Decision-grade intelligence built on your own data
Connect internal systems, data rooms, databases, documents and live research, then normalize and govern access while preserving full lineage and auditability.
Encode AI steps, rules, tools, approvals and human review points into reusable workflows without writing code, while allowing engineers to extend them further.
Route each workflow step to the best-performing model or tool, optimize cost, speed and quality, and switch providers without lock-in.
Grade accuracy, relevance and output quality across workflows without relying on an engineering team, so quality stays measurable.
AI research platform for reading, understanding and writing scientific papers
Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.
