About BookTranslator

FreemiumBeginner-friendlyNo APIWeb

BookTranslator is an AI-powered translation tool built specifically for books and long-form documents. It supports file formats including EPUB, PDF, DOCX, MOBI, TXT, and SRT, translating into 140+ languages while preserving original layout, tables, images, footnotes, and formatting. Built-in OCR handles scanned PDFs and image-only files, making even old scans translatable. The tool is designed for whole-book context, capturing tone and nuance across passages, and includes an auto-glossary that ensures consistent translation of names, places, and key terms from first page to last. Over 834 million words have been translated by more than 2,500 users from universities and publishing houses. BookTranslator offers a free tier with 1,000 trial credits, a pay-as-you-go option ($1.99 per task, calculated per word), credit packs that never expire, and a Pro subscription billed annually with monthly credits. It saves time and money compared to manual translation, delivering a readable output without manual cleanup. However, it lacks an API, local desktop client, and real-time translation capabilities, making it best suited for one-off book-length projects rather than ongoing integration or conversational needs.

Behind the Verdict

BookTranslator fills a specific niche: whole-book translation with layout preservation. Its strengths are OCR for scanned PDFs, auto-glossary for consistent terminology, and support for 140+ languages. Weaknesses include no API, no desktop app, no real-time translation, and a 300MB file cap. For one-off book projects, it's more affordable than human translation; but for teams needing integration or batch processing, alternatives like Smartling or memoQ are better.

Plans compared

For each published BookTranslator tier: who it actually fits, and what it adds vs. the previous tier. Cross-reference the cost calculator above for projected annual outlay.

Pay as you go

$1.99/task

Ideal for

One-time users who need to translate a single book and don't want to commit to credits or a subscription.

What this tier adds

Starting tier: no subscription, pay per task, but limited to 300K words per task and 7-day history.

Free

$0/mo

Ideal for

First-time users evaluating the tool with 1,000 free trial credits; light users who buy small credit packs.

What this tier adds

Adds credit system and 30-day history over Pay as you go; free credits to start.

Pro (Billed Annually)

Custom

Ideal for

Heavy translators who translate multiple books per month and want priority speed and lower per-credit cost.

What this tier adds

Adds monthly credit allowance, priority speed, and permanent history vs Free; annual commitment required.

One-time Credits

$10 for 20,000 credits

Ideal for

Anyone wanting a simple prepaid option without subscription; credits never expire.

What this tier adds

Standalone credit pack available to all users at flat rate, no subscription or plan needed.

Hidden costs & gotchas

What the public pricing page doesn't put in bold. Captured from pricing-page footnotes, contract terms, and recurring complaints.

  • On the pay-as-you-go plan, going over 300,000 words per task requires adopting the credit system or Pro subscription.
  • The free tier only includes 1,000 trial credits; you'll need to buy credits or subscribe for any real project.
  • Pro pricing is only available billed annually, so you commit upfront for monthly credits.
  • Credits purchased on the free tier expire after 30 days for history storage, but purchased credits themselves never expire.

Where the pricing makes sense

The company stage and team size where BookTranslator's pricing actually pencils out — and where peers do it cheaper.

BookTranslator's pay-as-you-go ($1.99/task) and credit packs ($10 for 20,000 credits) fit occasional book translators. For heavy use, the Pro plan (annual billing) offers lower credit rates, but there's no monthly subscription option. Compared to human translation, it's far cheaper; but compared to tools like Google Translate (free for short texts), it's overkill for small jobs.

Setup time & first value

How long it actually takes to get something useful out of BookTranslator — broken out by persona, not the marketing-page minute.

For a single book upload: create account (1 min), upload file (1-5 min depending on size), set options (1 min), translation completes in minutes to an hour depending on length. First value in under 10 minutes for most files.
