Each board has an objective, its own knowledge, and a Calypso Agent bound to it that moves conversations forward column by column. Your team watches the progress on the board and takes control anytime: one switch pauses the agent, any conversation can be taken over and handed back, and everything is traced. ## **About Callbell** Callbell is a customer support and sales platform that brings WhatsApp, Messenger, Instagram, Telegram, and TikTok into one multi-agent inbox, positioned as a WhatsApp CRM with more than 2,000 customers across Latin America. It is priced per agent with channels and modules added on, and offers a bot builder and, on Enterprise, a ChatGPT integration. ## Pricing comparison**Calypso ** Calypso is priced per workspace, not per person. Starter is $19, Pro $49, Scale $199 a month, each with a fixed monthly answer allowance and storage. Extra answers are prepaid at $10 per 1,000, extra teammates $19 a seat. The bill does not move with how many people sit at the board.**Callbell** Callbell is priced per agent: $15 a month on Chat Multiagente, $20 on Plus, custom on Enterprise. Channels are added on top, with WhatsApp from $54 a month in consumable credits and $22 a month for extra accounts, and the broadcast and bot builder modules are paid separately. Costs scale with seats and channels. ## A shared inbox versus Smart Boards**Calypso ** A Smart Board is a plan, not a pile. Each department gets a board with an objective; each column says what must be true before a conversation moves on. New chats land in New, Hidden keeps personal contacts out of reach, and every card shows who is on it and what is unread.**Callbell** Callbell organises work as a multi-agent inbox: conversations from every connected channel arrive in one place, are assigned to agents, and are handled with its chat-management module and tags. It is built around agents replying, with statistics on the Plus plan. ## Bots versus the Calypso Agent**Calypso ** Every board has its own Calypso Agent, included on every plan. It is bound to that board, answers in the voice and guidance you set, follows guardrails, and works each conversation toward the column objective, moving the card when the objective holds. One switch turns it off and your team takes over with full context.**Callbell** Callbell automates with a bot builder module for scripted flows, and offers a ChatGPT integration on its Enterprise plan. Automation is an add-on to the inbox rather than an agent assigned to a pipeline. ## Business knowledge**Calypso ** Calypso Context turns your documents, spreadsheets, websites, and images into the knowledge each board answers from, scoped per board so Sales never quotes the return policy. Every answer carries its source, and your team can see it.**Callbell** Callbell’s automation is flow-based: you write the branches a bot follows. Its pages do not describe answering from uploaded documents or a knowledge base. ## Channels**Calypso ** Calypso is built for WhatsApp first. The same agent, knowledge, and guardrails also run on your website through the widget, and from your own tools through the OpenAI-compatible API, MCP, and n8n.**Callbell** Callbell covers more consumer channels: WhatsApp, Messenger, Instagram, Telegram, TikTok, and live chat in a single inbox, each channel priced as an account. ## Control**Calypso ** A Hidden board that is completely out of bounds, guardrails per board, take over and hand back any conversation, one switch per board, and a trace of every answer, action, and move with its source.**Callbell** Agent assignment and roles in the inbox, with SAML and SSO on the Enterprise plan. ## Developers**Calypso ** An OpenAI-compatible API on every plan, an MCP server for Cursor and Claude Desktop, an n8n community node, and a web widget. Point any client at Calypso and it answers with your business behind it.**Callbell** API and integrations are available from the Plus plan. ## Callbell vs Calypso: which one to choose? ### **Choose Callbell if… **- You need Messenger, Instagram, Telegram, and TikTok in the same inbox as WhatsApp. - You run broadcast campaigns and want them in the same tool. - You want a classic per-agent CRM inbox and are happy to script bot flows. ### **Choose Calypso if… **- WhatsApp is where the work is, and you want conversations moved toward outcomes, not just answered. - You want an AI agent that answers from your own documents and shows its sources, on every plan. - You want predictable per-workspace pricing that does not climb with seats and channels. - You want to stay in control: a Hidden board, guardrails, one switch, and a full trace.**Try the difference**## **Give your WhatsApp somewhere to go.** Create a Smart Board, set the goal and the steps, and let a Calypso Agent move conversations forward.
