AI reading and writing assistant that collects, curates, and creates content fast
Bring your feeds, links and reading sources together so new material arrives in one organized place instead of scattered tabs and bookmarks.
Let the assistant condense long articles and surface the parts worth keeping, so you can triage a big reading list in minutes.
Turn collected, distilled material into drafts, briefs and posts, keeping your output grounded in sources you already vetted.
Reading intake, curation and drafting live in one workspace, removing the copy-paste shuttle between a read-later app and a chatbot.

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.
