Group Butler

Group Butler has been managing Telegram groups since the platform's early bot era, and its own profile leads with exactly this subtopic's two concerns: showing the group rules or description on command, plus welcome-related features, before mentioning anti-flood and custom triggers. It is a more established, if less actively marketed, option than newer welcome-only bots.

As with several long-running bots in this space, treat its scale claims with some caution since there is no public monthly-user counter — verify it responds reliably in your own group before relying on it as your only rules-and-welcome tool.
