A smart personal assistant that can reason, search, calculate, and remember โ€” powered by Google Gemini and ready in one click.

Most AI agents only respond โ€” this one thinks before replying, pulls in real-time facts, does the math, and even remembers the last 5 things you said.

๐Ÿ”ง How it works This template builds a conversational agent using the Google Gemini API. It uses multiple tools like:

๐Ÿง  Think โ€“ to reason step-by-step ๐Ÿ” SerpAPI โ€“ to search live data on Google โž— Calculator โ€“ to solve math problems ๐Ÿ’พ Memory โ€“ to remember short-term chat history

You can embed this agent into a chatbot, web app, or automate any customer support, research, or productivity workflow.

๐Ÿง  Your agent will:

  • Understand what you're asking
  • Think logically using the Think tool
  • Search facts in real-time using SerpAPI
  • Calculate numbers using a math engine
  • Recall past context using a memory buffer
  • And respond clearly โ€” just like a real assistant.

๐Ÿง‘โ€๐Ÿ’ผ Who is this template for? This template is ideal for:

  • Creators & developers building AI agents
  • Teams needing a Gemini-powered assistant
  • Beginners exploring LangChain + n8n
  • Anyone curious about combining LLMs + tools + memory

๐Ÿš€ How to set up

  1. Plug in your Google Gemini API key
  2. Add your SerpAPI key
