Plae

Product Introduction

1. Definition: Plae is a native macOS menu bar utility designed for on-device text translation. It operates locally on the user's Mac, eliminating the need for cloud processing or internet connectivity after initial setup.
2. Core Value Proposition: Plae exists to provide instant, private translation directly accessible via a global keyboard shortcut (Cmd+Shift+T) from any application. Its primary value lies in offline translation privacy, speed (especially using Apple Translation), and seamless workflow integration without requiring app switching or accounts.

Main Features

1. On-Device Translation Engines:
   • Apple Translation: Utilizes macOS's built-in Neural Engine for native-quality translation across 19 languages. Offers sub-second translation speed, zero setup, and works fully offline after language pack download.
   • Apple Intelligence: Leverages Apple's advanced contextual understanding for better handling of slang, nuance, and more languages than Apple Translation. Requires macOS Tahoe (or later) with Apple Intelligence enabled. Runs entirely on-device.
   • Built-in AI Model: Ships with an independent, locally-run AI model (Google's TranslateGemma via llama.cpp). Users choose between 4B, 12B, or 27B parameter models supporting 55 languages. Downloadable once, works fully offline forever on any compatible Mac, no Apple-specific features required.
2. Privacy-First Architecture:
   • Zero Data Transmission: All translation processing (regardless of engine chosen - Apple Translation, Apple Intelligence, or Built-in AI) occurs locally on the Mac. No text, queries, or results are sent to external servers or cloud services.
   • No Tracking: Plae collects zero analytics, telemetry, or user data. No accounts are required, ensuring complete anonymity.
   • Offline Operation: After the one-time download of necessary language packs (for Apple Translation/Intelligence) or the AI model, all functionality works without an internet connection.
3. Efficient Translation Workflow:
   • Global Shortcut (Cmd+Shift+T): Instantly activates Plae's translation window from within any application without switching context.
   • Full-Screen Presentation Mode: Tap the present button to display the translation in a large, clear format readable from a distance, ideal for showing others.
   • Translation History: Automatically saves the last 20 translations. Users can star entries to permanently save them for quick reference.
   • Language Swap: One-tap button to instantly reverse the source and target languages for bidirectional conversation flow.

Problems Solved

1. Privacy Concerns in Translation: Solves the problem of sensitive text being sent to third-party cloud servers, addressing risks of data leaks, surveillance, or misuse by translation providers. Essential for confidential business communications, personal conversations, or users in regions with strict data privacy laws.
2. Workflow Disruption & Slow Translation: Eliminates the friction of switching between applications or opening browser tabs for translation. Provides near-instant results (especially with Apple Translation), significantly faster than cloud-based services requiring network round-trips.
3. Offline Translation Needs: Provides reliable offline translation capability crucial in situations with poor or no internet connectivity (airplanes, remote locations, secure networks). Removes dependency on continuous cloud access.
4. Target Audience:
   • Multilingual Individuals & Families: For daily communication between speakers of different languages at home.
   • International Teams & Businesses: For quick verification of messages, on-the-spot translation during meetings, or displaying translations for colleagues.
   • Frontline Staff & Shared Spaces: Hotel receptionists, coworking managers, or hostel staff needing to communicate quickly with guests speaking different languages.
   • Expats & Language Learners: Individuals navigating daily life or studying in a new language environment, requiring instant, private translation support.
   • Privacy-Conscious Professionals: Lawyers, journalists, healthcare workers, or anyone handling sensitive information requiring confidential translation.

Unique Advantages

1. Differentiation vs. Cloud Competitors: Unlike web-based translators (Google Translate, DeepL web) or apps relying on cloud APIs, Plae offers unmatched privacy (everything on-device), consistent offline functionality, and faster speeds for supported languages via Apple Translation. Its one-time purchase model contrasts sharply with subscription-based services.
2. Differentiation vs. Other Local Apps: Plae uniquely integrates multiple on-device engines (Apple's native tech + a powerful independent AI) in one streamlined menu bar app. The global shortcut activation and full-screen presentation mode are highly optimized for macOS workflow efficiency.
3. Key Innovation: Plae's core innovation is its seamless orchestration of diverse on-device translation technologies (leveraging Apple's frameworks and independent AI via llama.cpp) under a privacy-guaranteed, zero-configuration (for Apple Translation) menu bar interface accessible instantly from anywhere. The inclusion of a downloadable, user-selectable offline AI model (TranslateGemma) provides unparalleled language support flexibility without cloud dependence.

Frequently Asked Questions (FAQ)

1. Does Plae send my text to the internet or store it? No. Plae performs all translation processing locally on your Mac. No text you input, nor the translations generated, ever leave your device. There are no servers, databases, or cloud storage involved. It's truly private translation.
2. Can Plae translate without an internet connection? Yes, absolutely. After the one-time initial download of the required language packs (for Apple Translation or Apple Intelligence) or the built-in AI model, Plae works completely offline. No ongoing internet connection is needed for translation functionality.
3. What languages does Plae support for offline translation? Plae supports 19 languages via the fast Apple Translation engine (Arabic, Chinese, Dutch, English, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Thai, Turkish, Ukrainian, Vietnamese). Using Apple Intelligence expands support further. The Built-in AI model supports 55 languages offline. You can switch engines in settings based on your language needs.
4. How fast is Plae compared to online translators? When using Apple Translation, Plae is often faster than online services because it leverages the Mac's Neural Engine locally, eliminating network latency – results appear in under a second. The Built-in AI models (4B, 12B, 27B) take a few seconds depending on model size and your Mac's hardware, comparable to some cloud services but with full privacy.
5. What macOS version do I need for Plae? Plae requires macOS Sequoia (macOS 15) or later. Using the Apple Intelligence translation engine additionally requires macOS Tahoe (or later) and Apple Intelligence to be enabled on your system. The core app and Built-in AI model work on Sequoia without Apple Intelligence.
