Extend Hard EA with desktop companion apps

Peek Viewer

A fast, lightweight image viewer with grid browsing, boss key (instant hide), and smooth folder navigation. Perfect for browsing your generated art collections.

RFab Companion App

The app that lets AI agents work on your computer — required for Vibe Coding and coding agents (they build, test, and run code through it). It also runs local AI models via Ollama, transcodes large video files for dubbing, scrapes inbox platforms, and bridges Live2D.

Getting set up

Run the downloaded file. Once it's running, the app lives in your system tray — the little icons near the clock at the bottom-right of your screen.
Our Windows apps are digitally signed, so you shouldn't see any security warning. In the rare case Windows still shows a blue "Windows protected your PC" screen (e.g. an old cached copy), click More info → Run anyway — or just re-download to get the signed version.
Go back to your agent. The site detects the running app automatically within about 30 seconds — no restart or pairing codes needed.
For coding agents: open the app from the tray, go to Settings → Security, and add the folder you want the agent to work in. Agents can only touch folders you've added there.
