Quick Answer
The official English-language DeepSeek homepage is https://www.deepseek.com/en/. For normal browser chat, use chat.deepseek.com; the direct account page is chat.deepseek.com/sign_in. Developers should use the separate DeepSeek Platform for account billing and API-key management, then consult the official API documentation. Bookmark the exact address you need instead of searching for it each time. DeepSeek-themed domains, apps, browser extensions, and “API resellers” are not official merely because they use the name or logo.

These links were checked against DeepSeek’s own homepage and official product navigation on July 29, 2026. Storefronts may redirect to a country-specific version. Before installing, confirm that the listing still identifies the developer as DeepSeek or Hangzhou DeepSeek Artificial Intelligence Co., Ltd.; do not rely on the app name alone.
How to Verify a DeepSeek Domain Before You Sign In
- Read the complete hostname. The safe web destinations in this guide use
deepseek.comor an exact subdomain such aschat.deepseek.com,platform.deepseek.com,api-docs.deepseek.com, orstatus.deepseek.com. - Read from right to left. In
deepseek.com.example.org, the controlling domain isexample.org, not DeepSeek. A brand name placed earlier in an address proves nothing. - Check spelling and punctuation. Extra words, substituted letters, doubled characters, unusual hyphens, or a different domain ending are warning signs. A polished copy of the real interface can still be a phishing page.
- Require HTTPS without browser warnings. Encryption is necessary, but the padlock alone does not establish ownership: scammers can obtain HTTPS certificates too.
- Use the official homepage as your directory. When uncertain, open deepseek.com/en/ yourself and follow its Product links. Save the resulting pages as bookmarks.
- Let your password manager help. A password manager that recognizes the real sign-in host should not automatically fill credentials on a look-alike domain. Treat an unexpected failure to match as a reason to stop and inspect the address.
Fast signs of a fake site or app
- It promises “lifetime API access,” unlimited paid API credit, or a special account unlock.
- It asks for a DeepSeek password, API key, one-time verification code, crypto payment, wallet seed phrase, or remote access outside an official DeepSeek destination.
- It pushes an APK, desktop installer, configuration profile, or browser extension from a file-sharing site.
- Its support message creates urgency: “verify now,” “account will close,” or “server migration requires your key.”
- The app title says DeepSeek but the store developer and package/app ID do not match the verified listing above.
Login, App, API, Pricing, and Status: Which Page Do You Need?
Web chat and login
Use chat.deepseek.com to open the official browser chat. If you want to start at the account screen, use the exact sign-in URL. Registration and sign-in options can differ by device or region, so follow only the choices displayed on that official page. Do not give an authentication code to anyone claiming to be support, and do not approve a login you did not initiate.
Official mobile apps
For iOS or iPadOS, use App Store listing ID 6737597349. For Android, use Google Play package com.deepseek.chat. Store search results may include many unrelated apps that mention DeepSeek models. Verify the developer, identifier, and support domain before installing. If the official listing is unavailable in your storefront, use the official web chat where permitted; do not sideload a copy from an unfamiliar download site.
Developer platform, API docs, and pricing
The consumer chat and developer API are related products but separate workflows. Go to platform.deepseek.com to manage developer access, create or revoke API keys, view balance, and handle API billing. Use api-docs.deepseek.com for the current quick start and reference. DeepSeek’s documentation states that API usage is billed by tokens and that prices can change; check the live pricing table before estimating costs or topping up. Never expose a key in a screenshot, public repository, tutorial form, or ordinary chat message. If a key may have leaked, revoke it on the official platform and replace it.
Service status
If web chat is slow, login fails, or API requests return server errors, check status.deepseek.com before changing passwords or repeatedly regenerating keys. The official status page distinguishes web-chat and API health and provides incident history. A green status does not rule out a local browser, network, account, or regional issue, but it is the right first check for a broad outage.
Region and Availability Caveat
DeepSeek availability is not identical everywhere. App-store listings, account methods, features, payment options, and access can vary with country, platform, local rules, age requirements, or an organization’s security policy. A valid global link may therefore show a regional notice or no install button. Do not bypass a legal, workplace, school, or device-management restriction. Check the official page and your local requirements, and avoid treating a VPN or third-party APK as proof that access is authorized or safe.
Official DeepSeek vs. Chat-Deep.ai
| Question | Official DeepSeek services | Chat-Deep.ai |
|---|---|---|
| Who operates it? | DeepSeek | An independent informational website |
| Official account login? | Yes, through chat.deepseek.com or platform.deepseek.com | No |
| Creates or stores DeepSeek API keys? | The official developer platform manages keys | No |
| Purpose in this guide? | Chat, apps, developer access, documentation, billing, and status | Independent guidance that points readers to verified official destinations |
Chat-Deep.ai is not DeepSeek’s official website and is not affiliated with or endorsed by DeepSeek. Chat-Deep.ai does not need—and should never ask for—your DeepSeek password, one-time login code, or API key. Enter those credentials only in the appropriate official DeepSeek service. For help specifically with interface language and writing prompts in English, see our English-language guide.
Common Mistakes to Avoid
- Clicking the first search result: advertisements and copied pages can appear above the genuine destination. Use a bookmark or the verified table.
- Trusting a logo: names, icons, screenshots, and interface designs can be copied in minutes.
- Confusing chat with the API: access to the web chat does not mean API usage is included. API keys, token billing, and balances belong on the developer platform.
- Pasting a key into a third-party tool without review: a key is a credential that can incur charges. Understand where it is stored and sent.
- Downloading an unofficial app: a store listing that mentions “DeepSeek” may be a wrapper or unrelated client, not the official assistant.
- Assuming an error means an account hack: first check the official status page, then your network and browser, before taking account-recovery action.
Frequently Asked Questions
What is the official DeepSeek website?
The official English homepage is https://www.deepseek.com/en/. It links to DeepSeek’s chat, app, platform, API documentation, pricing, and service-status destinations.
What is the direct DeepSeek login link?
For the consumer web chat, use https://chat.deepseek.com/sign_in. Developers may need the separate platform.deepseek.com account area for API keys and billing.
Are the web chat and API the same service?
No. The web chat is the interactive consumer interface. The API is for software integrations and uses developer credentials, token-based billing, documentation, and account balance on the official platform.
Is DeepSeek free?
DeepSeek’s homepage presents free access to its web experience, but availability and limits can change. The developer API is separately priced by token usage. Always read the official pricing page for current rates and billing rules.
How can I identify the official DeepSeek app?
Use App Store ID 6737597349 or Google Play package com.deepseek.chat, and verify the developer is DeepSeek or Hangzhou DeepSeek Artificial Intelligence Co., Ltd. Do not identify it by icon or title alone.
Where can I see current API prices?
Use DeepSeek’s official Models & Pricing page. Prices and available models can change, so a copied price in an old article, video, or calculator may be outdated.
What should I do if DeepSeek is down?
Check the official service-status page. If no incident is listed, test your network, reload the official page, check regional or organizational restrictions, and use only official account-recovery options.
Is Chat-Deep.ai an official DeepSeek service?
No. Chat-Deep.ai is an independent informational website. It does not provide official DeepSeek login, issue API keys, or require your DeepSeek password or API key.
