).
    • Nano Banana Pro generates 4 thumbnails (16:9).
    • The workflow downloads the 4 images and sends them back to you in Telegram as photos so you can pick and use your favorite in your YouTube/Upload-Post pipeline.

Use /thumb whenever you already have the video and just want killer thumbnails generated with AI.

4. /edit … → Natural-Language FFmpeg Video Editor

If you send a video with a caption starting with /edit, for example:

  • /edit cut the first 3 seconds and remove the audio
  • /edit crop to vertical 9:16 and speed up x1.5
  • /edit blur the background and keep the subject centered

The workflow behaves as a text-to-FFmpeg command generator:

  • An AI Agent (powered by Gemini) reads your /edit instructions.
  • It generates a safe FFmpeg command in JSON format:
    • Always uses ffmpeg -y
    • Uses {input} and {output} placeholders
    • No semicolons and no dangerous shell characters
  • The workflow then:
    • Downloads the original video from Telegram.
    • Calls Upload-Post FFmpeg jobs API with the video and the generated full_command.
    • Polls the job status until it’s finished.
    • Downloads the processed (edited) video.
    • Sends the edited video back to you in Telegram with a simple sendVideo node.

This makes Telegram a front-end for a remote FFmpeg engine: you describe the edit in natural language, and the workflow handles all the FFmpeg complexity.

Note: The edited video is returned to Telegram; if you want to auto-post it, simply send the new video again without /edit so it goes through the normal multi-platform publishing path.

5. Voice Notes → LinkedIn, X & Threads (Text Posts)

For voice messages:

  • The Telegram Trigger detects message.voice.
  • The workflow downloads the audio file.
  • OpenAI Whisper transcribes the recording.
  • An AI Agent turns the transcription into:
    • A LinkedIn post (Spanish, long-form dev/creator style, based on your examples).
    • A Threads post (Spanish, up to ~500 chars).
    • A Tweet / X post or thread (English, using hooks + hashtags like #n8n, #automation, #dev).
  • In Telegram you see a preview message with the suggested copy for Threads, LinkedIn and X.
  • After you approve:
    • You get an “Uploading…” message.
    • Upload-Post publishes:
      • To your LinkedIn organization page (configured by ID).
      • To X (Twitter).
      • To Threads.
    • The workflow sends a status message with success flags and URLs for each platform.

This is perfect for “talk to your phone, ship content to all your text platforms”.

How the Workflow Is Structured

  • Telegram Trigger
    Listens to every incoming message and routes by type:

    • /start → No-Op
    • voice → Audio pipeline
    • document/photo → Photo pipeline
    • video → Video/thumbnail/editor pipelines (/thumb, /edit or normal)

  • AI Blocks (Gemini + OpenAI)

    • Gemini 2.5 Flash for:
      • Photo understanding.
      • Short video descriptions (for auto-posting).
      • Long, detailed video summaries (for thumbnail generator).
    • OpenAI Whisper for voice transcription.
    • Multiple AI Agents (Gemini chat) with structured JSON output parsers for:
      • Per-platform social captions.
      • Threads/LinkedIn/X posts.
      • Thumbnail prompts and title concepts.
      • FFmpeg command generation.

  • Upload-Post Integration

    • Photos → Instagram, TikTok, Pinterest.
    • Videos → TikTok, Instagram, YouTube.
    • Text → LinkedIn page, X, Threads.
    • FFmpeg job endpoint for server-side video editing.
    • All uploads return status, URL and error messages back into Telegram.

  • Human-in-the-Loop

    • All critical AI outputs go through sendAndWait nodes in Telegram:
      • You review and choose whether to publish or not.
      • You choose which thumbnail concept to use.

Requirements & Setup

  • Accounts & APIs

    • Telegram bot (via @BotFather).
    • Upload-Post.com account with your social profiles connected.
    • OpenAI API key (Whisper).
    • Google Gemini API key (AI Studio).
    • Nano Banana Pro / fal.ai key (for thumbnails).

  • Runtime

    • n8n instance (cloud or self-hosted).
    • FFmpeg available where n8n runs (Docker image, VM, etc.) for local checks if needed (the heavy lifting is delegated to Upload-Post FFmpeg jobs).

  • Configuration

    • Create Telegram credentials with your bot token.
    • Create Upload-Post credentials with your API token.
    • Set upload_post_user and pinterest_board_id in the Edit Fields node.

Ideal Use Cases

  • Creators & influencers who want to post to every platform from one Telegram chat.

  • Solo devs & makers who publish workflows, devlogs and product updates and want:
    • Multi-platform video posts.
    • Voice → LinkedIn/X/Threads posts.
    • Easy text-based video editing and thumbnail generation.
