Machato is a native client dedicated to the macOS platform for managing the usage of OpenAI’s ChatGPT. It provides an interactive interface akin to regular instant messaging apps with additional powerful features tailored to make the most out of ChatGPT.

At its core, Machato offers granular control over the API parameters such as temperature, presence, and frequency penalty, top probability, and max tokens, allowing users to effectively tweak the response construction of the AI model.

It supports individual conversation management where users can create and manage distinct conversations each with its own history and configuration. Providing support for all chat OpenAI models available to the user’s API key, it allows for varied use-cases.

Key features also include code rendering with proper syntax highlighting, markdown support, LaTeX equation rendering, and token usage statistics for better resource management.

Machato includes a ‘Prompt Library’ to manage user prompts and system ‘personality’. It also enables an agile copy-to-clipboard function at the message level.

Future updates for Machato may include picture input support with the upcoming GPT-4, local LLMs support, and app localization. It is important to note that it is compatible with macOS versions 13.0 and above.
