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.
The relevance engine with a built-in feedback loop
Retrieve, filter, score, and re-rank across semantic search, keyword search, and behavioral models in a single SQL-like query.
Blends semantic and keyword retrieval, then re-ranks results by predicted click-through and engagement for each individual user.
ML models retrain on live interaction signals so ranking quality improves automatically as your product generates traffic.
Stream data directly from warehouses, analytics tools, and event pipelines like Snowflake, Kafka, BigQuery, and Shopify with no ETL.
