Claude AI — the guide
for the advanced user
Projects, Memory, Artifacts, MCP and System Prompts — everything you need to master Claude.ai without writing a single line of code.
Two separate guides — choose by what you need:
What is Claude?
Claude is a large language model (LLM) from Anthropic — an AI company founded in 2021 by former OpenAI employees, led by Dario and Daniela Amodei. Anthropic's DNA is AI Safety — safe, honest and transparent models.
Claude is considered one of GPT-4o's strongest competitors. In areas like writing code, analyzing documents, and understanding long context — it usually wins.
What sets Claude apart?
- A 1M-token Context Window — almost unlimited. An entire codebase, a book, thousands of messages
- Constitutional AI — Claude is designed to answer honestly, admit mistakes, and explain why it refuses
- Artifacts — creating code, HTML, React, SVG directly from the chat with a real-time Preview
- Analytical honesty — less sycophancy compared to competitors
- Projects + Memory — persistent memory organized by topic

Projects — organized memory for every topic
Projects is claude.ai's most powerful feature. Instead of briefing Claude again in every conversation — you save context, files, and instructions in a single Project that lasts forever.
Think of a Project as a "folder" containing an AI employee who knows who you are, what the project is, and all the relevant files — without you having to repeat yourself.
How to create a Project — step by step
In the side menu on claude.ai, under "Projects" — click the + button to create a new Project.
For example: "Marketing assistant", "Customer analysis", "Website content writing". The name is just for your own organization.
This is the Project's System Prompt. Write here: who Claude is in this context, what the style is, what the boundaries are. This is saved for every conversation within the Project.
PDF, Word, Excel, images, code — Claude will read them and remember the content across all the Project's conversations.
Every new conversation you open from within the Project automatically gets the instructions and files — without copying them again.
Example Project Instructions by use
Create separate Projects for each client, product, or work area. The Context doesn't mix between Projects.
Memory — a Claude that remembers you
Memory lets Claude remember details about you between conversations — even outside Projects. It learns from your conversations and generates automatic "memories".
Two types of memory
Claude identifies important details from conversations (name, profession, preferences) and stores them. You can view and delete them in Settings → Memory.
Tell Claude "remember that..." so it saves specific information. For example: "remember that I work at a B2B SaaS startup."
Memory works at the account level. Project Instructions are specific to a Project. The two work together.
Artifacts — direct creation from the chat
Artifacts is the feature that sets Claude apart from all competitors. Instead of getting code inside the chat — Claude opens a separate Panel with an editor + a real-time preview.
Write "create an Artifact of..." and the Panel will open. Or simply ask for code — Claude decides automatically.
What can you create?
Runs directly in the browser. You can download and use it.
Full State, hooks, useState — everything runs inside the chat.
Infographics, diagrams, logos — exportable at any size.
Easy export, editing, sharing. Suited to reports and work documents.
Tip: improving Artifacts in the conversation
MCP — connect Claude to your tools
MCP (Model Context Protocol) is a protocol that lets Claude communicate directly with external apps — like Google Drive, Notion, GitHub, and more. Instead of copying information manually — Claude reads directly from the source.
Popular MCP servers on claude.ai
How to connect MCP on claude.ai
Sign in to claude.ai → click your name at the top → Settings → Integrations (or Connectors).
Choose the app (Notion, Drive, GitHub...) and click Connect. You'll need to approve permissions.
Now, in a conversation with Claude, you can ask: "Read the Notion page about our project and summarize it."
You can build your own MCP Server that connects Claude to any API — see the API guide for the technical details.
System Prompts — make Claude work for you
A System Prompt is the instruction sent to Claude before every conversation. On claude.ai you can set it in Project Instructions.
