I Tested ChatGPT vs DeepSeek With 11 Language Learning Prompts — Here’s The Surprising Winner

In the evolving landscape of AI language models, ChatGPT and Deepseek stand as two powerful contenders in language learning assistance. I embarked on a detailed comparison, putting both AI platforms through their paces with 11 carefully selected language learning prompts from basic grammar explanations to complex conversational scenarios. The results were fascinating and unexpected.

While ChatGPT has long been the go to choice for language learners worldwide, Deepseek emerged as a formidable competitor, demonstrating capabilities that challenge the status quo. Through systematic testing across various language learning aspects, I uncovered patterns that shed new light on how these AI tools can enhance language acquisition.

Ready to discover which AI assistant truly excels in language education? Let’s dive into the revealing results!

1. Describe Your Day

ChatGPT’s response is the stronger piece. It uses more sophisticated vocabulary (“languidly,” “wafting”) and creates a richer narrative that blends professional tasks with intellectual growth. The writing style is more evocative, with sensory details and varied sentence structures.

While Deepseek’s response is clear and relatable with its specific timeline and everyday activities, it uses simpler language and a more basic chronological structure, making it less engaging overall.

2. Favorite Meal

Describe your favorite meal and why you like it. Include ingredients, taste descriptions, and any memories associated with it.

Comparing both responses, ChatGPT’s carbonara description proves more effective than Deepseek’s lasagna account. While both cover the required elements, ChatGPT creates a more engaging narrative by weaving together vivid sensory details (“silkiness,” “smoky crunch”) with cultural context and emotional resonance.

The writing flows naturally, subtly acknowledging its AI nature while maintaining an immersive storytelling quality. In contrast, Deepseek’s response, though comprehensive, takes a more clinical approach with its bullet-pointed ingredients and straightforward descriptions.

The direct AI acknowledgment and structured format make it feel more like a recipe than a personal reflection. ChatGPT’s response ultimately wins for its superior ability to balance technical detail with emotional engagement, creating a more memorable and compelling reading experience.

3. Conversation Practice

Create a short dialogue in [target language] for a [specific scenario, e.g., ordering at a restaurant, asking for directions, or introducing yourself.

Comparing both dialogues, ChatGPT’s networking event scenario emerges as the stronger piece. While Deepseek’s directions dialogue is functional and clear, ChatGPT’s conversation demonstrates greater sophistication and natural flow.

The networking dialogue showcases more complex character development, with Alex and Jordan revealing their professional backgrounds and interests organically.

It builds toward a meaningful outcome (future coffee meeting) while incorporating relevant contemporary topics like AI and e-commerce. The conversation feels more authentic with detailed responses matching how professionals interact at a networking event.

In contrast, Deepseek’s dialogue, though perfectly serviceable for its purpose, follows a more basic question-and-answer format typical of direction-giving scenarios. Both achieve their goals, but ChatGPT’s version shows superior character depth, natural dialogue progression, and real-world authenticity.

4. Listening Comprehension

Recommend a podcast, song, or YouTube video in [target language] for intermediate learners and provide a brief summary of its content.

ChatGPT’s response is more focused and effective, recommending a specific podcast (“The English We Speak”) with detailed, practical information about episode length, content structure, and learning benefits.

While Deepseek’s response provides a broader recommendation of the BBC Learning English YouTube channel, it feels less targeted and actionable. ChatGPT’s recommendation includes specific details about the 3-4 minute format and how it helps with idioms and native-like speech, making it more immediately useful for intermediate learners.

Though both mention BBC Learning English resources, ChatGPT’s more specific, concise focus on a single podcast makes it the stronger recommendation for learners looking to improve their English skills.

5. Role Play Conversation

Imagine you're booking a hotel room in a foreign country. Write out a dialogue between you and the hotel receptionist.

6. Grammar Guide: Rules, Applications, and Examples

I want you to act as a grammar guide. Can you explain [what grammar rule or concept you’re struggling with] and provide instructions on [how to apply the rule or concept]? Can you also give me examples of [how the rule or concept works in practice]?

ChatGPT provides a more structured and comprehensive explanation based on the two responses in the images addressing subject-verb agreement. It better organizes the information with clear sections including the rule definition, how to apply it, and specific warnings about tricky cases. The formatting is more visually appealing with clear headings and a well-organized hierarchy.

While Deepseek’s response is correct and includes good examples, it’s slightly less comprehensive and doesn’t address potential complexities like collective nouns or subjects joined by “and” or “or.” Both provide accurate information, but ChatGPT’s response offers more practical value by including guidelines for application and potential pitfalls to watch out for.

7. Common Grammar Mistakes to Avoid

Provide me a list of common grammar mistakes to avoid when speaking/writing in [target language].

Winner: Deepseek

In this comparison, Deepseek provides a more effective response. While both tools list common grammar mistakes, Deepseek’s format is superior because it includes a complete teaching structure for each error: showing the mistake, providing the correction, and explaining the rule. This three-part approach makes it easier for learners to understand and apply the concepts. Additionally, Deepseek uses dividing lines between sections and better formatting, making the content more readable.

While ChatGPT gives accurate information, its presentation is more basic, simply stating definitions without showing explicit examples of incorrect usage or how to fix them. The practical approach of showing both wrong and right examples in Deepseek’s response makes it more valuable for learning purposes.

8. Key Phrases in [Target Language] for [Topic/Situation]

Provide me with examples of common phrases used in [target language] to describe [certain situation or topic].

Chatgpt Reply:

Winner: Deepseek

In this comparison, Deepseek provides a more comprehensive and practical response. While both tools organize workplace phrases into categories, Deepseek offers more examples per category and covers a broader range of common workplace scenarios (team collaboration, meeting management, and deadlines). Its examples also include more contemporary business idioms and phrases like “touch base,” “loop me in,” and “get everyone on the same page,” which are frequently used in modern workplaces.

ChatGPT’s response, while well-structured, focuses more narrowly on feedback and information-seeking scenarios, with fewer examples per category. The greater variety and quantity of practical examples in Deepseek’s response makes it more valuable for someone looking to learn workplace communication phrases.

9. [Number] Everyday Expressions in [Target Language]

Provide me a list of [number] common expressions in [target language] that I can use in everyday conversation.

Winner: Deepseek

Deepseek provides a superior response for everyday English expressions. Its presentation is more concise and efficient, fitting all 15 expressions in a single view with clear dash separators between the expression and its meaning. The expressions chosen are more diverse and include more contemporary casual phrases like “I’m beat” and “I’m all ears,” which are highly useful in daily conversation.

ChatGPT’s response, while also accurate, uses a more space-consuming bullet-point format and includes some less commonly used expressions like “get the ball rolling.” Additionally, Deepseek’s explanations are more concise while still being clear, making it easier for learners to quickly grasp and remember the meanings. The overall selection of phrases in Deepseek’s response better represents the variety of situations encountered in everyday conversation.

10. Expand Your [Target Language] Vocabulary: [Number] Words About [Topic]

Help me expand my vocabulary in [target language] by suggesting [number] words related to [topic].

Chatgpt Reply:

Deepseek Reply:

Winner: Deepseek

Both tools take different but effective approaches. ChatGPT focuses specifically on technology-related vocabulary, providing detailed explanations of modern technical terms like blockchain, AI, and cloud computing.

However, Deepseek offers a more diverse range of sophisticated vocabulary across different contexts, including emotional states, character traits, and abstract concepts. Deepseek’s response is superior because it includes parts of speech for each word (marked in parentheses), presents a broader range of vocabulary that can be used in various situations, and offers more concise yet clear definitions.

The vocabulary chosen by Deepseek is also more useful for advanced English communication, including words like “ephemeral,” “serendipity,” and “quintessential” that can enhance one’s expressive capabilities across many contexts, rather than being limited to a single field.

11. Language Learning Tips

What are some effective strategies for improving [specific skill, e.g., speaking, listening, or reading] in [target language]?

Chatgpt Reply:

Deepseek Reply:

Winner: Deepseek

Deepseek provides a more comprehensive and well-structured response for language learning strategies. While ChatGPT focuses solely on listening skills, Deepseek covers multiple language skills (speaking and listening) with specific, actionable strategies for each. Deepseek’s response is superior because it offers more concrete recommendations, including specific app suggestions (Duolingo, Babbel, ELSA), detailed techniques like shadowing and transcription practice, and mentions specific resources (BBC, NPR). The formatting is also clearer with better categorization and subheadings.

Additionally, Deepseek’s inclusion of unique strategies like “Record Yourself” and “Transcription Practice” shows a deeper understanding of language learning methodologies. The practical, multi-faceted approach and specific tool recommendations make Deepseek’s response more immediately useful for language learners.

Based on the content provided, I’ll create a similar analysis comparing ChatGPT and DeepSeek in language learning contexts.
