AI-translated. Then human-reviewed.
Built for documents of any length — from short briefs to thousand-page manuscripts and image-heavy PDFs that break other tools. Advanced retrieval, glossary locking, and context-aware models keep names and terminology consistent and preserve as much of the original layout as possible — then our marketplace connects you with a vetted human translator for a complete review.

How it works
Two phases. One workspace.
Upload your document and let the AI handle the heavy lifting. Then, when it matters, bring in a human expert for the final polish.
AI does the heavy lifting
- Understands your document structure, images, tables, and formatting
- Keeps names, places, and key terms consistent across hundreds of pages
- Adapts tone for children's books, academic papers, or business writing
- Flags areas where a human eye would add the most value
A human translator perfects it
- Browse our marketplace of vetted, language-tested professionals
- Send a direct offer or let the platform match the right reviewer
- The translator works inside the same workspace with full context
- Payment held in escrow until you approve the final result

How the AI works
Five layers of context guide every page — not just one big prompt.
Generic AI translators forget character names, drift in tone, and re-translate the same line three different ways. We learn your voice, lock your key terms, remember your world, reuse past translations, and flag the lines worth a second look — so a 500-page book reads as one consistent voice from start to finish.
Voice fingerprint
We read passages from your manuscript and learn how you write — sentence rhythm, register, dialogue cadence — then guide every page to sound like you.
Glossary lock
Lock character names, place names, and key terminology so they’re translated the exact same way every time they appear — no surprise renames halfway through chapter twelve.
Lore memory (RAG)
We map your story’s characters, places, and key facts up front, then quietly remind the AI of the relevant ones every time they come up — so personalities and details stay consistent.
Translation memory (RAG)
When a phrase appears again later in the book, we reuse the earlier translation instead of guessing fresh — the longer the document, the more consistent it gets.
Per-sentence confidence
Every sentence comes with a confidence score. Lines the AI is unsure about are highlighted in the editor so you (or your reviewer) know exactly where to focus.
Translator marketplace built in
Browse vetted professionals, send a direct offer, and let them review your AI draft inside the same workspace — no external hiring needed.
