What is Quartzite?

Quartzite is an advanced chat interface that unifies access to multiple AI models, including Opus 4.5, Gemini 3, GPT‑5.1, and others. It provides an intuitive Markdown editor for crafting complex prompts, with a version history that tracks changes across model configurations.

A prompt optimizer applies best engineering practices automatically, while a template repository and variable support let users reuse and populate prompts quickly. The cost preview feature estimates token usage before execution, and data export options allow outputs to be downloaded in various formats.

Importing CSV data enables rapid creation of multiple prompt variations for data‑driven tasks. Developers, researchers, writers, and strategic planners can manage all models and prompts in a single app, improving productivity and reducing the need for separate platform logins.
