Frequently Asked Questions

What is semantic search?

Semantic search understands the meaning and context behind your questions. Instead of just matching keywords, it finds passages in your PDFs that are conceptually related, giving you more relevant results.

Is my data secure and private?

Yes, absolutely. The entire process—from reading your PDFs to running the AI model—happens locally in your web browser. Your files and search queries never leave your computer.

Why is the first search on new documents slower?

The first time you search a document, the tool creates numerical representations (embeddings) of its content. This can take a moment. These embeddings are then cached in your browser, making all future searches on that document much faster.
