## Frequently asked questions

### Is my PDF uploaded to a server?

The file itself never leaves your device. Your browser extracts the text, and only that text is sent, encrypted end to end, to our server's AI model. The text is used to write the summary and is not stored or kept in logs.

### How accurate are the summaries?

Our AI model is told to report only what the document says, but AI can still miss a point or get a detail wrong. Use the summary to get the gist quickly, and check numbers, dates and anything important against the PDF.

### Which languages can the summary be in?

By default the summary uses the document's own language. You can also choose one of 40+ languages, including Hindi, Bengali, Tamil, Spanish, French, German, Arabic, Chinese, Japanese and Russian.

### Can it summarize a long PDF?

Yes. Long documents are read in parts and the notes on each part are combined into one summary. Very long PDFs are covered up to a few hundred pages; choose Pages to summarize a particular chapter or the rest.

### Why does it say my PDF has no text?

Scanned PDFs are pictures of text. Run the file through [OCR PDF](https://www.mergevanta.com/ocr-pdf) first to add a text layer, then summarize the new file.

### Can I summarize a password-protected PDF?

Yes. Enter the password when asked; it is only used in your browser tab to open the file and is never sent.

### Is the AI Summarizer free?

Yes — free, with no sign-up and no limit on the number of documents for normal use.
