The calc package you stitch together from a patchwork of disconnected tools — in one document. Unit-aware math, code-referenced templates, interactive charts, and a vector-PDF binder, all live-linked.

Every engineer has wasted hours stitching these tools together — and re-stitching them after every revision. EngCanvas folds the whole packet into one document.
A finished calc package gets stitched together from a half-dozen apps — Excel for the math, code-clause lookups, a CAD detail, Bluebeam to bind it. Every handoff is a chance for a number to drift out of sync.
You convert kip to lb, ft to in, and psi to ksi by hand — hoping you didn't drop a factor of 1000. Unit and conversion errors have sunk real engineering projects. Your calculator doesn't catch them.
You revise one input, but the Word write-up, the CAD detail, and the Bluebeam markup still show the old numbers. Re-syncing by hand is slow — and skipping it is how wrong dimensions ship.
From formula to stamped PDF without switching tools. Every clip below is the real app, recorded.
Type formulas with real units
Write engineering expressions the way you think. Assign variables, reference cells, and use 190+ built-in functions. Units are first-class — type '25 ft' and the system tracks dimensions automatically.
Instant results with unit validation
Every formula evaluates in real-time with full dimensional analysis. The engine catches unit mismatches before they become design errors. Cross-reference between sheets, VLOOKUP the built-in AISC shape database, and goal-seek to target values.
Export PE-ready PDF reports
Your calculations are already documented. Arrange them visually on the report canvas, add headings and notes, then export a professional PDF with your company header, PE stamp area, and page numbers — no reformatting step.
Drop in your existing .xlsx calculator. EngCanvas keeps your formulas and cell references intact, then lets you tag cells with real units. From that moment every downstream formula is unit-aware — and dimensional mistakes get caught instead of shipped.
The import covers formulas, references, named ranges and cell formatting. Macros, pivot tables and conditional formatting don't come across — you'll see a report of anything that was skipped.
Start from a code-referenced template rather than a blank page: one insert brings the calculation, its input bands, the live schematics and the drawing tabs.

Not another generic spreadsheet. Every feature was designed for engineering calculation workflows.
100+ engineering units with automatic dimensional analysis. Multiply force by distance and get moment. Divide load by area and get stress. The engine tracks Length, Mass, Time, and Force dimensions through every operation — and catches mismatches before they become design errors.
Supports compound units: kip/ft, lb/in², ft·kip, pcf, and more
A full spreadsheet with 190+ functions — SUM, VLOOKUP, IF, LINTERP, and engineering-specific functions like REBAR and CONC_FC. Cross-sheet references, named ranges, freeze panes, and formula highlighting. Everything you need from Excel, with units built in.
Cross-sheet references, named ranges, and Excel .xlsx import/export
Drag calculation boxes, tables, charts, and notes onto an infinite canvas. Arrange your work spatially — group related calculations, add headings, embed live charts. Every box evaluates live and renders beautiful LaTeX notation. It's a digital engineering notepad.
22 interactive chart families via ECharts — used for P-M interaction, V/M shear-moment, and pressure diagrams
Export to true vector PDFs — selectable text, crisp KaTeX math, vector drawings, and small files (charts embed as high-resolution images). The Report Binder assembles a cover, table of contents, index, reports, sheets, and drawings — in any order — into a single PDF with continuous page numbering. Your calculations go straight from screen to the reviewer's desk.
Single vector-PDF binder — cover, TOC, index, and continuous page numbers across every section
Paste one URL into Claude, ChatGPT, Grok or Microsoft Copilot Studio and it can work on your actual EngCanvas projects — reading them, changing them, checking them and exporting the PDF. Not a copy pasted into a chat window. The real thing.
Included with every paid plan. Tokens bill to your own assistant subscription, not to EngCanvas.
I'm an EIT structural designer, and I kept rebuilding the same calculation packages in Excel and Word — hidden formulas, units tracked by hand, and hours lost reformatting before anything could be reviewed. I wanted to write calcs the way I actually think, with real units, and get a clean report in one step. So I built EngCanvas.
It's brand new — you'd be one of the first to use it. Try it, and tell me what's missing.

Everything you need to know about EngCanvas.
EngCanvas is a paid product, but you start with a 7-day free trial. A card is required to begin, you won't be charged during the trial, and you can cancel anytime before it ends. After the trial it's $49/mo for a single user — a founder rate locked through the end of 2027 if you start now.
Yes. EngCanvas can import .xlsx files with automatic formula conversion. Your cell references, named ranges, and common functions (SUM, VLOOKUP, IF, etc.) are preserved. Units aren't part of standard Excel, so you'll add those as you work — but the import gives you a head start.
The math engine works for any discipline that uses unit-aware calculations — its 100+ built-in units cover force, stress, length, moment and pressure alongside thermal, fluid and electrical quantities. The shipped template library is structural today: beam and column design, concrete, masonry, wood, steel connections and foundations, referenced to ACI 318, AISC 360, TMS 402, NDS and ASCE 7. If you work outside structural, you get the engine and the spreadsheet — you'll build your own templates rather than starting from ours.
Calculations run client-side in your browser, and your projects sync to the cloud so they're backed up and available across devices. Projects are stored in a managed Postgres database (Neon) that encrypts data at rest and in transit as standard. We don't sell your engineering data or share it with third parties.
Yes. The PDF export includes customizable company headers and footers, a professional cover page with project details, automatic table of contents, page numbering, and a designated PE stamp/seal area — so you can produce calculation packages formatted for plan review. You apply your own seal: EngCanvas formats the deliverable, it doesn't provide certification.
Every value carries dimensional metadata tracking Length, Mass, Time, and Force. When you write '50 kip / (12 in × 18 in)', the engine automatically computes the result in ksi (kip/in²). If you accidentally try to add force to length (e.g., '5 kip + 10 ft'), the engine will flag the dimensional mismatch immediately — before it becomes a design error.
Yes. EngCanvas publishes your projects to an AI assistant over the Model Context Protocol (MCP). One URL — copied from the MCP tab in the app's right panel — connects Claude, ChatGPT, Grok or Microsoft Copilot Studio, and from there the assistant works on your real projects: reading calculations, editing them, reporting which design checks fail, goal-seeking to a target, and assembling the report PDF. It can't delete a project. The connector is included with every paid plan, and tokens are billed to your own assistant subscription rather than marked up through us.
All calculations are performed client-side in your browser using our JavaScript math engine — results update instantly with no server round-trips. You'll sign in to access the app and to sync your projects to the cloud.
