Multi-Modal AI Memory Assistant: GPT-4o, MongoDB & Gmail

This n8n workflow builds a powerful multi-modal AI Memory Assistant that ingests voice notes, images, PDFs, and text messages via Telegram. It leverages GPT-4o for advanced processing: Whisper transcribes audio, Vision analyzes images, and robust parsing handles documents, converting all inputs into unified textual representations.

Next, it intelligently chunks content, generates embeddings, and stores them in MongoDB Atlas Vector Search for semantic retrieval. The assistant enables lightning-fast recall of personal or business information, acting as an external brain for knowledge management.

Gmail integration allows the AI to search, send, and manage emails within responses. Benefits include seamless multi-format capture, AI-powered understanding, persistent memory, and automation of recall tasks. Ideal for personal productivity, fitness tracking (voice-logging workouts, image-based progress scans), business notes, or any scenario needing intelligent info retrieval.
