Why teams switch to Ellon AI

Formatting is the product

Ellon AI was built for documents, not text. Tables, footnotes, headers, multi-column layouts, and signature blocks survive translation. DeepL's document feature handles basics but struggles with complex layouts.

Zero data retention

Toggle zero-retention and your document is deleted immediately after download. DeepL Pro deletes after translation, but free tier documents may be used for training.

More than translation

Ellon AI includes document comparison (redlining), PII redaction, and contract analysis. DeepL is translation-only — you need separate tools for the rest of your workflow.

PDF-native processing

Ellon AI converts PDFs via Adobe's services before translation, preserving the original structure. The result is a properly formatted PDF, not a text dump with broken tables.

200+ vs 33 languages

DeepL supports 33 languages with high quality. Ellon AI supports 200+ language pairs by leveraging multiple AI models (Claude, Gemini, GPT) and selecting the best for each pair.

Batch and multi-language

Upload multiple documents and translate them into multiple languages in a single job. Each document × language combination runs in parallel.

Frequently asked questions

Is Ellon AI's translation quality as good as DeepL's?+

For most language pairs, yes. Ellon AI uses multiple AI models (Anthropic Claude, Google Gemini, OpenAI GPT) and selects the best one for each language pair and document type. For the 33 languages DeepL supports, quality is comparable. For the 170+ languages DeepL doesn't support, Ellon AI is the only option.

Does DeepL preserve document formatting?+

DeepL offers basic document translation for Word, PowerPoint, and PDF. However, complex layouts — multi-column PDFs, nested tables, footnotes with cross-references, signature blocks — often break. Ellon AI's core product is formatting preservation.

Can I try Ellon AI before committing?+

Yes. The free trial includes 20 pages with no credit card required. Upload a document you've previously translated with DeepL and compare the formatting quality.

Is Ellon AI more expensive than DeepL?+

Ellon AI's Starter plan is $19/month for 100 pages. DeepL Pro starts at $8.74/month for text translation, with document translation available on higher tiers. The price difference reflects the formatting preservation, redaction, comparison, and analysis tools included.

Can I switch from DeepL without losing anything?+

Yes. Ellon AI doesn't require migration — just upload your documents. If you use DeepL's API, Ellon AI's REST API covers the same translation endpoints plus redaction, comparison, and analysis.
