Stanislav Marynovych, Product/Project Manager and founder of the startup Just Solution, created an application called Kazhy (Say). The tool is designed for dictating text by voice on Mac computers and was created as a private and free alternative to popular paid services like Wispr Flow and Superwhisper.
According to Stanislav Marynovych , he has been practically not typing prompts, letters or large messages manually for a long time, using voice input. However, existing solutions have their drawbacks: they require a monthly subscription (about $15 per month), depend on the quality of the Internet connection and transfer user data to the cloud. In an effort to solve these three problems at once, the developer created his own utility for personal use, and now he has shared it with everyone for free and without any limits.
Kazhy is a native macOS application written in Swift (the author used Claude Code to develop the code), conveniently located in the system menu bar. All calculations and audio processing are done entirely locally on devices with Apple Silicon chips, and the network is required only once - for the initial loading of models.
The basis of the service is a combination of two AI models:
Whisper large-v3-turbo is responsible for fast and accurate speech recognition.
MamayLM (an optimized Gemma-3 4B model trained specifically for the Ukrainian language) performs high-quality text cleaning and formatting.
The application is designed with an emphasis on absolute privacy: audio recordings are not even saved to disk and are recognized directly in RAM. The mechanics of use are as simple as possible: just hold down the Fn key, dictate a thought and release it - and the finished text will immediately appear at the place where the cursor was. For long texts, a hands-free mode is provided.
Despite being free, Kazhy offers flexible settings to suit user needs:
Glossary: the ability to teach the service your own specific names, projects, or tools so that it recognizes them correctly, rather than literally by ear.
Levels of cleaning: from verbatim transcription to light removal of parasitic words or deep rewriting into structured text.
Tone settings: presets are available for standard, business style, note formats, or code comments.
Custom modes: the ability to create your own scenarios with specific prompts for specific tasks.
For comfortable operation of the tool, you need a computer based on Apple Silicon, at least 8 GB of RAM (16 GB recommended), and the latest version of macOS.
You can try out the tool and download it on the official project website: kazhy.marynovych.com .
