In development — early access coming

Engineering calculations you can verify, not just trust.

SynthoFlow is a calculation platform built on self-contained blocks: live variable linking with cycle detection, a substitution trace that always equals the result, and advisory checks against the standards that govern your work.

No pricing yet. No sign-up form. Just a platform we're building in the open with the people who'll use it.

Substitution trace

Every number in the result has to earn its place.

Each calculation block shows its full path from symbolic formula to substituted values to final answer. There's no hidden spreadsheet cell, no black box: the trace is the result, by construction — if the numbers don't reconcile, the block tells you.

Block 07 — Bolt Group Shear AISC 360 · J3
given n = 6, V = 84 kN, Fnv = 372 MPa
formula φRn = φ · Fnv · Ab · n
substitute φRn = 0.75 · 372 · 380 · 6
compute φRn = 636.1 kN
check V ≤ φRn → 84 ≤ 636.1 PASS

Live variable linking

Blocks connect like code, not like copy-paste.

Output a variable from one block and reference it in another — SynthoFlow keeps the dependency graph live and watches for cycles as you build. A block that would create a circular reference is flagged before it can corrupt a result.

Dependency graph of linked calculation blocks Four calculation blocks connected by live variable links; one link attempts a cycle and is flagged as blocked. Loads · Block 01 Geometry · Block 02 Deflection · 04 Capacity · 05 Combined · 06 cycle blocked

Boundary-rule advisories

Governing standards, checked as you work.

SynthoFlow can advise against the boundary rules in the standards you already design to — drift limits, bearing capacities, slenderness ratios — surfacing a flag the moment a result crosses a line, so review happens at the point of calculation, not after.

Template library

195 published templates. Every one checked before it ships.

Templates span 16 engineering disciplines, and each one is blind-verified and externally validated through a multi-station content pipeline — built independently, checked independently, and published with cited reference cases so you can trace a template back to its source.

Role-based collaboration

Built for the way engineering teams actually review work.

Assign roles across a project — author, checker, approver — so the people who need to see a calculation see it, and the people who need to sign off on it can. Every role sees the same trace; nobody has to take a result on faith.

AI-assisted, governed

AI capabilities, behind an enterprise gateway you control.

We're building AI-assisted capabilities on top of SynthoFlow's block model — routed through a governed enterprise gateway rather than bolted on as a side feature. This work is still in development; nothing here ships until it meets the same verification bar as the rest of the platform.

Multi-language output is also planned as a platform-family capability, so calculation blocks can present the same verified trace in the language a reviewing team works in.

In development — early access coming

No launch date. No pricing. No sign-up form — just a conversation.

SynthoFlow isn't live yet, and we'd rather tell you that plainly than dress up a waitlist. If verifiable engineering calculations are a problem you're working on too, talk to us at SynthoCore.
