The story behind the notepad, and the field tech who built it.

The maker

"At any moment I had 80 Notepad tabs open: credentials, subnet notes, procedures, the paste buffer of a whole workday. One reboot and it was all gone. So I built the notepad that never loses anything."

I'm Steve the Killer - a field technician and systems administrator at a large MSP, working in IT since 2017. I did not start there, though: I have been building websites since the 90s and spent roughly six years as a full-stack developer before I moved into IT, so building the tool I need comes as naturally to me as fixing the network in front of me.

A tech's day generates an absurd amount of loose text: passwords that should never sit in a plaintext file, IP schemes, one-off fixes you will absolutely need again in six months, and screenshots that belong next to the notes about them. The existing answers were either cloud notebooks that want an account and sync your credentials somewhere you can't see, or a folder of .txt files with no search and no pictures.

I wanted one fast local notepad that searches everything instantly, encrypts itself, and can tear off a sheet to hand a coworker. So I built it, and KillerNotes is the result.

The app

KillerNotes is a native Windows notes app built like an actual notepad: every note lives in one local database, saves itself continuously, and is full-text searchable as you type. No account, no cloud, no subscription.

It is built for a field tech's reality: paste a screenshot inline next to the note about it, drop real tables in for IP schemes, put a password on the whole database (SQLCipher AES-256) so credentials stop living in plaintext, and share a single note as a .knote file - or a whole database as a .kndb - with its own password when it needs one. All locally, with no telemetry and no ads.
