Build a Custom AI Agent for Customer Support
You create an AI agent to handle routine customer service inquiries by connecting a large language model to your knowledge base. This allows it to use that context to answer questions automatically via email or a chat widget.
Syntora offers expertise in building AI customer service agents that integrate with existing data sources. They design systems with intelligent routing, drawing on experience with multi-agent platforms for document processing and workflow automation.
The scope of such a system depends significantly on your existing data sources. An agent trained solely on a structured FAQ database is typically more direct to implement. However, if the agent needs to query live product databases, order history systems, or a CRM like HubSpot, it requires more complex API integrations and specialized logic to retrieve and interpret dynamic information. Syntora's approach focuses on understanding these data requirements early to define an effective architecture.
What Problem Does This Solve?
Many teams try off-the-shelf chatbots from platforms like Intercom or Drift. These are great for routing but fail at contextual understanding. Their visual builders create rigid decision trees. If a customer asks, "Can I change my address if my order was placed 2 hours ago?" the bot sees "shipping address" and offers a generic FAQ link, failing to check the actual order time in Shopify.
Newer "Build your own GPT" tools can ingest a PDF, but they have no connection to live data. They can answer "What are your policies?" but cannot answer "Where is order #ABC-123?". This forces them to escalate any query that requires specific customer data, defeating the purpose of automation and creating more work for the human team.
A 12-person SaaS company faces this when a customer asks, "My invoice from last month seems high, can you explain this charge?" A chatbot trained on public help docs cannot access billing data in Stripe. It replies with a useless link to "Understanding Your Invoice", frustrating the customer and creating a manual ticket. The core failure is the inability to securely access and interpret live, private data.
How Would Syntora Approach This?
Syntora would approach your customer service automation by first conducting a discovery phase to map your most common routine inquiry types and identify relevant data sources. This includes evaluating existing systems like product catalogs in Supabase or order history via APIs such as Shopify. We would then design an architecture that uses the Claude API's extensive context window to provide rich, contextual prompts based on the full customer conversation and knowledge base articles.
The core logic layer would be developed in Python, leveraging a framework like FastAPI. For example, addressing an inquiry like "Where is my order?" would involve the FastAPI service making targeted API calls to your existing order management system to retrieve real-time status. This information, along with the order number and customer's original question, would then be passed to the Claude API to generate a natural language response. This approach aligns with our experience building multi-agent platforms using FastAPI and Claude tool_use for internal operations. Logs would be structured using tools like structlog to support efficient debugging and system monitoring.
Deployment options would be discussed, considering factors like scalability, cost, and existing infrastructure. A common pattern is to deploy FastAPI applications as containerized services on platforms like DigitalOcean App Platform, mirroring our own operational deployments which feature SSE streaming. The system would expose a secure webhook for integration with your chosen front-end chat widget or email parser. Asynchronous HTTP clients like httpx would be used for external API calls, ensuring the system remains responsive.
A critical component of the design would be human-in-the-loop escalation. This would involve developing clear rules for when an AI-generated response requires human review, such as queries involving refunds, complaints, or those where the AI's confidence score falls below a defined threshold. This triage logic would be implemented as part of the application, ensuring that complex or sensitive inquiries are routed appropriately. Our Oden orchestrator, which uses Gemini Flash function-calling to route tasks to specialized agents for document processing, data analysis, and workflow automation with human-in-the-loop escalation, provides a conceptual foundation for such intelligent routing mechanisms in your customer service agent.

Connects to Your Live Data
Pulls real-time order status from Shopify, user data from your Supabase database, or ticket history from Zendesk.
What Does the Process Look Like?
System Discovery (Week 1)
You provide read-only access to your knowledge base and relevant APIs. We deliver a build plan outlining the top 5 inquiry types to be automated.
Agent Logic Development (Week 2)
We write the core logic in Python and connect to your systems. You receive a private staging link to test its responses.
Integration and Go-Live (Week 3)
We connect the system to your customer-facing channel (email, chat). We deliver documentation for your team on how it works.
Monitoring and Handoff (Weeks 4-6)
We monitor performance and escalation rates for 2 weeks post-launch. You receive a final runbook and full source code access.
Frequently Asked Questions
- How is the cost and timeline determined for an AI agent?
- Cost is based on the number and complexity of data sources. An agent answering questions from a single FAQ document is a 2-week build. One that needs to query a live order database and a CRM might take 4 weeks. We provide a fixed-price quote after a 30-minute discovery call where we map out these connections.
- What happens if our product database API goes down?
- The system is built with fallback logic. If it cannot connect to a live data source like your Shopify store, it will respond, 'I'm currently unable to access live order information, but a team member will get back to you shortly.' It then automatically creates a ticket in your help desk with an alert about the API failure.
- How is this different from a platform like Ada or Forethought?
- Platforms like Ada are priced for larger teams and often involve per-resolution pricing which can be unpredictable. Syntora builds a system using direct API calls to foundational models like Claude. This approach is simpler, has lower operating costs (just API and hosting fees), and gives you full ownership of the underlying code.
- How do you handle sensitive customer data?
- We never store PII. The system processes data in-memory during a request and logs are anonymized. For systems like CRMs, we use read-only API keys that are stored in a secure location like AWS Secrets Manager. The agent is deployed within your own cloud infrastructure, giving you full control over the data environment.
- How is the agent updated when our products or policies change?
- The system reads directly from your existing knowledge base, like a Notion page or a folder of Google Docs. To update its knowledge, you simply edit the source documents. There is no separate 'training' process required. For changes to API logic, we handle that as part of the optional monthly maintenance plan.
- Can the agent handle multiple languages?
- Yes. The underlying Claude 3 Sonnet model is fluent in many languages. The same Python code can handle inquiries in Spanish, French, or German by changing a parameter in the prompt sent to the API. We can configure it to auto-detect the incoming language and respond appropriately, typically without adding significant time to the build.
