How to Build an AI Assistant with Exa AI Real-Time Web Search

Imagine an AI assistant that doesn't just rely on outdated training data—but can search the web in real-time, find the latest news, research papers, product information, and more. With Exa AI, this isn't just possible—it's incredibly easy to implement.

🚀 What is Exa AI?

Exa AI is a next-generation search engine built specifically for the AI era. Unlike traditional search engines that return links, Exa provides semantic search capabilities designed for AI models to understand and retrieve relevant, high-quality web content in real-time.

With Exa, your AI assistant can access current news, research, product data, and any web content—transforming it from a static chatbot into an intelligent research assistant.

Step-by-Step: Enable Exa AI Search in Your Assistant

Let's create an AI assistant with Exa AI web search capabilities. This tutorial uses CalStudio's no-code platform—you can build this in minutes!

1 Create Your CalStudio Account

Start by signing up for a free account on CalStudio. Once logged in, click the "Create App" button to begin building your AI assistant.

2 Configure Basic Settings

In the "Basic" tab, set up your assistant's core configuration:

App Name: Choose a descriptive name (e.g., "Research Assistant", "News Analyzer")
Display Name: User-facing name shown in the chat interface
Description: Explain what your assistant does and its search capabilities
System Prompt: Define how your assistant should use web search (more on this below)
Model Selection: Choose your preferred AI model (GPT-4, Claude, Gemini, etc.)

3 Navigate to the Actions Tab

Click on the "Actions" tab at the top of the creation form. This is where you'll enable web search capabilities and configure your search provider.

⚠️ Important Note

Enabling web search adds 1 extra prompt per request. This is because the AI needs to first determine if a search is needed, then execute the search and process results. Factor this into your usage costs.

4 Enable Google Search & Select Exa

In the Tools section of the Actions tab, you'll see several available tools. Here's what to do:

Check the box next to "Enable Google Search"
A dropdown menu will appear labeled "Search Provider"
Select "Exa" from the dropdown (SerpAPI is the other option)
The system will automatically configure Exa AI as your search provider

🔧 What Happens Behind the Scenes?

When you enable Exa search, CalStudio automatically:

• Configures the Exa API integration with your app
• Grants your AI assistant access to real-time web search
• Optimizes prompt routing to determine when searches are needed
• Handles all API calls and response formatting automatically

5 Craft Your System Prompt

The system prompt is crucial for determining how your AI uses Exa search. Here's a template you can customize:

You are an intelligent research assistant with access to real-time web search via Exa AI.

Your capabilities:
- Search the web for current information, news, research, and data
- Analyze and synthesize information from multiple sources
- Provide citations and links to all sources used
- Distinguish between your knowledge and current web information

When to use web search:
1. User asks about current events, recent news, or time-sensitive information
2. User requests data, statistics, or facts you're uncertain about
3. User wants product reviews, comparisons, or market research
4. User needs academic papers, research, or technical documentation

How to use web search effectively:
- Always cite your sources with URLs when using searched information
- If search results are unclear, ask follow-up questions
- Combine multiple searches when needed for comprehensive answers
- Summarize findings clearly and acknowledge information gaps

Remember: Be transparent about when you're using web search versus your training data.

💡 Pro Tip: Customize for Your Use Case

Modify the system prompt based on your specific needs. For a news assistant, emphasize recency and fact-checking. For a research tool, focus on academic sources and citation quality. For product discovery, prioritize reviews and comparisons.

6 Configure Additional Tools (Optional)

Exa search works great on its own, but you can combine it with other CalStudio tools for powerful capabilities:

📅 Enable Date and Time Tool

Helps your assistant understand "today", "this week", etc. when searching for recent news and events.

🌐 Enable Web Fetching

Allows your assistant to fetch and analyze full webpage content from Exa search results.

🖼️ Enable Image Generation

Monetization options if you want to charge users

Best Practices for Exa AI Search Integration

🎯 Be Specific in Prompts

Train your assistant to ask clarifying questions before searching. Specific queries return better Exa results.

Example: Instead of "news about AI", use "recent AI breakthroughs in healthcare from the past month"

📚 Always Cite Sources

Configure your assistant to always provide URLs and source attribution when using Exa search results.

This builds user trust and allows them to verify information independently.

🔄 Combine Multiple Searches

For complex queries, instruct your assistant to perform multiple targeted searches and synthesize results.

Example: Search for "iPhone 15 reviews", then "iPhone 15 vs Samsung S24", then synthesize findings.

⚡ Optimize for Performance

Use the Date and Time tool to help your assistant understand temporal context and avoid unnecessary searches.

This reduces API calls and improves response times when handling time-sensitive queries.

🔍 Filter by Domain When Needed

For specialized use cases, instruct your assistant to focus on specific domains (e.g., .edu for academic, .gov for official data).

Example: "Search academic sources (edu domains) for climate research published after 2023"

⚠️ Handle Search Failures Gracefully

Train your assistant to acknowledge when searches return no results or encounter errors.

Instead of hallucinating, the assistant should say "I couldn't find recent information on that topic" and suggest alternatives.

Troubleshooting Common Issues

❌ "No search results found"

Cause: Query too specific or niche topic with limited web coverage

Solution: Broaden search terms, try alternative phrasings, or inform user that information may be limited

⚠️ "Assistant searches for every query"

Cause: System prompt doesn't clarify when to use internal knowledge vs web search

Solution: Update system prompt with clear guidelines: "Only search when information is time-sensitive or beyond your training data"

ℹ️ "Search results lack relevance"

Cause: Search queries too vague or poorly structured

Solution: Train assistant to formulate specific, targeted queries. Example: "latest iPhone models 2025" instead of "phones"

💜 "Want to switch between Exa and SerpAPI"

How To: Go to Actions tab, click the Search Provider dropdown, select your preferred provider

Note: Changes take effect immediately for new conversations

Understanding Search Costs & Limits

💰 Cost Considerations

When enabling Exa search, keep in mind:

• Each search query consumes 1 extra prompt in your usage quota
• Exa API has its own usage limits based on your Exa account tier
• Combining multiple tools (search + web fetch + image gen) increases per-request costs
• Consider implementing user rate limits for public-facing assistants

💡 Cost Optimization Tips

✅ Cache common search results in your system prompt or knowledge base
✅ Implement smart search triggers (only search when truly needed)
✅ Use conversation context to avoid redundant searches
✅ Set maximum search results limits in your prompts (e.g., "return top 5 results")
✅ Monitor analytics to identify and optimize high-cost usage patterns
