LegacyAI is a software developed by Manticore Software that allows older Macintosh computers to communicate with AI services like OpenAI’s ChatGPT. It can be used in 15 different Mac systems, ranging from System 7 to 10.11 (El Capitan). LegacyAI can be configured to fully customize the user’s experience, using a proxy server to do so. Its main features include conversing with OpenAI’s ChatGPT, image generation with DALL-E, the ability to save and load conversations for future reference, customization of AI models, and customizable preferences.$#$#LegacyAI is free to use, but its API access is dependent on donations to cover running costs. Those who find LegacyAI useful and are in a position to donate are encouraged to do so. For additional features and AI models, a license can be purchased to support the project. Users can also sign up for a small monthly subscription to support the project.$#$#It is important to note that LegacyAI does not transmit information over HTTPS. As Mac OS 7/8/9 was built before HTTPS became a standard protocol for transferring information over the internet, any transmissions made on an older Macintosh are insecure. Therefore, users are advised not to use LegacyAI for sensitive subjects.$#$#LegacyAI is available for download in three versions: LegacyAI (68k) 2.4.0 (Macintosh System 7 - Mac OS 8.6), LegacyAI (PPC) 2.4.0 (Mac OS 8.1 - Mac OS 9), and LegacyAI (Universal Binary) 2.4.0 (Mac OS X - Mac OS X 10.11 El Capitan).$#$#Manticore Software is a New Zealand-based agency founded and run by Jordan Trbuhovic.
