AI Integration

AI That Works Inside WhatsApp

Construction teams run on WhatsApp. We build AI systems that live inside your existing workflow β€” processing photos, voice notes, and PDFs automatically.

The Reality

If You Run a Team on WhatsApp, You Know This Feeling

πŸ”

"Finding that photo takes 20 minutes"

You scroll through 3 WhatsApp groups looking for a photo from last Tuesday's foundation inspection. It's in there somewhere.

πŸ“„

"The spec changed. Nobody saw it."

The engineer updated the lintel schedule. Two contractors already ordered the wrong steel. Nobody caught it in the PDF thread.

πŸŽ™οΈ

"The inspector left a voicemail. Now it's lost."

Important condition mentioned verbally on site. Nobody typed it up. It didn't make it into the project notes. The re-inspection failed.

πŸ“Š

"Nine projects, zero visibility"

You know the work is happening. But you can't tell which site has open permit items, which has pending deliveries, and which has a subcontractor waiting on a decision.

What We Build

Not a SaaS Dashboard. An Embedded System

Every integration we build connects to your WhatsApp groups, processes your files, and responds in your existing chat. No new logins, no dashboards, no software to learn.

πŸ“±

WhatsApp as Your Interface

Your team already uses WhatsApp. Your AI works inside it β€” no new apps, no training, no change management.

🎀

Voice Notes β†’ Structured Data

Site supervisors send voice notes. The system transcribes, extracts action items, and files them automatically.

πŸ“Έ

Photo Intelligence

Every photo sent to the project group gets tagged, described, and indexed. Find any image in seconds with a plain English query.

πŸ“‹

PDF Processing

Permits, specs, delivery notes β€” automatically extracted, summarized, and cross-referenced against your project data.

A Day on Site

How It Changes Your Day

7:15 AM
Site Supervisor
Sends voice note to WhatsApp group: "Concrete pour done. Some cracking near column B4. Inspector coming Friday."
7:15 AM
AI System
Transcribes note. Flags "cracking near column B4" as issue. Creates inspection prep item for Friday. Links to structural drawings.
9:30 AM
Engineer
Sends updated spec PDF to group.
9:30 AM
AI System
Extracts all dimensions and material specs. Compares against previous version. Notifies affected subcontractors of changes.
2:45 PM
Project Manager
Types in WhatsApp: "What open items do we have before Friday's inspection?"
2:45 PM
AI System
Returns list: cracking issue from morning, updated spec acknowledgments pending, access permit expiry.

The Research

7 Models Tested. One Architecture Won.

We benchmarked every major vision model on real construction photos, PDFs, and permit documents before choosing a single model for Cabido Design.

πŸ“·
Bulk Photos

Gemma 3 4B (Local)

71 images/minute Β· $0/image Β· Runs on-premise

β€œGood enough for cataloging. Fast enough to keep up with any job site.”

πŸ“„
Structural PDFs

Gemini 3.1 Flash-Lite (Cloud)

6/6 accuracy on structural specs Β· ~$0.01/page

β€œThe only model that correctly extracted every lintel dimension from engineering drawings.”

πŸ”
Critical Analysis

Claude Opus 4.6 (Cloud, on-demand)

49/50 quality score Β· Used for reports & compliance only

β€œEscalated only when it matters β€” not for every photo.”

⚠️

The finding that changed everything:

Claude Opus 4.6 β€” the highest-quality vision model in the benchmark β€” scored 0/6 on structural specification extraction. It got the table format right but missed every dimension. The wrong steel angle size on a masonry wall isn't a minor error.

Gemini 3.1 Flash-Lite scored 6/6 on the same test.

This is why model selection matters more than model prestige.

The Integration Layer

Built on OpenClaw

The piece that connects AI to your team is the channel. OpenClaw is an open-source orchestration layer β€” we run a customized version that plugs directly into WhatsApp, Slack, Telegram, and the other tools your crew already uses every day.

πŸ“²

Meets Your Team in the Channel

WhatsApp, Telegram, Slack, iMessage, Discord β€” the AI shows up where your crew already talks. No new apps to install.

πŸ”“

Open Source Foundation

OpenClaw is open source. We run a customized fork tuned specifically for construction workflows β€” no vendor lock-in.

βš™οΈ

Wired into Your Existing Tools

Not every operation needs AI. OpenClaw routes the right queries to the right systems β€” field chats, document search, or site alerts.
