Logically (formerly Afforai)

Logically, the product that used to be sold as Afforai, is an AI research assistant built around a personal library of documents. You add papers, PDFs, web pages and notes to a workspace, then query the whole collection in natural language. Answers are grounded in your own sources and surfaced alongside the passages they came from, so you can verify a claim before you use it instead of trusting a black-box summary.

The tool has grown into a wider writing and citation environment. Beyond chatting with files, it supports literature review workflows, PDF annotation, note-taking, outlines and drafting, with citation styles handled automatically. That makes it a good fit for students, academics and analysts who juggle dozens of references and need their writing to be traceable back to primary sources.

The Afforai brand was retired in favour of the Logically name, and the old domain now forwards to logically.app. Access to the service is subscription-based with a free tier that requires no credit card, and higher plans unlock unlimited storage and access to more advanced and reasoning AI models.
