For operations consultants

Leave a working tool.
Keep your method clear.

Turn a repeatable calculation into a branded client tool. Define the inputs, check known answers, and export a single HTML file with its formula and assumptions intact.

From your formula to their next decision.

  1. State the model. Set labels, input limits and exclusions. Start with team capacity, training cohorts or process lead time, then add fields for your own method.
  2. Check known answers. Enter sample inputs and independently calculated expected results. A mismatch blocks saving and export.
  3. Save and hand over. Save a version, download the HTML calculator, and share the file through your usual client handoff. Later edits need a new saved version.

One file. An inspectable formula.

The export includes a calculation form, formula version, assumptions, expected-result checks and print controls. The formula engine is embedded in the file; it makes no network requests.

Inputs entered in the exported calculator are not transmitted or saved. The authoring studio saves versions only in the current browser. Keep copies of important exports.

Know the limits.

Use the studio for bounded numerical planning. It supports arithmetic, min/max, and rounding. It does not connect to live data, manage client accounts, or replace independent professional review.

Cloud backup, account sync and paid subscriptions are not active. The current preview has no checkout.

Before you build

Work through a team capacity calculation, including productive time, rounding and scheduling limitations.

What is a portable HTML calculator?

A web page containing its own form and calculation code. HTML Workflows embeds the formula and example checks in the downloaded file, so the calculation does not depend on a hosted API.

Does a passed check prove my model is correct?

No. A passed check means the formula reproduces the expected answer for the inputs you supplied. You still need to choose meaningful cases and confirm that the assumptions fit the real task.

Can I return to an earlier version?

Yes, while its history remains in your browser. Restore a saved version in the studio. Saving subsequent edits creates another version and retains the original. Clearing browser site data removes that local history.

Can I buy a subscription now?

Not yet. The local studio is available to try; subscriptions and account services are still being prepared.
