What our users say about Quartzite
"Using the API-powered Quartzite, my API usage is much lower than the monthly cost of the flagship AI products. Quartzite basically paid for itself already in the first month. The extra prompting tools that Quartzite provides on top of this huge benefit is the icing on the cake."

FAQs
What is the “Lifetime Deal”?
We're offering the opportunity to purchase Quartzite AI at a significant discount while it's still in development. Your purchase will support the ongoing development efforts of our independent team. In return, you'll get lifetime access to the full app and all future updates. See the Terms & Conditions for more details.
What's an "API key"? Do I need one?
An API key is a code (similar to a password) that allows you to interact with some AI models. For example, with the OpenAI API key, you can interact with GPT-4 in other apps, such as Quartzite. With an API key, you pay only for your usage of the AI, rather than paying for a subscription. Doing this usually results in lower costs compared to paying for tools such as ChatGPT Plus (we personally spend less than $2-3/month for our usage). If all of this is new to you, don't worry - we have some guides on how to get the API key, and we'll be happy to support you if you need assistance.
How is my data handled?
Quartzite AI communicates directly with OpenAI, and your data is stored locally in your browser, ensuring your privacy (even we don't have access to it).
How is this different from ChatGPT and OpenAI playground?
First of all, Quartzite AI gives you access to other 3rd-party models, some of which have large free tiers (e.g. Google's Gemini PRO). Additionally, Quartzite AI offers a range of features not available in ChatGPT, including templates, version comparison, markdown editor, variables, and more. We believe these significantly enhance productivity and output quality.
How does the 14-day money back guarantee work?
If you're not satisfied with the app, you have 14 days to request a full refund. No questions asked, and we'll return your money immediately.
