Language support: Translation apps typically cover more languages. LLMs may offer higher quality for supported languages, especially complex pairs.
Integration and accessibility: Many translation apps work offline and integrate well with other services. LLMs usually require an internet connection but offer versatile solutions.
Cost considerations: Translation apps often have free tiers. LLMs may involve usage costs or subscriptions for advanced features.

Google Translate vs. ChatGPT Translation

Original British English text

Afternoon tea is a quintessentially British tradition, dating back to the 1840s. It's not merely a cuppa, but a proper sit-down affair with a spread of dainty sandwiches, scones with clotted cream and jam, and an assortment of cakes. Many Brits consider it a treat, often indulging at posh hotels or quaint tea rooms for special occasions.

Google Translate version

Afternoon tea is een typisch Britse traditie, die teruggaat tot de jaren 1840. Het is niet zomaar een kopje thee, maar een echte sit-down-aangelegenheid met een keur aan heerlijke sandwiches, scones met clotted cream en jam en een assortiment aan taarten. Veel Britten beschouwen het als een traktatie, en gaan er vaak op uit in chique hotels of gezellige tearooms voor speciale gelegenheden.

De afternoon tea is een typisch Britse traditie, die teruggaat tot de jaren 1840. Het is niet zomaar een kopje thee, maar een echt gezelschap met een assortiment verfijnde sandwiches, scones met clotted cream en jam, en een verscheidenheid aan taarten. Veel Britten beschouwen het als een traktatie en genieten vaak in chique hotels of gezellige tearooms bij speciale gelegenheden.

Key Differences

Cultural terms
- ChatGPT: verfijnde sandwiches and gezelschap suggest a more refined understanding of the British tradition of afternoon tea, which is often associated with elegance and social status.
- Google Translate: heerlijk and keur might imply a more casual or down-to-earth approach, focusing on the enjoyment of food without emphasising the traditional elegance.
Idiomatic expressions
- ChatGPT: Uses een echt gezelschap, which feels more idiomatic in conveying the idea of a formal gathering.
- Google Translate: een echte sit-down-aangelegenheid is a direct translation that may not resonate as strongly with native Dutch speakers as an idiomatic expression. It sounds slightly more cumbersome.
Cultural context
- ChatGPT: Positions afternoon tea as a sophisticated event, reflecting the cultural significance of this tradition in British society, which values formal gatherings and elaborate tea settings.
- Google Translate: The phrase gaan er vaak op uit implies a more active, casual experience of going to enjoy tea, which may downplay the ceremonial aspect of afternoon tea and reflect a more modern, informal approach.
Nuanced vocabulary
- ChatGPT: Words like verfijnde and gezelschap evoke a sense of luxury and formality, aligning with the traditional view of afternoon tea as a special occasion.
- Google Translate: The use of heerlijk and keur feels more approachable and may suggest an emphasis on the enjoyment of the food rather than the event's formality. This vocabulary is less formal and may resonate more with everyday experiences.
Natural flow
- ChatGPT: The structure and vocabulary create a smooth and sophisticated reading experience that aligns well with the elegance associated with afternoon tea.
- Google Translate: While still coherent, the use of phrases like gaan er vaak op uit disrupts the flow slightly. It feels more fragmented and less elegant, which may not fully capture the intended cultural experience.

This example illustrates how ChatGPT emphasises the sophistication and cultural significance of afternoon tea, using refined vocabulary and idiomatic expressions that reflect traditional values. Google Translate offers a more casual interpretation, emphasising enjoyment and accessibility over formality. This highlights the diversity in how cultural traditions can be expressed and understood through language.

Best Practices for Translation Prompts

Custom translation prompts allow for more relevant and accurate translations, especially when dealing with cultural nuances, technical terminology, or a specific writing style. Some best practices include:

Provide context: Specify source/target languages, purpose, and audience.
Clarify tone: Indicate desired formality and style.
Highlight cultural elements: Note idioms or cultural references needing adaptation.
Specify key terminology: Provide preferred translations for crucial terms.
Request alternatives: Ask for options on important phrases.
Iterate: Refine translations through follow-up prompts.
Address ambiguities: Ask for clarification on unclear parts of the source text.
Verify specialised content: Request confirmation of technical or field-specific terms.

Example Custom Prompt

If you have an HTML document containing a mix of text and code, you may not want the HTML tags and structure to be altered during translation. In such cases, using a custom prompt to instruct the model to translate only the visible text while preserving the HTML code intact can ensure that the translation is both accurate and retains its intended formatting.

Prompt: Translate only the visible text within the HTML document, ensuring that all HTML tags, attributes, and structural elements remain completely unchanged. Focus solely on converting the content between the tags while preserving the original code format and integrity.

Practical Scenarios for Choosing Tools

Custom prompts for specific needs: Custom prompts can be particularly useful when you need a highly tailored translation that matches a specific tone, style, or purpose. By crafting detailed prompts, users can guide LLMs to focus on certain aspects of the content, such as maintaining cultural sensitivity or emphasising key ideas. This approach is especially beneficial for creative projects, marketing materials, or any context where the precise expression of intent is crucial.
Quick communication needs: If you are travelling or need to communicate basic information quickly, specialised translation apps are the go-to tool. It is ideal for translating signs, menus, or simple conversations.
Creative or nuanced content: For content that requires a higher degree of nuance, such as storytelling or creative writing, LLMs shine. They can understand subtle cues and produce translations that feel more natural and contextually appropriate.
Formal or technical writing: In cases where you need accuracy in specialised fields, consider using a combined approach. Start with translation apps to get a general translation, then refine it using an LLMs to add precision and context-specific language.
Privacy and security
- Non-sensitive content: When you need to translate personal blog posts or general information, free public tools like Google Translate or DeepL are sufficient and convenient.
- Personal privacy-sensitive content: If translating personal records or sensitive information, select offline tools or paid services with strong privacy policies and robust data protection guarantees to safeguard your data effectively.
- Critical or legal translations: When handling highly confidential or legal documents, opt for professional human translation services to ensure maximum security, accuracy, and compliance with legal standards.

Future Outlook

Translation technology is evolving rapidly, with AI-driven models becoming increasingly sophisticated. Future trends include better integration of automated tools with nuanced, context-sensitive translations, enhanced by human expertise. We can expect advancements in real-time capabilities, specialised domain translations, and improved support for emerging market languages. These developments, coupled with greater scalability and accessibility, aim to achieve high-quality results with minimal user effort while maintaining the crucial balance between AI efficiency and human insight.

Conclusion

Each translation tool has its strengths and weaknesses. Translation apps are ideal for quick, simple translations, while LLMs excel at providing nuanced, context-sensitive translations. Choosing the right tool depends on your specific needs, whether it's speed, accuracy, or adaptability.

To determine which tool to use, ask yourself: How important is nuance? Is speed a priority? Is the content specialised or creative? These questions can help guide your choice.
