Koma Lens

KomaLens lets you select any area of your screen — a manga panel, a manhwa or manhua bubble, a subtitle, a sign in a video, text in a game — and get an instant translation with a short explanation, right where you're reading. - Works everywhere, not just manga sites Because KomaLens works from what's actually rendered on your screen, it works on sites that DOM-based tools can't reach (protected readers, image-based comics, video overlays, screenshots, games) — as well as anywhere else you'd want quick language help. - Bring Your Own Key (BYOK) KomaLens connects to OpenRouter using your own API key. No subscription, no account, no login. You choose the AI model, you control the cost — pay only for what you use, from fractions of a cent per capture with lightweight models to top-tier models for tricky pages. - Built for language learners Beyond a raw translation, KomaLens gives you a short explanation aimed at helping you actually learn — not just read and forget. Additionally, you can save and export your favorite words to easily review them in apps like ANKI. - Privacy first * No backend server. There is nothing to hack, log, or leak, because nothing is stored anywhere but your own device. * Your API key and settings are stored only in your browser's local storage. * Your selected image is sent directly from your browser to OpenRouter — never through any server we operate. * No tracking, no analytics, no ads. - Supported languages Japanese and Chinese - Getting started * Create a free account at openrouter.ai and generate an API key. * Add a small amount of credit. * Paste your key into KomaLens' settings and pick a model. * Select any text on screen and get your translation.
