LegacyAI allows older Apple computers to interact with AI services like OpenAI's ChatGPT.

LegacyAI works across 15 different Mac systems, from System 7 to 10.11 (El Capitan). LegacyAI has allowed Macintosh computers from 1988 and onwards to communicate with ChatGPT, even before iOS had an official app for it.

For a custom experience or non-ChatGPT usage, you can configure the application to use a proxy server or connect to a local or custom AI service.

Features:

• Converse with OpenAI's ChatGPT models on Mac OS 7 - 10.11 (El Capitan)

• DALL-E Image generation

• Save, load and view previous conversations

• HTTPS support

• Optionally use your own proxy server for further customisation, or to use LegacyAI with other AI platforms (Claude etc.)

• Customisable preferences

• Free to use but API access is dependent on donations

Minimum Requirements:

• A Macintosh computer running Mac OS 7 - 10.11 (El Capitan)

• A Motorola 68020, PowerPC, or Intel CPU

• At least 2MB Ram

• 2MB Disk Space

Notes:

Running costs
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, please do so here.

To unlock additional features and advanced AI models, you can purchase a license to help support the project.

If you'd like to support the project with a small monthly donation, you can sign up to a subscription.

Security
Any transmissions made on the 68k build are insecure due to System 7 - Mac OS 9 being released before HTTPS was an internet standard. Please ensure you understand this and do not use LegacyAI (68k) for sensitive subjects.

68k Users
LegacyAI also requires - MacinTalk 3 (specifically the "MacinTalk 3" extension and "Voices" folder within your system folder), and Open Transport to be installed.

Special Thanks
