  • Predictable per-seat pricing: No per-conversation markup on WhatsApp.
  • 10-minute setup: vs Respond.io\'s 3-6 hours.

The AI-first vs workflow-first distinction

Respond.io\'s AI executes workflows you configure. You define decision trees, and the AI runs them. Great control, real setup effort.

OT1-Pro\'s AI reads customer intent and picks the response path on the fly. Less manual configuration; the AI handles off-script messages gracefully. Better for teams that want AI to genuinely help rather than execute predefined scripts.

Migration path

Respond.io-to-OT1-Pro migration takes 1-2 weeks. Export contacts + conversation data as CSV, rebuild flows in OT1-Pro (AI simplifies this), run parallel for 2 weeks, cutover. See our migration playbook.

Choose Respond.io if

  • You need LINE, WeChat, or KakaoTalk integration.
  • You\'re on an enterprise contract already delivering value.
  • Your primary customers speak English or Southeast Asian languages.

Choose OT1-Pro if

  • Your customers speak Arabic natively.
  • You want AI-first unified inbox architecture, not add-on workflow AI.
  • WhatsApp + Instagram + Facebook are your primary channels.
  • Per-conversation pricing is eating your margins.
