Is there a free WhatsApp group bot?

Yes. Banter's Free plan is $0 and covers one WhatsApp group with 100 AI replies a month — no card required to start.

Free includes the bot's personalities, memory, commands and keyword reactions on a fast Haiku-class AI model. When a Free workspace reaches its monthly reply limit, the bot posts one notice in the group and resumes the next month, or you can upgrade any time.

Starter ($9/month) raises the limit to 1,000 replies across 3 groups, and Pro ($25/month) goes further with custom personalities, AI image generation and bring-your-own API keys. See pricing for the full comparison.
