Haze Guide Haze bot: readings, answers and alerts in your chat
Find @hazeday_bot in Telegram and share your location. It replies with the current 1-hour PM2.5, weather and advice for each situation, and alerts you when the reading crosses your cut-off.
Add the bot
On a phone the button opens Telegram; tap Start. On a computer, scan the QR code with Telegram on your phone.
Get started
- Tap the button above (or search @hazeday_bot in Telegram) and press Start.
- Share your location, or send /place sg to pick a city.
- Send /cutoff 110 to set your cut-off (the value your team or school uses).
- Send /subscribe to turn alerts on.
- Any time, send /now or just ask a question.
What it can do

Using it in a group
You can add @hazeday_bot to a parents' or team group. In a group, use commands with the bot's name, for example /now@hazeday_bot.
Note: the place, cut-off and alerts you set in a group belong to the whole group. Alerts are posted in the group and anyone in it can change the settings. If you only want alerts for yourself, chat with the bot privately.
A WhatsApp version is being prepared and is not open yet. It will be announced here and works the same way (no slash needed: send now, place sg and so on).
FAQ
Does the bot cost anything?
No. It is free and has no ads.
Is the data official?
Singapore readings come from NEA's official data. Other places use a model estimate, and the reply says it is not official.
Can I trust the AI answers?
The AI answers only from the live data and NEA guidance we give it, but it can still be wrong. It is not a doctor; see a doctor if you feel unwell, and follow your school or league's own decision.
How do I stop alerts?
Send /unsubscribe.
Privacy
- To send alerts the bot stores your chat id, chosen place (rounded to about 1 km if you share a location), cut-off, language and alert switch.
- Questions you type are sent to a third-party AI model to produce the answer; we do not store the text. Please do not include personal information in your questions.
- Send /unsubscribe at any time to stop alerts.
