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.

Branching AI canvas for ChatGPT, Claude and Gemini
Select any line of an AI answer to fork a new branch, so tangents stay explorable while the main thread keeps its shape.
Ask ChatGPT, Claude, Gemini, Grok and local models the same question side by side, and switch a chat's model in one click using your own API keys or subscription.
Wire PDFs, YouTube videos, web pages and notes directly into a chat so the model reads the full material rather than a search index.
Give it a goal and it plans the work, creates and connects nodes, hands pieces to subagents, then returns results to the canvas.
