Don't just search your
engineering library.
Build from it.
Find any answer across your team's PDFs, spreadsheets, and references — with citations. Then turn what you found into an interactive calculator anyone can re-use.

“Pipelines is an incredibly intuitive tool for stringing together calculations into a seamless workflow. It has the potential to massively speed up tedious and repetitive calculations.”

“Fontana took my Excel spreadsheets and turned them into professional engineering calc sheets I can trust — versioned, consistent, and impossible to accidentally break.”

From documents to interactive tools, in three steps
Upload
Add your team's engineering documents — PDFs, spreadsheets, references. Fontana indexes everything for natural-language search with citations.
Build
Search to find the answer with citations. Generate an interactive calculator from what you find — or import an existing Excel calc.
Share
Every calc is versioned, auditable, and shared with your team. One library, one source of truth — searchable forever.
What every Fontana calc comes with
Whether you generated it from a search result, imported from Excel, or built it from scratch — every calc has these built in.
No need to click and check Excel cells — every formula is visible, tabulated and editable
Every calc in Fontana is fully transparent. All formulas are visible, colour-coded and editable in a tabular format — no more clicking through your coworkers Excel cells to find the one formula you need to change.
Get instant answers to your engineering questions — without leaving your calc
Don't waste time dusting off that old engineering textbook or digging through PDF after PDF. Just ask Fontana's built-in Copilot any question — whether it's 'what's the formula for axial buckling?' or 'what's the yield strength of mild steel?' — and get an instant answer, right in your calc.
Steel sections, material data, and reference tables — built in
Link engineering reference data directly into your calcs. Steel section properties, material data, capacity tables — select from a dropdown and every dependent formula recalculates instantly.
Calc sheets that look like the engineering reports your team already uses
Fontana renders every calculation as a clean, printable calc sheet — formatted like the engineering reports your team already submits and reviews. The output feels familiar, not foreign.
See exactly what changed, when, and by whom
Every change to a calc is tracked. Roll back any edit with a click, see who modified what, and answer the 'why is this number different from last week?' question in seconds.
More ways into Fontana
Search-and-generate is the fastest path. These are the others — for teams with an existing Excel library, or building a calc from nothing.
Bring your Excel library
Already have a library of Excel calcs? Drag them in. Fontana converts each spreadsheet into a versioned, interactive calculator — formulas preserved, no rewrite needed.
