Beyond the shared inbox: agents that finish the job
Respond.io, Wati, and SleekFlow are good at putting your team in one inbox across messaging channels. Kontakt starts from a different job: an AI agent that answers, follows up when your systems spot a drop-off, takes the payment, and logs what it completed, with your team stepping in only when needed.
Inbox vs agent
A shared inbox scales human replies. It does not scale finished work: recovering signups at 2am, running renewal windows for thousands of policyholders, or proving which campaign produced a funded account. Kontakt gives you the inbox when a human is needed, and an agent for everything else, on every channel, not just messaging apps.

| Proof of work | Messages handled, response time | Jobs completed: signups, payments, saves |
| Revenue attribution | Limited | Tracked links tie outcomes to the conversation |
| Compliance | Varies | Supervised review, auth tiers, audit trail per AI turn |
| Channels | WhatsApp-centric inbox | Web, SMS, email, WhatsApp, Instagram, USSD, in-app |

Choose an inbox tool if
Your team handles most replies manually, volume is manageable, and you mainly need routing and broadcast capability on WhatsApp.
Choose Kontakt if
You need AI that resolves tier-1, outbound recovery, attribution, or compliance controls, and you want one platform across web chat, SMS, and email as well as messaging apps.
