Chat with PDFs
Upload a PDF and ask questions, get summaries, and find information through a chat interface designed for document Q&A.
PDF.ai
PDF.ai lets you chat with PDFs and process documents via API, with parsing, field extraction, and splitting for users and developers.
Overview
PDF.ai is a document AI product for chatting with PDFs and for processing them through an API. Its core workflow combines conversational Q&A with document parsing, field extraction, and PDF splitting so users can either review files interactively or build automated document workflows.
The site positions the product for both general users and developers. The web app lets people upload a document and start chatting, while the API Hub exposes endpoints for parsing, extracting, and splitting PDFs into structured outputs that can be used in applications and workflows.
Features
Parse documents
Parse documents into structured JSON with advanced OCR and layout detection, including headings, paragraphs, tables, figures, and page-level content.
Extract fields
Extract specific fields such as names, dates, amounts, invoices, and other custom data points using AI prompts.
Split documents
Split PDFs into sections, page ranges, or AI-defined chunks so documents can be separated automatically for downstream workflows.
Developer API
Use the API Hub endpoints and code examples to integrate PDF parsing, extraction, and chat into applications without needing an SDK.
Multiple ways to use the product
Start with the browser app, a Chrome extension, or API workflows depending on whether the task is interactive review or automation.
