Intercom Fin
Customer support agent that resolves tickets with your help centre.
Agents
Developer platform for chat and voice agents with visual flow building.
Botpress targets developers building assistants that ship — visual flows plus code, knowledge engines, and deployment to WhatsApp, web and voice channels. The free tier is genuinely usable.
TypeScript extensibility sets it apart from pure no-code tools. Usage-based pricing above the free tier.
