## O.Translator

O.Translator is a cloud translation platform built around one idea: translations should be usable immediately, without manual reformatting. You upload a document, pick a target language and a translation mode, and the service returns a translated file that retains headings, tables, columns, images and general visual structure. It accepts more than 50 file formats — PDF, DOCX, PPTX, XLSX, EPUB, HTML, TXT, CBZ/CBR comics and more — with uploads up to 1 GB, and covers over 100 languages.

The service leans on leading large language models for translation quality and adds document-aware tooling on top. A preview step translates part of the file first so you can check terminology, tone and layout before committing to a full run, and a glossary system keeps brand names and specialist terms consistent across a project. OCR handles scanned PDFs and text embedded in images, and subtitle translation converts audio or video into translated captions. Team and enterprise plans add shared translation projects and glossaries so reviewers work from a common reference.

Pricing is usage-based rather than subscription-based: you buy credits and spend them on tokens, a document analysis fee and the model mode you select. Standard mode is inexpensive and fine for everyday documents, while Professional mode uses higher-tier models for contracts, academic papers and business reports. Because cost depends on the file, every task shows a quote before you confirm, and you can evaluate the preview before spending anything. The company is based in Delaware, USA.

**Pricing & Plans:** Pay-as-you-go credit system with no monthly fee. Single credits cost about $0.13 each with a 15-credit minimum; a $5 pack gives 40 credits, $15 gives 120 and $60 gives 480. Standard translation costs 1 credit per 3,000 tokens plus a document analysis fee (minimum 2 credits for a full paid translation), while Professional mode costs roughly 3x that. Credits never expire, and there is also an Enterprise Edition with shared projects and glossaries.

- **Layout-preserving document translation:** Translate PDF, Word, PowerPoint, Excel, EPUB, HTML and 40+ other formats while keeping headings, tables, columns and images in their original positions.
- **Preview before you pay:** Translate a portion of the file first to inspect terminology, tone and layout, then review the quote and confirm the full task only if the result looks right.
- **Glossary and editing controls:** Define terms and rules for brand names and specialist vocabulary, and edit the translation online so wording matches your audience.
- **OCR, comics and subtitles:** Recognize text in scanned PDFs and images, translate CBZ/CBR comics in one click, and turn audio or video into translated subtitles.
- **Translation API and team workspace:** Connect via a developer API for automated pipelines, and share translation projects and glossaries across a team or enterprise account.

**Strengths:** Output keeps the original document formatting instead of degrading into plain text; Preview and per-task quotes remove the risk of paying for a bad translation; Credits never expire and there is no monthly subscription commitment; Broad format coverage (PDF, Office, EPUB, comics, subtitles) in one tool

**Limitations:** Costs are token-based and harder to predict than flat per-document pricing; Document analysis fees and OCR estimation add a layer of pricing complexity; Uploaded and translated files are deleted after 15 (unpaid) or 30 (paid) days

## 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)
