Reviewer scorecard
“The API is exactly what AI agents need — semantic search that returns clean, structured content instead of HTML soup. Integrated it into our agent pipeline in an hour.”
“Vendor lock-in concerns. Hard to migrate once you're committed.”
“Better than Google Custom Search for AI use cases. The text extraction alone saves you from building a scraping pipeline. Pricing is reasonable for the value.”
“Exa is building the search layer for the agentic web. As AI agents need to research and gather information, Exa becomes essential infrastructure.”
“The API design is thoughtful. Integrates well with existing stacks.”
“Too expensive for what it offers. Plenty of open-source alternatives.”
