Is Artificial Intelligence Capitalized? A Grammar and Style Guide for Writers in 2025
When it comes to writing about artificial intelligence, even seasoned writers often pause: should it be capitalized? The short answer is, it depends on the context. Proper capitalization ensures clarity and professionalism, whether you’re crafting academic articles, blog posts, or business documents.
In this guide, we’ll explore the capitalization rules, style guide recommendations, and common scenarios where “artificial intelligence” or its abbreviation “AI” should or shouldn’t be capitalized. By the end, you’ll have a clear understanding of how to write about this fascinating field with confidence and consistency.
Understanding Capitalization Rules for Common and Proper Nouns
In English grammar, capitalization primarily depends on whether a term is classified as a proper noun or a common noun.
- Proper nouns are specific names for people, places, or things and are always capitalized (e.g., “Microsoft,” “Eiffel Tower”).
- Common nouns refer to general categories and are not capitalized unless they start a sentence or appear in a title.
When referring to “artificial intelligence” as a general concept or field of study, it is treated as a common noun and written in lowercase. However, in contexts where “Artificial Intelligence” is part of a title, brand name, or specific entity, capitalization is appropriate.
Examples:
- Common noun: “Artificial intelligence is transforming industries worldwide.”
- Proper noun: “The Center for Artificial Intelligence Research conducted the study.”
When to Capitalize “Artificial Intelligence”
Titles and Headings
In titles and headings, capitalize “Artificial Intelligence” following title case rules. Most style guides recommend capitalizing major words, while minor words (like “and,” “of,” “the”) remain lowercase.
Examples:
- Correct: “The Role of Artificial Intelligence in Modern Healthcare”
- Incorrect: “The role of artificial intelligence in modern healthcare”
Industry-Specific Conventions
Certain industries or organizations may capitalize “Artificial Intelligence” to highlight its importance, especially in branding, product names, or marketing materials.
Example:
- “XYZ Corporation is proud to introduce its new Artificial Intelligence Platform.”
Academic and Formal Writing
In academic papers, follow the capitalization rules outlined in your chosen style guide (e.g., MLA, APA). Generally, capitalize “Artificial Intelligence” only in titles or when referring to a specific program or initiative.
Using “Artificial Intelligence” vs. “AI”
Abbreviating “artificial intelligence” as AI is common in both formal and informal contexts. The abbreviation should always be capitalized, as it represents a proper noun.
When to use AI:
- When space is limited (e.g., in charts or tables)
- To avoid repetition in lengthy text
- In technical or industry-specific documents where the audience is familiar with the term
Examples:
- Formal: “The adoption of AI has accelerated in recent years.”
- Casual: “AI is now a part of everyday life.”
What Style Guides Say About Capitalizing “Artificial Intelligence”
MLA Style
MLA recommends following standard capitalization rules for titles. In running text, “artificial intelligence” should remain lowercase unless it’s part of a proper noun.
Example:
“In this paper, we explore how artificial intelligence (AI) is influencing literature.”
APA Style
APA also suggests lowercase for general terms but capitalizes titles and proper nouns. Abbreviations like AI should be introduced with the full term on first mention.
Example:
“Artificial intelligence (AI) is reshaping education and research.”
Chicago Manual of Style
Chicago style follows similar principles, emphasizing lowercase for common nouns unless they’re part of a title or specific entity.
Example:
“The Department of Artificial Intelligence announced new funding.”
British vs. American English
While the general rules remain the same, British English may use lowercase more frequently in contexts where American English leans toward capitalization.
