Case study: Human-reviewed AI document workflows

PT Stratcon Agara Global (SAG) Corporate Development Intern (2026) · Strategic Technical Advisor

How I built AI tools that read operational documents while keeping a person responsible for every record that matters. A two-minute read.

  • Apps Script / Gemini
  • Python / Flask
  • Google Cloud Run
  • AppSheet

The problem

Operational documents, including government permits, lived in shared folders. Turning them into searchable records by hand is slow, and letting an AI fill those records alone is too risky when they carry legal consequences. The goal was faster retrieval without giving up human accountability.

The approach

AI does the reading; people make the decisions. The system extracts metadata, flags anything it is unsure of, and a reviewer approves it before it becomes a record anyone relies on. Questions are answered from those approved records or from the source files, with a citation back to the document. Google Groups and Shared Drives set who owns and can read each department’s files.

Architecture: source documents feed an AI extraction step; a human reviews uncertain fields before records are approved; staff query approved records through a dashboard and a chat assistant that cites its sources.
System architecture, simplified. No company data is shown.

Built versus deployed

Component Status
Permit metadata extraction (Apps Script + Gemini 2.0 Flash) with human verification and AppSheet review views Built; production deployment was pending when the internship ended in March 2026
Cited document Q&A over Google Drive (Vertex AI Search) Prototyped
Document-status assistant (Python/Flask on Cloud Run, via WhatsApp) Designed and presented; live use not verified
Versioned document-control and readiness tracking (Cloudflare Workers + D1) Implemented and locally tested; production acceptance not yet confirmed
Checklist-compliance checker for import/export and environmental (AMDAL) requirements In trials; not yet used by real users
Meeting-transcription pipeline (Whisper) Built

There is no measured time-saving baseline yet, so this page makes no efficiency claims. The work was presented to company leadership on 2 March 2026.

My contribution

I built the permit-extraction workflow with its human-review step and AppSheet views, prototyped the cited Q&A, and designed the document-status assistant during my internship (January to March 2026). As Strategic Technical Advisor from August to October 2026, I specified and implemented the document-control system and took the compliance checker to trials.

Lessons

  • Review is a design feature, not a fallback. Deciding which fields need a person shapes the whole data model.
  • Show the source. An answer that links back to its document is easier to check than one that only sounds confident.
  • Meet people where they already work. The tools ran in a dashboard and a chat channel rather than a new application.
  • Access control is part of the architecture. Ownership of the shared drives had to be settled before any AI could read them.

Company documents, client names, and identifiers are deliberately left out. The document-control system and other internal tools are described in Compliance Document Control & Internal Tools.
