About Qt AI Assistant
Qt AI Assistant is an extension for Qt Creator that adds an inline chat panel and context-aware code completion. It supports smart commands—/review, /qtest, /doc, /fix, /explain, and /inlinecomments—plus a QML linter that checks and amends generated snippets. You can route tasks to different LLMs (e.g., GPT-4o, Claude 3.7 Sonnet, Llama 3.3 70B, Codestral, DeepSeek V3) and run local models via Ollama, including Qt’s fine-tuned CodeLlama 7B/13B QML variants. Unit tests can be generated in Google Test (C++) or Qt Quick Test formats, and completions support partial acceptance (word or line). The plugin is available to selected commercial Qt developer licenses.
