Porter's Five Forces: Construction-Pattern Checker for L2 Writing
A writing-checker add-on for language learners that flags misuse of semi-regular constructions — light verbs, preposition choices, argument-structure quirks — by matching text against corpus-attested form-meaning patterns, and reports which constructions each learner keeps missing.
The framework reveals a high-potential niche where the primary threat is not direct competition, but the inertia of general-purpose AI tools. While technical barriers to entry are high due to the need for specialized corpus-linguistic data, the product's success depends on integrating into existing EdTech ecosystems rather than competing as a standalone app.
