You can get an AI document summary without an account, plus one complimentary AI answer per document set. The initial comparison uses that answer; a paid plan lets you continue with questions or suggested prompts. Starting a comparison counts as one daily task for the whole set. Uploading each file does not use a separate task. Free supports 15 MB combined; Professional supports 100 MB and Premium 250 MB. Your shared AI allowance also applies. ### How does Compare PDF work? Upload two or more documents within your plan's combined size limit, then click Compare. Files prepare in the background, and the document overview appears after you click. The AI compares content across the set, with filename and page citations for its findings. Ask about changed terms, prices, or other details, then check the cited passages in your PDFs. ### How many files can I compare at once? There is no file-count cap. You can compare more than ten PDFs within combined limits of 15 MB on Free, 100 MB on Professional, or 250 MB on Premium, and your remaining AI allowance. You need at least two distinct documents. Each file must also fit your plan's page limit: 50 pages on Free, 2,000 on Professional, or 3,000 on Premium. ### What is Compare PDF best for? Use it to compare vendor bids, review contract versions, or check figures across reports. A specific question such as 'How do the delivery dates and payment terms differ?' gives the comparison a clear focus. The cited output helps you organize your review; check the source documents before making a decision. ### What are the plan limits? There is no file-count cap. Combined set limits are 15 MB on Free, 100 MB on Professional, and 250 MB on Premium. Free includes an AI summary and one answer per document set, with a shared 15 MB daily AI allowance and a 50-page limit per document. Professional and Premium offer unlimited interactions within shared AI allowances of 2.5 GB and 5 GB per month, respectively. Their page limits are 2,000 and 3,000 per document. ### Does it show me a redline of what changed between two versions? Compare PDF returns a written analysis with source citations. It does not produce a tracked-changes PDF showing every insertion and deletion. Ask which payment terms, dates, or obligations changed, then open the cited pages to check both versions. Use a dedicated redline tool if you need every character-level edit marked. ### Can I compare two versions of the same contract? Yes. Upload both versions and ask about a specific clause, payment window, or obligation. Answers include filename and page references so you can check each version in the preview. The comparison focuses on content, which is useful when the drafts use different layouts. It is a review aid, not a substitute for legal advice. ### Can I export the comparison? Download the comparison conversation as a .txt transcript. When an AI answer contains a table, use its CSV button to export the rows and columns for Excel, Google Sheets, or another spreadsheet. Saving a multi-document conversation to your Library is not currently available in Compare PDF. ### Can it compare documents in different formats or layouts? Yes. Compare PDF focuses on document content, so reports or proposals can use different headings, columns, and layouts. Scanned PDFs are also supported through text recognition. The quality of the scan affects what can be read; check unclear figures and findings against the original page. ### Can I use this with the AI agents? Use Compare PDF to review documents together, then open a specific file with Proposal Analyzer, Resume Review, Assignment Review, or another specialist agent. The tools have separate conversations, and their processing draws from the same AI allowance on your plan. ### Can I open the source behind a comparison finding? Yes. Click a filename and page citation in the answer to open that PDF at the referenced page. When the source text can be matched, the relevant passage is highlighted. You can also preview any uploaded PDF and return to the document list with Back. --- Open this page in a browser: https://fynepdf.com/ai/compare-pdf More: [All tools](https://fynepdf.com/tools) · [AI agents](https://fynepdf.com/ai/agents) · [llms.txt](https://fynepdf.com/llms.txt) · [Sitemap](https://fynepdf.com/sitemap.xml)
