Reina, yourtrusty assistantwith a personality

Reina is a Windows assistant you can ask for help, or just talk to. Say “Hey Reina” and ask anything: Reina researches, runs your errands, comments on your games live, watches shows with you, and wanders your desktop in between.

  • No complicated setup
  • Gets cheaper as your hardware gets better
  • A persona you can rewrite

What Reina Does

All in one, and all one Reina

Six features, one personality. The same persona and the same voice drive all of it, so Reina never feels like a different person from one part to the next.

01

Talk out loud, or type

Say “Hey Reina” into your mic or type a sentence, then just talk. Small talk, hard questions, anything in between.

02

Live commentary

Turn commentary on and Reina watches your screens with you: reactions to the game or app in focus, company for whatever you are watching, all in the persona you chose.

03

Reina lives on your desktop

Reina perches on the top edge of any window, wanders over to visit your cursor, and wears an expression that matches what Reina just said. The sprite keeps to your main screen unless you let it roam. Drag Reina anywhere and that spot sticks.

04

Reina can use your PC

Ask Reina to open an app or click something and consider it done. Launching apps goes through Windows Search and never touches your mouse, so you can keep working. Harder tasks do borrow the mouse.

05

A voice that is free and offline

Speech is made on your own machine: no per-word cost, no trip to the cloud. Female and male voices ship built in, so Reina can talk the moment the install finishes.

06

Your settings stay yours

Settings, memory and learned answers live in your own app-data folder, outside the install. Updates cannot overwrite them, and uninstalling leaves them alone unless you say otherwise.

Moods

30+ moods, and more to come

A hand-drawn 2D sprite today. Live2D and 3D are on the way.

These are six of them. Reina picks the one that fits what was just said.

What It Looks Like

The app, with Reina in it

Dark by default, light if you prefer, or a gradient theme you build yourself. The conversation below is a real one. Nobody writes Reina's lines.

Persona

Rewrite Reina's persona

One setting changes how Reina talks and behaves, down to the little noises in between. A persona shifts what Reina feels and thinks, not just the choice of words. Pick from a curated list that keeps growing, or write your own in Persona Studio.

Running Cost

Reina gets cheaper with better hardware and longer use

Most of Reina's mind runs in the cloud today. Better hardware moves more of it onto your machine, and most of what anyone asks an assistant is the same handful of things, which the app answers locally instead of paying a model.

01

Common commands are instant and free

“What time is it”, volume and media keys, opening apps, quick math, coin flips, locking the PC: all answered on your machine, with no network call.

02

Reina learns what you repeat

Ask the same thing a few times and Reina starts answering from memory. Those answers expire after a few days so nothing goes stale, unless it is a memory worth keeping.

03

Reina goes quiet when nothing is happening

If the screen has not really changed (paused, on a menu, you stepped away), Reina skips that commentary call instead of paying to describe a still image. You still get a check-in now and then, to make sure you are alive.

Download

Get Reina

One installer. No complicated setup, no dependencies, no command line.

Operating system
Windows 10 or 11, 64-bit.
Processor
Any 64-bit CPU. Reina's hearing, voice and sense of when you have finished talking all run here, so more cores mean faster answers.
Graphics
None required. A strong NVIDIA card is the one upgrade that pays for itself: it lets Reina read your screen locally instead of paying for each look.
Disk space
About 1 GB free: around 340 MB to download, about 500 MB installed, plus roughly 140 MB of speech model fetched on first run.
Internet
Needed for Reina's replies and for reading your screen, which are both cloud calls. The voice and the desktop sprite stay on your machine, and hearing joins them once the speech model has downloaded.
Microphone
Any. Needed for the wake word, but you can always type instead.

Want to know when Reina releases?

Windows will warn you the first time. Reina has no code-signing certificate yet, because they cost real money for a one-person project. The warning means Windows does not recognize the publisher, not that it found something wrong with the file. Download Reina only from this site, then choose More info and Run anyway. Reina installs just for you and never asks for an administrator.

Reina is AI, and AI gets things wrong. Reina misreads a window, mishears a word, and will now and then say something wrong with complete confidence. Check anything that matters before you act on it, and especially before Reina acts on it for you.

Reina was also built with AI. One person and an AI assistant wrote Reina, which is how a program this size exists at all with nobody else on the payroll.
