Point at foreign text, see translation overlaid instantly

The Problem

Foreign text is inaccessible; Google Translate requires photos and waiting; roaming data is expensive

Current Solutions (Not Great)

Google Translate camera (cloud, slow), typing text manually, asking strangers

Who Needs This

Travelers, immigrants, language learners, international business travelers, expats

You're in a foreign country staring at a menu, a sign, a document. Lens Translate gives you instant understanding: point your camera at any text and see the translation overlaid right on the image, as if it were written in your language. Real-time translation that follows the text as you move the camera. Works on signs, menus, documents, product labels, anything with text. Because it's local, it works without roaming data and your location/context isn't tracked.

Honest Take

Google Translate already nails this with their camera feature, including real-time AR overlay and offline support for many languages. You'd be competing against Google's massive model quality and language coverage, which is a tough fight. The local-first angle helps, but most travelers already trust Google Translate and it works well enough that switching costs are high.

Build Prompt

Use this prompt with an AI assistant to start building

Build a React PWA called 'Lens Translate' using WebInfer with vision capabilities. UI: live camera view with translation overlay, language pair selector, history tab. Live mode: continuous camera feed via getUserMedia. Process frames at ~5fps for performance. For each frame, detect text regions. Use generateObject to return { textRegions: [{ text: string, language: string, boundingBox: {x,y,w,h}, translation: string }] }. Render overlay on canvas positioned over camera feed: for each text region, draw translated text in matching position (same size, orientation). Match styling: try to use similar font size, maintain readability with background. Smooth updates: don't flicker translations, persist until text moves significantly. Language settings: source (auto-detect or specify), target (user's language). Photo mode: capture still image, higher quality analysis, copy translated text. History: recently translated phrases saved for reference. Dictionary: tap any translated word for detailed definition, examples, pronunciation via speechSynthesis. Offline: ensure model + language pairs downloaded, works without network. Conversation mode: two-way translation for back-and-forth communication.
