    What is Cromagnon?

    Cromagnon is a collection of in-browser productivity workspaces and utility tools designed to handle sensitive documents and study materials. It provides full web-based editors for working with PDFs, spreadsheets, Word documents, slide decks, and data files without sending information across the internet. Instead of offloading processing to external servers, all conversions, edits, and calculations happen locally inside your web browser.

    The suite resolves the typical privacy and cost hurdles linked with subscription-heavy office software and online file converters. By processing documents entirely client-side, users avoid uploading confidential business contracts, financial logs, or personal study notes to third-party databases. It eliminates common pain points such as forced account creation, artificial queue timers, daily upload limits, and unwanted watermarks.

    What sets Cromagnon apart is its client-side processing architecture combined with offline installation capability. Because the tools run on your local hardware, you can complete document editing, text recognition, data reshaping, and flashcard practice without an active network connection, keeping sensitive records contained on your machine.

    Who is it for?

    Cromagnon is built for privacy-conscious users and learners who require full-featured file manipulation tools without monthly recurring fees.

    • Students who need to convert lecture notes into flashcards, generate academic bibliographies, and review mathematical proofs.
    • Office workers and business administrators editing contracts, managing spreadsheets, and redacting private PDF records.
    • Developers who want to format JSON, decode authentication tokens, and inspect regular expressions safely without network requests.
    • Educators looking to prepare worksheets, build presentation slide decks, and distribute study flashcards to their classes.
    • Content creators preparing web-ready graphics, generating vector QR codes, or converting image assets locally.

    Key features

    • In-Browser PDF Studio: Read, annotate, combine, split, sign, redact, compress, and password-protect PDF files, including optical character recognition to turn scans into searchable text.
    • FSRS Flashcard Study Studio: Review decks using the Free Spaced Repetition Scheduler memory model across eight study formats, turning slides, documents, or photos into flashcards across 107 languages.
    • Spreadsheet and CSV Tools: Edit Excel files with native formula execution, or restructure, filter, clean, and visualize large tabular datasets via the dedicated CSV studio.
    • Word and Document Processing: Write, format, and export authentic DOCX, HTML, and Markdown files with built-in autosaving directly inside your browser cache.
    • Multilingual Support: Full support for 107 languages, including native right-to-left layout rendering for Arabic, Hebrew, Urdu, and Persian scripts.
    • Academic Citation Studio: Compile reference bibliographies across styles such as APA, MLA, Chicago, Harvard, and IEEE, exporting to formats like BibTeX and RIS.
    • Step-by-Step Math Studio: Solve equations with step-by-step breakdowns, graphing output, and LaTeX export capabilities.
    • Offline App Installation: Install the entire suite onto your computer as an app to maintain access to file conversion, editing, and study features without internet connectivity.

    Pricing

    Cromagnon is completely free. The standard version costs $0 forever with no account required, providing full access to all 10 studios, over 76 utility tools, offline usage, and unlimited exports with no watermarks or limits. A free registered account is also $0 forever, adding 50 MB of encrypted cloud storage, device sync, and study deck sharing.

    Alternatives

    Cromagnon serves as a private, non-subscription alternative to document and study services. Compared to Quizlet, Cromagnon provides modern FSRS spaced repetition algorithms, document-to-card generation, and study tools completely free without paywalls or ads. Unlike Smallpdf or other online file converters that process your files on external web servers, Cromagnon executes all PDF editing and conversion tasks locally on your device for absolute data privacy.

    FAQ

    Is Cromagnon really free?

    Yes. All 10 studios and 76+ utility tools are completely free to use without daily caps, paywalls, or watermarks. An optional free account adds cloud storage and device sync at no cost.

    Do I need an account to use the tools?

    No. You can open any studio and work immediately without registering. An account is only needed if you want cross-device file synchronization or shared links.
