Enterprise-grade security, built in

Your customer conversations are sensitive. Opsei protects them with the controls large enterprises expect, so you can put AI on the front line with confidence.

Access & audit control

Role-based access, single sign-on (SSO), and per-user audit logs so you always know who saw and did what.

Encryption everywhere

TLS 1.3 encryption in transit and AES-256 encryption at rest for every conversation, record, and file.

SOC 2 Type II

SOC 2 Type II controls with independent annual audits covering security, availability, and confidentiality.

Data residency

Tenant-isolated data that is never used to train third-party models, with US-based data residency available on enterprise plans.

Integrations

Works with the tools you already use

Opsei plugs into your stack two ways: Automated Workflows push new leads, customers, and tickets out to your other apps the moment they happen, and Live Answers let the AI look up real information from your systems mid-conversation.

Automated Workflows (outbound)

Fire secure webhooks on every new lead, customer, ticket, or ended conversation. Connect to your CRM, back office, or thousands of apps through Zapier, Make, and n8n. Every delivery is logged, retried, and testable.

Live Answers (inbound connectors)

Let the AI query your own HTTPS APIs while it is talking to a customer - order status, bookings, account details, a customer's plan - and reply with the live result on both chat and voice.

FAQs

AI Receptionist questions, answered

What is an Opsei AI receptionist?
It is an AI voice agent that answers your business phone, holds a natural conversation with the caller, and takes action, answering questions, qualifying the lead, booking an appointment, transferring the call, or taking a message, then logs everything to your CRM.
Will it actually sound human?
Yes. Opsei uses a natural streaming voice with real-time turn-taking, so callers can interrupt and speak normally. Most callers simply experience a helpful, responsive receptionist.
Can it book appointments and transfer calls?
Both. It can check availability and book live during the call, and it can warm-transfer urgent or VIP callers to the right person based on the routing rules you define.
How does it know about my business?
It answers from your shared knowledge based on your website, PDFs, FAQs, and other documents, and can look up live information from your own systems mid-call using inbound connectors.
How long does setup take?
Most businesses are live in under an hour. Connect a number, add your knowledge base, set your greeting and rules, and switch it on.
