Cutting manual policy review by ~80%

DocuSentinel AI turns mountains of incoming requests into instant verdicts — Approved, Denied, or Escalate — backed by precise policy citations and recommended actions. Edge cases go to humans. Everything else clears in seconds.

The problem

Departments in regulated environments receive thousands of daily requests — approvals, access changes, exceptions, procurement. Each requires a human reviewer to read the request, locate the right policy, interpret the rules, and issue a ruling. The bottleneck grows linearly with request volume; the cost grows with headcount; error rates creep up as reviewers get tired.

The team needed an engine that could handle the routine volume without a cloud dependency, without hallucinations, and with a fully auditable decision trail.

Our approach

We built DocuSentinel AI as a document-to-verdict pipeline with three non-negotiable properties:

  • Grounded answers only. The LLM never reasons in isolation. Every verdict cites the specific policy clause it relied on — no citation, no verdict.
  • Triage, not replacement. Clear-cut cases get Approved or Denied automatically. Ambiguous ones get Escalated to a human with a pre-written summary, saving reviewer time even on edge cases.
  • Deployable offline. The whole stack — model weights, vector store, orchestration — can run inside a client’s network with zero external calls.

How it works

  1. Ingestion. Incoming requests (email, ticket, form) are normalized, redacted of PII not needed for the decision, and chunked.
  2. Policy retrieval. Active policy documents are loaded into a local vector index. The relevant clauses for each request are retrieved via hybrid search (BM25 + dense embeddings).
  3. Reasoning. An LLM produces a verdict + citation + recommended action, constrained to a strict output schema.
  4. Verdict routing. Approved/Denied flows auto-complete. Escalate flows route to the appropriate human queue with full context.
  5. Analytics. A dashboard tracks volume, escalation rate, and policy-citation frequency for continuous policy tuning.

Why it mattered

Reviewers went from drowning in routine triage to focusing on the 20% of cases that actually needed judgment. The citation requirement built trust with legal and compliance teams — every decision is defensible on demand, not a black-box ruling.
