Grammar layer for AI-generated content, built for non-US English

The moment someone publishes AI-assisted copy for a UK, Australian, Turkish, or Italian audience and a native speaker catches an embarrassing error — that's when they realize the tools they paid for handed them something broken. They already paid for the AI writer. They already paid for the grammar checker. And they still got burned.

This gap persists because the major grammar checkers are trained overwhelmingly on American English and built for human-written prose. AI-generated text has different failure signatures — it over-uses certain constructions, drops articles in predictable patterns in Turkish, and handles Italian verb agreement inconsistently. General grammar tools weren't trained on AI output as a distinct category, so they miss what AI tools specifically break. Meanwhile, the AI writing vendors have no incentive to fix grammar post-generation: their product is measured on output speed and SEO scores, not grammatical accuracy in a second language.

Users are explicit: 'I still need to run all of it through Grammarly to perfect the grammar side' and 'the Italian part is good but with room for improvement.' That's not a minor inconvenience — it's a second tool, a second workflow step, and it still doesn't catch what's specific to AI-generated text in their language.

This is a business because the failure recurs every single time someone generates content. The cost is real: a freelance content writer producing AI-assisted articles for Turkish brands either manually edits every piece (slow) or publishes errors that damage their professional reputation. Neither is acceptable. They would pay a monthly subscription to eliminate that step.

What to build

Build a post-generation grammar and register corrector that plugs into AI writing tools via browser extension and API, trained specifically on AI-generated output patterns in Turkish, Italian, German, and British English, flagging errors that American-English grammar tools systematically miss.

Where to start

Start with Turkish-language AI content correction, where the gap is both large and underserved — there is no credible AI-output-specific grammar tool for Turkish, giving you a structural first-mover position in a language community that is active in content marketing.

The hard part

Building high-quality grammar correction for Turkish specifically requires a morphologically complex language model that is genuinely hard to train well — cheap shortcuts will produce a product that fails the exact users you're targeting, which kills word-of-mouth before it starts.

How it makes money

Monthly subscription per seat, tiered by word volume processed; API access for agencies billed per 1,000 words corrected.
