Key takeaways
- Claude is an AI assistant made by Anthropic, available on the web, as desktop and mobile apps, through an API for developers, and as Claude Code for software engineering.
- Models come in tiers — a most-capable tier, a balanced tier and a fast, low-cost tier. Names and prices change, so check anthropic.com.
- It is especially strong with long documents, careful writing, analysis, coding and detailed instructions — including in Arabic.
- Use a business or team plan for company data, never paste passwords, and always check the output before it leaves your desk.
What is Claude?
Claude is a family of large language models built by Anthropic, an AI company based in the United States. You talk to it in plain language — type a question, paste a document, upload a file — and it replies with text, tables, code or structured documents. Like other AI assistants, it predicts useful responses based on patterns learned from large amounts of text; it does not “know” your business unless you give it the context.
Where you can use it
- claude.ai — the chat interface in any browser, plus desktop apps for Windows and macOS and mobile apps for iOS and Android. This is where most staff will start.
- The API — for developers who want to build Claude into their own systems: a support inbox that drafts replies, an internal tool that reads invoices, or a chatbot on your website.
- Claude Code — a tool for software engineers that works directly in a code project: reading files, making changes, running commands and explaining existing code.
Model tiers in plain terms
Anthropic offers several models at once, grouped into tiers. The exact version numbers change regularly, but the pattern has stayed consistent:
- Opus — the most capable tier, for complex reasoning, difficult code and long, demanding tasks.
- Sonnet — the balanced tier, a strong everyday choice that mixes quality and speed.
- Haiku — the fast, low-cost tier, ideal for high-volume work such as classifying emails or extracting fields.
Model names, limits and prices change, so check anthropic.com for the current line-up. If you are using the API, costs are measured in tokens — our guide to AI tokens explains what that means for your bill.
What Claude does well
- Long documents — it can read lengthy contracts, reports or manuals in one go and answer questions about them.
- Writing — clear drafts, rewrites in a different tone, and translations that read naturally.
- Analysis — comparing options, spotting gaps in a proposal, summarising spreadsheets and data.
- Coding — writing, reviewing and explaining code and SQL queries.
- Following detailed instructions — format rules, style guides and step-by-step requirements.
- Arabic — it reads and writes Arabic well, which matters for businesses serving Lebanon and the region.
Features worth knowing
Projects let you group related documents and standing instructions in one place — for example a “Customer replies” project holding your price list, policies and preferred tone, so every chat inside it starts with that context. Claude can also produce artifacts: standalone documents, tables, code or simple web pages shown beside the chat that you can edit, copy or download. Available features vary by plan and change over time.
Business use cases
| Use case | Example | Tip |
|---|---|---|
| Drafting | Proposals, emails, job descriptions, policies | Give a sample of your own writing so the tone matches. |
| Summarising | Key obligations and dates in a supplier contract | Ask it to quote the clause it relies on, then check it. |
| Customer replies | Polite answers to complaints in English or Arabic | Keep a Project with your policies; a human approves before sending. |
| Code | A script, a SQL query or a code review | Test in a safe environment, never directly on production. |
| Data analysis | Trends in a sales export, anomalies in expenses | Remove personal data first and verify key numbers yourself. |
Privacy and safety
An AI assistant is only as safe as the way your team uses it. A few rules cover most of the risk:
- Use a business or team plan for company data. These typically add admin controls and clearer data commitments than personal accounts — read the plan’s data policy before you roll it out.
- Never paste passwords, API keys or banking details into any AI tool.
- Check every output. Claude can be confidently wrong — figures, legal points and facts must be verified by a person.
- Write a short company AI policy stating which tools are approved, what data may be shared and who is accountable for the final result.
The bottom line
Claude is a capable assistant for writing, reading, analysis and code, and the tiered models let you match cost to the job. Start with a few real tasks, compare it with other tools — see our notes on using ChatGPT at work and the wider AI tools landscape — and set clear rules before company data goes in.
