Write it.
HEXI fixes it.
You learn why.

Dialect-calibrated prompts. Error detection inline — not at the end. Every correction explains the grammar rule and adds the pattern to your HEXI compound memory.

"Output processing — noticing gaps in your production — is what drives acquisition, not input alone." — Swain (1985)

Not a spell checker — a grammar intelligence

Inline — not end-of-essay

HEXI flags errors per sentence as you write — not at submission. Keeps attention on the rule, not on scanning a red document.

Rule → pattern → memory

Each correction includes a grammar rule, a dialect example, and enters compound memory. Not just correction — acquisition.

Error type taxonomy

Morphological, syntactic, pragmatic, lexical — classified separately. Your error profile drives what Construct™ drills next.
