NU CRON uses AI to schedule the right message on the right channel at the right time. Orchestrate SMS, email, voice and WhatsApp journeys with AI-powered auto-replies, conversion analytics, and CRM integration — all from one canvas.
The flow
01 · TRIGGER
An event, signup, or schedule drops a contact into the journey.
02 · SEGMENT
Rules and traits split contacts into the right branch and channel.
03 · SCHEDULE
Send-time optimised per contact from behaviour and timezone.
04 · SEND
Delivered over SMS, email, voice or WhatsApp; replies handled by our AI.
05 · MEASURE
Opens, replies, and conversions tracked across every channel.

Drag-and-drop journeys
Build branching journeys across every channel on one canvas, then watch contacts flow through in real time. A/B test variants, let AI pick winners, and retire underperformers automatically.
Capabilities
NU CRON orchestrates on top of the NU rails — our journey engine, send-time models, and a self-hosted, tuned suite of local models drive SMS, voice, and messaging delivery directly, so campaigns run end to end without stitching tools together.
