Original n8n.io sourceThis powerful workflow can take hours of difficult research attempting to identify the perfect online tool to aid you with your business and condenses it into a few short seconds. Simply typing the name of an online tool you would like to identify into a chat message will initiate the workflow to begin its search process to identify 5 companies that will provide you with the online tool you desire. The initial chat will prompt the Tool Finder AI agent utilizing the power of GPT-4o in combination with SerpAPI to conduct a search and find 5 top end companies that contain the online tool you desire. It will then send the name of each company to five separate Reviewer Tool Agents that will gather information on each company. Each Reviewer Tools Agent will again harness the power of GPT-4o and SerpAPI to give a detailed descriptions of the online tool available including its price, limitations, summary of reviews, pros and cons, as well as an overall conclusion of the online tool.
This is the perfect workflow for anyone who is interested in obtaining an online tool to help automate business or everyday tasks. Rather than spending an excess amount of time searching through websites and review pages to determine the best product available this workflow completes the process for you. It provides five options in a condensed form that easily lets you compare and evaluate the options in a single place. Whether you are searching for an automatic email responder or the best available online spreadsheet, this workflow is exactly what you need to help bring your business to the next level.
Begin by opening the chat trigger node and typing the name of an online tool you would like to use to improve your day to day tasks. Example: Automatic email responder, automatic instagram poster, or online spreadsheet. This will trigger the Tool Finder Tools Agent to begin to utilize GPT-4o to begin to create search queries based off the tool you wish to identify. It will then use these search queries with SerpAPI to identify 5 companies that provide the online tool you desire. After it has obtained the names of five companies it will then in a structured output, send each item to a separate Reviewer Tools Agent. Once the Reviewer Tools Agent has received the name of the item it will then begin an in-depth review of that item. Each Reviewer Tools Agent will again use the power of GPT-4o connected with SerpAPI to obtain the most up to date information on each item from the internet. For each company and its tool you will be provided with:
After each of the Reviewer Tools Agent is complete with its review of the company and the online tool they provide, they will all send the information along to a Compiler Tools Agent. This tools agent uses GPT-4o-mini to arrange the data and present it in a concise, organized fashion. This allows for easy readability.

Use the JSON export at /data/workflows/6042/6042.json as the source template for this automation.
Open n8n, import the downloaded JSON, and review each node before activating the workflow.
Replace placeholder credentials, API keys, webhook URLs, account IDs, and environment-specific values with your own settings.
Run the workflow manually or in a staging workspace, inspect node output, and confirm downstream systems receive the expected data.
Enable the workflow only after testing, then monitor executions, errors, and rate limits during the first production runs.
Review imported nodes carefully before activation. This catalog entry is intended to help you inspect the workflow structure, understand required services, and find related templates faster.
Node names, credentials, schedules, webhook paths, and external service limits may need adjustment for your workspace.
