How the AI works

You bring the key. You see what is sent. You accept every change.

Quarivell has AI. Quarivell is not an AI tool.

Bring your own key

Use Anthropic, OpenAI, or Google — or a local model. You pay the provider directly. We never proxy your requests.

The send preview

Before anything leaves your machine, you see exactly what is sent — and what is held back.

Visible cost & provenance

Cost shows before you run. Grounded answers cite the source file and the page.

Local models

Keep everything on your machine when the work cannot leave it.

Getting a key, step by step

If you have never used an API key, this can read like a wall. It is three steps, and we walk you through each one.

  1. Step 1

    Create an account with a provider you trust.

  2. Step 2

    Copy the key they give you — once.

  3. Step 3

    Paste it into Quarivell. It stays on your machine.
