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 promptthumbnail (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 fullcommand. - 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.
