Built for Engineers, by Engineers
Three tools, one workflow. Search your engineering documents with cited answers, build calculators that replace your spreadsheets, and produce reports on your letterhead.
Jump to
Search your engineering library
Upload your engineering documents and search across all of them with cited answers linked to the exact page.
Search across every document with cited answers linked to the page
Search your personal documents, organisation libraries, and shared resources in one place. Every result links back to the exact page so you can verify the source and cite it with confidence.
Get instant answers from your engineering tables — like steel sections and material properties
Engineering reference tables — like geometric steel sections — live natively in Fontana's database. Ask things like "what's the difference between the heaviest 180UB and the lightest 200UB?" and the agent pulls the exact values, reasons over them, and gives you a sourced answer.
Inspect every referenced source with a relevance score for each page chunk
Every answer comes with a referenced sources table showing the relevance score for each page chunk used in the summary. Open any source directly to verify the quality of the citation.
Your Excel spreadsheets, elevated
Drag in your existing spreadsheets or build new calcs from scratch. Every feature below is built into every calculator.
Drop your existing Excel calcs in — get extra features not extra work
Import your existing Excel calculations with a single click. Fontana automatically converts them into clean, interactive calculators with revision history, sensitivity analysis, printable calc sheets and more.
Pass/fail checks and live sensitivity analysis on every input
Every calc can include pass/fail status and interactive sliders that show exactly how outputs respond to changing inputs. Explore the design space and verify decisions before they ship.
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.
Outputs from one calc feed straight into the next
Chain calculations into pipelines. Outputs from one step automatically become inputs to the next, so a full design sequence runs end-to-end without manual handoffs.
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.
Reports that write themselves
Build a template once — from scratch or from an existing Word document — and every project report after that is fill, sign, print.
Print-ready reports on your firm's letterhead
Every report renders with your organisation's letterhead and logo, drops in signatures from your signature library, and prints straight to PDF — the finished deliverable, not a draft to reformat.
Attach a datasheet, get a structured section back
Drop in a product datasheet and ask Fontana to pull what you need — "list the installation conditions as a table under headers" — and it reads the document, reasons over it, and builds the section for you.
Upload an existing Word doc — fields detected automatically
Bring the templates you already use. Upload a DOCX and Fontana converts it into a reusable report template, detecting the fill-in regions for you — names, dates, addresses, job numbers.
