Capabilities
Everything your chat agent needs to resolve requests end-to-end.
Stellar's AI chat agents don’t just answer questions — they can take action in your systems on behalf of your customers and dynamically look up specific information in your systems during a conversation. This lets them effectively handle even complex requests end-to-end without human intervention. Where needed, the agent can seamlessly hand off the conversation to your team with full context on the request and what was already discussed, so your representatives can pick up right where the AI left off.
Real-time knowledge retrieval
Dynamically retrieve relevant knowledge from your docs as needed during conversations, or connect the agent to your existing helpdesk or knowledge management system so it can search for answers in real-time.
50+ languages, zero setup
Offer multilingual support out-of-the-box across 50+ languages. Lock support to specific languages if needed.
Powerful guardrails for safe interactions
Stellar’s Guardrails system evaluates every turn of the conversation based on a combination of built-in rules and rules specific to your context. Powered by a fully isolated secondary AI model that acts as LLM-as-a-judge, any rule violation is immediately flagged and acted upon — whether to escalate to a human, end the conversation, or nudge the agent to steer in a different direction. Rely on Stellar’s battle-tested guardrail library for common customer service scenarios, and let our team help you configure custom rules tailored to your business.
Seamless collaboration between AI and human agents
Warm hand-off to human agents for requests marked out-of-scope for your AI agent or whenever customers ask for human assistance. Summary of what was discussed along with a full conversation transcript are presented upon handover, so your team can pick up exactly where the AI agent left off.

FAQ
Frequently asked questions
What can a Stellar chat agent actually do?
Stellar chat agents go beyond answering questions. They can take actions in your systems — update orders, verify identity, process returns, schedule appointments, send emails and text messages — and resolve customer requests end-to-end without human intervention.
How does the chat agent access our knowledge base?
Stellar can connect to your existing helpdesk or knowledge management system. The Stellar platform can integrate via a range of pre-built connectors, and if needed our team can build custom integrations for your specific system. Alternatively, you can add and manage knowledge documents directly inside the Stellar Studio.
Can the chat agent connect to our existing systems?
Yes. Stellar integrates with your CRM, ticketing system, and internal APIs out of the box. The agent can look up customer data, trigger workflows, and write back to your systems mid-conversation. See our integrations page for a full overview of supported platforms and connectors.
What happens when the agent can't resolve a request?
The agent seamlessly hands off the conversation to a human agent that has access to a conversation summary and full conversation transcript — so your team never starts from scratch.
How do I control what the agent can and can't do?
You can configure the exact topics the agent should handle, and the exact topics and scenarios for which you want to hand off to your team. Stellar has developed a number of proprietary guardrails for common scenarios where you might prefer a human agent to take over. Besides this, Stellar’s guardrail system lets you define your own boundaries, off-limit topics, and escalation triggers.
What languages does the chat agent support?
Stellar’s platform uses a combination of multiple AI models, which support over 50 different languages. Stellar’s AI agents have access to any of these languages and can automatically detect and respond in your customer’s language with consistent quality. The full list of currently supported languages is: Afrikaans, Arabic, Armenian, Azerbaijani, Belarusian, Bosnian, Bulgarian, Catalan, Chinese, Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, Galician, German, Greek, Hebrew, Hindi, Hungarian, Icelandic, Indonesian, Italian, Japanese, Kannada, Kazakh, Korean, Latvian, Lithuanian, Macedonian, Malay, Marathi, Maori, Nepali, Norwegian, Persian, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Swahili, Swedish, Tagalog, Tamil, Thai, Turkish, Ukrainian, Urdu, Vietnamese, and Welsh.
How long does it take to go live?
Most customers have the first version of their agent live within weeks. If preferred our team can provide white-glove support to speed up your go-live, from initial agent design through integration and launch.
Is my data secure?
Stellar is ISO 27001 certified, GDPR compliant, with EU data residency agreements and zero data retention agreements with our LLM providers. Your data is never used to train underlying AI models.
