Google Antigravity, AI Studio, Workspace Flows, Vertex AI & BigQuery AI

Every growing business eventually hits the edge of standard office buttons: you need an AI to watch an inbox, parse a 20-page PDF engineering spec, check live stock in Xero or SQL, and alert a manager in Google Chat. This is the specialist tier where Maintain AI builds production systems that run themselves.

The expert Google AI builder stack

Google Antigravity (Agentic Software Engineering IDE)

Google’s flagship agent-first development platform where autonomous coding agents plan, write, test, verify, and deploy full-stack business software and integrations under senior engineering supervision — cutting custom build timelines from months to days.

Google AI Studio & Gemini API (Structured Extraction)

Direct API access to Gemini Pro and Flash with strict JSON schema enforcement and 1M+ token context windows. Extracts line items, GST, and PO numbers from 500 PDF supplier invoices per month for cents.

Google Workspace Flows & Apps Script (Zero Middlemen)

Event-driven automation across Forms, Sheets, Gmail, Drive, Docs, and Chat with built-in Gemini reasoning steps — replacing $500+/mo brittle Zapier chains natively inside your Google account.

Vertex AI Search & Looker / BigQuery AI

Indexes tens of thousands of company files with strict per-user Drive ACL permissions, while BigQuery AI lets directors query millions of rows of financial and margin data in plain English.

Real-world New Zealand business examples

Trades & Civil Contracting

85-staff civil & utilities contractor (Waikato & Auckland)

Bottleneck: Subcontractor dockets and daily plant sheets arrived in 15 formats, costing 3 admin staff 40+ hours/week to reconcile against job codes.

Workflow: Built a Gemini API + Cloud Run pipeline in Antigravity that ingests photographed dockets, enforces a strict JSON schema, validates job codes against BigQuery, and flags exceptions in Google Chat.

Outcome: Cut docket reconciliation from 40 hours/week to 3 hours of exception review.

Professional Services

40-staff legal & patent advisory firm (Wellington)

Bottleneck: Needed firm-wide search across 60,000 historical matter files where junior staff could never see restricted partner or M&A folders.

Workflow: Deployed Gemini Enterprise / Vertex AI Search with native Drive ACL inheritance so every answer strictly respects the logged-in user’s folder permissions.

Outcome: Instant precedent retrieval with 100% partner permission compliance.

Wholesale & Distribution

110-staff national industrial distributor

Bottleneck: Paying $1,800/month for brittle third-party SaaS connectors that silently broke whenever a supplier changed an invoice PDF layout.

Workflow: Replaced the entire chain with native Workspace Flows, Apps Script, and a self-healing Cloud Run worker monitored 24/7 by Maintain AI.

Outcome: Cut monthly software fees by 85% with 99.98% pipeline uptime.

Use Google Workspace Flows or a Gemini-assisted Apps Script macro inside Sheets to automate a recurring weekly report.

Maintain AI production build

Complete production architecture built in Antigravity and deployed inside your own Google Cloud / Workspace tenant.
Automated integration tests, schema validation, error alerting, rollback blueprints, and full client ownership of code.
Optional NZ$950/mo Maintain tier for 24/7 autonomous SRE monitoring and self-healing.

When it is the wrong tool: If your workflow is a simple 2-step notification used twice a month, do not pay for a custom Cloud Run build — use a native Workspace rule or spreadsheet macro instead. We tell you this upfront at the free assessment.
