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) ## ZeroGPT ZeroGPT is best known as an AI content detector, but the site has expanded into a full writing and verification toolkit. The core AI/GPT detector lets you paste text or upload a file and returns a highlighted analysis showing which sentences look machine-written, with a percentage gauge and an automatically generated PDF report you can use as documentation. Around that core sit several companion detectors and writers. The AI image detector and AI video detector extend checking beyond text; the plagiarism checker scans against billions of sources; and the AI humanizer and paraphraser rewrite text into a more natural style. A grammar checker, summarizer, translator, dictionary, word counter, citation generator, and AI email helper round out day-to-day writing tasks. The company says its multi-stage DeepAnalyse model is trained on internet text, educational datasets, and proprietary synthetic AI datasets, covers over 35 LLM families, and reports 98.4% detection accuracy with a false positive rate under 1%. Access is freemium: the main tools work free in the browser, with MAX and EXPERT subscriptions for heavier use and premium features, and a separate API for organizations that need large-scale integration. ZeroGPT also runs on WhatsApp and Telegram through a bot, letting you chat, detect AI text, summarize, paraphrase, translate, and check grammar without leaving the messaging app. **Pricing & Plans:** Freemium with paid tiers. Core tools such as the AI detector, summarizer, and grammar checker are usable free in the browser, while MAX and EXPERT subscriptions unlock higher limits and premium features, and API access is sold separately for organizations. - **AI and ChatGPT detection:** Paste up to 15,000 characters or upload a file and get a highlighted breakdown of which sentences appear AI-written, plus an overall percentage score and a downloadable PDF report. - **AI image and video detection:** Beyond text, ZeroGPT offers an AI image detector and an AI video detector that performs frame-level analysis to flag generated or manipulated visuals. - **Plagiarism checking and humanizing:** Compare your text against billions of sources through the plagiarism checker, or rewrite and humanize AI text with the paraphraser and AI humanizer while keeping the original meaning. - **Writing and productivity tools:** A bundled writing suite covers summarization, grammar and spelling correction, translation across many languages, a dictionary, word and character counting, citation generation, and an AI email writer. - **API for organizations:** A documented REST API exposes detection, plagiarism, paraphrasing, summarization, grammar, chatbot, and translation endpoints for organizations that need to embed ZeroGPT at scale. **Strengths:** Free browser access to the core AI detector, summarizer, and grammar checker; Sentence-level highlighting with an overall percentage and exportable PDF reports; Extends beyond text to AI image and video detection, plus plagiarism checking; Broad companion toolkit: humanizer, paraphraser, translator, dictionary, citations, email helper **Limitations:** AI detectors can produce false positives, so results should be treated as a signal rather than proof; The strongest features sit behind MAX/EXPERT paid tiers and API access is a separate purchase; Character limits apply to the free detection box; No detection tool can guarantee correctness across every model and language [Profile (Markdown)](https://openaitools.app/tool/zerogpt.md) ## Frequently Asked Questions ### How do Readable and ZeroGPT compare in monthly traffic?
