Lugji: Cantonese AI Notes
On-device meetings · private
Free · Designed for iPad. Not verified for macOS.
Lugji is now on iPad! Full-screen live transcript + Apple Pencil notes. On-device transcription needs iPhone 12 / equivalent iPad models or newer.
Let every conversation become knowledge you own.
Lugji is an on-device voice assistant built for English, Cantonese & Mandarin meetings. Recording and transcription run entirely on your iPhone, then write into your iCloud or the Obsidian vault you connect — no account, nothing sent to a processing server.
Lugji is serverless
Your content and keys never reach Lugji. No backend, no API keys, no tracking. Privacy here isn't packaging — it's a structural fact.
Core features
• Meeting recording & live transcription — one-tap recording for long meetings and interviews; Cantonese, Mandarin and English transcribed live with Apple's built-in on-device engine.
• AI summary (on-device · helper) — on Apple Intelligence–capable devices, Lugji can generate a meeting summary, processed entirely on your device: no Apple servers, no Private Cloud Compute, no cloud. (Requires iPhone 15 Pro or later; not available in mainland China.)
• Quick Notes — a thought, a whiteboard photo, a voice snippet: captured instantly as standard Markdown. Apple Pencil sketches, image text recognition (OCR · Traditional Chinese + English), and voice-to-text.
• Write into iCloud or Obsidian — every note is saved to your iCloud, or the local Obsidian vault you connect, with frontmatter and tags. Obsidian is your library; Lugji is the fastest way in.
Why on-device?
Cloud transcribers upload your audio to servers where it may be used to train AI; English-first models may be less suitable for Cantonese conversations; and they make you download 1–2 GB models and set up API keys. Lugji uses Apple's built-in engine, works in airplane mode, and is tuned for Cantonese meetings and everyday conversation.
Device requirements: on-device transcription needs iPhone 12 / iPhone SE (3rd gen) / iPad (10th gen) / iPad Air (4th gen) / iPad mini (6th gen) / iPad Pro (11" 3rd gen, 12.9" 5th gen) or newer. AI Summary requires an Apple Intelligence-capable device. Recording itself works on every supported device.
Pricing
Start free (with usage limits). Plus (unlimited) and Ultra (advanced security: on-device AES-256-GCM encryption for locked notes & recordings, key only in your iCloud Keychain · enterprise) are planned for a future update.
