The basics
What is Claude?
Claude is the AI chat by Anthropic, a US company with a particular focus on AI safety. It works just like ChatGPT: type a question, get an answer – in the browser or via desktop and mobile app.
Claude has earned its reputation with particularly careful, well-structured answers. It plays to its strengths above all with long texts and large documents: entire contracts or reports can be uploaded, summarized and reviewed in one go. Its German is very good too – and if you specify a certain tone or style, you get texts that reliably stick to it.
That is why Claude is popular wherever text quality matters – and for programming. Like every AI tool, it remains a tool, not an oracle: professional control over facts and results stays with you.
Typical use cases
What is Claude best suited for?
Reviewing long documents
Contracts, reports, minutes: Claude summarizes entire documents in one go, answers questions about them and finds the relevant passages.
Demanding texts
Writing and revising at a high level – from customer emails to specialist articles. Claude reliably sticks to a given tone and style.
Working in a structured way
Outlines, concepts, decision papers: Claude brings order to loose thoughts and delivers cleanly structured results.
Programming help
Explaining code, finding bugs, writing scripts and functions – for programming, Claude is among the most popular AI tools.
Analyses from files
Evaluating uploaded files: putting figures into context, spotting patterns, extracting key statements – without you having to work through everything yourself.
Second opinion
Used alongside ChatGPT, Claude often offers a different perspective on the same task – ideal for cross-checking and improving drafts.
Claude is less suitable if you want to generate images or search the classic way with a results list: there is no image generator, and the tool does not replace a search engine either. For images, see our guide to Midjourney, for research with source citations the one on Perplexity.
The most important question
What is free – and what does paying get you?
Permanently free with Sonnet
With a free account you chat permanently with the standard model Sonnet – often perfectly sufficient for everyday questions and text work:
- Chat with the standard model Sonnet, including web search
- File uploads & voice mode
- Web, desktop app and smartphone app
- Usage limit per rolling 5-hour window – fine for everyday use
- Not included: the coding tool Claude Code
More usage, strongest model
Claude Pro (around 20 US dollars/month, approx. 17 US dollars with annual billing) is worth it as soon as you work with the tool daily:
- At least 5× as much usage per time window
- Access to the strongest model Opus
- Additional tools such as Claude Code for programming
- Max tiers for heavy users
- Team plans for use across your business
Our recommendation for beginners: start for free and work seriously with the tool for two weeks. If you regularly hit the 5-hour limit or need Claude Code, Pro is the logical next step. Prices and limits change constantly – what counts are the current details at Anthropic (this page reflects September 2026).
Getting started
From beginner to pro in four steps.
-
Create an account
Register with Claude for free – in the browser or via app. Start with a real task from your working day instead of gimmicks.
-
Upload a document
Play to its greatest strength: upload a long report or contract and have it summarized and reviewed – in one go.
-
Set the tone
Describe your audience, tone and style – Claude sticks to them reliably. Refine in dialogue: “Shorter.” “More formal.” “As an outline.”
-
Check & adopt
Always double-check facts, figures and legal statements. You remain responsible – Claude is your most careful assistant, not your replacement.
A note on privacy: as with all AI chats – do not enter personal customer data or trade secrets into freely worded chats. Anthropic does emphasize its focus on safety, and for teams there are business plans – when in doubt, the rule still applies: anonymize first, then ask.
Frequently asked questions
Frequently asked questions about Claude.
Is Claude free?
Yes. With a free account you can use Claude permanently – with the standard model Sonnet, including web search, file uploads and voice mode. Usage is limited per rolling 5-hour window: for everyday use that is usually enough, but with intensive work the limit is quickly reached. The coding tool Claude Code is not included in the free plan.
How is Claude different from ChatGPT?
The way you use them is practically identical: type a question, get an answer. Claude has earned a reputation for delivering particularly careful and well-structured answers, is very strong with long texts and large documents, and reliably sticks to a given tone and style. In return, there is no image generator and no classic search engine with a results list. Many people use both tools side by side.
How much does Claude Pro cost?
Claude Pro costs around 20 US dollars per month, less with annual billing (approx. 17 US dollars/month). In return you get at least five times as much usage per time window, access to the strongest model Opus and additional tools such as Claude Code. For heavy users there are Max tiers above that, plus team plans. You will find current prices directly at Anthropic (as of September 2026).
Does Claude speak German?
Yes, very well. You can write entirely in German and receive German answers of high linguistic quality. Claude also drafts and revises longer German texts reliably – including a specified tone.
What is Claude particularly worth using for?
Anywhere care and text quality matter: summarizing and reviewing long documents such as contracts or reports in one go, writing and revising demanding texts, structuring outlines and concepts, supporting you with programming, and pulling analyses from uploaded files. And as a second opinion alongside ChatGPT, Claude often delivers the decisive different perspective.
