What is PATS?
PATS is a messaging platform that runs in your web browser. It needs no app download and no phone number: with a Google account or an email address, open vincent1021210.github.io on any phone, tablet or computer and start chatting.
It is built for people who do not have LINE, cannot install apps, or do not want to share a phone number. Messages, photos, groups and voice or video calls all happen in one web page, and new versions load automatically.
Who is PATS for?
If LINE or a regular chat app does not work for you, PATS is a simple alternative. It is especially useful for:
- People who do not have LINE or prefer not to install any chat app
- Students whose phones cannot install apps, or who only use school computers or tablets
- People without a phone number, or who do not want to share it
- Anyone with low phone storage or an older phone that cannot run new apps
- Family members and older relatives who cannot install apps but can open a web address

How is PATS different from LINE and other chat apps?
The main difference: PATS needs no install and no phone number, it works in the browser. It has no sticker store and focuses on messages and calls.

|---|---|---|
| App install | Not needed, runs in the browser | Download and regular updates |
| Phone number | Not needed | Usually required |
| On a computer | Just open a browser | Usually a separate desktop app |
| Phone storage | Almost none | Grows with chat history |
| Price | Free | Mostly free |
| Sticker store | No | Usually yes |
What are the limitations?
PATS needs an internet connection and both people need an account. Good to know before you start:
- An internet connection is required.
- The other person also needs a PATS account.
- Photos in chats expire after 20 days, so download the important ones.
- No sticker store or social feed; PATS focuses on messages and calls.
- The app interface is currently in Traditional Chinese.
- Some schools or groups require an invite code to sign up.
