Absolute game changer for literature reviews and citations.
Tracing exact passages back to source papers is brilliant.
Best research tool out there.
Free tier limits are quite strict.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
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.
Draft in notes with citations suggested from your own library, then export to Word, LaTeX, or BibTeX in the citation style your journal requires.
Unriddle is best known as an AI research assistant for reading, organising, and writing scientific documents — and the product now lives on under the name Anara. Visiting the old unriddle.ai address brings you to the current Anara workspace, which keeps the same core proposition: keep a persistent library of your papers and data, search the academic literature, and write with claims that trace back to a source rather than to an unattributed model summary.
The workflow is built around a few concrete jobs. First, search: Anara queries over 300 million papers, supports filters for journal, year, and citation counts, and surfaces PubMed and clinical trial registry results, so you can screen candidates against your inclusion criteria and save the ones you need. Second, build: upload PDFs, notes, slides, and recordings (with OCR for scanned documents on the Pro plan) and the system keeps them indexed, with Zotero or Mendeley sync and metadata filled in automatically. Third, ask: query one paper, a folder, or your whole library, and receive answers that link to the exact passage — open-access full text where available — so verification takes one click.
Beyond answering questions, Anara handles the research busywork that general chat tools ignore. It can turn a folder into a cited extraction table with one row per paper and one column per question, exporting to CSV or Excel. It can draft in notes with citations suggested from your library and export to Word, LaTeX, or BibTeX in a chosen style. There is also an API and MCP server for programmatic search and citation resolution. Pricing runs from a free tier with limited usage to Pro at roughly $20 per seat per month (billed yearly), with Max and enterprise options above that. Full details are on the official pricing page.
Search literature across every field, filter by journal and year, and save the papers worth keeping into a library you can query later.
Generate reusable extraction tables with one row per paper and cited columns, then export to CSV or Excel for analysis.
Upload lengthy files, ask questions across all of them, and trace every claim to its source for submissions that must withstand review.
Draft sections in notes with citations suggested from your own library, then export to Word, LaTeX, or BibTeX in the required style.
