Starts on a Telegram event

Quick overview This workflow receives startup ideas via a Telegram bot, uses OpenAI (GPT-4o and GPT-4o mini) plus Perplexity to score, research, and validate them, then generates a full business plan in Google Docs, logs key results to Google Sheets, and returns the plan link in Telegram. How it works Receives a Telegram message containing a raw startup idea. Uses OpenAI (GPT-4o mini) to structure the idea, detect its language, and assign an initial 1–10 idea score with improvement feedback. If the idea score is below the configured threshold, sends the score reasoning back to Telegram and stops. If the score meets the threshold, asks in Telegram for approval to run full research and plan generation. After approval, uses Perplexity to research the target market and competitors and then uses OpenAI (GPT-4o) to structure the findings, score market and competition, and generate differentiation and moat notes. Uses OpenAI (GPT-4o mini) to validate demand, risks, and go-to-market approach, then computes a composite score and recommendation.

Create AI product video ad Shorts from Telegram photos with OpenAI and AtlasCloud

Quick overview This workflow takes a product photo sent via Telegram, uses OpenAI Vision to describe it and OpenAI to write a short-form video ad prompt, generates a vertical video via AtlasCloud, then (after two approvals in Telegram) publishes the Short to YouTube via Blotato. How it works Triggers when a user sends a product photo (optionally with a caption/campaign) to a Telegram bot. Downloads the image from Telegram and uses OpenAI Vision to extract an advertising-focused product description. Uses OpenAI to generate a single cinematic text-to-video prompt plus a YouTube Shorts title and description. Sends the proposed prompt to Telegram and waits for your approval before proceeding. If approved, requests video generation from AtlasCloud and polls the render status until the video is completed. Sends the generated video back to Telegram for preview and waits for a second approval to publish. If approved, publishes the video to YouTube as an unlisted Short via Blotato and notifies you in Telegram (otherwise it stops and sends a decline message). Setup Create and connect a Telegram bot credential, then start a chat with the bot so it can receive photos and send approval prompts.

Force AI to use a specific output format

This workflow is for anyone looking to automatically fetch, validate, and parse complex language-based queries into a structured format. Its unique capability lies in not only processing language but also fixing invalid outputs before structuring them. Note that to use this template, you need to be on n8n version 1.19.4 or later.

Confirm and log WhatsApp restaurant orders with Groq and Google Sheets

Quick Overview This workflow triggers on incoming WhatsApp orders, uses Groq to extract items and quantities, validates them against a live Google Sheets menu, logs the result to an orders sheet, and replies to the customer with either a clarification request or a priced confirmation (with optional VIP owner alerts). How it works Triggers when a new WhatsApp message is received on your WhatsApp Business Cloud number. Sends the message text to Groq (Llama 3.3) to extract a structured list of ordered items and quantities. Reads the latest menu (item name, price, availability) from a Google Sheets “Menu” tab. Matches extracted items to the menu, checks availability, calculates line subtotals and the total price, and compiles any validation issues. If there are issues, replies to the customer on WhatsApp asking for a corrected order and appends a “needs_clarification” entry to the Google Sheets “Orders” tab. If the order is valid, appends a “confirmed” entry to the Google Sheets “Orders” tab and sends a WhatsApp confirmation with the item summary and total. If the confirmed total meets or exceeds the VIP threshold, sends a separate WhatsApp notification to the owner number. Setup Conne
