You searched the App Store for “DeepSeek,” found four results, and three of them charge a subscription. Which one is real? That uncertainty is exactly what scammers count on, and it is why this guide on DeepSeek how to verify official app exists. Since the DeepSeek chatbot hit the No. 1 spot on iOS in early 2025, fake clones, malicious desktop installers, and lookalike websites have multiplied — security firms have catalogued keyloggers, crypto miners, and phishing pages all wearing DeepSeek’s branding. The official app itself is free, the official website is a single domain, and the publisher name on each store is fixed. Below you get a step-by-step checklist, the exact strings to look for, and the red flags that should make you close the tab.

The short answer: what “official” means for DeepSeek

DeepSeek ships exactly one consumer-facing chat app and one consumer-facing website. Everything else — paid “Pro” clones in app stores, “DeepSeek installer” .exe files from random download portals, Telegram bots, browser extensions promising “DeepSeek Premium” — is unaffiliated at best and malicious at worst. If you want to download DeepSeek, go to its official page: www.deepseek.com. You can also download it from the official Apple App Store. Investigate, in full, every app you download and check its security and privacy.

Two anchors do most of the verification work:

• Domain: deepseek.com for marketing and the app landing page; chat.deepseek.com for the web chatbot; platform.deepseek.com for the developer console and API keys.
• Publisher name in app stores: the developer field must read “Hangzhou DeepSeek Artificial Intelligence” (the company’s full registered name). Anything else is a clone.

If the link, the publisher, or the price doesn’t line up with those anchors, stop. The rest of this guide explains how to confirm each one in under a minute, on every platform.

Why this matters: the threat landscape in 2025–2026

DeepSeek’s January 2025 launch was the fastest AI app climb on record. In January 2025, DeepSeek launched its first free chatbot app, “DeepSeek – AI Assistant”, which rapidly became the most downloaded free app on the iOS App Store in the United States, surpassing even OpenAI’s ChatGPT. That kind of attention attracts impersonators within days.

Security researchers have since documented several distinct attack patterns. Various malware campaigns followed, which included Crypto-miners, fake installers, DeepSeek impersonator websites, and fake DeepSeek mobile apps. McAfee Labs separately found that files named DeepSeek-R1.Leaked.Version.exe or DeepSeek-VL2.Developer.Edition.exe appear legitimate, but once a computer runs the code in that file, it connects to hostile servers and downloads a cocktail of malware — ranging from stealthy keyloggers and password stealers to coin miners that can quietly siphon your computer’s resources.

App stores aren’t immune either. A user posting on Apple’s own community forums described downloading an app from the App Store that claimed to be DeepSeek AI, purchasing the premium subscription thinking it was the official version, and finding it was fraudulent — despite paying for premium, the app simply did not work. The official DeepSeek mobile app is free; any “premium subscription” prompt inside an app calling itself DeepSeek is your first signal that you have the wrong one.

The crypto angle is even uglier. Researchers identified the domain “deepseek-shares.com,” registered on January 29, 2025, falsely presenting itself as an official DeepSeek investment platform claiming to offer DeepSeek Pre-IPO shares to lure potential investors. DeepSeek is privately held and has issued no IPO. Any site offering “DeepSeek shares” or a “DeepSeek token” is a scam.

The 7-point verification checklist

Run through these checks before you tap Install or Run. They take roughly 60 seconds combined.

1. Confirm the domain. The only domains DeepSeek operates for the consumer chat and developer platform are deepseek.com, chat.deepseek.com, and platform.deepseek.com. Type them, don’t follow ad links.
2. Check the app store publisher name. Must read “Hangzhou DeepSeek Artificial Intelligence” (or its short form “DeepSeek”). Not “DeepSeek AI Pro,” not “DeepSeek Chat Plus,” not a developer name you don’t recognise.
3. Check the price. The official mobile app is free with no in-app subscription gate for basic chat. Any paid tier inside the app is suspect.
4. Confirm the social handles. DeepSeek operates only three official accounts — on WeChat, X, and Chinese social media app RedNote — and has warned users of imposters charging fees or promoting bogus cryptocurrencies.
5. Reject any “investment” or “token” pitch. DeepSeek has not done an IPO and does not have a cryptocurrency.
6. Reject CAPTCHA-then-keystroke prompts. If a “DeepSeek” page tells you to press Win+R and paste a string, close it immediately. That is the Vidar infostealer pattern documented across multiple security vendor reports.
7. Cross-check via Hugging Face or GitHub. The verified deepseek-ai organisation pages on both platforms link out to the same deepseek.com and chat.deepseek.com destinations — useful as a third-party reality check.

Platform-by-platform: how to verify on each device

iPhone (iOS App Store)

Open the App Store, search “DeepSeek,” and look for the listing whose icon is the dark-blue whale on a white background. Scroll down to the “Information” section. The “Seller” or “Developer” field should reference DeepSeek’s Hangzhou entity. The official iOS listing carries the bundle behaviour described in Apple’s own product page (“Powered by DeepSeek’s latest flagship model, it delivers faster responses and more powerful features”) — but more important than marketing copy is that there is no paid subscription tier and no in-app purchase upsell on the genuine listing. Cross-reference the App Store URL against the link on deepseek.com if you are unsure.

Android (Google Play)

Search “DeepSeek” and tap the result whose developer name matches the iOS listing. Tap “About this app” → “App support” to see the publisher’s verified contact email; the official one is [email protected]. Side-loaded APKs claiming to be “DeepSeek Mod” or “DeepSeek Premium APK” are a different app entirely and should never be installed.

Mac and Windows desktops

This is where most malware lives. DeepSeek does not currently publish first-party native desktop installers; the supported desktop experience is the browser at chat.deepseek.com. DeepSeek has launched mobile apps for both iOS and Android with great success, but you can also use it directly in your desktop browser without needing to download anything. If you genuinely want a packaged desktop window, use a Progressive Web App wrapper from your browser rather than an executable from a download portal — and read our notes on DeepSeek on Mac and DeepSeek on Windows for safer setups.

The web chat

The genuine browser product lives at chat.deepseek.com. Anything else — chat-deepseek-ai.com, deepseekai.app, deepseek-chat.io — is third-party. Some are harmless mirrors; some are phishing. The official site shows DeepSeek-V4 Preview as the current default model in the chat picker, with a DeepThink toggle for thinking mode. If a “DeepSeek” page is asking you to connect a crypto wallet, scan a QR code to “verify,” or pay to chat, leave.

Side-by-side: official vs fake

Red flags to walk away from

Beyond the checklist, a handful of behaviours are reliable poison signals. The McAfee report on bogus installers describes one of the worst: attackers use brand impersonation with DeepSeek’s icons and color scheme, redirect users to a fake captcha page, ask the user to open a verification window by pressing the Windows + R key and then pressing CTRL + V to verify their identity, and on clicking ‘OK’ install malware that can steal browser and financial information from the system. No legitimate verification flow ever asks you to paste anything into the Run dialog. Close the page.

Two more patterns to refuse on sight:

• Crypto wallet connect prompts. A scam site presented itself as an official DeepSeek investment platform, claiming to offer DeepSeek Pre-IPO shares to lure potential investors. DeepSeek does not run any token, presale, or staking programme.
• “Free Premium” download links from search ads. Ads frequently outrank organic results during news cycles. If the URL doesn’t end in deepseek.com, ignore it — even if it appears at the top of Google.

If you already installed something suspicious

Treat it as a credential incident. Three steps in order:

1. Disconnect first. Take the device off Wi-Fi while you investigate. Do not log into anything sensitive in the meantime.
2. Uninstall and scan. Remove the app via the OS uninstaller, then run a reputable on-device antivirus scan. Mobile users should also revoke any subscription via the App Store or Play Store account page.
3. Rotate credentials. If you typed an email and password into the fake app, change that password everywhere it was reused, and turn on 2FA. If you connected a crypto wallet, move funds to a new wallet from a clean device.

If the bogus app charged a subscription, you can request a refund through Apple’s Report a Problem flow or Google Play’s purchase history page. Apple has historically refunded these once the app’s review history makes the fraud obvious.

Bonus: how to verify the API surface, not just the app

If you are a developer and want to confirm you are talking to DeepSeek’s real API rather than a proxy, the canonical base URL is https://api.deepseek.com and the canonical chat endpoint is POST /chat/completions — the OpenAI-compatible endpoint. The current model IDs are deepseek-v4-pro and deepseek-v4-flash (DeepSeek V4 Preview, released April 24, 2026). Legacy IDs deepseek-chat and deepseek-reasoner still work but route to deepseek-v4-flash until they retire on 2026-07-24 at 15:59 UTC. The API is stateless — your client must resend the full message history with every request, which is the opposite of how the chat app behaves.

A minimal Python sanity check using the OpenAI SDK looks like this:

from openai import OpenAI

client = OpenAI(
    base_url="https://api.deepseek.com",
    api_key="sk-...",
)

resp = client.chat.completions.create(
    model="deepseek-v4-flash",
    messages=[{"role": "user", "content": "ping"}],
    max_tokens=16,
)
print(resp.choices[0].message.content)

If the response comes back from any other base URL, you are pointed at a proxy. Get your key from platform.deepseek.com directly, never from a third-party “key reseller.”
