Document Lab – AI PDF Reader, Summarizer, Writer & Document Tools

Key Features & Benefits

Chat with Any PDF

Upload any PDF document and ask questions about its content. The AI reads and understands the entire document, providing accurate answers based on what is actually written in the file.

Page References

Every answer includes references to the specific page or section where the information was found. This makes it easy to verify the AI's responses and navigate directly to the source material in your document.

Client-Side PDF Extraction

Your PDF is processed entirely in your browser using client-side technology. The raw file is never uploaded to any server — only the extracted text is sent to the AI for analysis, ensuring your document privacy.

Multi-Turn Conversations

Ask follow-up questions to dive deeper into specific topics. The AI maintains context from previous questions, allowing you to explore a document progressively without repeating yourself each time.

Key Topic Extraction

Automatically identify the main topics and themes discussed in your document. This gives you a quick overview of what the document covers before you start asking specific questions.

Large Document Support

Handle PDFs up to 50 pages with reliable text extraction. Longer documents are processed in chunks to ensure the AI can provide accurate answers even for lengthy reports and research papers.

Document Outline

Get an instant overview of your document's structure with key sections and page ranges. This helps you quickly locate the information you need without scrolling through the entire file.

Copy & Export Answers

Copy any AI response to your clipboard with a single click for use in your notes, reports, or presentations. Each answer preserves its formatting and page references for easy reference.

AI PDF Reader – Frequently Asked Questions

How does the AI PDF Reader work?

Upload a PDF file and the tool extracts the text content using client-side PDF processing. The extracted text is then sent to an AI model that can answer your questions about the document. The AI provides answers with page references so you can verify the source.

Is my PDF file uploaded to a server?

No. The PDF file is processed entirely in your browser using client-side JavaScript. Only the extracted text is sent to the AI for analysis. Your original PDF file never leaves your device, ensuring complete document privacy.

What types of PDFs are supported?

The PDF Reader supports text-based PDFs including reports, research papers, contracts, manuals, and articles. Scanned PDFs (images of text) may not work well because the tool extracts text, not images. For scanned documents, use the OCR tool in Visual Lab first.

How many questions can I ask about one document?

You can ask as many questions as you like about a single document during one session. Each question counts as one use of the tool. The AI maintains context from previous questions in the conversation for more coherent follow-up answers.

Can the AI read tables and charts in PDFs?

The AI can read text that is extracted from PDFs, including text within tables. However, visual charts and graphs that are rendered as images cannot be read by the text extraction engine. For image-based content, use the OCR tool instead.

What is the maximum PDF size I can upload?

The tool works best with PDFs up to 50 pages and 10MB in size. Larger documents may take longer to process and could be truncated to fit within AI token limits. For very large documents, consider splitting them into smaller sections.

Are the AI's answers always accurate?

The AI provides answers based on the document content, but like any AI system, it can occasionally misinterpret context or miss nuances. Always verify important answers against the original document, especially for legal, medical, or financial content.

Is the PDF Reader free to use?

Yes, the PDF Reader is free during the beta period with daily usage limits. Each question you ask counts as one use. No credit card is required. You need a free account to use this tool.

Key Features & Benefits

Five Summary Modes

Choose from Brief (concise overview), Detailed (comprehensive analysis), Bullet Points (scannable list), Executive Summary (decision-maker format), or Key Takeaways (most important points) to get exactly the type of summary you need for your workflow.

Key Points Extraction

Automatically identifies and extracts the most important points from your document. Each key point is presented as a clear, standalone insight that captures the essential information without requiring you to read the full text.

Action Items Detection

Finds and lists any action items, tasks, deadlines, or next steps mentioned in the document. This is especially valuable for meeting notes, project proposals, and business communications where follow-up actions are critical.

Reading Time Estimate

Shows the estimated reading time for both the original document and the summary, so you can quickly gauge how much time you are saving. This helps you decide whether to read the full document or rely on the summary.

Word Count Comparison

Compare the original word count with the summary word count to see how much the content has been condensed. This helps you understand the compression ratio and whether you need a more detailed or briefer summary.

PDF or Text Input

Upload a PDF file or paste text directly — whichever is more convenient. The tool handles both input methods seamlessly, extracting content from PDFs client-side for privacy or accepting pasted text for quick summarization.

Context-Preserving AI

The AI preserves the original meaning and key information while condensing the text. It avoids introducing new information or changing the intent, ensuring the summary is faithful to the source document.

Instant Copy & Export

Copy the entire summary, key points, or action items to your clipboard with one click. Use the results in your notes, emails, reports, or presentations without manual transcription.

Document Summarizer – Frequently Asked Questions

What summary modes are available?

There are five modes: Brief gives a short paragraph overview, Detailed provides a comprehensive analysis, Bullet Points creates a scannable list, Executive Summary formats for decision-makers, and Key Takeaways extracts the most important points. Choose the mode that best fits your needs.

Can I summarize PDFs directly?

Yes, you can upload a PDF file and the tool will extract the text content automatically using client-side processing. Your PDF file is never uploaded to any server — only the extracted text is sent to the AI for summarization.

How accurate are the summaries?

The AI generates summaries that preserve the key information and meaning of the original document. However, summarization inherently involves some loss of detail. For critical documents, always review the summary against the original to ensure no important points were missed.

What types of documents work best?

The summarizer works well with reports, articles, research papers, meeting notes, contracts, proposals, and any structured text document. Very short texts (under 100 words) may not benefit much from summarization, while very long documents may be truncated to fit within AI token limits.

How long can the input text be?

The tool handles documents up to approximately 50,000 characters. Longer documents are truncated to fit within AI processing limits. For very long documents, consider summarizing section by section for more detailed and accurate results.

What are action items?

Action items are tasks, deadlines, follow-ups, or next steps mentioned in the document. The AI automatically identifies these and lists them separately, which is especially useful for meeting notes, project proposals, and business communications.

Can I summarize in different languages?

The summarizer primarily works with English text. For documents in other languages, the AI may still produce a summary but the quality could vary. For best results, use English documents or translate the text first.

Is the Document Summarizer free?

Yes, the Document Summarizer is free during the beta period with daily usage limits. Each summarization request counts as one use. No credit card is required, but you need a free account to use this tool.

AI-Powered Quality

The AI generates coherent, well-structured content that follows professional writing standards. It creates documents that are ready for review and minor editing, saving hours of drafting time compared to starting from a blank page.

Document Writer – Frequently Asked Questions

What types of documents can I generate?

You can generate seven types: Business Reports (data-driven analysis), Cover Letters (job applications), Contracts (basic legal agreements), Proposals (project or business proposals), Memos (internal communications), Articles (informative content), and Blog Posts (engaging web content). Each type follows standard formatting conventions.

Can I edit the generated document?

Absolutely. The AI generates a first draft that you can copy, download, and edit in any word processor. We recommend reviewing and customizing the output to add your personal touch, specific details, and any information the AI could not have known.

Are generated contracts legally binding?

No. Generated contracts are templates and starting points only. They are not reviewed by lawyers and may not comply with your jurisdiction's legal requirements. Always have a qualified attorney review any legal document before signing or using it.

How do I choose the right tone?

Professional tone works for most business documents. Formal is best for official or legal communications. Casual suits internal team messages and blogs. Academic is ideal for research papers and scholarly writing. Persuasive works well for proposals and sales documents.

What does Short, Medium, and Long mean?

Short produces approximately 1-2 pages of content (300-600 words), Medium produces 3-5 pages (800-1500 words), and Long produces 5+ pages (1500+ words). The AI adjusts detail depth to match the selected length while maintaining quality.

Can I generate documents in other languages?

Currently, the Document Writer generates content primarily in English. If you specify in your prompt that you want the document in another language, the AI may attempt it, but quality may vary. Full multilingual support is planned for a future update.

Is the generated content unique?

Yes, the AI generates original content based on your prompt each time. While it draws on patterns and conventions for each document type, the specific wording, arguments, and details are generated fresh. However, always review for accuracy and add your unique perspective.

Is the Document Writer free?

Yes, the Document Writer is free during the beta period with daily usage limits. Each document generation counts as one use. No credit card is required, but you need a free account to use this tool.

Key Features & Benefits

PDF Converter – Frequently Asked Questions

Is my PDF uploaded to any server?

No. All PDF processing happens entirely in your browser using client-side JavaScript. Your files never leave your device. This ensures complete privacy and security, especially for sensitive documents like contracts or financial records.

Do I need an account to use the PDF Converter?

No. The PDF Converter runs entirely in your browser with no server-side processing required. You can use it without creating an account, and there are no daily usage limits or restrictions.

What PDF operations are supported?

The tool supports four operations: Merge (combine multiple PDFs into one), Split (extract specific pages from a PDF), Compress (reduce file size), and Reorder Pages (change the page sequence). More operations are planned for future updates.

How does PDF compression work?

The compression tool optimizes the internal structure of the PDF, removes redundant data, and reduces image quality where possible while maintaining readability. The compression level is balanced to produce significant size reduction without making the document unreadable.

Can I convert Word documents to PDF?

Direct Word-to-PDF conversion requires server-side processing which is not available in the current client-side implementation. For now, you can open your Word document in any browser and use Print to PDF, then use our tool for further PDF operations.

Is there a file size limit?

Since processing happens in your browser, very large PDFs (over 100MB) may cause performance issues depending on your device. For best results, work with files under 50MB. The merge feature supports combining multiple files as long as your browser can handle the total size.

Does the tool work on mobile devices?

Yes, the PDF Converter works in modern mobile browsers. However, for complex operations like merging many files or reordering pages, a desktop browser provides a more comfortable experience with a larger screen and easier file management.

Is the PDF Converter really free?

Yes, 100% free with no hidden costs, no watermarks, and no file limits. Because the tool runs entirely in your browser, there are no server costs to pass on. Use it as much as you need, anytime, for free.

Key Features & Benefits

Grammar & Spelling Check

Detect and highlight grammar errors, spelling mistakes, and punctuation issues in your document. Each issue comes with a clear explanation and suggested correction, helping you improve your writing quality and avoid embarrassing mistakes.

Tone Analysis

Analyze the overall tone of your document and get feedback on how your writing sounds to readers. The AI identifies whether your tone is professional, casual, formal, aggressive, or passive-aggressive, and suggests adjustments to match your intended communication style.

Readability Scoring

Get a readability score that indicates how easy or difficult your document is to read. The tool uses standard readability metrics and provides a grade level equivalent, helping you adjust complexity for your target audience whether they are general readers or subject experts.

Legal Clause Detection

Identify potential legal clauses, obligations, liabilities, and risk-related language in your documents. This is especially valuable for reviewing contracts, terms of service, and business agreements to flag areas that may need legal review before signing.

Style Consistency Check

Check your document for consistent writing style throughout. The AI identifies shifts in tone, voice, or formality level that may confuse readers, and suggests adjustments to maintain a unified style from beginning to end.

Overall Quality Score

Receive an overall quality score from 0 to 100 that summarizes the document's quality across all checked dimensions. This gives you a quick snapshot of how much work the document needs and helps you prioritize which areas to improve first.

PDF or Text Input

Upload a PDF file or paste text directly — whichever is more convenient. PDF text extraction happens client-side for privacy, with only the extracted text sent to the AI for analysis. Your original files never leave your browser.

Selective Checking

Choose exactly which checks to run: Grammar, Tone, Readability, Legal, or Style. Run all five for a comprehensive analysis, or focus on specific areas to get targeted feedback without waiting for unnecessary checks.

Document Checker – Frequently Asked Questions

What does the Document Checker analyze?

The checker analyzes five dimensions: Grammar (spelling, punctuation, and grammatical errors), Tone (the overall voice and how it sounds to readers), Readability (how easy the text is to understand), Legal (potential legal clauses and risk language), and Style (consistency of writing throughout the document). You can select which checks to run.

How accurate is the grammar check?

The AI grammar check detects a wide range of common errors including subject-verb agreement, tense consistency, punctuation issues, and commonly confused words. It is comparable to premium grammar tools for most standard writing, but may occasionally miss nuanced or context-dependent errors. Always review suggestions critically.

What is the readability score based on?

The readability score considers sentence length, word complexity, paragraph structure, and overall text difficulty. It provides a grade-level equivalent (e.g., College, High School) so you can gauge whether your document is appropriately complex for your intended audience.

Is the legal check a substitute for a lawyer?

Absolutely not. The legal clause detection is an AI-based tool that identifies language commonly associated with legal obligations, liabilities, and risks. It is designed to help you spot areas that may need professional legal review. It does not provide legal advice and should never replace consultation with a qualified attorney.

Can I check documents in languages other than English?

Currently, the Document Checker is optimized for English text. It may produce results for other languages, but the accuracy and relevance of the analysis will be significantly lower. Full multilingual support is planned for a future update.

What does tone analysis tell me?

Tone analysis identifies the overall voice of your document and how it is likely perceived by readers. It can tell you if your writing sounds professional, casual, formal, assertive, or tentative. It also suggests adjustments if your tone does not match your intended communication style.

How is the overall score calculated?

The overall score is an average of the individual scores from each check type you selected (Grammar, Tone, Readability, Legal, Style). Each dimension is scored from 0 to 100. A higher score means better quality. Scores below 60 typically indicate significant room for improvement.

Is the Document Checker free?

Yes, the Document Checker is free during the beta period with daily usage limits. Each check request counts as one use regardless of how many check types you select. No credit card is required, but you need a free account to use this tool.
