*Create your Custom Business AI Agent that speaks, sees, listens and replies to your customers.* #### 🚀 What this workflow does 1. **Receives any inbound WhatsApp message** via a **PulpoChat Trigger** 2. **Detects the medium** – text, voice note, image or document (PDF) 3. **Processes accordingly** - **Text** → straight to the AI brain - **Voice notes** → download ➜ **Whisper** transcription - **Images** → download ➜ **GPT-4o Vision** analysis - **PDFs only** → download ➜ text extraction 4. Feeds the cleaned input + short-term **memory buffer (20 turns)** to an **OpenAI Chat Agent** (GPT-4o-mini by default) 5. Sends the answer back through PulpoChat: - **If the user sent audio, the bot replies in audio** (OpenAI TTS ➜ saves mp3 to Google Drive ➜ returns the public link). - Otherwise, returns plain text. 6. Gracefully rejects anything that isn’t text, image, audio or a PDF (“Sorry, you can only send …”) *Result:* a polite, context-aware concierge that can read your contract, describe your cat photo, or summarize a 3-minute rant into a single line—without ever leaving WhatsApp. #### 🧩 Key components | Node | Purpose | |------|---------| | **PulpoChat Trigger / PulpoChat** | Receive & send WhatsApp messages | | **Switch → “Input type”** | Routes to Text / Audio / Image / Document branches | | **HTTP Request** | Securely downloads media from PulpoChat | | **OpenAI Whisper** | Turns voice notes into text | | **GPT-4o Vision** | Describes images in detail | | **Extract From File** | Converts PDFs to text | | **LangChain Agent** | Central brain with custom system prompt | | **Memory Buffer Window** | Keeps the last 20 turns per chat | | **OpenAI TTS (“Generate Audio Response”)** | Converts answers to speech (voice “nova”) | | **Google Drive (Upload + Delete)** | Stores the mp3, grabs a share link, cleans up | (Sticky notes in the canvas label the four media lanes so future-you won’t get lost.) #### 🛠️ Prerequisites - **PulpoChat** device + API key - **OpenAI** API key (chat, whisper, TTS, vision) - **Google Drive** OAuth credentials (for audio replies) #### 💡 Ideas & extensions - Pipe extracted conversation data into HubSpot or Airtable. - Replace GPT-4o with your on-prem model ➜ just swap the Chat node. - Add a **Sentiment** node to auto-escalate angry customers. - Expand document branch to Word, PowerPoint or spreadsheets. #### ⚖️ Limits & best-practice nudges - Only PDFs are accepted for now; other file types trigger a polite rejection. - The workflow rate-limits itself by design (single execution per message), but you may want extra guards if you point it at a large audience. - Delete Google Drive files after sending (already included) to keep storage costs clean. - Remember WhatsApp’s 24-hour customer-initiated window. #### 🏁 Ready, set, automate! Import → Hit **Active**. Your WhatsApp number just became a futuristic, multimodal AI agent. Enjoy the peace and quiet while it handles the chatter. 😉
