## What is Quantum Retriever?

Not all AIs work the same. With Quantum Retriever, you can search and compare their results. You can compare their answers, to see where they agree and where they don't. You can synthesize their results for more full answers. You can also evaluate specific models head to head, including many open source and experimental models. You can see how they rank on speed, token count, math and logic interpretation, and more. All your queries are only saved locally on your device, and are not shared with anyone outside this app.
