Source-grounded autocomplete

Suggests the next sentences as you write and can be limited to the papers in your own library. Free accounts get 10 suggestions a day.

Traceable citations

Links each AI-suggested sentence to the page and paragraph of the source PDF, and formats references in more than 10,000 styles, including APA 7th, Chicago and IEEE.

Library and paper search

Holds uploaded PDFs and collections imported from Zotero or Mendeley, and searches an index of more than 200 million papers from inside the editor.

AI Chat across the library

Answers questions about one paper or the whole library with cited replies, which can be filtered by publication year, impact factor and citation count.

Reviews

Checks each claim in a draft against its sources and flags problems such as unsupported or overstated claims, alongside proofreading suggestions.

Collaboration and export

Co-authors edit in real time with inline comments, viewer and commenter roles and version history. Documents export to .docx, LaTeX or HTML.

Trinka

Grammar and style checks

Checks grammar, technical spelling, tone and sentence structure for formal writing. Paid plans add Power mode and corrections that follow the APA, AMA, ACS, AGU and IEEE style guides.

Plagiarism and AI detection

Plagiarism reports cost 24 credits (standard) or 36 credits (advanced), and the AI detector 1 credit per 5,000 words. Premium Plus includes 240 pages a year of standard checks.

Citation tools and Journal Finder

A citation checker flags retracted and unverifiable references, a formatter applies major citation styles, and Journal Finder suggests journals for a manuscript.
