Engagement

How we roll it out

A 5-step process from kickoff to handover. Every step has a deliverable you can sign off on.

  1. 01

    Source inventory

    Audit which docs to index and who can see them.

  2. 02

    Pipeline build

    Parse → chunk → embed → store, with versioning.

  3. 03

    Query interface

    Web app or Slack bot with citation rendering.

  4. 04

    Permissions + audit

    SSO, per-doc ACLs, full query log.

  5. 05

    Continuous ingest

    Webhook-driven re-indexing as content changes.

Outcomes

What you can expect

Real numbers we see when Document AI & RAG Knowledge Base ships on top of an actual workflow. Specifics vary with starting baseline, data quality, and scope — but these are the ranges.

Outcome 01

−85%

Lookup time

From minutes searching to seconds answering with citation.

Outcome 02

92-97%

Answer accuracy

Against ground-truth Q&A set, tuned over 6-8 weeks.

Outcome 03

10K+ docs

Source coverage

Per workspace, with permissioning and version awareness.

Sample use cases

What this looks like in practice

Three concrete scenarios where teams deploy Document AI & RAG Knowledge Base today. Your engagement starts with one of these (or your own variant) and expands from there.

01

Onboarding new hires in 1 week

Engineers ask the bot anything about the codebase, runbooks, or product — answers cite the exact doc + line. Ramp time drops from 3 weeks to under 1.

02

Legal due-diligence acceleration

A counsel team uploads 200+ contracts. The agent surfaces non-standard clauses, missing indemnities, expiry windows — saves 60+ hours per quarter.

03

Cross-team policy clarity

HR + Finance answer 'can I do X?' questions from the workforce automatically, with permission-aware retrieval — sensitive policies stay private.

Typical engagement
