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.

Automate work across thousands of apps — no code required
Connect thousands of apps with a visual editor, using both point-and-click logic and natural language to define each step.
Connect AI tools such as Claude, ChatGPT and Cursor to your apps so they can read data and take real action.
Create AI assistants that answer questions and complete multi-step tasks across your connected systems.
Store structured data your workflows can read and update, keeping records in sync across tools.
