Inboxes

Every channel where customers can reach your AI agents. Each one becomes an inbox in Kronos with its own thread list, real-time conversations, and the option to take over from the AI at any time.

Available channels

Open any of these for the per-channel setup guide. You can connect as many inboxes per channel as your plan allows.

Connect WhatsApp via the official WhatsApp Cloud API — pricing, templates, activation, multi-inbox per Kronos account.

Hook up your own Telegram bot as a Kronos inbox. Customer messages land in Kronos and your AI agent replies. Connect as many bots as you want.

Custom Inbox

Connect your own product, app, or automation. Send inbound messages to Kronos and receive agent replies through your webhook.

Voice (Agentic Calls)

Take and place real phone calls with your AI agent. Mexican and US numbers, real-time speech, full transcripts in your inbox.

Activate a Mexican voice number

Step-by-step KYC for Mexican numbers. Persona física (RESICO/PFAE) and persona moral (S.A. de C.V., etc.) — what documents to upload for each.

Activate a voice number (instant)

Instant-activation numbers — no documents, no review. Live in seconds. Currently the only country besides Mexico in this category is the United States.

How inboxes work in Kronos

Every inbox shows the same view: a thread list on the left, the active conversation on the right. Your AI agent replies in real time; you can jump in, take over, or let the AI continue handling things — switching between modes is a single click.

Voice notes, images, PDFs, and other files are surfaced inline where the channel supports them. Read receipts and message status come straight from the underlying platform or your Custom Inbox webhook. Full history is searchable from the unified search bar.

Instagram and Messenger inboxes work the same way — they share the multi-inbox model with WhatsApp. Their setup lives inside the WhatsApp guide for now since they follow the same Meta onboarding flow.

Before you connect Instagram or Messenger

Three prerequisites decide whether your accounts show up in the picker:

You must be an admin of at least one Facebook Page. Connecting works at the Page level, not the personal-profile level.
On Facebook's permission screen you have to tick the Page you want to connect. It is easy to click straight through without selecting one, and the result looks the same as having no Pages at all.
For Instagram, the account must be a professional account (Business or Creator) linked to that Facebook Page. A personal Instagram account cannot be connected.

If the account picker comes up empty, it tells you which of these is missing.

Assigning agents to an inbox

Each inbox has a default AI agent that handles its conversations. You set it during the inbox setup, and you can change it any time from the inbox settings page. One agent can handle multiple inboxes; one inbox has one default agent.

If you want an agent to also use external tools (Gmail, Shopify, etc.) inside a conversation, that is a separate setup — see Integrations.
