MythDesk · Personal AI agent

Pull the plug. It still finishes.

MythDesk is a local-first personal AI agent for Windows. Myth works on your real PC: your apps, your files, your logged-in sessions. It runs in the background, asks before anything risky, and checkpoints every step so a crash or reboot never costs you progress.

Durable by default

Every step is a checkpoint.

Long tasks fail in boring ways: a crash, an update, a reboot, a laptop lid. Myth saves its state after every step, so when your PC comes back, it picks up exactly where it stopped. No repeated actions, no lost work.

Guardian

It asks before it acts.

A dedicated safety layer sits between Myth and your machine. You set the rules; risky actions stop and wait for you, on the desktop or on your phone. And the Stop button is always one click away.

Allow

Routine, reversible work you've cleared Myth to do on its own.

Reading files
Navigating apps
Drafting text

Ask

Anything with real-world consequences waits for your explicit approval.

Sending
Paying
Deleting
Logging in
Installing

Block

Things you never want an agent to touch. Myth won't, full stop.

Your own rules
Per app or action

Stop halts everything, instantly. A kill switch, not a suggestion.

Any model

Bring your own models. Or keep them local.

Myth isn't tied to one provider. Use your own API keys, or run entirely on your machine, and pick a different model for each role, so the expensive one only does the work that needs it.

Where it stands

NEXT MILESTONE

v0.1: “It never forgets”

MythDesk is pre-alpha. The first milestone is about durability: tasks that survive crashes and reboots, end to end.

In development

Desktop app for WindowsLocal-first

Can I use it today?

Not yet. MythDesk is pre-alpha and building toward v0.1. Join the waitlist to get early builds first.

What does it need access to?

Myth works on your actual Windows PC: your apps, files and logged-in sessions. That's what makes it useful, and why sending, paying, deleting, logging in and installing always require your approval.

Does my data go to JustMyth?

MythDesk is local-first: it runs on your PC. Model calls go to the provider you configure, or stay on your machine if you use a local model through Ollama, LM Studio or llama.cpp.

What happened to Mythdots?

MythDesk was previously called Mythdots. Same project, clearer name. The agent itself is still called Myth.

Is it open source?

No. MythDesk is proprietary, closed-source software.

Waitlist

Try MythDesk early.

Early builds go to waitlist members first. Expect rough edges, and a direct line to the person building it.
