Speech bubbles are where other translators come apart: half translated, or clipped at the edge.
The models have caught up. Epoch AI found that the price of reaching a given level of AI capability fell between 9x and 900x per year, and responses now come back in seconds. That makes it practical to read the whole page first and translate every line with the full conversation in mind, so a translation can keep the feel of the manga.
You can also bring your own key (BYOK) if you'd rather pay your own provider. Requests go straight from your browser to OpenRouter, Google Gemini or OpenAI, and use zero NekoYaku credits.
My long-term goal is to spend no tokens at all. This doesn't exist yet. Once NekoYaku has a community, I'd like to build a place where someone who has already paid tokens for a finished translation can share the text, so the next reader can load or upload it and see it on the page right away. Translate once, read everywhere.
Hi Product Hunt! 👋
I'm Eunsang, the solo developer behind NekoYaku, a Chrome extension that translates manga right where you read it.
Why now: AI translation has gotten a lot cheaper and a lot more accurate. That changes what a translator can afford to do. Instead of handling one bubble at a time, NekoYaku reads the whole page first and translates every line together, in reading order. The dialogue fits the conversation and keeps the feel of the manga. Not long ago, doing that on every page would have been too slow and too expensive. Now it isn't.
Most tools I tried still hand back half-finished pages: half the bubble in English, an edge missing, and a wait to go with it. So I built the one I wanted to use.
What it does:
- Whole page: reads the full page in context, then translates every line together.
- One bubble: drag over it and read it in seconds.
- The art stays the artist's. Translations show up in small cards, and the page itself is left alone.
- 15 languages.
- Free to start. Bring your own API key if you'd rather use your own.
What I want to build next: a community where readers can share translations they've already generated. The next reader could load those translations instantly, without spending tokens or paying to translate the same page again.
My ultimate goal is to make NekoYaku a Chrome extension where readers can access shared translations for free. This is still a future goal, and I'd love to shape it with people here.
A question for the builders here: would you share a translation you'd already generated if it meant the next reader could use it for free? And what would make you trust a shared translation?
