Lupad is a notepad whose tabs follow you between machines.
Plain text for Windows and Linux. Open it on either of your computers and the tabs you left are already there.
No account is needed to use it.
What it does
Tabs follow you
Sign in with Google or GitHub on each computer and the notes open on one are open on the other. Once you are signed in, notes are uploaded to the sync service; a note stops syncing when you save it to a file, and notes over the sync size limit are not synced.
Saved on this device
Notes are saved automatically on this device a moment after you type. No network is needed, and sync catches up later.
Plain text and nothing else
Tabs, find and replace, word wrap and zoom, in a Notepad-style layout with the usual shortcuts. No formatting, sidebars, toolbars or syntax coloring.
