Syncphonia Light for the browser
A real local editor. No install.
Syncphonia Light is a free, lightweight Markdown reader and editor—not a demo and not the full desktop app. Open, read, edit, search, and export ordinary Markdown while your writing stays on this device.
Compare the free browser editor and desktop app.
A file or folder you grant stays in the location you chose. Where direct file access is unavailable, Syncphonia uses private storage on this device—not a Syncphonia server. Download Markdown copy exports an ordinary .md file whenever you want.
Three quiet steps
From download to document.
