Outsmart Notes is a fast, private online notepad. Free is 5 saved notes, and you can try it with no signup for your first 15 minutes. Pro is unlimited notes for $5 per month or $49 per year and adds a vault, wiki links and backlinks, reminders and multi-device cloud sync. Notes are stored locally in IndexedDB, and it works as an offline PWA.
I built Outsmart Notes because I kept losing ideas to loading screens. It is plain JavaScript with no framework, it boots in under a second, and the Pro vault encrypts client-side with AES-GCM. Share links keep the key in the URL hash, so the server never sees your notes.
