## Doclingo

Doclingo is an online translation platform focused on content that ordinary translators handle badly: formatted documents, scans and images. Instead of returning a wall of plain text, it rebuilds the translated content inside the original page structure — headers, columns, tables and image captions stay where they were. PDF, Word, Excel, PowerPoint and image files such as PNG, JPG and WEBP are all supported, so contracts, research papers, product manuals and design drawings come back in a form you can still use.

The service pairs a layout engine with selectable AI translation engines, which means you can pick a model per job and watch your usage. OCR handles scanned pages and text baked into images, and every result can be reviewed in a bilingual view that places the translation under or beside the source. A built-in editor lets you fix terminology, and a glossary feature keeps recurring industry terms consistent across long projects. For collaborators and developers there is also a batch translation API.

Beyond the core document flow, Doclingo ships a browser extension for Chrome and Edge that translates WhatsApp and Telegram Web messages in place, a dedicated image translation mode with strict-layout and readability-first options, and a document chat that lets you ask questions about an uploaded file. There is a genuinely free tier with no signup required for standard translations, plus a paid PDF Pro track aimed at high-fidelity restorations and heavy OCR workloads, so the tool serves both occasional students and professional localization teams.

**Pricing & Plans:** Freemium-style with a no-signup free tier for standard document translation and a paid 'PDF Pro' tier for high-fidelity restoration, advanced OCR and larger volumes; an enterprise/API option exists. Check the site for current plan limits.

- **Layout-preserving translation:** Translated text is redrawn into the original document structure, keeping columns, tables, headings and images in place instead of producing a stripped-down text dump.
- **OCR for scans and images:** Recognises text in scanned PDFs, screenshots, photos, menus and posters, then translates it and puts it back into the image at the same position, size and colour.
- **Bilingual side-by-side output:** Read the source and the translation together, which makes reviewing terminology in contracts and academic papers far faster than flipping between files.
- **Wide format and language support:** Handles PDF, Word, Excel, PowerPoint and common image formats across 90+ languages, with batch processing for multiple files at once.
- **Browser extension for chat translation:** The Chrome/Edge extension translates WhatsApp Web and Telegram Web messages inline and can translate your own replies before sending them.

**Strengths:** Layout and formatting are genuinely preserved, which is the main weakness of most free translators; OCR handles scanned documents and text inside images, not just clean digital files; Free tier works without creating an account, lowering the barrier to trying it; Extras like bilingual view, glossary, online editing and chat translation make it a workspace rather than a one-shot converter

**Limitations:** Very large or complex files can take a while to process, and heavy OCR use pushes you toward the paid tier; The browser extension is desktop-only and cannot be installed on phones; Translation quality still varies by language pair and by which AI engine you select

## 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)
