Build Any Engineering
Calculator in Seconds
Describe what you need, and Fontana builds it — interactive sliders, sensitivity charts, and professional CalcSheets. No coding required.
Trusted by award winning engineering consultancies and leading Australian suppliers
See It in Action
Every calculator below is interactive. Drag the sliders, change the section, and watch everything update in real-time.
Interactive Calculators
Create calculators with sliders, dropdowns, and computed results. The AI tool generator builds them from your formulas — no coding required.
Simply Supported Beam — Deflection
Deflection at center of simply supported beam with central point load
Sensitivity Analysis
Swap input variables and see how nonlinear relationships affect your results. Build engineering intuition through rapid iteration.
Sensitivity Analysis
δ vs Point Load (kN) (UC: 200 UC 59.5, L = 4 m)
CalcSheets
Turn calculations into professional reports with live values, compliance checks, and {{placeholder}} syntax. Every CalcSheet is a living document your team can interact with.

More Than Just Calculators
Fontana gives your engineering tools a knowledge base, an AI assistant, and a document processing pipeline to back them up.
AI Tool Generator
Describe what you want to calculate, and Fontana generates a working tool with inputs, formulas, and outputs. Wind load calculators, deflection checks, thermal analysis — anything you can describe.
Knowledge Base Search
Upload your engineering documents and search them with natural language. Fontana finds the exact clause, table, or formula you need across your entire library.
AI Chat Agent
Ask questions about your documents and get answers with source citations. Your AI assistant can search, calculate, and reason across your entire knowledge base.
Document Processing
Upload PDFs and our OCR pipeline extracts text, chunks content intelligently, and indexes everything for instant retrieval. Upload once, search forever.
How It Works
From idea to professional calculation report in three steps
Describe
Tell Fontana what you want to calculate. Describe your formula, your inputs, and what you need to see — in plain English.
Create
Fontana generates an interactive calculator with sliders, dropdowns, and live results. Add sensitivity analysis to see how inputs affect your outputs.
Document
Turn your calculation into a professional CalcSheet with live values, compliance checks, and shareable reports. Every CalcSheet updates when you change inputs.
