Sesame vs Brevian: Which is better?

Sesame is an AI voice companion focused on natural, expressive conversational interactions.

BREVIAN is a no-code platform designed to allow enterprise business users to build custom, secure AI agents. These AI agents understand English, can integrate with team data and applications, answer queries, and automate repeated tasks without requiring a developer. BREVIANs AI agents are used for support teams and security analysts and are implemented with safety and security for enterprise-readiness. For support teams, agents understand data from ticketing systems, CRMs, knowledge bases, and release notes to assist in resolving tickets faster. For security analysts, agents help discover, analyze, and resolve issues faster. BREVIAN agents can understand questions and connect the dots between your data to answer them. They have the capability of performing knowledge extraction for structured and unstructured data, including images, and can answer complex questions with full referenceability and attribution. BREVIAN agents are built with low latency models for PII, PHI, prompt injection, and content moderation filters to redact or modify unsafe responses. They are also easy to manage and use, making them accessible to everyone. They include a menu-driven, no-code interface for building agents, a conversational chat interface for end users, and an API interface for easy integration. The AI agents are fully customizable, permitting business teams to customize agent knowledge, behavior, and security policies based on the use case. BREVIAN aims to automate workflows in the enterprise realm.
