Your Inbox, On Autopilot. Every Decision, On Record.
An enterprise email intelligence platform built around a proprietary AI engine — designed, built, and owned entirely by Zetaton. It intercepts inbound email, runs multi-signal AI classification, routes every message to the right inbox and person, and logs every decision with full reasoning. Zero-touch triage with complete auditability.
Hi — we were billed twice this month and finance needs this resolved before end of day. This is really urgent, please escalate.
The AI assigns 9 signals, a routing rule fires, and the email drops into the right inbox — replay any time.
“Most AI email tools are thin wrappers around someone else’s model — opaque, unauditable, impossible to tune.
Cortax AI needed async idempotent classification at production scale, deterministic routing that satisfies compliance, multi-tenant isolation enforced at the database layer, and encrypted OAuth credential storage — without AI latency blocking the user-facing API.
Zetaton built the Cortax AI Engine from scratch as a standalone FastAPI microservice — independently containerized, versioned separately, secured with HMAC-SHA256.
Standalone FastAPI service designed first — HMAC auth, message-ID idempotency, and the routing trace schema finalized upfront.
PostgreSQL RLS from the first migration, indexed tenant_id, a withTenant() wrapper, Supabase + PgBouncer tuned for Cloud Run.
Async pipeline + priority rules + Gmail (OAuth2) and Outlook (MSAL + Graph webhooks). OAuth tokens AES-256-GCM encrypted at rest.
Operator interface for virtual inboxes, routing rules, and ticket queues — with AI signals visible on every ticket.
Every capability reachable via API key, with full Swagger / OpenAPI documentation.
Each slot is reserved for a shipped product screenshot — reference it by its ID to drop the real image in.
A standalone FastAPI service gives full control over models, prompts, schemas, and cost — no vendor lock-in.
9 signals per email via Groq LLMs, message-ID idempotency, and suggested reply drafting.
Voyage AI embeddings → pgvector, hybrid retrieval, reranking, LLM grading, and source citations.
Immutable records, fully replayable weeks or months later — compliance from day one.
We design, build, and ship AI products end-to-end — and put them in production with metrics you can point at.
