Why It Matters
- BookTranslate.ai isn’t a gimmick. It’s a new standard for machine translation - delivering accuracy, nuance, and voice that leading tools missed.
- In our blind evaluation, BookTranslate.ai was rated higher than translations from DeepL, Amazon Translate, and Google Translate in terms of tone, structure, and faithfulness to the original.
- The test is fair and objective. All translations are evaluated under identical conditions by high-level AI language models - systems uniquely qualified to assess tone, fluency, and fidelity without bias.
- This process is fully transparent. Anyone can reproduce the experiment: generate translations for any language, anonymize them, and have top AI models score the results.
Don’t take our word for it. Upload your text and see how our recursive multi-pass system preserves clarity, tone, and structure - start to finish.
Experience the DifferenceHow to Reproduce This Benchmark
Our evaluation process is fully transparent and designed for independent verification. Here’s how you can run your own test - or audit ours:
- Use Grok 3, GPT-4o, DeepSeek V3, and Gemini 2.5 Pro as independent evaluators.
Claude does not allow longer prompts, which is a requirement for this evaluation.
Tip: For Gemini, use aistudio.google.com to avoid message truncation. - Select a text to translate and generate translations using DeepL, Google Translate, Amazon Translate, and BookTranslate.ai.
- Download our objective evaluation system prompt below, paste the four translations into the prompt, and pass it to the LLMs for evaluation.
- We selected Chinese as a difficult test case for machine translation from Latin-based languages - but you’re welcome to try any language pair.
All evaluations were conducted independently using publicly accessible AI systems.
