Six flows.One trade.Zero copy-paste.
Cantaia modules aren't tabs that ignore each other. Each flow triggers the next. The email creates the task, the tender creates the schedule, the portal feeds the reports.

Plan registry
PLANS · AI ANALYSIS · AUTO VERSIONING
A plan arrives by email. Cantaia detects it, downloads it, files it by project and discipline. Claude Vision reads the title block, legend, scale. When a revision arrives, it files itself as a new version.
- —Dropbox "Plans" folder with no convention
- —Searching "which plan is the latest version"
- —Emails with 12 PDF attachments
Auto email detection
Pre-filter by extension and keywords. Real plans are saved, false attachments ignored.
Title block analysis
Plan number, title, scale, format, design office, discipline. Extracted in 4 seconds by Claude Vision.
Automatic versioning
When a plan with the same number arrives, a new version is created. The old one moves to archive. Inter-version comparison possible.

Foreman Portal
DAILY REPORTS · PIN · MOBILE-FIRST

- —WhatsApp to send photos of notes
- —Excel entry by the back office on Monday morning
6-digit PIN auth
Rate limiting: 5 attempts / 15 min. 7-day JWT cookie. Zero friction for the team leader, zero accounts to manage for you.
4 mobile tabs
Site · Tender · Plans · Report. Bottom navigation like a native app. Works on 3G.
Photos + handwritten notes
Native camera capture. Canvas API compression. Claude Vision transcribes paper handwritten notes into usable text.

- 05Site Reports centralisation
One flow triggers the next.
Modules aren't isolated. They chain like a real construction site: the tender precedes the schedule, the schedule drives the meeting minutes, the minutes surface in the inbox.
An urgent email generates a task on the project → the task shows up in the next meeting minute → the minute triggers a mail notification to the team leader. Never retyped.
An awarded tender becomes a Gantt schedule. Durations are calibrated on your past sites. CFC dependencies are applied automatically.
The team leader enters hours on the PIN portal. Data flows up in real time into the Reports view. Excel export for accounting, PDF for archives.
A flow starts
