Unriddle AI

Unriddle AI is a research tool built around accurate citations. The reviewer says it gives precise citations backed by exact passages, handles complex multi-document analysis and supports up to 10,000 files in a single conversation. It also lets users search personal libraries and trusted sources such as PubMed and arXiv.

Unriddle AI starts at $10 per month, a price published by the vendor in September 2026. The reviewer notes that monthly plans come with limited credits, and upgrading for more usage costs extra.

Toolio lists Unriddle AI as best for researchers and scientists, especially those who need citation accuracy. It is not ideal for casual writers, and the reviewer finds it limited for general writing tasks. Alex gives it a Toolio score of 3.9 out of 5 after real use.

Yes. Unriddle AI runs on the web and as a desktop app for both Windows and Mac. On security, the vendor lists SOC 2 II and ISO 27001 certification and says the tool complies with GDPR and HIPAA standards.

The reviewer flags limited collaboration, with only 5 collaborators per folder unless a team pays more for the Pro plan. Unriddle AI also cannot extract text from images or scanned documents without additional software, so people who need image OCR should look elsewhere.
