About Marplio
Marplio helps you write, preview, and export purpose-fit slides in the browser while keeping the source in Markdown.
Last updated: September 20, 2026What we are building
Slide work often mixes two different tasks: structuring the message and adjusting the visual design. Marplio separates them into writing in Markdown and choosing a reviewed design, so people without a design background can build readable presentations while staying focused on the content.
What you can use
Marplio brings template browsing, Markdown editing, Preview, verified expressions such as Charts and Mermaid, and PDF or PowerPoint export into one flow. You can try editing and standard exports without registering. A free account can save Decks so you can continue from the same Account Workspace.
Intended uses
Marplio is intended for proposals, plans, reports, technical talks, lessons, study groups, and portfolios whose content is revised over time. Always review the Preview and exported file, and retain your own copy of important Markdown and generated files.
Quality and supported scope
We test Preview, PDF, and PowerPoint output for consistent composition. PowerPoint, Keynote, and Google Slides can still measure fonts or reflow editable content differently. Help documents supported syntax, known limits, and diagnostic steps as the service evolves.
