Big Announcement: Neural Lens is Now 100% Free!

Today, we are thrilled to make a major announcement: Neural Lens is removing all subscription paywalls and is now completely free for everyone!

This is not a temporary promotion or trial. It represents our long-term commitment to making advanced AI translation accessible to students, researchers, developers, and avid readers worldwide without financial barriers or usage limits.

Starting today, all features previously reserved for Pro subscribers—including unlimited high-precision screenshot OCR, layout-preserving PDF translation, and 100% private local offline translation models—are open to everyone at no cost.

Why We Are Going Completely Free

Over the past months, we've realized how essential high-quality translation tools are for daily productivity. However, many AI-powered translation tools on the market are locked behind expensive monthly plans or place strict limits on how many screenshots or documents you can translate each day.

We believe that essential productivity tools should not become a financial burden for research, learning, and development.

Instead of managing complex billing systems and limiting user usage, we want to return to the core of what a tool should be: fast, reliable, private, and simple. We have hidden all in-app purchases and paywalls, immediately granting full premium Pro access to all new and existing users.

Neural Lens Core Features Overview

Neural Lens is designed as an integrated translation ecosystem that connects your browser, desktop apps, offline privacy, and document layouts. Here is a recap of what you can do:

1. Selected Web Text Translation (Browser Extension)

• Ready to Use: Install our official Chrome/Edge extension to instantly translate words or paragraphs on any webpage upon text selection.
• Zero Configuration: Translate instantly with our built-in free engines without having to sign up or configure API keys.

2. High-Precision Screenshot OCR & Translation

• Need to translate text from images, scanned papers, locked documents, or webpages that prevent copying? Simply trigger the global shortcut (Option + Shift + O on macOS).
• Powered by macOS native Vision framework and Windows high-performance OCR libraries, it grabs text on your screen within milliseconds and translates it immediately.

3. BabelDOC PDF Layout-Preserving Translation

• No More Broken Formats: Traditional translation tools often break layouts, tables, and mathematical formulas in PDF documents.
• Neural Lens leverages our advanced BabelDOC multidimensional coordinates engine to translate your PDFs while fully preserving their original visual layout. You can export translated versions or bilingual side-by-side PDFs.

4. Top AI Models & Custom API Key Integration

• We natively support top-tier AI models including OpenAI (GPT-4o), Claude (3.5 Sonnet), DeepSeek, Gemini, Groq, and OpenRouter.
• You can plug in your own API keys to query these models at raw developer rates, customizing the tone and style of your translations.

5. 100% Private Offline Translation

• Zero Data Leakage: For sensitive business or legal documents, activate our local offline engine (utilizing MarianMT and the lightweight Tencent HunYuan translation model).
• All translation runs locally on your computer's CPU/GPU. No data ever leaves your device, and it works perfectly even without an internet connection.

6. Cross-Platform Desktop Client

• Built on a lightweight Rust backend and a modern React/TypeScript frontend, Neural Lens is fully optimized for both macOS and Windows desktop environments.
