Your data stays in your browser
- All scoring runs locally. No EFSI servers, analytics or tracking.
- A page is read only when you click Analyze.
- AI is off until you turn it on and add your own API key (Anthropic, OpenAI or an OpenAI-compatible endpoint).
- With AI on, only a trimmed excerpt (first 1,500 words), headings and an issue summary go to the provider you chose. Never raw HTML, links or images.
- Exclude any domain, and delete all data in one click.
What EFSI does not do
Scores are heuristic checks of observable page characteristics. They do not predict or guarantee rankings, or citations by any search engine or AI system. Analysis is English-first. Entity and E-E-A-T checks flag signals and do not verify truth or credentials. AI features use your own API key and may incur charges from your AI provider.
