TORONTO, CANADA ── INDEPENDENT ── BUILDING AI TOOLS THAT SHOULD ALREADY EXIST
══════════════════════════════════════════════════════════════════
THE STORY
One developer. One product. Almost ready.
Built on commutes. Built on AirPods. Built with the tool being built.
No team. No funding. No plan to stop.
This is what happens when someone decides to just build the thing.
THE PHILOSOPHY
Doing beats reading.
Shipping beats planning.
Local beats cloud.
Persistence beats performance.
The best AI developer tool is one that works while you walk to work — voice-first, always on, never forgets.
We build for builders. That filters most people.
WHAT WE BUILD
AI-native developer tools designed around how builders actually work. Voice-first. Local-first. Built on Apple Silicon. Tools that feel obvious the day after you start using them.

KLYSTRON
AI DEVELOPER OPERATING SYSTEM ── APPLE SILICON ── LOCAL-FIRST
══════════════════════════════════════════════════════════════════
"What if all your AI tools worked together as a team, instead of one at a time?"
THE PROBLEM
Most developers pay for 3–5 AI tools. None share memory.
Every session starts over. You rebuild context every time.
Tool sprawl. Keyboard friction. Compounding overhead.
THE SOLUTION
Klystron runs on your Mac and coordinates the tools you already use.
One persistent memory across all of them. Voice-first. No new API costs. No data leaving your machine. Ever.
THE FEELING
An AI that finally knows you. Every project, every decision, every line you have written — retrieved in the time it takes you to think.
Not a tab you switch to. A mind that runs alongside yours.

KLYSTRON TESTING CREW
Who we want: developers on Apple Silicon using 2+ AI tools daily.
You ship. You build. You have context-switching pain.
What you get: early access, direct line to the build, influence on what ships next.
Small group. High signal. No watchers.
INSIDE LIST
Not a developer? Not on Apple Silicon yet?
Join the inside list. Low volume — we only reach out when something real ships.
First access to new tools, products, and lab updates.
No noise. First mover access when it opens up.
