❖ What’s inside

Small on the surface. Thoughtful underneath.

Three quiet conveniences that shape how Zyler feels in daily use.

Privacy01

Private by default.

Every note lives on your machine as a plain file. Nothing syncs until you say so. No account, no cloud, no telemetry — the only thing leaving your laptop is coffee breath.

On-device AI02

A quieter spellcheck.

Llama 3.1-8B runs on your Mac — no API keys, no latency, no outbound packets. It catches typos, suggests a tighter sentence, and stays out of the way when you just want to write.

Structure03

Thoughts, rearranged.

Every block — headings, paragraphs, todos, quotes — is a first-class object you can grab and move. The outline of an idea shouldn’t be harder to edit than its words.

❖ Questions

A few honest answers.

In a folder on your disk. By default that’s ~/Documents/Zyler. They’re plain markdown with small .zysidecars for block metadata, so you can read them in any editor. If Zyler disappears tomorrow, your notes don’t.
Yes. Zyler ships with a quantized open-weights model (Llama 3.1-8B by default) that runs entirely through Metal on your Apple Silicon Mac. You can swap in any GGUF model you already have. The app makes zero outbound requests unless you explicitly turn on optional sync.
Not its own cloud — by design. Because notes are flat files, anything that syncs folders works: iCloud, Dropbox, Syncthing, Git. We’re building optional peer-to-peer sync for end-of-year.
It’s the same editing model you already know, applied to files instead of databases. No accounts, no server round-trip on every keystroke, no latency when the cafe wifi dies. Zyler is what happens when a block editor respects that writing is a private act.
Completely free. No subscription, no one-time purchase, no freemium ladder — the AI features are included by default.
