Advanced Chat Applications

Build complete chat experiences that remember context, call tools, and stream answers with a professional UI. Whether standalone or embedded in your existing applications, Pika provides everything needed for production chat applications.

Chat Application

Advanced Chat Applications provide full-featured conversational interfaces backed by AI agents. Each chat app is independently configured with its own agents, tools, access controls, and feature settings, all hosted on a shared platform infrastructure.

Building a production-quality chat application requires far more than a demo prototype. You need session persistence, streaming responses, error handling, access controls, and professional UI polish. Pika provides all of this out of the box, letting you focus on agent intelligence rather than infrastructure.

Host one or many chat applications with fine-grained control over access:

  • Internal-only apps for employees
  • External-only apps for customers
  • Shared apps accessible to both audiences
  • Per-app feature configuration
  • Independent agent and tool assignments

Multiple Chat Apps

Conversations persist across turns and sessions:

  • Users resume where they left off
  • Full conversation history maintained
  • Automatic or manual title generation
  • Session search and organization
  • Pinning for quick access

Agents can call typed tools to access data and take actions:

  • Tool inputs and outputs conform to schemas
  • Reliable, explainable tool invocation
  • Multiple tools per agent
  • Shared tool library across agents
  • Real-time tool execution

Professional interface that works everywhere:

  • Streaming responses render as they arrive
  • Syntax highlighting for code blocks

Provide 24/7 support with AI agents that access customer data:

  • Look up orders and account information
  • Answer product questions
  • Process refunds and returns
  • Escalate to human agents when needed

Chat apps are defined declaratively through configuration:

const chatAppConfig: ChatAppConfig = {
chatAppId: 'customer-support',
chatAppName: 'Customer Support',
shortDescription: '24/7 customer assistance',
agentIds: ['support-agent'],
chatAppUserTypes: ['external-user'],
enabled: true
};

Customize features for each chat app:

  • Enable/disable file uploads
  • Control trace visibility
  • Configure suggestion prompts
  • Set response verification thresholds
  • Customize UI elements

Multiple levels of access control:

  1. User Type - Internal vs external users
  2. Entity - Organization/account boundaries
  3. Role - Admin, power user, standard user
  4. User ID - Specific user access grants
  5. Chat App Level - Enabled/disabled state

Create secure sharing links:

  • Time-limited access
  • Read-only or interactive mode
  • Respect entity boundaries
  • Track shared session usage
  • Revoke access when needed

Advanced Chat Applications are designed for production scale:

  • Streaming latency - First tokens in <2 seconds
  • Session loading - Recent messages load instantly
  • History search - Full-text search across all sessions
  • Concurrent users - Scales automatically with AWS infrastructure
  • File handling - Supports uploads up to configured limits
