Personal Virtual Assistant
Replies on WhatsApp in the owner's own voice and Cantonese style, 24/7
An AI digital twin that answers WhatsApp messages the way the owner would, in their tone and Hong Kong Cantonese style. Contacts get a fast, personal first reply even when the owner is in meetings or travelling.
What it does01
- Replies to one-to-one chats, for everyone or only an approved contact list
- In groups, speaks only when someone tags the owner or replies to one of their messages
- Transcribes voice notes, understands them and answers
- Reads and describes photos before replying
- Searches the news live and answers with the source and date
- Sends meeting reminders to a group and follows up when nobody has replied
- Stays silent on stickers, videos, documents, status updates and broadcasts

Ad-hoc AI vs our agent workflow04
The same task, done by prompting a general chatbot by hand versus through the agent’s set workflow.
Tokens per task
Right first time
- Persona and chat history pasted in for every message
- Replies sound generic and need rewriting into Cantonese
- Voice notes must be typed out by hand first
Tokens per task
Right first time
- A fixed persona file sets tone, limits and topics
- Group rules decide when to stay silent
- News answers carry a live source and date
No AI is 100% reliable. When a run fails, the agent retries automatically or hands it to a person.

How it works06
- Step 1
A WhatsApp message arrives
- Step 2
It sorts the message: text, voice note, photo or other
- Step 3
Voice is transcribed and photos are read; others get no reply
- Step 4
Persona and tone rules shape the reply
- Step 5
News questions trigger a live search with sources
- Step 6
The reply goes out on WhatsApp as the owner
Why it's trustworthy07
- A written persona file sets the tone, boundaries and topics it may cover
- Group behaviour follows fixed rules, not guesswork
- News answers always say where the information came from and when
Good for08
- Founders and consultants with busy WhatsApp inboxes
- Trainers and coaches who get the same questions every day
- Sales teams that want fast first replies without losing the personal touch
