Open Microsoft Edge or Chrome. Go to chat.deepseek.com. Click the install icon (⊕) in the address bar → "Install as app". DeepSeek opens in its own window, pinned to your taskbar. Done.
Press Win + S → search "Microsoft Store". Search for "DeepSeek". Click Get (free). Launch from Start menu. This installs the same web app as a proper Windows application with taskbar icon.
For fully offline use: Download Ollama for Windows (.exe installer). Then run a model in Command Prompt or PowerShell:
ollama run deepseek-r1:7bFirst run downloads the model (~4.5 GB for 7B). After that, it works 100% offline.
Create a free account at chat.deepseek.com with Email, Google, or Apple ID to sync conversations across devices. No account needed for basic chat.
Open Chrome or Edge on Windows 10. Navigate to chat.deepseek.com. In Chrome: click the three-dot menu → More Tools → Create Shortcut → check "Open as window". In Edge: click ⊕ in address bar → Install. DeepSeek now runs as a standalone window.
Open Microsoft Store from Start menu. Search "DeepSeek". If listed, click Get. Note: The Store listing may require Windows 10 v1903 or later. Check Settings → Windows Update if it doesn't appear.
Download Ollama's Windows installer from ollama.com. Supports Windows 10 64-bit. After installing, open PowerShell:
Requires 8 GB RAM minimum. GPU acceleration with NVIDIA cards (GTX 1060+) makes it significantly faster.
Several open-source developers have built Windows desktop wrappers at github.com/doxdk/deepseek-desktop. These wrap the DeepSeek web interface in an Electron window. Note: not official — review the source code before installing.
Open Google Play Store → search DeepSeek. Tap the result by developer "DeepSeek". Tap Install (free). Launch from your app drawer. This is the safest and easiest option for Android users.
Visit download.deepseek.com/app on your Android browser. Download the APK. Go to Settings → Security → Install unknown apps → allow your browser. Tap the downloaded APK to install. Only use the official link — never third-party APK sites.
After install, open DeepSeek. The developer in your device's App Info should show DeepSeek or Hangzhou DeepSeek Artificial Intelligence. If it shows anything else, uninstall immediately — it's a fake.
Open the app. Sign in with Email, Google, or Apple ID for conversation sync. Or tap "Skip" / use as guest — basic chat works without an account. DeepThink, voice, and file uploads are free for all users.
Open Safari, Chrome, or Firefox. Go to chat.deepseek.com. In Safari: File → Add to Dock (makes it a standalone app). In Chrome: ⋮ → More Tools → Create Shortcut. Works on any laptop — Windows, Mac, Chromebook, or Linux.
Install Ollama for macOS (ollama.com). Open Terminal and run:
Works best on Apple Silicon (M1, M2, M3, M4) — runs at 30–60 tok/s. Intel Macs work but are slower. The 14B model needs ~16 GB unified memory.
Download LM Studio for macOS. Click Discover tab → search "DeepSeek R1". Click Download next to your preferred size (7B → 8GB, 14B → 16GB). Click Chat to start. Fully offline GUI — no terminal needed.
Install Ollama via terminal:
curl -fsSL https://ollama.com/install.sh | shThen run ollama run deepseek-r1:7b. Works on Ubuntu, Fedora, Arch, and any major distro. GPU acceleration with NVIDIA CUDA or AMD ROCm supported automatically.

Requirements vary by how you use DeepSeek. Web app needs almost nothing. Offline local AI needs real hardware.
DeepSeek does not have an official standalone Windows desktop application (.exe installer). The best Windows options are: (1) Microsoft Store PWA — search "DeepSeek" in the Store for a native-feeling window. (2) Chrome/Edge install — go to chat.deepseek.com and install it as a web app with one click. (3) Ollama offline — for a fully local, private Windows installation with no internet needed after setup. Avoid unofficial EXE installers from unknown sites — these may be malware.
Three ways: (1) Easiest: Open Chrome → go to chat.deepseek.com → click the ⊕ icon in the address bar → "Install DeepSeek as app". Works on Windows 10 without any download. (2) Microsoft Store: Open Store → search DeepSeek → click Get. Works on Windows 10 v1903+. (3) Offline: Download Ollama for Windows → run ollama run deepseek-r1:7b in Command Prompt for a fully local, private AI.
The safe official sources are: (1) Google Play Store — package ID com.deepseek.chat by developer "DeepSeek". (2) Official website — download.deepseek.com/app. These are the only two safe APK sources. There are hundreds of fake DeepSeek APK sites that may contain malware or spyware — never download from APKPure, APKMirror, or any unofficial site for DeepSeek specifically.
Yes — using open-source model weights. After the initial download, DeepSeek runs 100% offline with zero data sent anywhere. The easiest method is Ollama: install it, run ollama run deepseek-r1:7b (downloads ~4.5 GB once), then it works offline forever. For a GUI without terminal, use LM Studio — browse, download, and chat with DeepSeek models entirely through a desktop interface. Minimum: 8 GB RAM for the 7B model.
On Windows 11: (1) Open Microsoft Edge → navigate to chat.deepseek.com → click the app install icon (⊕) in the address bar → Install. DeepSeek now lives in your Start menu and taskbar. Or (2) Open Microsoft Store (Win+S → "Store") → search "DeepSeek" → Get. For offline local use: install Ollama for Windows and run ollama run deepseek-r1:14b in Windows Terminal for the best balance of quality and speed.
Yes — DeepSeek's official GitHub is github.com/deepseek-ai. It contains model code, technical papers, and training details. However, model weights (the large files needed to run the AI) are hosted on Hugging Face — not GitHub (they're too large, often 160GB+). The GitHub repos are MIT licensed, so you can fork, modify, and build commercial products freely. Third-party Windows desktop wrappers also exist on GitHub (search "deepseek-desktop") but are unofficial community projects.
For any laptop (Windows, Mac, Linux, Chromebook): the easiest method is the web app at chat.deepseek.com — no download, works in any browser, completely free. To install it as a "real" app: in Chrome click ⊕ in the address bar → Install. For offline use on a laptop with 16 GB+ RAM: install LM Studio (Windows/Mac/Linux) and download the DeepSeek R1 14B model — it runs entirely on your laptop with no internet needed.
"DeepSeek app" usually refers to the official mobile app (iOS/Android) from download.deepseek.com/app. "DeepSeek AI download" is a broader term covering all ways to get DeepSeek: mobile app, web PWA, Windows Store, Ollama offline, or downloading model weights from Hugging Face. There's no single "DeepSeek AI installer" — the experience varies by platform. For most users, the web app or mobile app is the right choice. For privacy-conscious users or developers, the Ollama/offline route is better.
Web, Windows, Android, iOS, or fully offline — every version is free with frontier V4 AI models included.
