The moment a pricing proposal goes into a free translator, your terms are on someone else's server.
Proposals carry pricing, discount terms, and competitive positioning. Paste them into a free translator and that information sits on a server outside your control. BizHonyaku never uses submitted data to train AI, and gets keigo right so your proposal reads as professional, not machine-translated.
A scenario like this happens often
Racing a deadline, Nakamura ran a proposal for an overseas prospect through a free translation tool. Only after hitting send did they realize the pricing table and discount terms had gone in as-is. Worse, the honorific tone came out stiff and literal — enough that the client might read it as a proposal nobody bothered to actually write.

Why free translators aren't built for sales proposals
Proposals and quotes carry pricing, discount terms, contract clauses, and competitive comparisons. Most free translation tools reserve the right to use submitted text to improve their service or train their models — deal-critical terms can end up outside your control without anyone intending it.
If pricing information reaches a competitor, it doesn't just weaken your negotiating position — it can expose price gaps between customers. Once uploaded, there's no way to pull the data back.
On top of that, the stiff, literal keigo free tools produce can read as a proposal nobody bothered to write properly — so a salesperson still ends up spending time checking and rewriting it anyway.
What BizHonyaku gives your sales team
Submitted data is never used for AI training
Proposals and quotes you upload are used only to produce the translation — pricing and terms never become training data.
Client-ready keigo and business tone
Accurate honorifics for proposal documents — not a literal word-for-word pass, but text you could actually send to the client.
Consistent product and plan names
Register your product and plan names in a custom glossary so the wording stays consistent across every proposal.
Word, PDF, and PowerPoint — as they are
Proposals in PowerPoint, quotes in Excel, pre-contract memos in PDF. Upload any of them and keep 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.
