Izuki: The Free, Open-Source AI Companion for Windows

Izuki is a free artificial intelligence assistant built specifically for Windows 10 and Windows 11. Created by Solomon Nwachukwu, an IT and cybersecurity student, this tool acts as a digital sidekick that lives on your screen. It listens to your voice, understands what you are doing on your computer, and helps you complete tasks using your mouse and keyboard. Unlike other chatbots that just talk, Izuki can see your screen and interact with your applications directly. It is completely free to use forever and runs on your own hardware to protect your privacy.

Benefits

Izuki offers several powerful advantages for anyone looking to make their computer more efficient. First, it provides natural voice interaction. You can wake it up by saying "Hey Nova" or use a special keyboard shortcut. It uses lifelike voices that pause at the right moments and supports many languages including Nigerian English and Swahili. You can also control your PC from your phone using a web browser or apps on Telegram and Discord.

The tool excels at understanding your screen. It can read hidden buttons and fields to answer questions like where a specific export button is located. It uses a safety system called Safe Hands to verify clicks before acting, which prevents mistakes if your screen layout changes. You can even draw on your screen with your mouse to circle an element and ask Izuki for help explaining it.

Productivity is another major strength. Izuki can handle complex multi-step tasks like downloading files, opening apps, and filling out forms all by itself. It can read and write files in formats like Word and PDF, run terminal commands, and even summarize your Gmail inbox. For students, it has a special Teacher Mode that explains quiz questions and points to the correct answer without clicking it for you, helping you learn while you study.

Safety and privacy are built into the core of the software. Izuki will never type into a password box or read a password field. It cannot act on the Windows lock screen. It avoids pressing high-risk buttons like Submit, Send, or Delete unless you give very specific instructions. All wake-word detection and speech-to-text happen locally on your PC. Screenshots are only sent to the AI provider you choose, such as Google Gemini or Groq, and nowhere else. The code is open source, meaning anyone can review it for transparency.

Use Cases

Izuki is designed for a wide range of everyday situations. Students can use it as a study buddy. The Teacher Mode can pause videos, quiz you on the material, and explain difficult concepts step by step with on-screen drawings. It can also set reminders for homework deadlines and notify you on both your PC and phone.

Professionals can use it to speed up their workflow. It can automate repetitive tasks like opening specific applications, scrolling through long documents, or managing files in your system. It can connect to Gmail to find important attachments and summarize long email threads so you can focus on what matters. Developers can use it to run terminal commands or explain code by drawing on the screen.

The tool also works with smart TVs. It can control Roku, Samsung, LG, Android TV, and Fire TV devices. You can use your voice to search for content or control playback, and the AI orb can display on your TV screen for a hands-free experience.

Pricing

Izuki is entirely free forever. There are no hidden costs or subscription fees. Users only need to provide a free API key from a service like Google Gemini, Groq, or OpenRouter during the initial setup. This key allows the AI to process requests, but the software itself costs nothing to download or use.

Vibes

As a new open-source project, Izuki has generated excitement in the tech community for prioritizing user control and privacy. The creator, Solomon Nwachukwu, built it as a proof of concept for accessible AI assistants. Early feedback highlights the impressive ability of the tool to interact with the Windows operating system in ways that standard chatbots cannot. Users appreciate the safety guardrails that prevent accidental clicks and the flexibility of the voice options. The fact that it runs locally on your hardware and does not require a paid subscription makes it a popular choice for those who want powerful AI without giving up their data.

Additional Information

Izuki is built using Rust and Tauri, which makes it fast and efficient. The source code is available on GitHub under an MIT license, allowing anyone to view, modify, or distribute the software. The mobile companion apps for Android and iOS are also free. While the main version currently supports Windows 10 and 11, versions for macOS and Linux are in development. The project represents a growing movement toward personal AI tools that respect user privacy and remain open to the community.
