ATCL AI Assistant
Built end to end
01The system
A bilingual voice-and-chat consultant that is the front of house for a Saudi ICT company.
On atcl.nzum.space the assistant greets visitors in English or Arabic, answers only from a curated knowledge base about ATCL’s infrastructure, AI, software, cybersecurity and managed services, hands over brochures, and captures callback requests as leads — by text, or by voice with barge-in.
02What I did
Designed and built it end to end: the persona and guardrails, the tool calls for document hand-over and lead capture, server-owned consent, the cost guards, and the ecosystem “constellation” view it lives in.
03How I built it
Measured before deciding. Spoken Saudi phone numbers transcribe correctly only a third of the time, so a lead is confirmed by read-back or a typed field rather than trusted. The faster speech model won on real reply lengths by about 830 ms per turn, so it is the one in use. Greetings are pre-rendered, so an idle visitor costs nothing. Four guards close the open-microphone tap: thirty seconds of silence, a switched tab, twenty-five turns, and daily caps. Sixty-five tests, each one written from something that actually broke.
