AI SQL assistant that writes, fixes and runs queries on your real schema
Describe the result you want in plain English or another language and get SQL written with your real table and column names in the dialect of your chosen database.
Paste any query — generated or hand-written — to get a clause-by-clause explanation, corrections with reasoning, performance rewrites and clean formatting.
Execute queries against a connected read-only connection and inspect the returned rows and timing directly in the interface.
Expose your database to Claude, ChatGPT in developer mode, Cursor or your own agent through a governed MCP endpoint and a REST API with per-agent keys.

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.
