Logically

Logically is a web-based AI research workspace for students, researchers, and academics who need to find sources, manage citations, and write papers without juggling multiple apps.

Key capabilities include:

• AI research assistant that supports natural-language queries and searches across 200+ million academic papers (via Semantic Scholar), user-uploaded PDFs, and the web, returning citation-backed results.
• Reference manager for organizing sources across formats (including PDF, DOC, and EPUB) and generating citations in 10,000+ styles.
• PDF reading and annotation with highlighting and notes, plus AI help for explaining dense paragraphs and interpreting graphs.
• Literature review support, including source summarization, key-idea extraction, related-source discovery, and YouTube transcription that turns video content into queryable text.

Pricing: Unknown.

What makes it notable is the focus on end-to-end academic workflows (search, reading, annotation, reference management, and writing) inside one interface, with answers designed to stay grounded in verifiable citations rather than uncited summaries.
