· Inboxi Team
Inboxi, Intercom, Zendesk AI, Tidio, Chatbase, Manychat, Wati, SleekFlow, Trengo and Kommo compared for teams handling high-volume WhatsApp, Instagram and email conversations.
Customer support has changed shape. The question is no longer whether an AI agent can answer a question, but whether it can answer it in the channel the customer already uses, with the customer's own order in front of it, and hand over cleanly when it should not answer at all.
We compared ten platforms on the things that decide the outcome for a support team: channel coverage, how the agent is trained, which actions it can take without a human, the quality of the handover, and the real monthly cost at 2,000 conversations.
The short version: platforms built around a single chat widget struggle the moment your customers show up on WhatsApp or Instagram, and platforms built around a shared inbox struggle to let the agent actually do anything. The teams getting the best results use a tool that treats the inbox and the agent as one system.
How we compared them
We compared the platforms on what each company publishes about its own product: the channels it supports, how its agent is trained, the actions it can take inside a chat, how it hands a conversation to a person, and its listed prices. Features and prices change often, so check each vendor's own site before you decide.
An agent that answers ten things perfectly earns more trust than one that answers a hundred things loosely.
What separated the leaders
Three things: whether the agent could see the customer's actual order, whether it could take an action (refund, reschedule, send a payment link) without leaving the chat, and how the handover looked from the human's side, full context or a cold ticket.
Below you will find each platform's strengths, its gaps, and who it is the right choice for.
