Overview

End-to-end automation from PDF upload to generated questions.

The AI agent ingests uploaded PDFs, converts them to plain text, and builds a structured knowledge graph of concepts and their relationships. It analyzes gaps between topic clusters to surface under-connected areas and missing connections. It then generates focused research questions and prompts that bridge those gaps and guide deeper inquiry.

Why you should use InfraNodus Research Question Generator

Before using this AI agent, you often rely on manual, time-consuming methods to find questions and gaps across PDFs. The response surface is limited by cognitive biases and fragmented notes. The process can take hours per project with uncertain payoff. You also struggle to connect ideas across disparate sources. Finally, you lack a repeatable way to generate prompts tied to observable gaps.

Before
Manual, time-consuming PDF review to identify potential questions.
Difficulty spotting gaps across multiple documents and topics.
Prompts often repeat common themes, missing novel angles.
Notes on connections are scattered and hard to trace.
No automated way to tie gaps to concrete research prompts.
After
Automatically surfaces cross-document gaps and key connections.
Generates clear, testable research questions for each gap.
Produces ready-to-use prompts for literature reviews or experiments.
Bridges topics across documents with new, data-driven connections.
Speeds up planning and reduces manual effort.
Process

How it works

Three-step system flow that converts PDFs into targeted questions.

Step 01

Upload PDFs

Users upload PDFs via the web form or an automated path, triggering the AI agent to begin processing.

Step 02

Extract and parse

The AI agent converts PDFs to plain text and prepares data for graph construction.

Step 03

GraphRAG analysis and prompt generation

The AI agent builds a knowledge graph, identifies structural gaps, and generates research questions and prompts.


Example

Example workflow

A realistic scenario showing time-to-value.

Scenario: A researcher uploads five PDFs (market reports and papers) totaling ~1,500 pages. In about 5–7 minutes, the AI agent returns 18 high-value research questions and 12 prompts ready to deploy in a literature review or an initial study.

FAQ

FAQ

Answers to common concerns about using this AI agent.

The AI agent accepts standard PDF documents. You upload files via the web form or connect via an automation path. PDFs are converted to plain text and then analyzed to build the knowledge graph. The results include generated questions and prompts aligned to the identified gaps.

No. This workflow uses InfraNodus GraphRAG APIs for knowledge graph generation and prompt creation, so OpenAI keys are not required. If you choose to hand off prompts to an external AI model, you can configure that integration separately. Data handling remains within the InfraNodus-enabled chain.

Yes. The AI agent is designed to route generated questions to external AI models or experts via your automation setup. This enables seamless handoff and collaboration without leaving your workflow.

The primary deployment uses InfraNodus GraphRAG APIs hosted by InfraNodus. Local or on-premise options depend on your InfraNodus plan. You can operate within your own secure environment if your deployment supports API access to InfraNodus.

Processing time depends on the number and size of PDFs. Uploads trigger parallel text extraction and graph construction, typically delivering results within minutes for moderate workloads. Large corpora may take longer, but the agent returns a structured set of questions and prompts as soon as gaps are identified.

Results are displayed in the AI agent interface and can be exported as prompts or integrated into downstream tasks via your automation platform. You can re-run the analysis with updated PDFs to refresh gaps and questions. The export format is designed to be immediately usable in research workflows.

Data privacy depends on your InfraNodus plan and your chosen deployment. The agent processes PDFs through InfraNodus GraphRAG and your automation connectors; ensure proper access controls and data governance. If handling highly sensitive materials, use on-premise or private-cloud options and limit access to trusted users.
