The tools we use.

The backbone of every AI feature. GPT-5-nano powers the chat, text-embedding-3-small handles knowledge base search, and gpt-realtime-2.1-mini enables the voice assistant. BYOK support lets you use your own API key.

All subscription billing runs through Stripe. Checkout sessions, customer portal, and subscription lifecycle events (created, updated, canceled, payment failed) are handled via webhook.

Property images and uploaded assets are stored in a private S3 bucket. Guests access images via presigned URLs with a 1-hour TTL. Uploads can be done client-side (presigned) or server-side (multipart).

Sign-in is exclusively via Google OAuth, handled by Auth.js v5. No passwords are stored. On first sign-in, an organization and owner account are created automatically.

All application data — organizations, users, properties, knowledge base sections, guest sessions, messages, and requests — is stored in MongoDB via Mongoose. Multi-tenancy is enforced at the query layer.
