❓ Frequently Asked Questions
Which AI model powers these PDF tools?
All AI tools are powered by Claude AI by Anthropic — one of the most capable and safety-focused AI models available. Claude is built by Anthropic and is known for nuanced text understanding, accurate summarization, and high-quality translation. No third-party AI services are used.
Is my PDF content sent to a server?
Only the extracted text is sent to the AI API — your original PDF file never leaves your browser. PDF text is extracted locally by PDF.js, then only the raw text is sent securely to Claude API for processing. The AI never receives or stores your PDF file itself.
Do I need an API key to use these AI tools?
No. The AI API key is handled entirely by PDF Online Editor — you never need to provide, purchase or manage your own API key. All AI tools work instantly without any setup, account creation or API configuration.
How accurate is the AI translation?
Very accurate for general, business and academic content. Claude AI handles technical terminology, formal language and complex sentence structures well. For RTL languages like Urdu and Arabic, the tool also applies proper right-to-left text layout and script rendering. For legal or medical documents, always review with a professional translator.
What types of PDFs work best with AI tools?
Digital text-based PDFs work best — documents created from Word, exported from software, or PDFs with selectable text. For scanned or image-based PDFs, use the OCR PDF tool first to make the text extractable, then use any AI tool on the result.
Is there a page limit for AI processing?
Most AI tools work on PDFs up to 100 pages. Very long documents (200+ pages) are automatically chunked — the AI processes each chunk and combines the results. For the best summary quality on very long reports, consider splitting the PDF by chapters first using the Split PDF tool.
Can I use AI tools on confidential documents?
Exercise caution with highly sensitive documents — while only the text is sent (not the file), it does pass through an external AI API. For documents classified as top secret or legally privileged, consider redacting sensitive sections first using the Redact PDF tool before AI processing.
