Chat with your papers, then search, extract and cite across your whole research library
Ask questions across a single paper or several documents and get answers grounded in the full text, with every claim linked to its source statement.
Search a large corpus of peer-reviewed literature in plain language and receive synthesized answers with citations rather than a raw list of links.
Import from Zotero or Mendeley or add papers by DOI, then annotate, store and reuse everything across search, review, extraction and writing.
Generate a structured, fully cited literature review from your own protocol, drawing on up to 50 papers at a time and organized by theme.

Enterprise-grade neural machine translation, AI writing refinement, and real-time voice translation across thirty-plus global languages.
Translates whole PDF, Word (.docx), PowerPoint (.pptx), Excel (.xlsx), and HTML files up to 30 MB (Individual/Team) or 100 MB (Business/Enterprise) while keeping original fonts, tables, slides, and visual formatting intact.
Ensures consistent brand and technical terminology across language pairs using CSV-importable shared glossaries, automated glossary generation, shared style rule lists, and translation memory.
Enhances original drafts and translated copy with real-time sentence rewrites, word alternatives, and one-click tone adjustments (e.g., Business, Academic, Casual, Diplomatic) via browser, desktop, and Microsoft 365/Google Workspace add-ins.
Provides real-time spoken language translation and live multilingual captions for video conferences and mobile in-person dialogues, with 30 minutes per user per month included in paid DeepL Pro plans.
