BillyGPT is a free, open-source, cross-platform desktop client for ChatGPT, designed for ease of use and enhanced chat management. It addresses limitations of the web interface by offering local chat history storage, automatic prompt optimization, and improved context memory, benefiting users who frequently interact with ChatGPT and require more control over their conversations and data.

How It Works

The client leverages Flet for its cross-platform UI, enabling deployment on Windows, Android, macOS, and web browsers. Its core innovation lies in a proprietary "chain-of-thought" prompt optimization technique that analyzes user queries to generate more detailed and structured responses, even from poorly phrased inputs. It also implements a summarization mechanism for long conversations to extend context memory beyond the standard web interface limitations.

Quick Start & Requirements

• Install dependencies via pip install -r requirements.txt.
• Run the application using python main.py.
• Requires Python. No specific version mentioned.

Highlighted Details

• Automatic prompt optimization using a "chain-of-thought" method.
• Enhanced context memory, approximately 1.5x that of the web version, via automatic summarization.
• Local storage and import/export of chat history, supporting breakpoint continuation.
• Ability to edit past chat messages and speaker identities.
• Support for custom API keys and font customization.

Maintenance & Community

The project is actively developed with a community support channel. Users are encouraged to join a technical development group or a user group for feedback and software source files.

Licensing & Compatibility

The project is open-source. The README includes a warning against uploading APIKEY.txt to GitHub due to exposure risks, suggesting careful management of API keys when forking or syncing the repository.

Limitations & Caveats

The project is still under development, with planned features including selective history inclusion, conversation summarization for titles, and keyword-based recall. Multi-instance parallel requests are noted as requiring an advanced API key.
