aiPDF.ai

What is aiPDF.ai?

aiPDF.ai is an online AI tool designed for reading, summarizing, and answering questions about PDF documents. After uploading a document, users can pose questions, extract key information, and receive answers along with the locations of the relevant references in the document.

The platform is operated by British company LUMINATION AI LTD.; it supports single-document and multi-document conversations, as well as the ability to paste content URLs. It is useful for assisting with reading, but it cannot replace manual verification of contracts, papers, and professional documents.

Main functions

PDF Summary and Q&A

Users can ask the AI to summarize documents, explain terms, search for data, or organize sections. Answers are generated based on the uploaded content, which helps to save time spent on repeated searches within long reports and e-books.

References in the document

The official website states that the responses will include detailed citations from the original text, allowing users to return to the document for verification. The location of these citations can help with validation, but it is still necessary to ensure that the AI has understood the context, tables, and negative expressions correctly.

Multi-document dialogue

Multi Document Chat enables the use of multiple files within a single session, while Multi Document Joins is used to link different documents together. It is suitable for comparing versions of contracts, research papers, and multi-issue reports.

OCR text recognition

Different plans offer varying amounts of OCR capacity per page, and they can process scanned PDFs as well as image-based pages. Blurry, tilted, handwritten, or complex two-column pages may lead to recognition errors.

Import website content

The home page provides a field for pasting URLs, allowing supported web pages or online content to be imported for analysis. Pages that are subject to login requirements, anti-scraping measures, paywalls, or dynamic loading may not be able to be accessed successfully.

Document saving and management

Logged-in users can manage and upload content on the document page; different plans offer storage options of 1 month, 6 months, or unlimited duration. Users can also delete documents at will, but important documents should still be kept in their original form locally.

Which users are it suitable for

• Students and researchers who read papers, textbooks, and research materials
• Business users who analyze annual reports, industry reports, and market data
• Experts in comparing contract, policy, and regulatory documents
• Users who extract text and key information from scanned PDFs
• Knowledge workers who need to search through multiple documents and synthesize information.
• Ordinary readers who can quickly understand e-books, manuals, and long documents

AIPDF.ai Usage Guide

1. Register an account and select a plan based on the file size and OCR requirements.
2. Upload a PDF, or paste the URL of the public content you wish to analyze.
3. Wait for the system to parse text, tables, and scanned pages.
4. First, let the AI generate a structured summary to identify the document’s topic and sections.
5. Pose specific questions and require answers based solely on the current document.
6. Click or view the reference location to return to the original text and verify the key conclusions.
7. When comparing multiple files, give the documents clear names and define the scope of the issues.
8. After completion, export the required information and delete sensitive or no longer needed files.

Effective methods for asking questions

• Request that the key points and evidence be listed by chapter.
• Specify page numbers, time ranges, individuals, or metrics to avoid vague responses.
• It is required to distinguish between the facts in the original text, the author’s opinions, and AI-generated conclusions.
• When comparing documents, it is essential to identify the similarities and differences that need to be noted.
• When dealing with a contract, it is necessary to specify the obligations, deadlines, conditions for breach, and conditions for termination.
• When working on a paper, it is necessary to verify the research methods, sample, limitations, and conclusions.

Prices and packages

The prices listed below were verified on August 25, 2026, based on the official price page, which shows the average monthly cost under the annual billing option. Taxes, the total annual cost, and any promotions may change; the information on the settlement page shall prevail.

The Playful format documents are stored for 1 month, those in the Dynamic format are stored for 6 months, while there is no time limit for storing documents marked as Flagship. Enterprise offers commercial use and various other unlimited benefits; the details regarding data processing, support, and related terms need to be confirmed separately.

Multiple document limit

The “unlimited” option listed on the pricing page is still subject to fair use policies, technical capabilities, and service terms. Before carrying out frequent and large-scale usage, it is necessary to verify with the authorities the limits regarding speed, concurrent usage, and automation.

What is the free version suitable for?

The free plan allows for the uploading of two PDF files, the submission of 50 questions, and the processing of up to 50 pages of OCR text; it is suitable for testing the quality of text extraction as well as for occasional reading. The 35MB file limit may be insufficient for scanned books or reports that contain a large amount of images.

If long-term storage, comparison of multiple files, or scanning a large number of pages is required, Dynamic or Flagship should be considered. Before making an upgrade, test the table formatting, formula handling, and Chinese character recognition using representative files.

Document privacy and data processing

The official privacy policy states that the platform collects data related to accounts, usage, payments, and content submitted by users. The service makes use of the OpenAI API to process the content provided by users, and it relies on infrastructure such as Firebase Cloud Firestore.

The privacy page states that data may be processed in different countries, and the duration for which it is stored depends on the purpose of the service, as well as contractual and legal requirements. The official website also indicates that users can delete documents manually, but such deletion actions should be understood in the context of the account policies and those of third-party processors.

• Do not upload ID cards, medical records, unpublished financial statements, or customer confidential information.
• Before uploading contracts or research data, verify that the organization permits the use of third-party AI.
• Mask the data in the files by removing names, account numbers, and contact information.
• Delete the documents and shared links once they are no longer needed.
• Important summaries and citations are saved locally, while the original PDF is retained.
• Enterprises should sign appropriate data processing and confidentiality agreements prior to use.

Accuracy of answers and verification of references

AI may miss marginal notes, misinterpret tables, confuse different sections, or present assumptions as facts. The inclusion of citations does not guarantee the accuracy of the responses; it merely provides a basis for manual verification.

• Numbers, dates, and amounts must be matched item by item with the original text.
• Legal provisions should be read in their entirety and reviewed by professionals.
• When citing academic works, it is necessary to verify the author, year, page numbers, and the original paper.
• For scanned documents, first check the OCR text and then determine the results of the question-and-answer process.
• In multi-document conversations, it is necessary to ensure that the answers cite the correct version.
