Legacy AI

LegacyAI is a client for ChatGPT (Generative Pre-training Transformer) created for older Mac OS systems, enabling users to communicate with OpenAI's ChatGPT from their computers.

It is an efficient tool for anyone using older Macintosh computers, acting as an AI personal assistant. Supporting Mac OS 9 through 10.6.8, the application allows users to select AI models based on their individual needs and configure proxy servers as required.

LegacyAI also allows users to save their conversations, switch between AI models to suit their needs, and completely adjust their preferences.

This tool can be used without charge, but continued API access relies on donations. Hosting the server and using the OpenAI API incur running expenses. If users are able to donate, they may do so through the provided link.

It requires a Macintosh computer running Mac OS 9 - 10.6.8, ideally with a G3 processor, a minimum of 16MB of RAM, and 1MB of disk space. Note that LegacyAI does not use HTTPS for information transmission, as Mac OS 9 predates HTTPS as a standard internet protocol.

While LegacyAI is free, transmissions made on an older Macintosh are not secure. Understanding this is essential; it should not be used for sensitive communications.

Manticore Software, a New Zealand software development agency founded by Jordan Trbuhovic, developed this tool.
