Website owners and marketers can use a reported hidden list of roughly 100,000 words and phrases to understand how Apple\u2019s iPhone keyboard affects autocomplete and swipe-typing behavior. The restrictions do not block direct typing, but they can make certain terms harder to enter on mobile devices and raise broader questions about how platform recommendations are governed.<\/p>\n

What the Hidden List Contains<\/h2>\n

According to Reuters, Apple maintains a hidden list of about 100,000 words and phrases that its iPhone keyboard will not suggest. The estimate comes from independent researcher Derik Kauffman, founder of Blacklight, a startup that checks scientific papers for errors, and excludes Chinese characters.<\/p>\n

The list includes offensive language and terms related to drugs, sex and violence. It also contains political expressions from several countries, including \u201cDictator Trump,\u201d \u201cSleepy Joe,\u201d \u201cright wing conspiracy,\u201d \u201cTibetan independence,\u201d \u201cUnited Ireland,\u201d \u201coccupied territories\u201d in Hebrew and \u201cimmigration too high\u201d in French.<\/p>\n

Some restrictions appear inconsistent. Reuters reported that the keyboard allows users to swipe-type \u201cread smut\u201d but not \u201cread gay smut,\u201d while Kauffman found that his iPhone struggled to recognize \u201cbad boy\u201d and \u201cwhite man,\u201d yet had no trouble with \u201cbad girl\u201d or \u201cblack man.\u201d<\/p>\n

How the Restrictions Work<\/h2>\n

The list affects suggestions and swipe-typing, not the ability to type a word directly. Users can still enter any word they want. Apple said its keyboard is designed to avoid suggesting offensive or inappropriate language.<\/p>\n

Kauffman discovered the list in September after noticing unusual differences in how the keyboard handled certain phrases. He used AI coding tools to investigate and eventually found a file inside Apple\u2019s operating system.<\/p>\n

Matt Suiche, an engineer at security company Tolmo, independently recovered the same list and found that it closely matched Kauffman\u2019s findings, according to Reuters. The outlet tested a sample of entries on an iPhone and found that the phrases were either missing from suggestions or difficult to enter through swipe-typing.<\/p>\n

What This Means for Website Owners and Marketers<\/h2>\n

The list is not a published keyword file or a documented search-engine penalty, so it should not be treated as a definitive list of terms that affect rankings. However, it provides a concrete example of how a platform can shape autocomplete behavior without preventing a person from entering a query.<\/p>\n

For a site audit, the practical question is whether important brand names, product terms, campaign phrases or audience language behaves differently across devices and input methods. A phrase that appears in metadata, visible content and structured data can still be harder to produce with swipe-typing on an iPhone, even when it can be typed normally.<\/p>\n

Because the restrictions are described as operating-system behavior, a search engine can still crawl, index and return a page containing a listed phrase. The reported list therefore offers no basis for removing legitimate language from metadata or content. It is more useful as a prompt to check user experience across input methods and to separate confirmed technical findings from speculation about search visibility.<\/p>\n

Why Transparency Matters<\/h2>\n

David Greene of the Electronic Frontier Foundation told Reuters that users should be informed about the list and given the option to change it. He said, \u201cThis is something that should not be secret.\u201d<\/p>\n

Apple did not explain why political expressions were included, according to Reuters. The company said that users can type any word they want and that its keyboard avoids suggesting offensive or inappropriate language. The findings nevertheless raise questions about how much control Apple should have over recommended words, particularly when the restrictions extend beyond profanity.<\/p>\n

Apple\u2019s keyboard has previously received criticism for handling swear words, including replacing \u201cf*ck\u201d with \u201cducking.\u201d Apple\u2019s Notes app has also censored handwritten swear words.<\/p>\n

What to Do Now<\/h2>\n
    \n
  1. Test the phrases that matter to your business.<\/strong> On an iPhone, compare tap typing with swipe-typing for brand names, product names, campaign tags and essential calls to action.<\/li>\n
  2. Check autocomplete on mobile.<\/strong> Record whether important phrases appear in suggestions and whether related alternatives differ by device.<\/li>\n
  3. Keep important terms visible.<\/strong> Ensure essential names, labels and calls to action appear in visible page content and metadata rather than relying on keyboard suggestions alone.<\/li>\n
  4. Separate platform behavior from search impact.<\/strong> The reported list concerns Apple\u2019s keyboard, not a documented Google ranking rule. Do not remove legitimate terms from a site without evidence of a search-related problem.<\/li>\n
  5. Document inconsistencies.<\/strong> When the same phrase behaves differently across words or languages, record the device, input method, language and exact result so the issue is reproducible.<\/li>\n<\/ol>\n

    FAQ<\/h2>\n

    Does Apple\u2019s iPhone Keyboard Block the Listed Words?<\/h3>\n

    No. Users can still type any word they want. The restrictions affect autocomplete suggestions and can make some phrases difficult to enter through swipe-typing.<\/p>\n

    How Large Is the Hidden iPhone Keyboard List?<\/h3>\n

    Independent researcher Derik Kauffman conservatively estimates around 100,000 entries, excluding Chinese characters.<\/p>\n

    Does the List Directly Affect Search-Engine Rankings?<\/h3>\n

    No documented link was reported. The list concerns suggestions and swipe-typing in Apple\u2019s keyboard, while search engines can crawl and index text containing the listed phrases.<\/p>\n
