Overview
What Unriddle is
Unriddle has become Anara, an AI research workspace that searches a user's library and scientific sources, answers with passage-level citations and supports source-grounded writing.
The current Anara product is built for scientific and evidence-heavy work rather than general note summarization. Users can import large document libraries, search databases such as PubMed and arXiv, ask questions across files, extract findings and draft with automatic citations back to the source material.
Use cases
Who Unriddle is best for
The strongest fit depends on the job you need the product to complete, not the size of its feature list.
Academic writing
Students and scholars drafting source-grounded notes and manuscripts with citation support.
Scientific teams
Groups working across large libraries, specialist databases and shared folders with stronger security requirements.
Capabilities
Core Unriddle features
Cited document answers
Links claims back to exact passages so the user can verify the model's interpretation.
Large research libraries
Supports conversations across many files and up to the plan-specific document and page limits.
Scientific source search
Connects to sources such as PubMed, arXiv, ClinicalTrials.gov and other research databases.
Write and cite
Helps draft text and suggests citations from the user's library and supported web sources.
Reference and cloud connectors
Paid plans expand integrations with Zotero, Mendeley, Drive, Notion, OneDrive and other systems.
Process
How the Unriddle workflow works
Step 1
Build a focused library
Import relevant papers and connect approved research sources instead of mixing unrelated documents.
Step 2
Ask comparative questions
Request evidence tables, differences in method or findings, and require links to the underlying passages.
Step 3
Verify before writing
Read the cited passages, check study quality and use the editor to draft only after confirming the evidence.

Assessment
Unriddle strengths and limitations
Where it stands out
- Every answer is designed to point back to source passages for verification.
- Scientific database and reference-manager integrations fit real research workflows.
- Handles much larger multi-document projects on higher plans than general chat uploads.
What to consider
- The Unriddle name and older product descriptions are outdated; the current service is Anara.
- Citations make checking easier but do not guarantee the model interpreted a paper correctly.
- Large-file, OCR, advanced model and deep-search capabilities require higher-priced plans.
