## Multilingual.top (Langsany)

Multilingual.top is a free, browser-based AI translation platform. Today that domain serves Langsany, a translator whose defining idea is privacy by architecture: instead of sending your sentences to cloud servers, it runs open-source Opus-MT neural models locally through WebAssembly. That means confidential contracts, medical notes, or internal emails can be translated without uploading them anywhere, and you can even verify it yourself in your browser's Network tab.

The tool spans far more than plain text. It handles whole documents and e-books (PDF, Word, PowerPoint, Excel, EPUB) while preserving layout and chapters, translates images and scanned PDFs using on-device OCR, and transcribes audio and video with Whisper to produce bilingual SRT or VTT subtitles with timestamps kept intact.

It is completely free, with no account, subscription, or daily quota. The main practical trade-offs are a 5,000-character limit per text request, a slower first run on older phones while the model downloads and compiles, and routing through English when translating between two non-English languages. Once the model is cached, translation works offline and responds instantly.

**Pricing & Plans:** Free: no account, subscription, or daily quota. Text translation is limited to 5,000 characters per request. Offline use requires the neural model and page resources to stay cached, and clearing site data removes the downloaded models.

- **Free text translation:** Type or paste text and translate it instantly in your browser, with automatic language detection, up to 5,000 characters per request and no daily quota.
- **Document & e-book translation:** Translate EPUB, PDF, Word, PowerPoint, and Excel files while keeping chapters, layout, and formatting intact.
- **Image & OCR translation:** Read text from images and scanned PDFs with on-device OCR and draw the translation back onto the picture.
- **Subtitle & speech translation:** Transcribe audio and video with Whisper in the browser and produce bilingual SRT or VTT subtitles that preserve timestamps.
- **Private, on-device engine:** AI processing happens locally with open-source Opus-MT neural models, so your content never leaves your device and works offline once cached.

**Strengths:** Completely free with no account, quota, or subscription; Strong privacy: translation runs on-device with no content uploads; Covers text, documents, images, subtitles, and speech in one tool; Works offline after the language model is cached

**Limitations:** Text translation is capped at 5,000 characters per request, so long articles must be split; First use on an older or low-memory device is slow while the model downloads and compiles; Translation between two non-English languages routes through English, which can soften nuance; Quality is a step below large cloud models for subtle, high-stakes writing

## Readable

Readable is a Japanese AI translation service focused specifically on PDFs. 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)
