What is Logically?

Logically (formerly Afforai) is a SaaS platform that merges research, reference management and writing into one AI-assisted workspace. You upload PDFs, EPUBs, DOCX files, URLs, DOIs and more into an organized library of folders and tags, then chat with your documents, search across a database of 200M+ peer-reviewed papers (plus Google and Semantic Scholar modes), and write with AI that suggests the next sentence while attaching a real citation to back it up. It generates bibliographies in 10,000+ citation styles, annotates PDFs with highlights, sticky notes and AI explanations, and includes shared libraries and Word/Chrome extensions. It's aimed at students, researchers, consultants, lawyers and content writers who want to skip juggling Zotero, ChatGPT, Google Docs and Acrobat. Its biggest strength is convenience — everything in one subscription — but it ships with usage caps on advanced AI models and a daily credit system that has already eroded buyer trust. The Unlimited lifetime deal was $79 on AppSumo and is currently sold out.
