What you can do with the DeepSeek app on Windows 11: uses, tricks, and local mode

If you use Windows 11 and are curious about the full potential of the DeepSeek app, you've come to the right place. This guide brings all its features and tricks to your desktop with a practical approach, written in Spanish (Spain), focusing on what you can actually do on your everyday PC. Here you'll find everything from DeepSeek-R1 reasoning mode to internet searching, file management, history management, and options for running it locally.

DeepSeek has made a strong entrance thanks to its open approach and competitive performance, as it can be used both on the web and locally. On Windows 11, you can integrate it into your workflow, use it as a browser-based search app, and, for privacy, run it with tools like Ollama or LM Studio . Below, we break down all its features in detail so you can get the most out of it without missing anything important.

What is DeepSeek and why is it worthwhile on Windows 11?

DeepSeek is an open-source conversational AI system with permissive licenses (MIT) and two flagship model lines: V3 (very strong in comprehension and generation) and R1 (focused on reasoning). It has been trained surprisingly efficiently, with fewer resources than industry giants, yet still achieves a competitive level in programming, logic, and mathematics . It works flawlessly in Spanish: simply write to it in our language and it will automatically detect the context.

It's important to keep some limitations in mind: the online chatbot has restrictions on sensitive topics due to regulatory issues, and like any AI, it can make mistakes or even experience "hallucinations." Even so, it's a very attractive option for Windows 11: you can use it via the web, on mobile devices with its official app, and even install it on your computer with tools that make it convenient and accessible.

First steps: official website, mobile apps and no registration options

To use the online version, go to the official website, click on Start Now, and complete the login process with your email or phone number (you can link your Google account to speed things up). Accept the terms of service, and that's it: the chat is now enabled for questions in Spanish and other languages.

If you prefer to have DeepSeek with you at all times, there's a mobile app for Android and iOS. The mobile interface is clear, and on both iPhone and Android, you can adjust the app's language; it supports Spanish and other regional languages ​​(such as Basque and Catalan, and Galician on iOS), which is unusual and very convenient if you live in a multilingual environment.

Integrate DeepSeek as an app-like search engine into your Windows 11 browser

A practical way to keep DeepSeek handy on Windows 11 is to "pin" it as a browser application, allowing you to use it almost like a primary search engine. While there isn't yet direct integration as a traditional search engine, you can log in to its website and create a site app from your browser (using Chrome/Edge's app feature). This opens it in its own window with immediate access from the taskbar, making it your central search engine.

There are third-party extensions that require an API key, but if that's confusing, this app-like approach gives you a quick experience: you open DeepSeek "as an application," type your query, and receive answers on the fly, avoiding dependence on Google or Bing when you just want a direct answer.

Deep reasoning with DeepSeek-R1

Below the chat text box, you can activate the reasoning option, identified as DeepThink (R1). In this mode, the AI ​​dedicates more processing power to your query to provide more thoughtful answers , useful for programming problems, mathematical proofs, or complex explanations. It doesn't simply "spew out" an answer; instead, it analyzes context and previous interactions and sometimes displays its thought process before the final response.

This reasoning works particularly well with attached documents, although it doesn't integrate with web search. Interestingly, for now, it doesn't incur any additional cost on the online platform. You can switch between the standard model and R1 on the fly; you can even ask it to "think again" and, with the button active, get a more robust response.

Search the internet and cite sources without leaving the chat

DeepSeek can search the web to give you up-to-date information. By activating Search mode below the input box, the system scans for relevant articles and synthesizes the answer based on its findings. It's ideal when you need recent data or want to verify figures and news without leaving the conversation.

Furthermore, you can audit the source: above the response, you'll see a button that says something like "Found XX results." Clicking it opens a column with all the articles used. Within the text, each paragraph contains short, numbered references ; hovering your mouse over a number displays a preview of the article, allowing you to open it at its original link. For serious work, these quick citations make all the difference.

Manage history, new chats, and response versions

Your conversation history is organized in the left sidebar. Each conversation is a separate chat, and you can create new ones when you change topics to keep everything tidy . It's easy to revisit past conversations, rename chats, and even add emojis to the title for quick categorization.

If you're not satisfied with the first response, tap "Regenerate" and the AI ​​will create another version from scratch based on the same prompt. You can also edit a previously sent prompt (pencil icon) to modify your request without starting the chat again. DeepSeek saves the dialogue "branches" with each edit or regeneration, so you can explore all the generated variations.

Below each answer, you'll find a button to copy the formatted text (bold is preserved), as well as options to vote with a thumbs up or thumbs down. This feedback helps refine the model's behavior over time.

Languages: Spanish by default and multilingual support

You can write directly in Spanish and the chat will respond in the same language. If any reply appears in English, add a note like "Reply in Spanish" and the next one will be in our language . You can also start a conversation with "Speak to me in Spanish" or ask them to "Explain it to me as if I were five years old" to encourage a simpler version with everyday examples.

The mobile app offers the interface in several languages ​​(including Basque, Catalan, and, on iOS, Galician). The web interface is usually in English or Chinese , but the model understands Spanish perfectly and converses fluently.

Files and OCR: PDF, DOCX, TXT and images with text

In Windows 11, you can attach documents for DeepSeek to read and summarize. Upload a PDF, text file, or DOCX file and ask it for a structured summary or specific questions about its content. It's very useful for extracting main ideas, generating bullet points, or highlighting key data from long reports.

For now, AI applies OCR to images: it extracts the text and works with it, but it doesn't analyze the visual elements of the photo. On mobile devices, you'll see three inputs: Document (for PDF, DOCX, etc.), OCR Image (you upload an image to read its text), and OCR Photo (taken with the camera). It can also handle XLSX spreadsheets, allowing you to request summaries or checks on their cells.

Writing, proofreading, and on-the-fly translation

If you need help with your text, ask it to correct spelling and grammar, or to rewrite it with a clearer or more professional tone. You can define the length, structure, and style, as well as specify the context (for example, a business email). DeepSeek can generate email drafts , templates with fields for data, and versions for personal or professional use.

For translations, simply define the command and the text. You can write something like: translate "I want to read" into English, or paste a large block of text and request that it be returned in a specific language . If you wish, separate the command and the content with a colon and quotation marks; the model understands the intention.

Comparisons, pros and cons, tutorials and summaries

Another practical feature is requesting lists of pros and cons for everyday decisions, from choosing a pet to deciding whether to start an exercise routine . You can set how many points you want and the focus (only advantages, only disadvantages, or both).

It will also create comparisons between products or brands highlighting key differences, and can use web searches for up-to-date information. With tutorials, it offers concise steps (without screenshots), ideal for short tasks. Keep in mind that errors may occur, so it's advisable to verify the information for complex processes.

Creativity: poems, lyrics, stories, jokes, and games

If you're looking for something creative, DeepSeek composes poems and song lyrics tailored to your theme and rhyme scheme. It can also generate jokes in various styles or children's stories with your chosen age group and characters. It's a great tool for light writing projects or for entertaining the family.

You can also suggest games to them. For example, you could have them act as the game master for a role-playing game, defining the setting and characters. They'll create an introduction and ask you what you'd like to do, crafting a customized text adventure .

Programming, web templates, and Excel formulas

In software development, DeepSeek generates code snippets, explains algorithms, and assists with debugging. It supports popular languages ​​(Python, JavaScript, Java, C++, and more) and suggests improvements to features . It should be viewed as a starting point: verify the output and integrate it judiciously, as it may contain errors.

He also writes basic HTML to build a website structure and specific elements (hero page, form, etc.). If you get stuck with spreadsheets, ask him for Excel formulas tailored to your needs: he'll provide the function template and examples to help you understand how to apply it correctly.

Buying guides, reviews and leisure recommendations

To get equipped, request buying guides and product lists with detailed descriptions and features. They don't usually provide purchase links, but they do offer product names and key differentiators . Activating the web search function will give you an extra boost of up-to-date information.

In device reviews, the focus is more on a summary sheet than an in-depth review, but it's useful for seeing key specifications at a glance. For a break, it also recommends TV shows, movies, games, or books based on genres or titles you've enjoyed.

Health, exercise and nutrition: with a cool head

DeepSeek offers exercise lists for different muscle groups and explains how to perform them. For nutrition, it can create menus and recipes based on your needs or the ingredients you have at home. Always use it as a general guide: it doesn't provide diagnoses, and for health-related matters, it's best to consult with a professional.

Installing DeepSeek locally on Windows 11: Ollama and LM Studio

If you're concerned about privacy or want server independence, you can install "distilled" versions of the model on your Windows 11 PC (see the Windows 11 requirements for local AI ). With Ollama , you can load models from the command line, and LM Studio provides a user-friendly graphical environment for downloading, managing, and running models.

In LM Studio, find the DeepSeek variant that best suits your hardware (R1 is recommended for reasoning), click Download and follow the guide to install DeepSeek on your computer , and you'll see the model in the My Models section. From there, use Load Model to run it in the background while you browse, even offline. The full version of the model is resource-intensive and demands a lot of processing power; therefore, the scaled-down versions are the sensible option for most home PCs.

Security, privacy, and limits to consider

Like any AI, DeepSeek can make mistakes. Review critical responses and request new versions if you have any doubts. Keep in mind that the online instance may censor political topics , and that the main infrastructure is hosted outside of Spain; as a precaution, avoid sending sensitive or confidential information if you don't control where it's processed.

File support covers common text formats and OCR for images, but it doesn't analyze visual content. The web interface is usually in English, although the conversation flows in Spanish. In reasoning mode, the internal string it displays sometimes appears in English , even though the final response is in Spanish.

DeepSeek versus other popular AIs

To place it in a business and productivity context, this summary will serve as a quick guide on how it compares to known alternatives. The key factors here are its open-source nature, the performance achieved, and the operating costs.

Tips to get more out of it

Make clear and specific requests. The more specific you are, the more accurate the response will be. If the first attempt isn't satisfactory, break the task down into steps and ask for an outline, then work your way down to the details section by section.

Specify the language if necessary. If an output is received in English, add a parenthetical note requesting a response in Spanish. Provide relevant context (text, code, or variables) and experiment with reformulations to refine the result.

If you handle sensitive data, consider using LM Studio or Ollama locally. It requires some configuration, but you'll gain complete privacy and offline availability—perfect for environments with compliance requirements.

Extra features and new features to watch out for

In addition to the above, remember that you can create sample exams (carefully review the solutions), request article structures, and ask for style guides to maintain consistency in long-form content. Regarding visuals, there are image-oriented models from Janus Pro/Janus-Pro-7B that offer greater multimodal capabilities, while in the current chat environment, images are processed via OCR.

Advanced organization of daily life

Rename chats with emojis to categorize them by project, delete conversations in bulk from settings when you clean up your space, and edit old messages to branch out the dialogue based on hypotheses. If you create a workflow, for example, "idea → outline → draft → review," you'll see that DeepSeek adapts to iterative processes very smoothly.

Delete your account and data control

From the settings, you can delete your account whenever you want with just a couple of taps. The system will guide you through the process and ask for final confirmation . Although deletion is simple, keep in mind that minimal records may remain in accordance with the service's policy.

There's no need to overcomplicate things to take advantage of DeepSeek on Windows 11: with R1 reasoning mode, web search with sources, document support (and OCR for images), answer editing and regeneration, and the ability to run it locally with LM Studio or Ollama, you have everything you need to make it your daily assistant. Use your preferred languages , organize with history and emojis, manage privacy based on context, and remember that, while powerful, it's still AI: verify critical information and rely on the citation option when you need solid support.
