Claude

What is Claude?

Claude is an AI assistant built by Anthropic, a company focused on AI safety research. It looks like other chat assistants: you write a message, it answers. The difference shows in the details. Claude is known for reading very long material carefully, following detailed instructions and writing in a way that feels less like a template. Developers also rate it highly for programming, and Anthropic offers Claude Code, a coding agent that works directly in your projects.

Key features

• Long context. Paste a long report, a contract or several files at once and ask questions across all of them. Claude keeps the details in view instead of losing the thread halfway through.
• File analysis. Upload PDFs, spreadsheets, text files and images. Claude can extract tables, compare versions and summarise findings.
• Artifacts. Documents, code, charts and small interactive apps open in a side panel where you can view, edit and reuse them.
• Projects. Keep reference files and custom instructions together so every new chat in the project starts with the right context.
• Web search and research. Claude can look things up on the web and cite sources, and run longer research across many pages.
• Connectors. Link tools such as Google Drive or other work apps so Claude can use their content in answers.

How to get started

1. Open claude.ai or install the desktop or mobile app.
2. Sign up with an email or a Google account.
3. Upload a document you actually need to work with and ask: “Summarise the key points and list anything that needs a decision from me.”
4. Create a Project for recurring work, add your reference files and write instructions about tone and format.
5. Check the privacy settings and decide whether your chats may be used to improve the models.

Who Claude is for

Claude fits people who work with a lot of text: lawyers and analysts reading long documents, writers and marketers who want drafts that need less editing, researchers comparing sources, and developers who want help with real codebases. It’s also a good choice for teams that care about careful, well-reasoned answers more than flashy extras.

Tips to get more from Claude

• Structure your request. Put reference material first, then the task, then the format you want. Claude follows clear instructions closely.
• Ask it to quote. When accuracy matters, ask Claude to quote the exact passages from your document that support each point.
• Use Projects for style. Add two or three examples of your best writing to a Project and ask for new texts in the same voice.
• Iterate on code in small steps. Ask for a plan, then implement piece by piece, testing as you go.
• Check edits. Paste the original and the edited version into the free text compare tool to review every change.

Claude vs alternatives

ChatGPT has more built-in media features, such as image generation and a large store of custom GPTs. Gemini works best if your files live in Google Drive and your mail in Gmail. Perplexity is a better fit when you mainly need sourced answers to research questions. For programming, Claude Code brings Claude into your terminal and editor so it can read and change a whole project.

Is Claude worth it?

If your work involves long documents, careful writing or code, Claude is one of the strongest assistants available, and the free plan is enough to find out whether its style suits you. Heavy users usually hit the free limits and move to a paid plan. The best way to decide is to give Claude and one alternative the same real task from your week and compare the results side by side.

Pair Claude with Holsha’s free utilities: the word counter checks the length and reading time of drafts, and the JSON formatter validates structured output before you use it in code. See all assistants in the AI tools catalog.
