Lune
The search engine built for scientific AI agents
Visit website →About
Lune is a search engine designed specifically to connect AI agents to trustworthy scientific literature. Instead of searching the open web full of low-quality content, Lune indexes full-text papers from top-tier academic conferences (A and A* rank only) — including equations and appendices.
Lune works as a plugin for ChatGPT and Claude via MCP, and also integrates with Cursor, Codex and 40+ AI apps. The core service is free with 10 requests per day, with paid plans starting at $4.99 per month.
It helps researchers through four stages: finding the research gap by tracking state-of-the-art work, designing experiments based on expected benchmarks and baselines, writing papers with verified citations, and peer review grounded in accepted practices.
Over 1,000 researchers already use it daily in their AI-native research workflows.

Why we picked it
General search engines give AI agents mixed-quality content. Lune restricts answers to verified scientific papers only. This matters especially in academic research where a wrong citation can ruin an entire paper.
