Rather than exporting text and losing the document's structure, it translates the file as a document: tables, images and diagrams keep their original positions, so academic papers, reports and manuals remain readable and do not need to be rebuilt by hand. This is the feature the product leads with, and it is the main reason teams use it instead of a generic text translator. The service is designed for heavy documents. Pro Premium and Business plans translate files up to 1,000 pages and 200 MB in one pass, while the entry Pro Standard plan covers up to 100 pages and 50 MB. Translations are unlimited on a flat monthly fee and finished files can be downloaded as often as needed. A glossary function lets you pin down how product names, abbreviations and research terminology are rendered, which keeps wording consistent when several people review the same set of documents. Online files can also be translated through a Chrome extension. Readable supports more than 200 source languages into Japanese, with the Pro Standard plan focused on English-to-Japanese and Pro Premium opening up the full language range. You can choose between the service's own engine and a ChatGPT-based translation engine depending on the document, and the site notes that a separate paid DeepL subscription is not required. Plans start at 800 yen per month, a 7-day free trial is offered, and a Business/Kakenhi option with quotes and invoicing is available for organisations — security reviews and supporting documentation are handled as a separate paid service. **Pricing & Plans:** Pro Standard is 800 yen per month (English-to-Japanese, up to 100 pages/50 MB per file) and Pro Premium is 4,000 yen per month (200+ languages, up to 1,000 pages/200 MB), both unlimited in translation count. A Business/Kakenhi plan is quoted on request for teams and invoicing needs, and there is a 7-day free trial limited to one use per person or company. - **Layout-preserving translation:** Tables, figures and diagrams stay where they were, so context and data structure survive translation and you can share the result as-is. - **Large-file capacity:** Pro Premium and Business plans accept a single file of up to 1,000 pages and 200 MB, so long reports and manuals do not need splitting. - **Custom dictionary:** Register your own glossary so product names, abbreviations and internal terminology always come out with the same wording. - **Unlimited translations:** Translate and download as often as you like on a flat monthly plan, and work with online files directly through the Chrome extension. - **Selectable AI engines:** Choose between Readable's own engine and a ChatGPT-based engine depending on the document, without paying separately for a translation subscription. **Strengths:** Keeps original PDF layout, so no manual rebuild of tables or diagrams; Unlimited translations on a flat monthly fee from 800 yen; Glossary registration keeps terminology consistent across a document set; Handles very large files (up to 1,000 pages / 200 MB on higher plans) [Profile (Markdown)](https://openaitools.app/tool/readable-jp.md) ## UPDF AI UPDF is a cross-platform PDF editor that positions itself as a practical alternative to heavier desktop suites, with an AI layer folded into the same interface. The core toolkit covers the whole document lifecycle: editing text and images, annotating, creating and filling forms, converting to and from Word, Excel, PowerPoint, and images, OCR for scanned files, and page organisation through merge, split, crop, and rotate. Protection features include passwords, redaction, sanitising, and removing restrictions, and an eSign workflow handles signers, fields, sending, and status tracking from draft to completion. Apps run on Windows, Mac, iOS, and Android, with one account covering up to four devices. UPDF AI is the intelligence layer built on OpenAI's GPT. It can summarise, translate, explain, and chat with a PDF, and you can scope work to the entire document, the current page, or a saved page range, or supply images as input. Beyond generic Q&A there are targeted assistants: a researcher mode breaks down novelty, limitations, methodology, and technical route; a contract mode flags key terms and potential risks with suggested clause improvements; a resume mode tightens wording and structure; and a finance mode interprets performance, major changes, and what deserves attention in a dense report. Additional smart features include AI semantic search, bookmark generation and summarisation, background and watermark generation, and a copilot for page management. Pricing follows a freemium pattern: the software can be downloaded and signed into for free access to features, with a risk-free trial before purchase and flexible yearly or lifetime plans plus a 30-day money-back guarantee. Enterprise, education, and individual plans are separated, and students and educators receive a discount. Security is addressed directly, with encrypted cloud storage in US and European data centres, SSL/TLS transfer, AI processing on US servers under OpenAI terms without personal data collection, and offline PDF tools for sensitive work. **Pricing & Plans:** Freemium with a free trial and paid upgrades. You can download UPDF and sign in to use features free, and try before buying. Paid access is available as yearly or lifetime plans with flexible options, covered by a 30-day money-back guarantee, and separate Enterprise and Education plans exist with roughly 52% education savings. UPDF AI is included in the paid offering rather than billed as a separate product. Check the pricing page for current prices, as promotions (for example 43% off campaigns) affect the listed figures. - **Full PDF editing:** Edit text and images directly, annotate ideas, add links and watermarks, and use OCR to make scanned PDFs editable — all inside one app instead of switching tools. - **Document-scoped AI:** Summarise, translate, explain, or chat with a PDF across the entire file, a single page, or a saved page range, so long documents stay manageable and answers stay focused. - **Role-based AI assistants:** Ready-made agents for researcher, contract, resume, finance, and study workflows analyse documents, surface risks and key terms, and suggest improvements. - **Convert, create, and organise:** Convert PDFs to Word, Excel, PowerPoint, or images, merge, split, crop, and rotate pages, and batch-process multiple files in a single pass. - **Protect, redact, and eSign:** Add passwords, redact sensitive content, sanitise metadata, then send documents for signature and track drafts, pending requests, declines, and completed agreements. **Strengths:** Genuinely cross-platform: Windows, Mac, iOS, Android, and web under one account for up to four devices; AI and PDF editing share one interface, so you can understand a document and then act on it without exporting; Strong conversion and OCR coverage, including scanned PDFs and batch processing; eSign workflow handles sending, field placement, and status tracking end to end [Profile (Markdown)](https://openaitools.app/tool/updf-ai.md) ## Frequently Asked Questions ### How do Readable and UPDF AI compare in monthly traffic?
