AI Agent Architecture
Orchestration layer
Each portal has its own agent router. The user's message hits an SSE stream endpoint that feeds the Anthropic API with a system prompt scoped to that portal's capabilities and the user's memory context.
Tool pipeline
48 tools defined as JSON Schema function signatures. Claude selects and calls tools in sequence, streaming text + tool_use blocks back to the client. Tools execute server-side, results streamed as they complete.
Memory system
Persistent per-user memory stored in Supabase (`ai_memory` table). Recalled on every session via a `memory_recalled` action. Covers preferences, past actions, and context the user has shared with the AI.
Takeover mode

The user types “Let AI take over.” The agent enters a loop — it uses tools to navigate to pages, fill forms, send messages, and update records, streaming every action live. Built without a third-party agent framework; the loop is native Next.js Server-Sent Events + Anthropic streaming.

What others haven't built.

1
Four-portal unified memory
A single Supabase backend serves four distinct portals — secretary (native title), member (self-service), individual (personal AI), and business (operations). Each portal has its own auth layer and RLS policies but shares AI memory and action history. No competitor has this breadth across one platform.
2
Streaming agent takeover
The AI can navigate the application UI on behalf of the user in real time — filling forms, sending comms, updating records — while streaming every step to the screen. Built on tool_use streaming, not a wrapper around a third-party agent framework.
3
AI action log with hours-saved attribution
Every AI action is logged with a calibrated time-saved estimate (e.g. form_filled = 45 min, meeting_minutes = 60 min). This gives users a live 'hours recovered' metric and gives investors a defensible engagement KPI that no competitor tracks.
4
Partnership white-label infrastructure
NTRBs, accounting firms, and business associations can sign up as partners, set their own branding (logo, colours, support email), and invite their client organisations via tokenised 7-day invite links — all within the platform. Partners earn a seat-based network effect.
5
Native title-specific AI tools
COA letter generation, ILUA plain-English summarisation, ORIC/CATSI Act compliance tracking, and member eligibility management are bespoke tools not offered by any general-purpose AI platform. This vertical specificity is the core PBC moat.
