Temporary groups built around a topic
Start a conversation about something you care about or join an open room anonymously — no account or permanent profile required.
Create or join
Choose a short conversation topic and Hallo creates a temporary room. Other adults can discover it and join with an anonymous guest identity.
Groups allow up to 12 people, expire after two hours, and disappear as soon as everyone leaves. Messages are live and are not restored for later visitors.
Safer group conversations
- Age confirmation and house-rule acceptance are required
- Topics and messages pass through automated text moderation
- Message and room creation limits reduce spam
- Leave any group instantly
Common questions
Do I need an account?
No. Hallo uses a temporary anonymous session and a guest name for the group.
How long do groups last?
At most two hours. Empty groups disappear immediately.
