Ready-made database schemas, sample data and an AI schema designer
Browse ready-made schemas by subject, each with an ER diagram, full column details and an automated design review that calls out missing keys and indexes.
Describe the data you need in plain English, compare generated designs, and download generated rows with working foreign keys in CSV, JSON, SQL, Prisma or Django formats.
Write schema as DBML text and watch the diagram update live, then query generated rows in PostgreSQL or SQLite, inspect the query plan and share the whole thing as one reproducible link.
Deterministically generated datasets with valid foreign keys, available in eight download formats with no account, no attribution and no restrictions.
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.
