Pin a live translation popup to any page region — chat, subs, tickers. On-device AI by default; optional Cloud LLM for top quality. PaneTrans pins a glass translation popup to any region of any web page — and keeps it live. Drag a rectangle over a live chat, video subtitles, a stock ticker, a comment feed; the popup shows the original and the translation side by side and re-translates the instant the text changes. Like clipping a real-time subtitle strip onto any slice of the page. WHAT MAKES IT DIFFERENT • Persistent, not one-shot. The popup follows the region until you close it. • Tracks live content with a MutationObserver, and auto-falls back to OCR for video frames / images / canvas. • Caption-bar mode: subtitle-shaped regions render as a real second subtitle track under the video. • Multiple regions at once — each gets its own draggable popup. ON-DEVICE BY DEFAULT The free and Pro tiers run entirely in your browser with local AI models (Transformers.js + ONNX). No API key, and your text never leaves your device — works offline once a model is cached. • Free: OPUS-MT (real-time on WebGPU), NLLB-200, M2M-100 — 10+ languages. • Pro ($14.99 lifetime or $2.99/mo): on-device LLM models Qwen 3 and Gemma 3 for the most fluent local output. NEW — OPTIONAL CLOUD TIER ($4.99/mo) Want top quality on a device with no GPU and nothing to download? The optional Cloud subscription streams a hosted large language model, with tokens appearing as they translate. Because it runs on a server, the Cloud tier sends the text you translate to our service to produce the result (we meter usage but don't store your text). The free and Pro tiers stay 100% on-device — Cloud is a deliberate opt-in. PRIVACY No ads, no analytics, no telemetry. We never sell your data. On the free and Pro tiers nothing you translate is transmitted. The only network calls there are model downloads (Hugging Face) and license validation.
