Folio vs FrankenMarkdown

Folio keeps HTML files readable, interactive, and available offline—exactly the way they were made. No developer-operated server. No Folio account. No conversion that breaks the layout. Bring in a single HTML file or a folder-based page with its referenced CSS, JavaScript, images, and data. Folio gives each page its own local origin so modern pages—including ES modules, fetch requests, and local storage—can work the way they should. BUILD YOUR LIBRARY • Import files from Files or another app's Share sheet • Import a folder-based page with its referenced supporting files • Watch a folder for new and updated pages • Optionally add and refresh selected files from Google Drive • Organize with favorites, tags, searchable icons, sorting, grouping, and library search • Update many pages at once with bulk actions READ AND USE YOUR PAGES • Stay offline by default, with network access controlled separately for each page • Navigate page history, find text, reload, inspect source, and see useful diagnostics • Choose a top or bottom toolbar that gets out of the way as you read • Download files generated by a page, print, or save and share a PDF • Use a full three-column workspace on iPad or focus on the page full screen • Open chosen pages from widgets, and favorites or recent pages from Home Screen quick actions PRIVATE BY DESIGN • No Folio account, advertising, analytics, or tracking • Optional iCloud sync uses your private iCloud database • Optional Google Drive access is limited to files you choose for Folio • Lock individual pages with Face ID or your device passcode • Locked pages are shielded in the app switcher and badged in widgets and quick actions Two included interactive samples make it easy to explore Folio immediately. Keep reports, dashboards, exported notes, archived documentation, and other web files useful wherever you go—even when the network doesn't.

Write Markdown, inspect the document as a system, and publish a finished file without sending the text to a server. FrankenMarkdown keeps the source and rendered document together. The editor provides live syntax highlighting, line numbers, an outline, and an automatically updated preview. On iPad and Mac, source and output can remain visible side by side; iPhone uses focused lanes sized for the smaller display. Document Lab adds the tools needed for longer work: word and reading statistics, structure and accessibility checks, semantic comparison between revisions, polished document templates, and publishing controls. Multi-chapter projects can produce a continuous PDF or a self-contained site package. Export the current document as PDF or self-contained HTML. The bundled Rust rendering engine handles typography, tables, code, mathematical notation, and document structure locally. No account, advertising, tracking, or cloud processing is required. Your text stays on the device unless you choose to share an exported file.
