A fast, focused Markdown reader and editor for Windows.
Open a Markdown file, read it in a clean document view, edit the source, and see the result without leaving the window. Hashdraft works locally, starts quickly, and does not require an account, a browser, or any extra libraries.

Hashdraft keeps the source and the finished document close together. Switch modes at any time:
| Mode | Best for |
|---|---|
| Edit | Writing Markdown with syntax highlighting and formatting shortcuts |
| Preview | Distraction-free reading, printing, and checking the final layout |
| Split | Editing the source and watching the rendered document update beside it |
Scrolling stays synchronized in Split mode, so both sides remain at the same part of the document.

You can also select text in Preview and use the floating toolbar to apply common formatting without hunting for the matching source line.
Hashdraft renders Markdown as a native document rather than as a web page. It supports:
[[wiki links]]Preview includes zoom controls, full-screen reading, light and dark themes, and an optional table of contents that tracks the current section.
Open Settings from the gear button to choose:
PT Serif, PT Sans, and JetBrains Mono are included with the application, so documents look consistent without installing fonts separately.
Hashdraft does not require an account or a cloud service. Your documents are opened and saved locally.
To protect unfinished work, the application creates recovery snapshots for unsaved drafts and offers to restore them after an interrupted session. It also notices when another program changes an open file: clean documents reload automatically, while unsaved edits are protected from accidental overwrites.
Hashdraft-<version>-win64-setup.exe from the latest release..md, .markdown, or .txt file from Hashdraft. You can also choose Hashdraft from Open with in File Explorer.That is all. The installer already contains the required libraries, runtime files, plugins, and fonts. It installs for the current Windows user and does not require administrator rights or an internet connection.
Hashdraft registers itself as an available application for .md and .markdown files, but it does not change your Windows default application without permission. You can uninstall it from Settings → Apps → Installed apps.
Current unsigned builds may trigger a Windows SmartScreen “Unknown publisher” warning. This is a code-signing warning, not a missing dependency.
