Let every conversation
become knowledge you own.
An on-device assistant built for Cantonese and Mandarin meetings. Every recording, transcription and organising step runs entirely on your iPhone — no Lugji server, no account, never sent to a processing server. Your content lives on your device and your own iCloud, or written into your Obsidian vault — your knowledge stays yours.
Lugji is serverless — your content never reaches Lugji
From spoken word to lasting knowledge
Record, organise and write into Obsidian — all on your device, no Lugji server.
Long meetings and interviews, captured the moment you finish
Start recording with one tap for long meetings or interviews. Cantonese, Mandarin and English are transcribed live, then saved automatically — all on your iPhone.
- Stable recording for long meetings and interviews
- Live transcription in Cantonese, Mandarin and English
- Saved automatically to on-device, iCloud or Obsidian
- Apple's built-in engine, fully on-device
Write into Obsidian · your knowledge stays yours
Every note is written as standard Markdown (.md) straight into your connected Obsidian vault, with frontmatter and tags. Not another closed notes app — Obsidian is your library; Lugji is just the fastest way in.
Sketches & drawing attachments
Draw, sketch or jot key points with Apple Pencil or your finger, then attach it to a note with one tap — stored alongside the text in the same .md.
Image text recognition (OCR)
Snap a whiteboard, business card or handwritten note, and Lugji recognises the text inside (Traditional Chinese + English) into the note body — a photo becomes searchable knowledge, not a static image.
Voice to text · the same commercial-grade Cantonese engine
Record a voice snippet inside a note and Lugji's core Apple engine transcribes it into the note on the spot — the same Cantonese recognition as meeting recording, not a second-rate model.
Fully on-device · no Lugji server
All of the above — transcription, recognition, organising — runs on your iPhone. No Lugji server, no account, nothing sent to a processing server. Privacy here isn't packaging; it's a structural fact.
Knowledge that connects, and gets smarter the more you use it
Every note is written into your Obsidian vault as a node in your knowledge graph. Over time, meetings, ideas and handwriting weave into a second brain that's entirely yours.
- A knowledge graph that makes the connections clear at a glance
- Full-text search to revisit any past conversation instantly
- Standard Markdown — your data belongs to you

FAQ
Anything else you'd like to know?
-
Does it support Cantonese?
Yes. It uses Apple's built-in on-device speech engine, running entirely on your iPhone. Cantonese is available now, with Mandarin and English rolling out.
-
Is it paid?
Lugji has three plans — Free (with usage limits), Plus (monthly, unlimited) and Ultra (tailored for regulated industries / enterprises). Final pricing will be confirmed at launch.
-
Does audio go to the cloud?
No. Recording and transcription run entirely on-device, and your audio stays on your phone. No servers, no API keys, no tracking.
-
How does it sync with Obsidian?
The iOS app uses iCloud Drive to write notes automatically into the 'Lugji Meetings' folder in your vault. Open Obsidian and they're already there — no plugin, no API key.
-
Do I have to use Obsidian?
No. Recording and transcription work on their own, and you can keep the Markdown yourself. But it's best paired with Obsidian — three months on, you'll still find the meeting you had today.
