Map the literature around the papers you love—free
Start from one paper and see how research connects through a visual map of related works, authors and citations.
The more you explore and select, the better it learns your interests, surfacing smarter and more relevant recommendations.
Explore how your existing review connects and discover papers you may have missed, avoiding endless flat article lists.
Bring your reference library and ResearchRabbit together so your collection and discovery work in one place.
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.
