One distinction people often note between Anthropic (the maker of Claude) and some other AI companies is Anthropic's stated mission: using artificial intelligence for the long-term benefit of humanity, with safety as a core focus.

Claude is built to be helpful, harmless, and honest. In other words, Claude is trained to align with human values and operate transparently.

Claude is conversational, but not in the narrow sense of a chatbot — it's far more. It can process many forms of digital and paper-based information while maintaining a high standard of predictability, reliability, and accuracy. It's efficient at tasks like summarization, search, creative and collaborative writing, Q&A, and coding, to name a few.

Claude is also built to be steerable and collaborative: it can be customized and directed on personality, tone, and behavior.

What Claude excels at

Writing and content creation

  • Collaborate with Claude on social media, email, and complex report tasks.

Research and analysis

  • Explore research from a variety of angles, filter and compile findings, and analyze data to surface valuable insights.

Coding assistance

  • Claude's Opus models are widely regarded as among the most powerful coding models available.
  • Collaborate with Claude to write, debug, and explain code across a variety of programming languages.

Problem solving and reasoning

  • Claude can help with complex thinking, math, strategy, and research.
  • Models like Opus and Sonnet support quick answers when you need speed, and an "extended thinking" mode when you want a more careful, step-by-step approach.
  • Explore the unknown
    • Whether you're learning something new, exploring an unfamiliar topic, or tackling a tough problem, Claude can match your pace and learning style.
    • Learning mode guides your reasoning instead of just handing you the answer, so you build stronger critical thinking skills.

Ways to access Claude

Claude is the same intelligence across a few different "front doors." The best one depends on what you're trying to do.

1) Claude.ai (web, desktop, and mobile)

The main place most people start. Use it for brainstorming, writing, editing, summarizing, and asking questions.

2) Claude Code

If you work with code or files, this is the fastest way to get real work done: edit files directly, run commands, and create commits.

3) Claude in Slack

Great for teams that live in Slack. Chat with Claude from any channel or DM, or mention @Claude in a thread — when connected, Claude can use your Slack context to answer more accurately.

4) Claude for Excel

Best when your work is in spreadsheets: analyze models and assumptions, debug formulas, and update templates across tabs.
