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.
An AI research workspace where every answer points to the exact passage it came from
Search more than 300 million papers across medicine, physics, and other fields, filter by journal, year, or citation count, and save relevant results to your library with one click.
Upload papers, notes, slides, and recordings; Anara indexes them all and lets you ask questions scoped to a single file, a folder, or your entire collection.
Every answer points to the exact passage it came from, verifiable in one click — the core differentiator versus general chat assistants.
Turn a folder of papers into a structured table with one row per paper and one column per question, with every cell cited, then export to CSV or Excel.
