FAQ

Yes. Every feature on prisment.io — the editor, the viewers, presentation styles, local folder sync and HTML export — is free to use right now, with no account, no sign-up and no trial period, and the desktop app for macOS, Windows and Linux is a free download too. We are not charging for Prisment today; if that ever changes we will say so here first.

No. Prisment is completely client-side. All parsing and conversion are executed locally inside your web browser. Your private documents are never uploaded to any server.

Prisment is 100% client-side and serverless — your Markdown documents and user files are processed locally inside your web browser and are NEVER uploaded or stored on any server. On our hosted website (prisment.io), we use standard Google Analytics to measure aggregate page traffic and which features are used — for example that a desktop download or an HTML export happened, never the document itself — and to measure conversions for our own advertising campaigns. The desktop app collects only anonymous, aggregate usage data (a daily active signal, OS, app version, and country) to help us improve it, and you can turn it off anytime from the Help menu. On every platform, your document text, file names, and files are never collected or sent to analytics.

You can instantly drag, drop, or copy-paste Markdown (.md), MDX (.mdx), HTML (.html/.htm), CSV & TSV (.csv/.tsv), JSON (.json), and YAML (.yml/.yaml) files. Markdown is fully editable; JSON and YAML edit as syntax-coloured source; CSV opens as a sortable grid and HTML as a view-only preview. YAML OpenAPI/Swagger specs render as browsable API docs (any other YAML shows as code).

Yes! You can open, edit, and format MDX (.mdx) files in Prisment. Custom MDX React component rendering is not yet supported, but full custom component rendering is currently on our product roadmap.

Yes! You can drag and drop multiple Markdown files into a single multi-document workspace to manage, view, edit, and switch between files instantly.

Mostly. An exported page is a single HTML file that fetches its theme and runtime from cdn.prisment.io the first time it is opened, then caches them — so it opens anywhere with a connection, and offline from then on. On a machine that has never been online it falls back to showing your document as plain, copyable text instead of a blank page. For a copy that is guaranteed to work with no network, use Print / PDF.

You can copy the raw parsed HTML code to your clipboard, save the document as a print-optimized PDF, or download a fully responsive, standalone HTML web page.
