Before you open the instrument
The evaluation instrument is a single HTML file that runs entirely in your browser. There is no server behind it and nothing you enter reaches this site.
Your keys
- You bring your own API keys for the providers you choose (Anthropic, OpenAI, Google Gemini, Perplexity). Requests go from your browser directly to that provider's API.
- The instrument saves its working state to your browser's local storage for this site, so a session can be restored. That saved state includes the keys you entered. They stay on your device; clear them with the instrument's reset or by clearing this site's data in your browser.
- Run records and exports are yours; nothing is uploaded anywhere.
What it loads
Three libraries from cdnjs for reading documents you attach as context (SheetJS 0.18.5, Mammoth 1.6.0, PDF.js 3.11.174). Nothing else.
The Keel v3 demonstrator
Keel runs in the browser, makes no network calls to model providers, and stores nothing. It loads React and Babel from unpkg and fonts from Google.
What it is
