Frequently asked questions

qlot supports Microsoft Word (.docx), PowerPoint (.pptx), Excel (.xlsx), PDF, and Hangul Word Processor (.hwpx) formats. Tables, images, fonts, bullet points, and other formatting elements are preserved throughout the translation process.

qlot supports translation across more than 200 languages, including Korean, English, Chinese, Japanese, German, French, Spanish, Russian, and Vietnamese.

The Preview plan includes 1,000 credits per month with a 64MB file size limit. Paid plans expand these limits significantly.

qlot uses the latest frontier large language models to deliver translations that preserve the original meaning, tone, and formatting. For industry-specific or proprietary terminology, the Glossary feature lets you enforce consistent, pre-approved terms across every translation.

A glossary is a custom dictionary of terms and approved translations that qlot applies automatically, keeping your terminology consistent across all documents. Create a glossary in your dashboard, then add terms manually or upload them via CSV, and select the glossary you want right before starting a translation. Each glossary is configured for a specific language direction (for example, English to Korean).

Yes. qlot preserves your original layout. Your translated file downloads in the same format as the source file (Word, PowerPoint, Excel, PDF, or HWPX), keeping all tables, images, fonts, and structural layout intact.

Processing speed depends on the size and complexity of the document, but most standard files finish within seconds. Larger files may take a few minutes, and you can monitor progress in real time from your dashboard.

Yes. Image-only pages are detected and processed using text recognition, including mixed documents where only some pages are scanned. Results depend on the quality, resolution, and readability of the scan. When the original Word or Hancom document is available, uploading the source file will usually provide more accurate text extraction and formatting.

Translated text may take up more or less space than the original. qlot adjusts spacing, line breaks, and text placement to retain the document structure as closely as possible. Documents with highly complex layouts may still benefit from a final review.

You can edit the downloaded file using compatible PDF editing software. For documents that require extensive revisions, translating the original Word, PowerPoint, or Hancom file is recommended.

No. PDF translation runs in your browser, so no additional software or plugins are required.

qlot accepts Word documents in the .docx format. To translate an older .doc file, open it in Microsoft Word and select Save As > Word Document (.docx) before uploading.

Yes. Table-of-contents entries are translated while the underlying reference structure is retained. After downloading the translated document, update the table of contents in Word to refresh page numbers and other field values.

Tracked revisions and comments are translated together with the document. When only the final approved text should be translated, accept all changes and remove unnecessary comments before uploading.

Yes. The translated file is returned in the .docx format and can be opened, reviewed, and edited in Microsoft Word or compatible document software.

No. Formula cells are excluded from translation. Functions, expressions, and cell references remain connected to the original workbook data.

qlot translates text stored in standard text cells. Formula cells, numeric values, and date values are not translated. Text used in supported chart titles, axis labels, legends, and sheet names may also be translated.

Yes. All worksheets are processed together, with their order and individual structure retained. Terminology can be translated consistently across related sheets within the same workbook.

No. Numeric and date values remain unchanged. Existing display formats, including currency symbols, percentages, decimal formats, and date patterns, remain applied to their cells.

Chart structure, data series, cell formatting, merged ranges, borders, fills, and conditional-formatting rules remain in place. Supported chart titles, labels, and legends are translated with the workbook text.

Translated text may take up more or less space than the original. qlot adjusts font size and line spacing within the available text area to reduce overflow and retain the slide structure. Presentations with dense text or large differences in language length may still benefit from a final visual review.

Yes. Speaker notes are translated together with the content of their corresponding slides.

Supported text within tables is translated while the existing cell structure remains in place. Chart titles, axis labels, and legends are also translated while the underlying chart structure and data remain unchanged.

Existing object animations and slide transitions remain attached to the presentation. They are retained rather than rebuilt during translation.

qlot processes Hancom documents in the HWPX format. HWPX uses a structured document format that allows supported text, layouts, tables, and other document elements to be processed. To convert, open the .hwp document in Hancom Office, choose Save As from the File menu, and select HWPX Document as the file type, then save the converted file. Review the converted document before uploading, particularly when it contains complex formatting, WordArt, or other Hancom-specific objects.

qlot retains supported page layouts, table structures, merged cells, frames, page numbers, headers, and footers. When translated text requires more space, content is adjusted within the available layout. Documents with dense tables or complex proprietary objects may benefit from a final review.

Standard document text, tables, frames, footnotes, headers, and footers are processed with the document. Some proprietary objects, including certain WordArt elements, may be retained as images rather than translated as editable text.

Yes. The translation is returned as an HWPX file that can be opened and edited using compatible Hancom software.

All uploaded files are encrypted in transit using TLS and stored in AWS S3 with AES-256 encryption. Infrastructure is hosted on AWS (certified to ISO 27001 and SOC 2) with Cloudflare for additional network security.

Files and translations on paid plans are never used for AI training. Preview-plan content may be used, after de-identification, to improve our translation models — use any paid plan to exclude your content. Uploaded source files are automatically deleted within 24 hours of processing.

Data privacy is our top priority. qlot runs on infrastructure that is ISO 27001 and SOC 2 certified, and we comply with rigorous data-protection standards, including the Personal Information Protection Act (PIPA), to guarantee strict confidentiality and security for all corporate data.

You can permanently delete your account and all associated data from your account settings, or by contacting our support team at support@qtailab.com. Once processed, your files, glossaries, and personal history are permanently removed from our systems.

Enterprise plans include on-premises deployment, SSO integration, dedicated account management, and a service-level agreement. Please contact the qlot sales team through the Contact page to begin the procurement process.

Credits are deducted based on how much text your document contains and the language direction. A dense, full standard page runs 10–30 credits depending on the direction, and typical documents usually cost less.

It depends on the file's volume and the language direction. A typical 20-page document takes about 100–250 credits — roughly $0.21–$0.53 at the Pro plan's per-credit price ($0.0021). Upload a file and you'll see the exact credits before you commit.

No. If a translation doesn't complete successfully, no credits are used. If any were already deducted, they're returned automatically.

If you're not satisfied with a translation result, you can submit a credit refund request. Requests are reviewed individually, and approved credits are returned to your account. Using a glossary improves the consistency and quality of proper nouns and technical terms.

Credits refill on your monthly renewal date, and separate top-up purchases aren't offered. If you've used all your credits, you can wait for the next renewal or upgrade to a higher plan — the new credit allowance applies immediately when you upgrade.

No. Team credits are shared by the whole workspace. Seats × 20,000 credits per month are provided as shared credits, and every member draws from the same pool.

Yes. Scanned documents are translated after OCR text recognition. Credits are deducted by translation volume just like regular documents, and an OCR page limit may apply depending on your plan.

You can cancel your subscription at any time from your account's billing settings. Your plan remains active until the end of the current billing period, after which it will not renew.

Refunds are handled in accordance with our Terms of Service and applicable consumer protection law. To request a refund, please contact our support team through the Contact page.

Yes. You can upgrade or downgrade your plan at any time from your account's billing settings. Changes take effect according to your billing cycle.

Your credit allowance resets every month, and unused credits do not carry over to the next billing cycle.

The Preview plan is our trial: 1,000 credits every month at no cost, with no card required. Paid plans don't include a separate free-trial period — your first month is charged when you subscribe, and refunds are available under our Refund Policy.

Once you've used your plan's credits, translation pauses until your next billing cycle resets. To continue right away, you can upgrade your plan or purchase add-on credits. You will never face unexpected overage charges.

The Team plan is billed per seat. Each seat adds 20,000 credits per month to a shared organizational balance, and all members get access to unlimited shared team glossaries. Workspace admins can add or remove seats anytime from the dashboard.

Yes. On the Team plan, glossaries are shared automatically across all members, so your entire team translates with the same approved terminology.

Yes. qlot provides a translation API for integrating translation into your own systems and workflows. API access is available on the Enterprise plan. See our API documentation or contact our sales team for integration details.
