Confidently design, deploy and monitor voice AI in production

Everything you need to effectively design, test, operate and monitor your voice AI agents. So you can focus on what makes your experience unique.

Get all the essentials you need

Easily monitor performance and opportunities

Stellar's monitoring dashboards simplify monitoring AI agent performance, and allow auditing and replaying individual agent conversations to drill down on potential issues.

We can also integrate with your existing Contact Center and Customer Experience Platform stack to surface relevant Stellar metrics and conversation details in your existing customer service applications.

Prefer access to Stellar's metrics via your own internal systems and BI stack? We will set it up.

Transfer to your human agents where needed

Stellar provides granular control over when to transfer to a human agent, for example for specific topics, customers, or circumstances. Even for situations where you prefer a human agent to handle the request, Stellar can already automate some of the boring stuff. This includes authenticating the user or determining the correct customer service team to transfer to based on the user request.

Teach the AI agent your knowledge and processes

Reliable retrieval of external knowledge in agentic AI is hard. We see companies making costly mistakes figuring this out in-house, resulting in poor AI agent performance, high operational costs, and longer time-to-production. 

We've learned the hard way how to effectively teach AI agents the knowledge required to reliably act as phone support agents. Rely on our learnings, and let Stellar optimise your internal documentation for AI agent processing for you.

We can work with knowledge stored in different formats, including PDFs, databases, websites and your internal knowledge management system. Your data is stored using enterprise-grade data practices, and never used to train the underlying AI models.

How it works

Take action in your systems

Stellar's agents can be securely integrated with your systems of record, to take action and retrieve data on behalf of your customers. Whether that's in your CRM, ticketing system, commerce store, or a custom-built system.

Integrations are restricted to pre-approved actions and workflows, and Stellar's out-of-the-box guardrails help shield against unwanted action and access in your systems. Common actions include:

Price Icon

Interact with ticketing system, to open new tickets or inform customers about the status of an ongoing ticket

Price Icon

Identify and authenticate customers before sharing personal info or taking actions, via integration with (often a combination of) the APIs of SaaS, COTS and/or custom-built systems

Price Icon

Help customers with common account-related issues, such as password resets or (re)sending certain information via email

Reliable guardrail management

Guarding your AI agents against unwanted situations which could put your company or customer experience at risk is Stellar's guardrail system. We run a separate set of AI models on top of our main conversational AI model, to evaluate interactions against enabled guardrails and adjust or even cut off conversations if needed.

‍Stellar agents come built-in with a set of safety guardrails for common customer service scenarios, so you don't have to implement these yourself.

On top of these, we will help you identify and configure your business-specific guardrails. These include which topics are considered off-limits, or which types of customers to automatically redirect to your human agents.

Multilingual support

Stellar uses a combination of multiple AI models, which support over 50 different languages. Our agents have access to any of these languages during conversations with a customer, and can switch to a customer's preferred language if you've enabled the language in your agent's configuration.

Auditing & call analysis made simple

Stellar automatically creates call transcripts, conversation summaries and call recordings, which are made easily accessible via the Stellar Studio. As part of Stellar's insights, potential problem areas that may require further investigation are automatically surfaced in the monitoring dashboard.

Your data is stored using enterprise-grade data policies and never used to train the underlying AI models

Icon

Multilingual support

Icon

Enterprise-grade security

Stellar is built with enterprise-grade security, data privacy and compliance at its core. Besides comprehensive monitoring, audit trails and data policies, our product comes with a set of built-in safety mechanisms to protect AI agents against common attack vectors. Your data is not used to train the underlying AI models.
