# LangLang: Privacy-Focused Meeting Transcription App for iPhone An offline-first productivity tool that transcribes meetings and tracks commitments locally on your device. - **Source:** [Hacker News: Show HN](https://news.ycombinator.com) - **Published:** 2026-11-05 - **Topic:** [technology](https://brifing.si/c/technology) - **Original article:** - **On Brifing:** https://brifing.si/s/29137a87-f783-4f4d-92dc-a5cf52ed1cd8 ## Privacy-First Meeting Transcription LangLang is a productivity application designed for iPhone and Apple Watch that transcribes meetings directly on the device. By prioritizing local processing, the app ensures that no audio data is sent to external servers. This design choice eliminates the need for user accounts, tracking SDKs, or constant internet connectivity for core features. ## Offline Functionality and Security The application functions entirely in Airplane Mode, allowing users to record and transcribe conversations without an internet connection. Because all processing occurs on the iPhone, users maintain full control over their voice data. The app does not collect user data, adhering to strict privacy standards by avoiding third-party analytics and cloud-based storage. ## Tracking Promises and Deadlines LangLang automatically identifies commitments made during meetings, linking specific promises to the original audio source. Users can set reminders for these tasks, which function like alarms on iOS 26.1 or later. The app prompts users to confirm if tasks were completed, ensuring that follow-up items do not slip through the cracks. ## Meeting Minutes Generation With a single tap, the app converts recordings into structured meeting minutes. This summary includes attendees, key points, and a list of follow-up actions with associated deadlines. Users can copy this text for use in other apps or share it as a PDF or Word document if they have a LangLang+ subscription. ## Multilingual Support Capabilities The app supports English, Mandarin, and Cantonese, including meetings where languages are mixed mid-sentence. A notable feature allows users to switch Cantonese transcripts between spoken and written Chinese formats with one tap. This flexibility ensures that the transcription remains accurate and readable, even when speakers transition between different linguistic styles during discussions. ## Calendar Integration Features Users can connect their calendar to the app to enhance meeting preparation. Before a scheduled meeting, LangLang displays previous discussion topics and pending action items related to the participants. The calendar access is read-only, ensuring that the app does not modify existing schedules while providing helpful context for upcoming professional interactions. ## Speaker Identification and Learning LangLang identifies speakers and allows users to assign names to specific voices. The app learns from these corrections, improving recognition accuracy in future recordings. If a speaker is heard only once, the app asks for confirmation, such as 'Is this Sam?', rather than guessing, which helps maintain a clean and organized transcript history. ## Subscription and Free Tiers The free version offers unlimited recording, transcription, and playback, along with basic search and export functions. The LangLang+ subscription unlocks advanced features, including comprehensive key points for every conversation and cross-recording memory. Users can choose monthly or yearly subscriptions, or opt for a one-time lifetime purchase to access these premium capabilities. ## Hardware-Specific Optimizations The app is optimized for various iPhone models, including support for the iPhone Duo's folding display. On devices that do not support advanced key point extraction, the app provides a simplified list of follow-up sentences. This ensures that users on different hardware generations still benefit from the core promise-tracking and transcription features. ## Data Portability and Backups Users can export their entire history, including audio files, transcripts, and voice profiles, into a backup file. This allows for seamless restoration when switching to a new iPhone. By keeping backups in private locations, users retain ownership of their meeting history without relying on the developer's infrastructure for long-term data storage. ## Recent Version Enhancements Recent updates have improved the app's usability, such as titling recordings based on the first commitment mentioned rather than generic greetings. The interface now provides clearer visual feedback during recording, including live audio levels on the Lock Screen. Additionally, the app now retries transcription for segments that initially failed due to silence. ## Professional Impact and Utility LangLang serves as a specialized tool for professionals who require high privacy standards for sensitive meeting data. By automating the capture of action items and deadlines, it reduces the administrative burden of manual note-taking. Its offline-first approach makes it a reliable solution for users working in secure environments or during travel. ## Sources covering this story - https://apps.apple.com/us/app/langlang-live/id6812655455 — --- _Summary written by Brifing from the original reporting.
