Sellio Sellio is an AI customer-support platform that unifies live chat, WhatsApp, Instagram, Telegram and email into one shared inbox. Teams train AI agents on their own knowledge base, docs and FAQs so the agents can answer first-line questions automatically. A free plan includes the inbox, chat widget and channels; paid plans add more seats, AI conversations and analytics. The product is priced per workspace rather than per agent and is aimed at small support teams of 2–20 people.
