ToneBridge
Rewrite work messages into the right tone, in 4 languages
Working in a second language? The hard part isn't translation — it's tone. ToneBridge rewrites your draft into the right workplace tone across Korean, Japanese, English & Chinese, with 8 tone modes — and explains why. Free to start, right inside Gmail, Slack & LinkedIn.
Hi PH! 👋 Maker here.
I work in Japan in a non-native language, and the hardest part of every day wasn't the work — it was hitting "send." Too direct? Too formal? Will this read as rude? I'd lose 10 minutes on a one-line message.
Translators fix *meaning*. Nothing fixed *tone* — the keigo, the politeness, the distance. So I built ToneBridge: paste a rough draft, get it rewritten in the right workplace tone across KO/JA/EN/ZH, with 8 modes, and it explains *why* so you actually learn. It works right inside Gmail/Slack/LinkedIn via a Chrome extension (Ctrl+Shift+Y).
Solo-built — Next.js + Claude Haiku, Cloudflare. Free tier: 10 rewrites/month, no password (magic link).
I'd love brutal feedback on whether the value lands in the first 10 seconds. AMA about the build too 🙏
