Overview

End-to-end PDF querying with citations.

The AI agent ingests a PDF, extracts text and page metadata, and builds a searchable index of passages. It answers questions by querying that index and returning responses with precise citations to the source pages. It supports your preferred chat interface, allowing you to ask questions and share sourced answers across your workflow.

Process

How it works

A simple 3-step flow for non-tech users.

Step 01

Ingest PDF

Upload or point to a PDF; the AI agent parses the document and extracts text and page references.

Step 02

Index content and prepare citations

The AI agent creates a semantic index of passages and associates pages for citation.

Step 03

Answer with citations

The AI agent queries the index, generates concise answers, and returns citations pointing to exact pages.


Example

Example workflow

A realistic scenario showing a typical task and outcome.

Scenario: A 35-page product manual is uploaded. A user asks, “What are the installation prerequisites?” The AI agent responds with a concise list of prerequisites and cites the exact pages (e.g., pages 4–6) to support each item, all shown in the chat interface.

FAQ

FAQ

Practical questions about using the AI agent.

Yes. The AI agent can process several PDFs within a session by indexing each document and linking citations to their respective pages. It maintains context across questions by referencing the source passages and pages. For large sets of documents, you can batch uploads and query them separately or in combination, depending on your workflow. This keeps results relevant and auditable for each document.

The AI agent supports configurable LLMs, including OpenAI models or compatible self-hosted options. You can choose a model that balances latency, cost, and accuracy for your use case. The agent preserves citation integrity regardless of the model. If you switch models, existing citations remain linked to the original pages.

Citations are generated by linking answers to exact PDF pages and lines. They appear as inline references in the chat and can be extracted into reports. You can customize the citation format and the level of detail shown in responses. Citations are stored alongside the answer history for auditability.

Yes. The AI agent supports configurable citation styles to fit your documentation standards. You can select a style per project and adjust how page numbers and sections are presented. Changes apply to new answers and can be retroactively applied to exported results where supported. The system logs the chosen style for governance and compliance.

Processing can occur in the cloud or on-premises, depending on your deployment. For cloud setups, data is secured with industry-standard encryption in transit and at rest. On-premises deployments keep data entirely within your network. In all cases, citations remain linked to their source documents for traceability.

We support typical business PDFs; extremely large documents may require chunking to optimize indexing and query speed. If a file exceeds practical size limits, you can split it into smaller documents and index them separately. The AI agent maintains cross-document citation integrity when results span multiple files. For best performance, index only the needed sections or chapters.

Data security is prioritized with encryption, access controls, and audit trails. Citations are stored with their corresponding passages, ensuring traceability and accountability. Access to PDFs and results can be restricted by user roles, and activity logs support compliance reviews. You can also configure data retention policies to meet regulatory requirements.
