Frequently asked questions
Is Chat with PDF private?
The document and your question go directly from your browser to the Claude API over HTTPS — never to AirgapPDF servers, because there are none. Only Anthropic processes the file, under your own API account.
Do I need an API key?
Yes — bring your own Claude API key from the Anthropic Console. It is stored only in your browser’s local storage.
Is it free?
The tool itself is free and open source; you pay only Anthropic’s standard API usage for the tokens you use.
