Ark

Multi-Tenant Architecture

Ark’s multi-tenant architecture is built from the ground up to support platforms managing multiple customer domains. Unlike traditional email APIs, which are designed for single-sender use, Ark allows for easy integration and management of numerous customer accounts, ensuring isolation and security for each client.

AI-Readable Documentation

With purpose-built documentation written in AI-readable Markdown, Ark enables developers to cut down on token usage by 10x. This makes the integration process faster and more efficient, allowing AI tools to generate the necessary code without extensive manual input.

Auto-DNS Configuration

Ark simplifies the domain setup process by automatically detecting a customer's DNS provider and guiding them through the configuration steps. This feature eliminates the need for customer support involvement, allowing for a smooth onboarding experience that can be completed in just minutes.

Real-Time Analytics and Logs

Ark provides detailed analytics and logs for each customer domain, allowing developers to monitor email performance and troubleshoot issues effectively. This feature ensures that developers have all the necessary information to address customer inquiries swiftly, enhancing overall user satisfaction.

Clarity

Agentic Customer Service

This feature provides smart, automated AI support that delivers accurate, context-aware answers to customer inquiries. It is designed to follow your specific business rules and brand guidelines, ensuring every interaction is compliant and on-message. By handling a high volume of routine questions instantly, it reduces wait times, improves customer happiness, and allows human agents to focus on more complex, high-value issues.

AI Agents with Human Oversight

Clarity's AI Agents suggest precise responses drawn directly from your company's knowledge base, empowering your support team to reply with confidence and consistency. Crucially, it incorporates a human-in-the-loop model, where agents can review, edit, and provide continuous feedback on AI suggestions. This feedback loop trains the AI in real-time, improving its accuracy and ensuring humans remain in ultimate control of the customer conversation.

Unified Voice of Customer Intelligence

This capability consolidates customer feedback from every channel—including support tickets, surveys, social media, and reviews—into a single, searchable platform. Advanced NLP models automatically analyze this data to spot emerging themes, track sentiment trends, and generate actionable alerts. It eliminates manual tagging, providing product, support, and leadership teams with a unified source of truth to drive data-backed decisions.

Enterprise-Grade Security & Guardrails

Security and reliability are foundational. Clarity is built with robust encryption, role-based access controls, and comprehensive audit logs. It meets stringent compliance standards like SOC 2, GDPR, and HIPAA. The platform includes specialized AI safety guardrails (SASM) that limit automation scope, require approvals for sensitive actions, and actively prevent hallucinations or off-brand replies, ensuring safe and trustworthy AI interactions.

This auto-resolves a significant portion of routine tickets, drastically reducing resolution time and operational costs while freeing human agents to handle escalations and complex problem-solving.

Closing the Customer Feedback Loop

Teams use the unified Voice of Customer intelligence to systematically analyze feedback, identify the root cause of recurring complaints, and track sentiment. This allows them to prioritize product fixes and feature updates based on real customer data, then demonstrate back to customers that their feedback leads to tangible improvements, building greater loyalty and trust.

Empowering and Scaling Support Teams

With Agent Assist, new and existing support staff get real-time, AI-suggested answers and guidance during live chats or calls. This reduces training time, ensures consistent and accurate responses across the team, and boosts agent confidence and productivity, enabling them to handle more complex interactions effectively.

Ensuring Compliant, Multi-Channel Global Support

For global brands, Clarity provides a secure, single platform to manage customer interactions across multiple languages and channels (email, chat, social). Its built-in guardrails and compliance frameworks ensure all automated and human-driven responses adhere to regional data privacy laws (like PDPL) and strict internal brand policies, mitigating risk.

Clarity FAQ

How secure is Clarity?

Security is built into everything we do. We use guardrails, applied AI research, and trust frameworks to keep responses safe and reliable. We are SOC 2 compliant, meet GDPR and regional standards like PDPL, and encrypt data in transit and at rest. Access is role-based, fully logged, and always reviewable.

How do you stop hallucinations or off-brand replies?

We employ a multi-layered approach. Our AI is rigorously trained on your specific knowledge base to ground its responses in fact. Built-in safety guardrails (SASM) define strict limits on what the AI can do autonomously, often requiring human approval for sensitive actions. The continuous human-in-the-loop feedback further trains the AI and corrects any inaccuracies in real-time.

Can humans stay in control?

Absolutely. Human oversight is a core principle of Clarity. Agents have full control to review, edit, or completely override any AI-suggested response. The platform is designed to augment human teams, not replace them. All AI actions are logged, and you can set approval workflows to ensure a human reviews certain types of interactions before they are sent.

How do agents work across languages and channels?
