LegacyAI is an AI-powered tool designed to allow older Apple computers to interact with AI services like OpenAI's ChatGPT, providing you with a sophisticated and innovative personal assistant experience. It's the perfect solution for anyone seeking the capabilities of AI on their vintage Macintosh systems.


Here are just some of the features that LegacyAI offers:

  • Conversation Management: Save and load conversations for future reference
  • AI Model Customization: Change AI models to adapt to your needs

  • A Motorola 68020 CPU or better
  • At least 1.6MB RAM

Running Costs and Security

While LegacyAI is completely free to use, it is dependent on funding for API use and proxy server running costs. If you find LegacyAI useful and are in a position to donate, that would be greatly appreciated. It is important to note that because Mac OS 7/8/9 were built before HTTPS was a standard protocol for internet transmissions, any information you transfer is going to be insecure. Therefore, LegacyAI does not transmit information over HTTPS. Please bear this in mind and refrain from discussing sensitive subjects with the tool.

Download LegacyAI

You can download the LegacyAI software package directly from the Manticore Software website. The package includes versions compatible with Macintosh System 7 - Mac OS 8.6 as well as Mac OS 8.1 - Mac OS 9.2.2.
