STANDARDS WE DRAW TOMcGoldrickNSGCIEEE 315IEC 61131-3ISA-5.1UML 2.5Howard-RaiffaNewick
II·ENGINES

32 engines, one chat.

Specialist engines (•) draw the diagrams competitors can't — typed grammars, standards-compliant output. General engines (·) cover the day-to-day flowcharts, mindmaps, and timelines.

III·VS THE DEFAULTS

The diagrams ChatGPT can't draw.

Generic AI gives you ASCII art. Mermaid gives you a flowchart. We give you the diagram a clinician, an inspector, or an investor will accept.

IV·WHY TYPED

Routed. Validated. Engineered.

A typed pipeline beats a hopeful prompt. Three things every diagram goes through before you see it.

Routed automatically

Your description picks the engine.

A circuit goes to schematex-circuit. A sequence goes to mermaid-sequence. A mindmap goes to markmap. You don't pick the syntax — we route by intent and serve the right grammar to the model.

Validated server-side

No broken renders ever leave the server.

If a generated DSL fails to parse, we retry server-side until it's clean. The user only sees the final, valid render — never a stack trace, never a half-drawn box, never a malformed arrow.

Engineered for precision

Each diagram type has its own grammar.

32 typed engines means each diagram type has a maintained DSL with first-class error messages — not a single general-purpose AI guessing syntax. Schematex covers the diagrams nobody else can draw.

V·FROM THE FIELD

What people draw with it.

Paraphrased from real sessions — engineering proposals, clinical assessments, B2B teams replacing tools that couldn't keep up.

“Our electrical engineers are always too busy. I needed an SLD for a customer proposal — drafted it in ten minutes.”

B2B · SALES CONSULTANT · INFRASTRUCTURE

“Our BI tool couldn’t make a bubble matrix for license × usage. Yours did.”

B2B · BI ANALYST · ED-TECH, NL

“Replacing SolidWorks for preliminary P&IDs. The hydraulic schematics are surprisingly good.”

INDUSTRIAL ENGINEER · ES

“Drafted a clinical genogram for a case assessment. Saved me thirty minutes of manual layout.”

CLINICAL PSYCHOLOGY · STUDENT
VI · NOTE

A diagram is a contract. Every line, every arrow, every label is a claim about the system. A typed grammar is the only way to keep that claim honest.
