Logically vs Paperpal

Logically is a research workspace for managing references, reviewing literature, annotating files, taking notes, and writing papers. Its AI assistant can search, summarize, and compare references across libraries, with inline citations and data sources. The reference manager accepts PDF, DOCX, TXT, MDOWN, EPUB, and PPTX files, along with URLs and DOIs. Users can import reference data from Zotero, Mendeley, and EndNote in RIS, BibTeX, or CFF formats. Semantic Scholar Mode draws on a database of 200 million peer-reviewed papers, and Logically says it supports more than 10,000 citation styles. Shared libraries, invitations, and collaborator permissions support group work. The free Cite Extension inserts citations and bibliographies from a Logically library into Microsoft Word; compatibility includes Word on the web, Word 2019 or later on Mac, and Word with Microsoft 365 on Mac or Windows. Logically runs as an extension, on macOS and Windows, and on the web. Free costs nothing and includes 100MB storage with daily AI-use limits. Unlimited is listed at $12 a year, billed at $12 per user/month yearly.

Paperpal is an AI research and academic writing workspace for students and researchers, combining writing help, citation tools, and academic checks. Users can upload references and PDFs, ask questions, and receive cited findings from more than 300 million verified research articles. Writing tools cover academic suggestions, paraphrasing, tone changes, word reduction, grammar, proofreading, and citation formatting. Its checker suite looks for plagiarism and AI-writing patterns, checks references, and assesses journal submission readiness. Paperpal runs on the web and as a browser extension; it also offers a Microsoft Word add-in and browser-extension support for Google Docs and Overleaf. The free plan includes 200 language suggestions, five generative AI uses per day, 7,000 plagiarism-check words per month, and five daily AI-detection scans of up to 1,200 words each. Prime costs $144 a year billed annually, or $25 a month billed monthly. Pro costs $348 a year billed annually, or $59 a month billed monthly. Paperpal says it does not train its AI models on user documents, uploads, or personal information, and allows document deletion.
