What kinds of assumptions does it detect?

It flags USD currency references, imperial units, ambiguous US date formats, US-specific holidays, northern-hemisphere season assumptions, idioms and sports metaphors, given/family name splits, and default Western placeholder names.

Why is MM/DD/YYYY a problem?

Most of the world reads dates as day/month/year, so 03/04 is March 4 in the US but April 3 nearly everywhere else. The ambiguity causes real errors, so the checker recommends ISO dates or spelled-out months.

Will it catch every cultural issue?

No. It is a heuristic pattern scanner, not a substitute for a native reviewer. It catches the common, mechanical pitfalls so a human can focus on the subtle ones.

Why flag idioms and sports metaphors?

Phrases like "hit it out of the park" or "the whole nine yards" rely on shared cultural knowledge and translate poorly. Non-native readers and translation models both stumble on them.

Does my prompt get uploaded?

No. All scanning runs locally in your browser using pattern matching. Nothing leaves the page.

Cultural Sensitivity Prompt Checker

Cultural sensitivity prompt checker

A prompt written from a US or Western default quietly excludes most of the planet. It prices things in dollars, dates them as MM/DD, weighs them in pounds, celebrates Black Friday, and tells the model to “hit it out of the park.” For a product serving Lagos, São Paulo, or Tokyo, those assumptions produce wrong or alienating output. This checker scans for the common, mechanical ones so you can fix them before they ship.

How it works

You paste your prompt and, optionally, your target regions for context. The tool runs a set of pattern rules over the text and flags matches in several categories: currency assumptions, imperial units, ambiguous US date formats, region-specific holidays, northern-hemisphere season language, idioms and sports metaphors, given/family name assumptions, and default Western placeholder names. Each finding comes with a short note on why it is a problem and how to fix it. It is a heuristic — it catches the obvious traps, not every nuance.

Tips and notes

Use ISO dates. A date like 2026-12-25 is unambiguous everywhere; MM/DD is not.
Offer both units, or metric. Most of the world thinks in kilograms and Celsius.
Watch the seasons. A “summer sale” launches into winter south of the equator — anchor on months or events instead.
Pair it with a human. Run the scanner first, then have a native reviewer from each market read the prompt. The tool removes the easy mistakes so they can spot the hard ones.
