Trace
Full substitution
Follow the path from the formula to its substituted values and final answer. A reviewer can examine the calculation directly.
Engineering calculation platform
Calculations with a trace you can review.
Build calculations from connected blocks. Follow the variables, inspect the substitution, and keep the engineering review attached to the work.
A standalone web application. No Microsoft 365 subscription is required.
Online-first — runs in any modern browser, no install; projects export as JSON.

An output remains linked to its source block. Cycle detection helps identify invalid dependency loops.
- Formula
- M = F × L
- Substitution
- M = 10 kN × 2 m
- Result
- M = 20 kN·m
- Input source
- Load inputs → F, L
Engineering review required
Boundary-rule advisories stay visible alongside the result. This arithmetic example does not establish compliance with an engineering standard.
Review the formula, substituted values, declared units and resulting quantity together.
- Author
Prepare the blocks, declared inputs and supporting references.
- Checker
Inspect the formula and substitution trace on the calculation being reviewed.
- Approver
Review the calculation revision and its outstanding advisories.
Human review
Author, checker and approver work from the same calculation trace.
Illustrative workflow · Sample inputs and arithmetic. These panels explain the product; they do not run its calculation engine.
Calculations as connected records
Keep the reasoning with the result.
A calculation needs inspectable inputs, relationships and evidence throughout its review.
Link
Live variable references
Use an output from one block in another. Explicit relationships and cycle detection help keep dependencies understandable.
Check
Boundary-rule advisories
Surface governing-standard thresholds alongside the work, including limits relevant to drift, bearing capacity and slenderness.
Review
Role-based collaboration
Author, checker and approver roles work with the same trace. A qualified person remains responsible for the engineering result.
Template library
Begin with a defined calculation.
Use published templates across engineering disciplines, with their recorded engineering notes and validation evidence where applicable.
Evidence stays part of the work.
Formula, input, unit, reference and review are part of the calculation record. The template library supports the workflow without replacing a qualified person’s judgement.
AI assistance remains governed, with a person in the loop on engineering results.
Access and portability
Work in your browser.
No Office dependency
SynthoFlow runs as a standalone web application. No Microsoft 365 subscription or Office add-in deployment is required.
Exportable projects
The experience is online-first. Projects export as JSON, keeping portability visible alongside the authoring workflow.
