Japanese corporate filings have no English translation. Matsukaze uses AI to read full annual reports from EDINET and deliver structured English summaries in 60 seconds for $8.99. It detects subtle signals like disappearing boilerplate and shifts in management tone that translators miss.

Get full visibility into app health, errors, and performance

Hi, I built Matsukaze because I was tired of waiting weeks for English translations of Japanese filings — or paying thousands for them. The core insight: translation gives you words, but investing requires meaning. Japanese corporate filings are full of subtle signals — boilerplate phrases that appear or disappear, carefully chosen hedging language, unusual levels of confidence — that only make sense if you understand the culture and conventions of Japanese disclosure. Matsukaze uses Claude AI to read the full document (not a snippet) and produce a structured summary that highlights what matters to investors. There's a free sample PDF on the homepage (DISCO Corporation, a semiconductor equipment maker). Would love your feedback.

@matsukaze Interesting approach.

Congrats on your launch as well.

With tools like this, it feels like that first interaction is doing a lot of heavy lifting especially in helping users understand what they can actually do right away.

Have you noticed if people tend to get to that first usable outcome smoothly, or does it take a bit before it clicks?
