## FAQ

### How fast is it, and does it keep my meaning?

Most Japanese documents finish in under 25 seconds with your meaning intact — SupWriter changes how the Japanese is phrased, not what it says.

### Can SupWriter humanize Japanese content for this audience?

Yes. SupWriter handles Japanese natively and tunes the output to how Business professionals, executives, and sales teams actually work — passing detectors while reading like a native wrote it.

### What happens if my Japanese content is flagged as AI?

An email that reads machine-written erodes the trust a deal depends on — prospects stop replying, and a proposal that feels templated loses to a competitor who sounded human. Native-quality Japanese that clears detection is the way around that.

### Who will notice if this reads AI-written?

The recipient is the detector here: executives and buyers who process hundreds of emails a day develop a sharp instinct for AI-sounding outreach and simply ignore it. Human Japanese readers are even less forgiving of unnatural phrasing.

### Will the Japanese still sound right for this kind of writing?

Yes. The register — warm but businesslike first-person prose — direct, concise, and personal enough to feel written for one recipient — is preserved, and SupWriter renders it in idiomatic Japanese rather than a stiff translation of English.
