Messages that land wrong

Grammatically perfect can still be culturally wrong — the missing cushion before a refusal, the misread soft no. Ishin catches it before your client does.

how it's built

  • ·Per-direction models — a fast model EN→JP, a stronger one JP→EN, both streaming.
  • ·Naturalness check — a second mode verdicts your own JP or EN: ✓ natural / ⚠ with a fix.
  • ·Hardened prompts — injection-resistant, snapshot-tested so a stray edit fails CI.
  • ·Golden-case evals — every field bug becomes a permanent regression case.
  • ·Next.js · Clerk · Supabase — installable PWA with a hand-rolled service worker.
