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.
What it is
Instrument v3 as audited on 2026-09-01. The open defects are listed in the register; none of them affects your keys or your data.
