Key takeaways
- When Claude seems down, check Anthropic's status page first, then your network, browser and usage limits.
- Claude was introduced by Anthropic in March 2023, with the claude.ai app opening publicly that July.
- Anthropic, an AI safety company founded in 2021, builds and owns Claude.
- Claude comes as a family of models of different sizes, and in free and paid plans for individuals and teams.
- Claude has web, desktop and mobile apps, supports skills, and is one of the model choices inside Cursor.
When Claude AI seems down, the cause is usually a service incident, heavy demand, a usage limit on your plan, or a local network or browser problem. Check Anthropic's status page first; if it shows no incident, the problem is likely on your side. I build AI products that call several model providers, with automatic fallback when one fails, so this page covers outages, Claude's launch and ownership, its model family, safety, plans, apps, skills, video, and Claude inside Cursor.
Why is Claude AI down?
Claude can be unavailable because of an outage or degraded performance on Anthropic's side, very high demand, reaching your plan's usage limit, or problems with your connection, browser extensions or VPN. Error messages often indicate which.

What to do:
- Check Anthropic's status page for incidents on the app or API.
- If it says limit reached, wait for the reset time or check your plan.
- Refresh, log out and back in, or try another browser or the app.
- Disable extensions or VPN temporarily.
- For API users, retry with exponential backoff on overload errors.
For products that depend on an AI model, design for outages: RAG.NextUpgrad falls back across multiple model providers, so users still get answers when one provider has an incident.
When was Claude AI launched?
Anthropic introduced Claude in March 2023, initially to business partners and through its API. The consumer chat app at claude.ai opened to the public in July 2023 alongside Claude 2.
Also asked as: when claude ai launched
Since then, Anthropic has released several generations, including the Claude 3 family in 2024, which introduced the Haiku, Sonnet and Opus sizes, then Claude 4 and newer models. Each generation improved reasoning, coding, context length and tool use. Release dates and model names change often, so check Anthropic's announcements for the latest models.
Who does Claude AI belong to?
Claude belongs to Anthropic, an AI safety and research company founded in 2021 by Dario Amodei, Daniela Amodei and colleagues, several of whom previously worked at OpenAI. Anthropic develops, trains and operates Claude.
Anthropic is a privately held public benefit corporation, with major investments from technology companies including Amazon and Google. Claude is available through Anthropic's own apps and API, and through cloud platforms such as Amazon Bedrock, Google Cloud Vertex AI and Microsoft's offerings. Anthropic is known for research on AI safety, interpretability and its "Constitutional AI" approach to training models with written principles.
How many Claude AI models are there?
Claude is a family of models rather than one. Each generation typically comes in sizes such as Haiku, the fastest and cheapest, Sonnet, the balanced workhorse, and Opus, the most capable, with newer generations adding further options.

In the apps, you can choose among current models; through the API, developers select a model by its ID. Older models are retired over time on a published schedule. Which to use depends on the task: small, fast models for classification and simple chat; larger ones for complex reasoning, coding and long documents. Test the models on your own tasks, because the best choice varies by use case and cost constraints.
Is Claude AI safe to use?
Claude is generally safe for everyday use: Anthropic applies safety training, usage policies and security controls. As with any AI service, avoid sharing sensitive personal data, verify important outputs, and review your privacy settings.
Practical safety tips:
- Do not paste passwords, ID numbers or confidential client data into consumer chats.
- Check privacy settings, including whether your chats may be used to improve models.
- Use Team or Enterprise plans for business data, which offer stronger data controls.
- Verify facts, code and legal or medical information before acting.
- Be cautious when giving any AI agent access to accounts or the ability to take actions.
What are the Claude AI plans?
Claude offers a free plan with limited usage, Pro and Max plans for individuals who need more usage and features, and Team and Enterprise plans for organisations, with admin controls and data protections. Developers pay separately for API usage by tokens.
Also asked as: what are claude ai plans
Paid plans add higher usage limits, access to more models and features, and tools such as Claude Code for software development. Plan names, limits and features change, so check the official pricing page for current details in your country. Whether Pro is worth it depends on how often you hit free limits and whether you need its extra features; try the free plan for a week with your real tasks first.
Does Claude AI have an app?
Yes. Claude is available on the web at claude.ai, as desktop apps for macOS and Windows, and as mobile apps for iOS and Android. Developers also use Claude Code in the terminal and IDEs, and the API.
Install the desktop app from Anthropic's official download page and the mobile apps from the App Store or Google Play, avoiding look-alike apps from other publishers. Your conversations and projects sync across devices when you sign in with the same account. The desktop app adds features such as connecting local tools and files, depending on settings and plan.
What are Claude AI skills?
Skills are folders of instructions, scripts and resources that Claude can load when relevant to a task, such as creating spreadsheets, following a company's brand guidelines, or running a team's review checklist. Anthropic introduced Agent Skills in 2025.
Claude reads only a short description of each skill until it needs one, then loads the full instructions, which keeps context efficient. Skills work across Claude's apps, Claude Code and the API. Organisations can create custom skills to package their own workflows and share them with teams. As with any extension, use skills from trusted sources, since they can contain code that runs in Claude's environment.
Can Claude AI make videos?
Claude does not generate video files directly the way dedicated video models do. It can write video scripts, storyboards, shot lists and captions, analyse images and documents, and write code that produces animations or edits video.
For example, Claude can write HTML and CSS or JavaScript animations, code for animation libraries, or Python scripts using ffmpeg to cut and assemble clips, which you then run to produce videos. For AI-generated footage, use dedicated video generation tools and let Claude help plan prompts and scripts. Capabilities evolve, so check Anthropic's announcements for new media features.
Does Cursor AI use Claude?
Yes. Cursor, the AI code editor, lets users choose among models from several providers, and Claude models are among the options and widely used for coding in it. Cursor also has its own models for some features.
Model availability in Cursor depends on your Cursor plan and settings, and Cursor's documentation lists the current models. Many developers pick Claude for complex coding tasks, refactoring and agent mode, while using faster models for quick edits. Anthropic also offers its own coding tool, Claude Code, which runs in the terminal and integrates with editors such as VS Code and JetBrains IDEs.
