Exa
Exa is an AI search tool based on semantic search, using vector embedding technology to understand natural-language intent and return results that are semantically relevant even when they do not contain exact keyword matches. It is designed to serve AI applications that require meaning-based information retrieval rather than traditional keyword-based indexing.
Core Facts
Timeline (last 90 days)
A developer index focused on code, built by indexing GitHub issues, merged PRs, changelogs, and raw documentation, handles breaking changes in libraries better than general web search.
After the Exa search tool is integrated, it internally contains three tools: web search, webpage scraping, and Agent execution.
After the author connected the Exa web search MCP server to TrueForge, the agent produced a research summary via real web searches that included models such as DeepSeek R1, MiniMax, GLM, Mistral, and others.
Deep Dog 2's default configuration uses the DeepSeek V4 Flash model for the supervisor agent, research sub-agents, and the final drafting stage, with Exa used for retrieval.
Deep Dog 2 is compatible with both Exa and Tavily search engines.
Exa is a semantic search engine service provider for developers that uses embedding vectors for semantic indexing of the entire web, rather than traditional keyword inverted indexes.
Olostep's competitors include products such as Firecrawl, Jina Reader, and Exa.
Via the MCP protocol, local models can extend external capabilities, including a Hugging Face connector, GitHub query tools, Context 7 programming documentation queries, and Exa web search.
