Tool Information
NL Pearl provides AI voice and text agents for customer support, lead handling, appointment workflows, and sales conversations.
Businesses connect approved knowledge and channels, configure identity and escalation, test calls and messages, obtain consent where required, and monitor transcripts, actions, and outcomes.
Paid access starts from $19 per month; agents, voice minutes, messages, numbers, integrations, and support vary.
Agents can misstate policies, record sensitive speech, or contact people without valid consent. Disclosure, permissions, accurate knowledge, call laws, and human handoff are required.
