Cromagnon
Free browser studios for PDFs, Word, Excel and flashcards
About Cromagnon
Cromagnon is a set of browser-based workspaces for people who handle everyday files and coursework. It offers ten studios covering PDFs, Word documents, Excel spreadsheets, CSV data, slides, images, citations, maths, invoices and flashcard study, plus more than 70 quick tools for developers and text work.
Files are processed on the user's device rather than uploaded, so sensitive documents such as contracts or payslips stay local. No account is required, the site states there are no watermarks, and installed studios keep working offline. Sync between devices is optional.
The Study Studio is positioned as a free alternative to Quizlet and Anki, using the FSRS memory model and turning PDFs, slides or photos of notes into flashcards in 107 languages. PDF Studio covers editing, signing, redaction, OCR, merging and compression. Students, teachers, office workers, developers and online sellers are the intended audiences, and work can be exported to common formats like PDF, DOCX, XLSX and PPTX.
