An AI memory layer that resurfaces your research when it matters
Capture web pages, PDFs, videos, reports and LLM chats while you browse, then annotate them with your own notes and context.
Instead of waiting for a search, Liminary surfaces the relevant saved material while you write and inside meetings.
A meeting companion that pulls in the right information at the right moment, then saves the summary, full transcript and your notes for later recall.
Every answer points back to where it came from, internal or external, so you can verify claims rather than trust a black box.
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.
