In your group, admins can find out who's behind a message without leaving the chat: reply to it with /lookup and Lookup shows the card of whoever wrote it, even if they have no username.
Add Lookup to your group
- Open @doublegram_lookup_bot and tap ➕ Add to a group.
- Pick your group. Lookup joins already as an admin: it needs no permissions, only to be an admin, so it can see the messages.
If Lookup is in the group but isn't an admin, /lookup and the alerts don't work: tap 🔑 Make Lookup admin under its welcome message.
The group's Premium
/lookup and the group alerts are part of Premium. The group gets it from one admin with Doublegram Premium:
- whoever adds Lookup to the group, or makes it admin;
- or whoever taps 💎 Activate Premium here in
/settings.
Only the admin who gave it can take it back, with 💎 Release the group's Premium.
How to use /lookup
- Reply to a message with
/lookup: you get the card of whoever wrote it. - Or write
/lookupfollowed by a username, an ID or a t.me link.
The card shows the ID, username, name, type of account and Telegram's warnings, such as scam or fake accounts.
Only admins can use it, and not as an anonymous admin: write with your own account. Searches made with /lookup don't count toward your personal daily searches.
Invisible or visible to everyone
From /settings → /lookup command you choose how the card shows up:
- Invisible (default): only the admin who asked sees the card, and the command doesn't show up in the group either.
- Visible to everyone: the card is sent to the group as a normal message.
Settings
Admins open the settings with /settings in the group, or with ⚙️ Settings under the welcome message. There you find the /lookup command, the two alerts and, in ⚙️ More settings, 🔐 Who can change the settings: all admins or only the owner.
The flags under the welcome message change Lookup's language in the group.
Your members can also search from the group itself: 🔍 Search here starts a search from any chat, with their own searches.
