A thread in r/webdev drew 62 upvotes and 132 comments between Sep 14, 2026 – Oct 14, 2026. People get by with Human translators and Lokalise QA, and that still leaves this job open. Hotness is 3.65, Hot. Real but moderate pain. Clear willingness to pay. The thread drew 62 upvotes and 132 comments. Only clumsy or enterprise-only options. A 1-2 week mvp. A first version is weekend-easy, about 2 weeks, priced at $200 a month or more and charged as a done-for-you service. The pain, the source, the alternatives, the scope notes, and the questions on this page are free to read and free to build from. The agent starter prompt is the paid part.

Who has it

What people use now
- Human translators
- Lokalise QA
A way through
A fast QA service for AI-translated/AI-built sites before launch that finds semantic, cultural and layout errors that technical QA misses.
MVP scope
- Give agencies, exporters, and developers a way to do this in one sitting: Catch meaning, cultural and layout errors in AI-localized sites before launch, the bugs normal QA misses.
- Persist the result and show it again after a reload.
- State the empty case when there is nothing to show yet, with one next step.
- Charge later with a done-for-you service, at $200 a month or more. The free path must finish the core job once.
- Ship the service business only. Leave Human translators to keep the jobs they already do well.

Questions
Is this idea already taken?
People already use Human translators, Lokalise QA. Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.
How hard is a first version?
Weekend-easy. A tight MVP is about 2 weeks (2 weeks), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.
Who would pay, and how?
The audience is agencies, exporters, and developers. Charge a done-for-you service, and test a price at $200 a month or more. Willingness to pay is one input to Hotness, not a promise that someone will buy.
Can I use the evidence?
Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
