Exa
Exa is a search API that gives AI agents real-time access to the web, built on its own large index, embedding and retrieval models, with selectable latency, search verticals, token-efficient highlights, structured enrichments and an MCP server.
- Built for agents, not repurposed consumer search
- Highlights cut downstream token cost
- Owns its index and retrieval models
- Latency and vertical control for real builds
- Not for end users wanting a search engine to read
- Benchmark and scale claims are vendor-stated
- People-search carries privacy responsibilities
Liner
Liner splits into three purpose-built agents: everyday search returning cited answers with one-click verification and mind maps, Liner Scholar for finding, comparing and citing papers and building literature reviews, and a writing agent that drafts, verifies and edits in the same window.
- Treats the citation as the output rather than a footnote
- Retrieval architecture makes fabricated references structurally impossible
- Three separate agents for three genuinely different jobs
- Verification inside the drafting window means checking actually happens
- Which indexes Scholar searches, and how completely, is not stated
- Case studies name users but quantify no outcomes
- Finding papers moves the bottleneck to reading them rather than removing it
