Try the Vectara Demo Agent

Use this guide to launch the Semiconductor Knowledge Assistant, a pre-configured agent that answers questions about semiconductors. Vectara creates the agent and its supporting corpus automatically, no manual configuration is needed.

By the end, you will be able to:

  • Launch the demo agent from the Console in a single click.
  • Chat with a working agent backed by real data. The demo uses Semiconductor data.
  • Understand the resources the demo creates so you can build on them.

Before you begin​

You need:

  • A Vectara trial or paid account (sign up free)
  • Permission to create agents and corpora in your account

Step 1: Access the demo agent​

You can start the demo from two places in the Console.

From the Welcome page (first time you log in with no agents yet):

  1. Sign in to the Vectara Console.
  2. On the Welcome to the Enterprise Agent Platform panel, click Try our demo agent.

From the Agents page (if you have no agents):

  1. Navigate to Agents in the sidebar.
  2. Click the Try out a demo agent option.

Vectara creates the following resources automatically:

  • A corpus named semiconductor-sample-data, pre-loaded with semiconductor documentation.
  • An agent named Semiconductor Knowledge Assistant (semiconductor_sample_agent), configured with recommended instructions and a corpus search tool pointed at that corpus.

When setup finishes, the agent is created and the Preview tab opens automatically.

Step 3: Chat with the agent​

  1. In the Preview tab, type a question in the chat input. You can also try the topics pre-loaded to get a headstart.
  2. Press the Enter key or click the Send button.

The agent searches the semiconductor corpus and generates a response grounded in that data.

Other questions to try:

  • "What is a MOSFET and how does it work?"
  • "How are semiconductors used in power electronics?"
  • "What is the difference between N-type and P-type semiconductors?"

Expected result: The agent returns a detailed answer with citations from the semiconductor corpus.

Verify the result​

A working demo agent shows:

  • Responses that reference semiconductor concepts from the pre-loaded data.
  • Source citations linked to the corpus content.
  • No fabricated or web-sourced answers (the agent uses corpus search only).

Troubleshooting​

What was created​

  • Corpus: semiconductor_sample_data — contains semiconductor documentation and is available for use in other agents.
  • Agent: semiconductor_sample_agent (Semiconductor Knowledge Assistant) — configured with recommended instructions and a corpora_search tool.

Both resources persist in your account. You can edit, delete, or reuse them at any time.
