Anonymous Q&A in class or at work
Let people ask the awkward question without putting their name to it. Open a room, share the link, and close it when the session is over.
(01)Anonymous group chat
Say it once.Then let it burn.
Nullchat is group chat with no accounts and no history. Open a room, share a link, and when it's over it's gone for everyone.

here's how it works ↓
(02)How it works

Open a room.
One tap. No email, no phone number, no password. Pick a throwaway name and you're in.

02
Pass the stub.
Share the room link, or tear off a one-time stub for each person. Once it's used, it's dead, even if someone copied it.
Room link

for Priya, only.
This stub opens the room once.

Watch it burn.
Turn on burn mode and messages turn to ash for everyone. Close the room and the messages and files go with it.

(04)Features
Small features.
Zero residue.
Everything a group chat needs, and nothing that outlives it. No profile to fill in, no archive to clean up, no settings buried three menus deep.
- 01Anonymous namesA temporary name that lasts for the session and disappears when you leave.
- 02Burn modeEvery message turns to sand after the time you choose, for everyone in the room.
- 03One-time linksGive each person a link that works once. Forwarded or copied, it's already dead.
- 04Room passwordsPut a password on top of the link for rooms that need a second lock.
- 05Member limitsCap the room at any size, or make it invite-only.
- 06Images up to 25MBShare pictures freely. They're deleted when the room ends.
- 07Voice messagesRecord and send voice notes without leaving the chat.
- 08Live pollsSingle or multiple choice, with results landing in real time.
- 09Replies & mentionsReply to a message or mention someone so busy rooms stay readable.
(05)Use cases
For conversations that shouldn't stick around.
Use case 02 / 04
A private backchannel for events
Give a talk, a meetup or a game night its own chat that exists only for the event. Set a timer and the room closes itself.
Use case 03 / 04
Plans that shouldn't stick around
Sort out a surprise, a trip or a sensitive group decision, then let burn mode turn the messages to sand.
Use case 04 / 04
Feedback and tips, without a trail
Hand out one-time links so each person gets in once. No accounts, no phone numbers, and nothing stored afterwards.
(06)Try it
Every voice is a node.
None are recorded.
Type a message and watch it join the mesh. Then refresh the page. It's gone, just like a real room.

(07)The receipt
Most apps keep everything.
We print zeros.
No phone number to sign up, no profile tied to who you are, no archive waiting on a server. When a room closes, this is the whole bill.
