Yes, DeepSeek works in English. Open the official English website or go straight to DeepSeek Chat and write your question in English. To change the web chat menus, open your account menu and choose Settings → General → Language → English.
If the menus are already in English but an answer comes back in Chinese, address the reply itself: ask for a complete English version and include the language requirement in your next task. The website language, chat interface, and generated answer are different things. Choosing the right one to change saves you from adjusting settings that do not solve your problem.
| What you want to change | Where to start | What to check afterward |
|---|---|---|
| The main website is in Chinese | Open deepseek.com/en/ or select EN in the website header. | The homepage navigation and product descriptions are in English. |
| The chat menus are in Chinese | Use the web chat’s account menu, then Settings → General → Language. | The interface labels display in English. |
| A generated reply is in Chinese or mixes languages | Request a complete English rewrite and clarify the language in the task. | The actual answer, including headings and explanations, follows your request. |

Open the official DeepSeek English site
Use deepseek.com/en/ for DeepSeek’s English homepage. If you land on the Chinese homepage, select EN next to 中文 in the header. That changes the website you are reading; it is not an instruction to the model about your next answer.
The English site links to the same official chat service at chat.deepseek.com. You do not need to find an “English model” or install a separate English edition to ask questions, draft text, explain code, or work with English source material. Tell the assistant what you want done and supply the relevant text or context.
Choose chat for conversations, the platform for API access
For an ordinary conversation, open DeepSeek Chat and follow the sign-in instructions if prompted. The DeepSeek Open Platform is the developer destination for API access and account management. Landing there when you want a chat window can look like a language or navigation problem, but it is a different part of the service.
DeepSeek’s Open Platform terms, section 2.1, say that the platform and chat service use the same account. They still serve different purposes. An API key is not something you need to paste into the official chat to make it speak English. If you cannot sign in, follow the account recovery or help options on the official service; changing the language will not resolve an account-access problem.
Check the actual website address before entering your DeepSeek credentials. A page title or familiar logo does not make a third-party “English login” page official. Use the service links above rather than giving your account password to an unrelated site.
Chat-Deep.ai is an independent guide. The official links above take you to DeepSeek’s services; a third-party chat page may have its own accounts, limits, and language controls.
How to change DeepSeek’s interface to English
In the official web chat
On DeepSeek’s web chat, the language selector sits in the account settings. Use this route:
- Open the account menu at the bottom of the sidebar.
- Choose Settings, then General.
- Open Language and select English from the list.
- Close the settings and check that the menu labels are now in English.
Choose English explicitly if that is the interface you want, rather than leaving the selector on System. If the sidebar is collapsed, expand it to reach the account menu. Once the menus are readable, you can return to the conversation; you do not need to start a new chat just to inspect the interface language.
A browser’s “translate page” command is a separate feature. If automatic page translation is active, turn it off temporarily when checking DeepSeek’s own labels or comparing an original reply with its translation. Otherwise, you may be reading the browser’s translated display without realizing it.
On iPhone or Android
Get the mobile assistant through the official download page, under DeepSeek app. The same page also lists Harness desktop downloads, which are not the mobile chat app. The official iPhone and iPad listing includes English among its supported interface languages, so an English-only replacement app is unnecessary.
If your installed app offers a Language or App Language option in its settings, choose English there. Mobile versions can arrange these controls differently from the web chat. You can still type an English question and specify an English answer while you sort out the menus.
Android also provides a per-app language setting for supported apps. In Google’s documented route, open the phone’s Settings → System → Languages → App Languages, select the app, and choose the language. Use this route if DeepSeek appears in that list. Google notes that only supported apps are listed and some of the steps require Android 14 or later; phone makers may arrange settings differently.
If DeepSeek is absent from that list and you cannot find a language option in the app, open the official web chat in your phone’s browser and use its language selector. This also gives iPhone users an alternative when the app’s controls differ. You do not have to change the language of your entire phone just to request an English answer.
What to do when DeepSeek answers in Chinese
First identify what is actually in Chinese: a menu, the source you supplied, or the answer you need to use. An English interface does not prove that every generated response will follow an English-only request. Work through the reply and the instructions before reinstalling the app or changing account settings.
1. Ask for the complete answer in English
When an otherwise useful reply is in the wrong language, repair that reply instead of rebuilding the whole conversation. You can send:
Rewrite your previous answer entirely in English, including headings and explanations.
Preserve the useful details, examples, numbers, and qualifications.
Do not replace it with a shorter summary.
Keep code, URLs, proper names, and any text I explicitly asked you to quote unchanged.This is an editorial prompt example, not a special DeepSeek command or a guaranteed fix. Read the revised answer for omitted sections as well as language. If you need a translation of every sentence, say so; if you need an English summary, specify the scope of that summary. Those are different jobs.
2. Restate the task and output language together
A one-word follow-up such as “English” leaves the task underspecified. Put the language alongside the work you want done, especially when the source contains Chinese:
Summarize the source below in English for a reader unfamiliar with the topic.
Explain the main points and any limitations stated in the source.
Keep names, dates, and numbers accurate. Do not add facts from outside the source.
Use English for the answer, even where the source is in Chinese.
Source begins:
[PASTE THE RELEVANT TEXT]
Source ends.Check that an earlier instruction does not ask for Chinese output, a bilingual answer, or verbatim source quotations. A language requirement should also allow necessary exceptions: you may want Chinese names or quotations preserved while their explanation is in English. Spell out that distinction instead of asking for both “English only” and unchanged Chinese quotations without explanation.
3. Separate the source from your instructions
Label pasted material so the requested language and task are easy to distinguish from the document being discussed. A Chinese article can be the source for an English answer; its language does not have to become the language of your report. Conversely, a request to translate an English paragraph into Chinese should allow Chinese in the translated passage.
For a long task, state which output needs English: headings, table labels, commentary, or the whole final response. If only one paragraph switches languages, ask for that paragraph to be corrected while retaining the parts that are already right. This avoids losing useful work through an unnecessary full rewrite.
4. Start a new chat if the old instructions keep getting in the way
Copy the current task, the necessary source, and your language rule into a new conversation. Leave out abandoned instructions that no longer apply. You do not need to delete the old chat: keep it as a reference if it contains decisions or material you still need.
A new conversation will not know an earlier brief unless you supply it. “Continue in English” in an empty chat is therefore less useful than restating the actual job. Once an answer follows the intended language, check the content as usual; a fluent rewrite can still miss a number, qualification, or source detail.
When the problem needs feedback rather than another prompt
Language mixing is not always evidence that you wrote a bad instruction. DeepSeek’s official changelog described reduced Chinese–English mixing in its September 2025 V3.1-Terminus update. That is a historical provider statement, not proof that a particular current reply has the same cause or that the issue has disappeared.
If a clear English request in a fresh conversation still produces an unusable answer, use the service’s feedback option. Include a short example of the request and reply, whether you used the website or app, and the app version if relevant. Remove private material from the example. Repeating increasingly forceful language instructions is unlikely to help you explain a reproducible problem to support.
Use DeepSeek for English writing and translation
Choose the transformation before choosing the tone. Translating preserves the source in another language; summarizing selects its main points; rewriting improves how the existing message reads. A request that combines all three without priorities can produce a smooth answer that drops information you meant to keep.
Translate Chinese text into English
For a complete translation, specify the English variety, the information to preserve, and what to do with ambiguous wording. Replace the placeholder with the passage you want translated:
Translate the Chinese text below into natural American English.
Preserve the full meaning, names, numbers, units, and paragraph structure.
Use the terminology in this glossary where it applies: [GLOSSARY, OR REMOVE THIS LINE].
If a phrase is ambiguous, explain the uncertainty briefly after the translation.
Do not invent missing context.
Text:
[PASTE CHINESE TEXT]For technical or business material, a short glossary can prevent inconsistent terms across paragraphs. Read dates, negatives, quantities, product names, and units against the original. Natural English is useful, but it is not evidence that every detail survived the translation.
Translate English into Chinese without conflicting rules
Remove or qualify an earlier “English only” instruction when the requested output is Chinese. You can separate the translation from any explanation:
For this translation task, write the translated passage in Simplified Chinese.
Translate the English source faithfully and keep names, numbers, and units accurate.
Write any notes about ambiguity in English after the translation.
Source:
[PASTE ENGLISH TEXT]Specify Simplified or Traditional Chinese when the distinction matters to the audience. If the translated text will be published or used for an important decision, have someone able to assess both languages review the meaning rather than judging it only by appearance.
Rewrite English for the audience you have in mind
“Improve my English” is a reasonable start, but a usable brief says whether the task is a grammar correction, a clearer explanation, or a change in tone. For example:
Edit the following email into clear, friendly British English.
Preserve the message, names, dates, and commitments.
Do not add promises or make the tone more formal than necessary.
Return the revised email, then briefly explain any substantial change in meaning.
Email:
[PASTE EMAIL]Change British to American English if that suits the reader. If you are learning, ask for explanations of a few important corrections; if you need a ready-to-send email, ask for the finished message first. Our DeepSeek prompt templates cover broader writing, study, and research tasks.
Request English answers through the DeepSeek API
For an application, put the answer-language rule in the messages you send. The Chat Completions specification supports system and user messages; it does not document a general language: "en" parameter for text replies. A small request body can look like this:
{
"model": "deepseek-flash",
"messages": [
{
"role": "system",
"content": "Write explanations and answers in English. Preserve code, URLs, proper names, and quotations when necessary. If the user requests translation into another language, use that language for the translated passage."
},
{
"role": "user",
"content": "Explain the difference between a summary and a translation, with a short example."
}
]
}This is the JSON body for a POST /chat/completions request, not a complete command. Use the authentication and endpoint setup in DeepSeek’s first API call guide. Keep your API key on the server rather than embedding it in browser code.
For follow-ups, send the language instruction and the conversation messages the answer depends on. Inspect the actual request if your application unexpectedly changes languages: a frontend setting labelled “English” is not enough unless your application passes an appropriate instruction. Also check for another message that requests a different output language.
When thinking is enabled, the API distinguishes reasoning_content from the final content. Evaluate the final answer your user will receive instead of treating a separate reasoning field as the completed reply. For reusable application rules and message roles, see our DeepSeek system prompts guide.
Frequently asked questions
Is there a separate DeepSeek English version?
There is an English version of the official website, and the chat service and app support English use. You do not need a separately branded “DeepSeek English” model. Start from the official links above and choose the interface and output language you need.
Can I use DeepSeek in English for free?
DeepSeek describes its official mobile assistant as free on the download page, and the App Store listing is free. English support is not presented as a separate paid upgrade. Developer API usage is a different service, so do not treat free app access as free API usage.
Why does DeepSeek reply in Chinese when the interface is English?
The menu language and the generated response serve different purposes. Check your current request, earlier instructions, and any source text that needs a specific treatment. Ask for the full answer in English; if the behavior persists with a clear request, report the example rather than assuming the interface setting proves the model must comply.
Can I make every DeepSeek reply English permanently?
An explicit English instruction makes your preference clear, but it is not a guarantee for all future conversations. Include it in the brief for a new chat when it matters. In an API application, keep the reusable instruction in the requests you send and check the final output.
Can DeepSeek use British or American English?
You can request either in the task. Specify the intended audience and whether you want spelling changes alone or a broader rewrite. Review the result for consistency, especially when source text contains product names, quotations, or terminology that should stay unchanged.
Can I keep Chinese terms inside an English answer?
Yes: ask for English explanations while preserving the particular names, quoted phrases, or glossary terms you need. For example, request the Chinese term once in parentheses after its English explanation. This is clearer than demanding English-only text while also requiring Chinese quotations.
Do I need to reinstall DeepSeek to change the language?
Start with the website or app’s available language setting. Reinstalling is unnecessary for selecting English in the web interface, and it does not replace an answer-language instruction. If your mobile controls differ, update through the official store or use the browser route while you check the app’s settings.
Choose the fix that matches the problem
If you only need to read the menus, set the interface to English and return to your work. If the answer is in the wrong language, keep the useful content and request a complete English rewrite. For your next conversation, include the task, the source, and the output language together. That gives you a clear result to check without turning a simple language preference into a complicated setup.
