## 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)

## SciSpace

SciSpace began as a typesetting and paper-formatting service called Typeset and has since grown into a broad AI research platform. Its core promise is that a researcher can move from finding a paper to understanding it to citing and writing about it without leaving one workspace. The platform indexes scholarly content from sources such as Google Scholar, PubMed and arXiv, and layers AI agents on top for reading, extracting data and synthesis.

The signature capability is conversational reading: you upload or open a PDF, then ask questions, highlight confusing sentences for plain-language explanation, or request structured summaries of methods, results and limitations. Around that sit task-specific tools — Literature Review, AI Writer, Paraphraser, Citation Generator, AI Detector, AI Humanizer, Extract Data and a Plagiarism Checker — plus a Chrome extension that adds the same assistant on top of publisher pages and a mobile app for reading on the go.

Access follows a freemium model: exploring and limited usage are free, while paid Premium, Advanced, Max and Enterprise plans raise model quality, credit limits and parallel agent capacity. The company is registered as PubGenius Inc. in Milpitas, California, and markets the product to individual researchers as well as universities and enterprises with SSO and admin controls.

**Pricing & Plans:** Freemium. A free tier with limited usage sits alongside paid Premium (~$12/month billed annually), Advanced (~$70/month) and Max (~$160/month) plans; monthly billing is higher. Enterprise pricing is custom. All plans advertise a 24-hour money-back guarantee, and annual billing carries a discount.

- **Chat with PDF:** Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
- **Literature Review and paper search:** Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
- **Writing, paraphrasing and citations:** An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
- **Extract Data and AI Detector:** Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.
- **Chrome extension and mobile app:** Use the same assistant on top of publisher sites and PDF pages via the browser extension, or read and query papers from the mobile app.

**Strengths:** Combines paper discovery, reading, writing and citation tools in one place instead of five separate subscriptions; Conversational explanations of difficult passages are genuinely useful for non-native English readers and cross-disciplinary work; Covers widely used scholarly sources such as Google Scholar, PubMed and arXiv; Free tier plus a Chrome extension make it easy to evaluate before paying

**Limitations:** Credit-based limits can be confusing, and heavy users report hitting caps on the cheaper plans; Model access varies by tier, so the cheapest paid plan does not get the strongest reasoning models; AI-generated reviews and paraphrases still need careful human checking for accuracy and citation integrity
