A free, AI-powered academic search engine for 240M+ papers across every scientific field
Search 241 million-plus publications from every scientific field using natural-language queries that match meaning rather than exact keywords.
Each indexed paper gets a one-sentence machine-generated TLDR so you can triage results before committing to reading the full text.
An augmented PDF reader that highlights citations, definitions, equations and figures inline, and shows which later papers cited the passage you are reading.
See how a paper was cited, whether citations were influential, and which references shaped the work — useful for literature reviews and citation chasing.
Agentic web scraper that turns any page into ready-to-use data
Open a page, click extract, and AI proposes the fields worth capturing and returns structured rows — no CSS selectors or drag-and-drop setup.
For popular sites like Amazon, eBay, and Google Maps, pre-built templates return consistent fields instantly without spending AI credits.
Thunderbit can open linked pages and pull details from them, so a results list and its detail pages become a single table in one run.
Summarize, categorize, translate, reformat, or calculate fields as part of the scrape, so exports arrive ready to use.
