For engineering teams, and the directors and owners who sign off on their work
Engineering software that lives inside Word, Excel, PowerPoint, and Outlook.
A 200+ calculator engineering library, controlled documents, guided proposals, and one-click transmittals — built directly into the Microsoft 365 apps your team already has open. No new portal to learn, and no more re-deriving a formula, rebuilding a proposal, or hunting for the right revision from memory.

What comes standard with Digital Workspace
What the status quo actually costs you
None of this shows up on a P&L. All of it shows up in your margin.
This is what running on individual memory instead of a shared system actually looks like, day to day. None of it is hypothetical — it's the version of "normal" most technical firms have simply stopped noticing.
The one engineer who remembers "the real formula" retires, changes firms, or takes a two-week vacation — and the answer walks out the door with them.
A number gets fat-fingered into a rushed, one-off spreadsheet at 6pm, and it makes it all the way into a signed, stamped report before anyone catches it.
Two engineers give the same client two different answers on the same job, because they were each working from a different "final" version of the same master file.
A proposal goes out with last quarter's pricing because someone copy-pasted from an old deck the night before it was due.
A transmittal goes out to the client with the wrong revision attached, because a person attached it from memory instead of the system attaching the right one automatically.
The only real question is whether the next one of these costs you a redo, a client, or a very uncomfortable phone call.
Built for everyone who has to answer for the work
Three different people. Three different reasons this matters.
Nobody buys engineering software for one reason. Here's what each person in the approval chain actually gets out of it.
The Engineer
You didn't spend years earning your license to fight with header formatting or dig through last year's project folder for a formula you know you've used before. Every calculator is cited to the standard it came from — you're not guessing anymore, you're confirming. Every document you open starts from the version of "correct" the firm already agreed on.
The Engineering Director
Right now, "quality" depends on which engineer happened to touch the file. Standardize it once — templates, revision rules, the compliance check — and every engineer on the team ships work that looks and holds up the same way, not just your best one. You stop finding out about a problem in a client meeting.
The Business Owner
Every hour spent reformatting a proposal is an hour that didn't get billed to engineering. Every inconsistent, unreviewed document that ships is sitting in a file somewhere, waiting to become Exhibit A if something goes wrong. This isn't a nice-to-have productivity tool — it's the plumbing your margin and your risk exposure both run through, whether you've priced that in yet or not.
See it in action
One connected workspace. Four different jobs.
Flip through each app below — this is the actual interaction model: a ribbon tab, a task pane, and your engineering standards baked into every screen.
Templates, automatic revision history, and a live compliance score — before anything gets published.
Real formulas and lookup tables across 13 disciplines — insertable straight into the worksheet, cited to the standard they came from.
Pick a presentation type and sections — get a fully branded, structured deck in minutes, not days.
Turn a published report into a correctly formatted client transmittal, with the right revision attached, in one click.
The engineering library
Not a spreadsheet template. A reference library engineers actually trust.
Every formula is cited to the standard it came from. Every lookup table matches the values your senior engineers already check by hand — now on tap in Excel, for the whole team, not just the one person who remembers where the old file is.
From motor full-load current to PID tuning to robot cell reach envelopes — if your team calculates it weekly, it's worth putting where they already work.
The product
One flagship product today. More on the way.
SynthoSoft is a product company, not a one-off build. Digital Workspace is live now; the roadmap alongside it reuses the same document-control engine for adjacent, underserved markets.
Digital Workspace
Four connected Microsoft 365 add-ins for engineering, technical, and industrial organizations: controlled document creation in Word, a 200+ calculator engineering reference library in Excel, a guided presentation & proposal builder in PowerPoint, and document-aware transmittals in Outlook — sharing one brand, one workflow, and one set of standards.
Next products, same engine
Every candidate below reuses the existing document-control, revision-history, and compliance-scoring engine with a new template set. None are available yet — this is an honest look at what we're evaluating, not a shipping date.
EPC & Construction Document Control
Templated deliverables and controlled-copy distribution for engineering-procurement-construction firms.
Healthcare Policy & Compliance
Policy version control and audit-ready export for hospitals and health authorities.
Government Records & Policy Management
The same engine adapted for public-sector records governance and access-to-information response.
Who Digital Workspace is for
Not generic office software. Software shaped like your industry.
Off-the-shelf tools make everyone reformat their work to fit the software. Digital Workspace does the opposite — it's shaped around how engineering and technical organizations already work.
Engineering & Manufacturing
Give engineers instant access to your reference calculators, standards, and lookup tables directly in Excel — and controlled, revision-tracked documents in Word.
Industrial & Field Services
Turn a finished report or inspection package into a correctly formatted client transmittal from Outlook, and build technical proposals in PowerPoint in minutes, not days.
Professional & Technical Services
Consulting, design, and advisory firms get brand-consistent deliverable templates with built-in quality and completeness checks — so every consultant's work looks the same.
Regulated & Compliance-Heavy Operations
Automatic revision history, controlled/uncontrolled copy stamping, and a live compliance dashboard mean nothing ships without the paper trail to prove it.
Getting started
From first call to fully deployed, in four steps.
Digital Workspace already exists — getting your team onto it is an onboarding process, not a development project.
Fit call
A short conversation about which apps your team lives in and where templates, calculations, and approvals slow you down today.
Pilot & template review
We review your house style and standards during onboarding so your cover pages, calculators, and correspondence blocks feel like they were always yours.
Centralized deployment
We deploy through the Microsoft 365 admin center, so the add-ins simply appear in the ribbon for every licensed user — nothing for staff to install.
Support as you grow
Guided onboarding, priority support tiers, and quarterly business reviews on Enterprise plans as your standards evolve.
Why it's built this way
The problem in most engineering teams isn't a missing feature. It's four disconnected habits.
Digital Workspace was designed around a specific, recognizable pattern in engineering and technical organizations — not a generic productivity pitch.
The familiar problem
- Engineers re-derive the same standard calculations by hand, or hunt through old files for the last time someone did it right.
- Every proposal and technical report starts from a blank slide or blank page, with formatting and structure that varies person to person.
- Sending a finished deliverable to a client means manually drafting a cover email and hoping the right revision is attached.
What Digital Workspace does instead
- Document control in Word — templates, automatic revision history, and a live compliance dashboard before anything is published.
- An engineering reference library in Excel with 200+ calculators and lookup tables across 13 disciplines, insertable straight into a worksheet.
- A guided proposal-and-report builder in PowerPoint that assembles a fully branded deck from a chosen type and set of sections.
- A document-aware transmittal tool in Outlook that turns a published report into a correctly formatted client email in one click.
Digital Workspace is a licensed, off-the-shelf product — the same four add-ins for every customer, with your own templates and branding applied during onboarding.
What goes into every build
Capability, not just a pretty task pane.
Your templates, not a generic one
Cover pages, headers, footers, approval pages, and document types built around how your organization already labels and structures work.
Your calculations, always current
Formulas, lookup tables, and reference standards live in the add-in itself, so everyone works from the same version instead of an email attachment.
Guided, not blank-page
Wizards and step-by-step builders mean junior staff produce senior-level, on-brand deliverables from day one.
Auditable by design
Revision history, controlled/uncontrolled copy stamping, and compliance scoring are built in from the start — not bolted on later.
Why trust us with your documents
Small, independent, and deliberately boring about your data.
We'd rather tell you plainly how this works than ask you to take it on faith.
Your documents never leave your tenant
Digital Workspace acts on the Word, Excel, PowerPoint, or Outlook item you already have open, inside your own Microsoft 365 tenant. We don't copy your documents to servers we operate, and we don't keep a database of your document content. See our Privacy Policy for the specifics.
Built by engineers, not just software people
SynthoSoft is a product of SynthoCore Automation Inc., a small Ontario, Canada-based automation engineering company with 20+ years of hands-on PLC, HMI, and SCADA work behind it — not a division of a larger vendor. One product, priced plainly on this page, with no bait-and-switch quote process.
Reference tools, not a replacement for your stamp
Every calculator and template is a productivity aid built to match your own standards — not a substitute for engineering judgment. Final review and sign-off is always yours; we say so directly in our Terms, not just in fine print no one reads.
Built on Microsoft's own Add-in platform
No third-party plugin marketplace and no browser extension with broad permissions — Digital Workspace is built and deployed the way Microsoft documents for enterprise Office Add-ins, including single sign-on via Microsoft Entra.

Questions
Before you ask, here's the short version.
No. Add-ins are deployed centrally through the Microsoft 365 admin center, so they simply appear in the ribbon the next time someone opens the app — nothing to download or install on individual machines.
Usually not — it sits on top of and connects into what you already have, most commonly SharePoint, rather than asking you to move data into a new system.
Nowhere but your own Microsoft 365 tenant. Digital Workspace acts on the document you already have open — for example, applying a template or inserting a calculator result — during your active session. We don't copy your documents to servers we operate, and we don't hold a database of your Word, Excel, PowerPoint, or Outlook content. See our Privacy Policy for the full detail on the limited account and diagnostic information we do collect.
Over 200 calculators, lookup tables, and reference standards across 13 engineering disciplines — electrical, mechanical, robotics, controls, networking, safety, fluid power, and more — built directly into Excel.
Individual: minutes — subscribe, then sign in with your Microsoft account inside the add-in and you're unlocked immediately. No license key, nothing to activate separately. Corporate: usually a few business days — your IT admin buys through Microsoft AppSource, assigns seats in the M365 admin center, and employees are signed in automatically the first time they open the add-in.
Digital Workspace is built on Microsoft's official Office Add-in platform, which requires a Microsoft 365 (subscription) plan for Word, Excel, PowerPoint, and Outlook — on Windows, Mac, or the web. If your organization is still running an older, perpetually-licensed copy of Office (bought outright rather than subscribed), email us before you buy and we'll confirm compatibility.
It's licensed, and access is tied to your Microsoft sign-in rather than a key you have to manage. Individual subscriptions are self-serve, month-to-month or annual, managed through your Paddle customer portal (linked from inside the add-in once you're signed in) — cancel any time. Corporate subscriptions are seat-based, billed on your Microsoft invoice, and assigned by your IT admin in the M365 admin center; no end user ever sees a license key or types anything in. Your documents, templates, and data always stay in your own Microsoft 365 tenant.
For individual subscribers, Paddle automatically retries failed payments (dunning) and emails the billing contact. For corporate customers, Microsoft handles billing and dunning on your regular invoice. Either way, if a subscription ultimately lapses, the add-ins show a clear "renew access" message and stop functioning until it's reactivated — there's no silent data loss, and your documents remain fully yours in your own Microsoft 365 tenant.
