Smart PDF Document Search & Reader

The full document is never uploaded. In-browser retrieval picks only the matched passages to send to the cloud AI (requires login and consumes AI credits) to synthesize the answer; the data is never used for model training. The local index lives on your device and is cleared when the page closes.

No. This is a cloud tool: answers are generated by our cloud AI and require a free account (signup includes trial AI credits); in-browser indexing and retrieval only pick the passages to send and do not produce answers on their own.

The engine extracts text page by page and builds a chunked index; at query time it retrieves the most relevant passages for the cloud AI to synthesize. Each answer item is annotated with its source page number, and clicking a citation jumps back to the original page for verification. Conclusions that cannot be drawn from the document are stated as such rather than invented.

It comfortably handles documents with hundreds of pages. Text chunking and indexing run locally and typically complete in a few seconds (depending on document size and device performance); only matched passages are sent per question and the cloud AI usually answers within seconds.

Never. Text chunking and indexing run entirely inside your browser's local memory and are cleared when the page is closed. Only matched passages are transmitted during AI synthesis queries, with zero use for model training.

Supported. However, since local retrieval relies on keyword matching, it is recommended to include original keywords from the document in your query to improve retrieval accuracy. Matched passages are then synthesized by the cloud AI into answers in your preferred language with page citations.

Yes. The cloud AI synthesizes from the matched passages and can summarize key points or organize figures into Markdown tables. Note that tables are reconstructed from plain text streams, so complex merged cells or intricate layouts cannot be perfectly replicated.
