The moment you paste a contract into a free translator, it leaves your company.
If your legal team is pasting contracts and NDAs into ChatGPT or Google Translate, that text is leaving your control. BizHonyaku never uses submitted data to train AI models, gets keigo and business tone right, and translates Word, PDF, and Excel files as they are.
Why free translators aren't built for contracts
Most free translation tools reserve the right to use submitted text to improve their service or train their models. Clauses from an NDA or contract can end up in logs or training data you have no visibility into.
Contracts carry deal terms, pricing, penalty clauses, and confidential information about both parties. Once that text is sent to a third-party server, it's outside your company's access controls and security policy.
On top of that, free tools routinely mishandle Japanese business honorifics and contract-specific phrasing, so legal ends up spending time re-checking and correcting the output anyway.
What BizHonyaku gives your legal team
Submitted data is never used for AI training
The contracts and NDAs you upload are used only to produce the translation — never to train any AI model, and never for any other purpose.
Keigo and business tone built for contracts
Correct honorifics and standard contract phrasing, reproduced accurately — not a literal word-for-word pass, but text you could actually send to the counterparty.
Word, PDF, and Excel — as they are
Contracts in Word, price schedules in Excel, signed documents in PDF. Upload any of them and get a translation that keeps the original layout.
Security
SSL-encrypted transfer
Uploaded files are transferred over SSL encryption.
Encrypted storage
Files are stored encrypted in Supabase Storage.
Never used beyond translation
Your data is never used for any purpose other than producing your translation — including AI training.
