Hold your meetings in Cantonese and Lugji records and transcribes them on your iPhone. When you need a document, Lugoffice turns spoken Cantonese into formal written Chinese. Your whole company's meeting memory goes into your own Lugbox (business pilot). Three products, one path — and at every step we spell out what stays on your device and what goes out.
On the App Store Lugji · Lugoffice · iPhone and iPad · Lugbox business pilot
Casual Cantonese in. Formal documents out.
Start by capturing with Lugji. Open Lugoffice when you need a document. When the team needs to find what was said before, move up to Lugbox (business pilot). Each one works on its own.
Lugji Cantonese meetings, interviews, ideas — one tap to record, transcribed on your iPhone and saved where you choose: on your iPhone, in iCloud or in Obsidian.
Lugoffice Turns Cantonese transcripts into formal written Chinese you can hand in: minutes, notices, formal email, reports, weekly reports.
Lugbox An AI box that sits in your office. Add the meeting records and documents you choose, and colleagues type questions in Cantonese to find what was said and decided before — with sources.
Recording → transcriptTranscript → formal documentDocument → company knowledge base
Lugji · Transcription & AI notesBuilt for Cantonese meetings. No account. No Lugji server. Transcription and summaries run entirely on your iPhone; your notes live in your own iCloud Drive as plain Markdown. AI summaries are in Beta and need an Apple Intelligence model (iPhone 15 Pro or later). Save each note where you like — on your iPhone, in your own iCloud, or straight into your Obsidian vault. With Obsidian, you can still find what a meeting covered three months later.
Lugoffice · Meetings → documentsYou think in Cantonese, but what you hand in has to be formal written Chinese. From one conversation, Lugoffice produces the documents you need.
「咁呢個 project 我哋下個禮拜三之前要 confirm 咗個 budget 先。Amy 你跟一跟供應商嗰邊，報價要齊三間㗎。場地我哋暫時揀返禮堂，家長嗰封信我聽日出。」
Demo content, not real client data. Actual output depends on the app. Lugoffice writes in formal Chinese.

One table says it all. The three products handle privacy differently, so we won't sum them up with one “everything stays local” line — every cell spells it out.

If Lugji is connected to Obsidian and your vault lives in iCloud, notes sync to your own iCloud Drive. If documents in Lugbox were organised with Lugoffice, that step used cloud AI: the text passed through our relay server in Hong Kong (the relay stores no content) to Google Vertex AI; under Google's enterprise terms, your data isn't used to train AI models. Full details: for Lugji, see our Privacy Policy; for Lugoffice and Lugbox, see the Lugoffice Privacy Policy.
Started in Hong Kong, built for the way Hong Kong talks. No tech for show — just the pile of work that comes after every meeting.
Mixed Chinese and English, colloquial speech, industry jargon — that's what Hong Kong meetings really sound like. Lugji and Lugoffice put Cantonese first from day one; they're not English apps with a translation bolted on.
No Lugji server — we don't have your content. Lugoffice sends only the text you choose. Lugbox sits in your office. Where each product's data goes is set out in the table above.
Notes and documents are open Markdown, kept on your device, in your own iCloud, in Obsidian or on your company's box. If you ever stop using us, your files are still there and still open.
Today one person records meetings with Lugji; tomorrow Lugoffice produces the formal documents; later the whole company uses Lugbox to find what was said. Same format throughout — no migration.
Start with one person and one phone. Once you see results, use Lugoffice for formal documents, and only then decide whether you need a company knowledge base. You can stop at any step.
Pilot enquiryLugbox is an AI box that sits in your office, with someone to install it, show you how it works and look after it. We're now recruiting our first pilot organisations in Hong Kong.
A small machine with local AI running inside. The knowledge base and search stay on the machine in your office.
On-site installation, adding your data, showing colleagues how to ask. A real person to talk to, not a support ticket.
Regular checks and updates. Talk about a long-term contract only once you're happy with the pilot — and stop if it doesn't suit you.
Lugbox's knowledge base and query AI run on a machine in your office; storage and search never go through LUGJI servers. Meeting organising uses cloud AI: the text passes through our relay server in Hong Kong (the relay stores no content) to Google Vertex AI; under Google's enterprise terms, your data isn't used to train AI models.
Common questions about Lugji, Lugoffice and Lugbox — each one tagged with the product it's about.
Yes. It uses Apple's built-in speech recognition, running entirely on your device. Cantonese is the main focus for now.
They aren't uploaded to any Lugji server or sent to cloud AI. By default they're stored on your device and in your own iCloud, and you can choose iPhone-only storage. Transcription happens on your device, with no account needed.
No. Notes can stay on your iPhone only, or in your own iCloud. If you want a second brain, connect Obsidian and notes go straight into your vault — no plugin needed.
iOS 26 or later. Transcription needs iPhone 12 / SE (3rd generation) or later; on iPad, iPad (10th generation) / Air (4th generation) / mini (6th generation) or later. AI summaries are a Beta feature and need an Apple Intelligence model (iPhone 15 Pro or later).
Lugji is currently free to download and use, with no in-app purchases and no account needed.
Lugji captures what was said; Lugoffice turns it into documents. They're separate apps. In Lugji, tap “Send to Lugoffice (cloud AI)” to tag a meeting; in Lugoffice, choose your Lugji folder once. A document is only generated when you then pick a tagged meeting in Lugoffice. Only the text is sent — the audio recording never is.
Lugoffice never sends your recordings. Only the text you choose is sent to cloud AI to generate documents, and under Google Cloud enterprise terms it isn't used to train models. We don't store your content.
Yes. Paste in your meeting notes, dictation or drafts and get the same documents. For pasted text, Lugoffice asks for your consent before every generation.
Lugoffice is currently free to download and use, with no in-app purchases or subscriptions. It works on iPhone and iPad with iOS 18 or later.
Lugbox is still at the pilot stage and has no public pricing. To find out about the pilot, fill in our enquiry form or email sales@lugji.app.
