ChatNBX

Maintains real-time conversation state and message history across web, mobile, and desktop clients through a centralized message store with device-agnostic session management. Uses WebSocket connections for live updates and local caching layers to ensure seamless context switching when users move between devices without losing conversation position, unread markers, or draft messages. The architecture appears to employ a conflict-resolution strategy for concurrent edits and a unified notification queue to prevent duplicate alerts across devices.

Analyzes incoming customer messages and conversation history using a language model to generate contextually-relevant response suggestions that support agents can accept, edit, or reject. The system appears to use conversation embeddings and message classification to determine suggestion relevance, with a feedback loop that allows agents to rate suggestion quality. Suggestions are generated asynchronously to avoid blocking the agent UI, and the model likely fine-tuned or prompted with domain-specific support patterns to reduce generic outputs.

Allows support agents to add internal notes or comments to conversations visible only to team members, enabling collaboration on complex issues without exposing internal discussion to customers. Internal notes are likely stored separately from customer-facing messages, with different access controls and visibility rules. The system may support @mentions to notify specific team members of internal notes, creating a collaboration workflow within the conversation context.

Provides a single interface for managing both internal team conversations and external customer support threads, routing messages to appropriate channels based on conversation type (internal vs. customer-facing) and participant roles. The system likely uses role-based access control (RBAC) to determine visibility and permissions, with separate message queues or channel partitions for team vs. customer conversations. Internal team discussions can reference or escalate to customer conversations without exposing internal context to customers.

Delivers messages to intended recipients with low latency using a pub-sub or message queue architecture (likely Redis or similar), with intelligent notification routing that respects user preferences, device state, and do-not-disturb settings. The system batches notifications to prevent alert fatigue, deduplicates across devices, and likely uses exponential backoff for delivery retries. Notifications are routed to appropriate channels (push, email, in-app) based on user configuration and message priority.

Indexes all messages and conversation metadata using full-text search (likely Elasticsearch or similar) to enable fast retrieval of past conversations by keyword, participant, date range, or conversation status. The search likely supports boolean operators and filters, with results ranked by relevance and recency. Indexing happens asynchronously to avoid blocking message ingestion, and the system maintains separate indices for team vs. customer conversations to respect access control during search.

Tracks agent online/offline status, current availability (available, busy, away, do-not-disturb), and presence indicators visible to team members and potentially customers. The system likely uses heartbeat pings or WebSocket keep-alives to detect disconnections, with automatic status transitions based on inactivity timeouts. Presence data is broadcast to relevant clients in real-time, enabling intelligent conversation routing to available agents and preventing customers from waiting for unavailable support staff.

Manages assignment of conversations to individual agents or teams, with escalation rules that automatically route conversations to higher-tier support or management when specific conditions are met (e.g., unresolved after 24 hours, customer sentiment negative, issue complexity high). The system likely uses a rules engine to evaluate escalation conditions, with audit trails showing assignment history. Escalations may trigger notifications and update conversation priority or SLA timers.

Allows agents to tag conversations with custom labels (e.g., 'billing', 'bug', 'feature-request', 'urgent') and add structured metadata (customer type, product, issue category) to enable filtering, reporting, and knowledge organization. Tags are likely stored as denormalized fields in the conversation record, enabling fast filtering and aggregation. The system may support tag suggestions based on conversation content or previous tags, reducing manual annotation burden.

Enables export of conversation history in standard formats (CSV, JSON, PDF) for compliance, auditing, or knowledge base building purposes. The system likely supports bulk export with filtering by date range, participant, or tags, with options to include or exclude internal team messages. Exports may be asynchronous (queued and emailed) to avoid blocking the UI, and likely include metadata (timestamps, participants, assignment history) alongside message text.

Displays customer conversation history and context when an agent opens a conversation, including previous interactions, customer profile information, and relevant metadata (account status, purchase history if integrated). The system likely queries a customer database or CRM integration to populate context, with caching to reduce latency. Context is displayed in a sidebar or panel adjacent to the current conversation, enabling agents to understand customer history without leaving the chat interface.
