Installation
Every installer includes the Qwen3-0.6B local AI model and on-device speech recognition, so Reflex works offline as soon as it's installed. On first launch Reflex offers Qwen3-4B (about 2.5 GB, downloaded once) for smarter multi-step planning; you can also import the file if the computer has no internet.
macOS
- Download Reflex-…-mac-arm64.dmg (Apple Silicon: M1 and later) or Reflex-…-mac-x64.dmg (Intel).
- Open the DMG and drag Reflex to Applications.
- Open Reflex from Applications.
Current builds are not yet notarized by Apple. The first time you open Reflex, macOS may say it can't verify the developer. Open System Settings → Privacy & Security, scroll down, and click Open Anyway next to Reflex (you only do this once). If macOS says the app is “damaged”, run xattr -cr /Applications/Reflex.app in Terminal and open it again.
Requirements: macOS 12 or later, 8 GB RAM (16 GB recommended for Qwen3-4B), about 4 GB of disk space with both models.
Windows
- Reflex-…-win-x64.exe — standard installer (per-user, no admin rights needed).
- Reflex-…-win-x64.msi — for IT-managed installs.
Windows SmartScreen may warn about an unrecognized app while builds are unsigned: click More info → Run anyway. Requirements: Windows 10 (2004 or later) or 11, 64-bit, 8 GB RAM.
Linux
- Reflex-…-linux-x86_64.AppImage — runs on most distributions:
chmod +x Reflex-.AppImagethen run it. AppImages need FUSE 2: on Ubuntu 22.04+ install it withsudo apt install libfuse2(or run./Reflex-.AppImage --appimage-extract-and-run). - Reflex-…-linux-amd64.deb — Ubuntu, Debian:
sudo apt install ./Reflex-*.deb - Reflex-…-linux-x86_64.rpm — Fedora, RHEL:
sudo dnf install ./Reflex-*.rpm
For controlling other apps, Reflex uses the AT-SPI accessibility service: install python3-gi, gir1.2-atspi-2.0 (Debian/Ubuntu) or python3-gobject (Fedora) — the .deb and .rpm do this for you. For spoken replies install speech-dispatcher or espeak-ng.
Browser extension (recommended)
Reflex works in browsers through their accessibility interface out of the box. For precise, fast web automation in Chrome, Edge or Brave, add the Reflex extension and pair it: Settings → Browser extension → Pair, then enter the 6-digit code in the extension's popup. The extension only talks to the Reflex app on your own computer.
Updates
Reflex checks for updates from the official releases. Signed builds update themselves when you quit; unsigned builds tell you when a new version is available on this site.
Uninstall
- macOS: quit Reflex from the menu bar, drag it from Applications to the Trash. Your settings and skills are in
~/Library/Application Support/Reflex— delete that folder to remove everything. - Windows: Settings → Apps → Reflex → Uninstall. Data:
%APPDATA%\Reflex. - Linux: remove the package (
sudo apt remove reflex/sudo dnf remove reflex) or the AppImage. Data:~/.config/Reflex.
