About ChatGPTWizard

FusionAI (the evolution of the original ChatGPTWizard) is a free, open-source Delphi plug-in for Embarcadero RAD Studio that integrates AI-assisted workflows directly into the IDE. It supports multiple AI providers including OpenAI ChatGPT, Google Gemini, Anthropic Claude, and Ollama (offline). Users can ask free-form questions in a chat window, use inline editor prompts with cpt:...:cpt markers, and invoke predefined right-click actions such as explain, optimize, add comments, add tests, and find bugs. Additional features include a Class View for type-based prompts, provider-aware answer tabs for comparing responses, a searchable local SQLite history database with provider and model filtering, proxy configuration, file-based diagnostic logging, and configurable timeouts. The plugin targets RAD Studio versions 10.x (Berlin through Sydney) and 11.x (Alexandria); for older IDEs (XE2 to XE8), a separate branch is available.
