Claude Projects is a feature that lets you create an AI workspace with persistent contextual memory – where Claude always understands who you are, what you're doing, and what style of response you want, without needing to explain yourself every time a new conversation begins.
Instead of starting from scratch in every conversation, a Claude Project saves all your guidelines, preferred styles, and references. The result: Claude acts as a personal assistant trained specifically for your role, domain, and standards—consistent from the first conversation to the hundredth.
How to set up a Project in Claude more effectively
Step 1: Create a new project and add instructions for the project.
From Claude's main interface, look at the menu bar on the left and click on Projects . On the project management screen that appears, click the New project button in the upper right corner to start creating your own writing space.
After you have created your project, find it in the project menu.
Step 2: Set up system instructions (Set project instructions)
The AI navigation command configuration window will appear. Copy the professional story writing rules and paste them into the input field:
- Input content: Fill in the details for # Role & Writing Style , # Strict Storywriting Rules (rules for using hyphens in dialogue
-, exploring inner thoughts, adjusting pacing, and blocking AI clichés), and # Processing Procedure .
To complete: After pasting all the instructions, move your mouse to the bottom right corner and click the Save instructions button.
Step 3: Open the data content addition tool.
Once you've returned to the main interface of your comic project (for example, the project named TipsMakewrite ), look at the information management panel in the upper right corner. In the Files section , click the plus sign (+) , a dropdown menu will appear, select the second option, Add text content.
If you choose the Files option, follow the instructions below.
Go to the Files section in Project → click the "Add" button next to it. Select the type of document you want to upload:
Claude reads and memorizes the contents of these files – he can quote, compare, or apply information from the documents when responding in the Project.
Step 4: Import character profiles and plot outlines.
The Add text content dialog box will appear; proceed to fill in the core information to serve as "background memory" for the AI to write the story:
- Title field: Give the data a clear identifying name, for example:
Ho-so-nhan-vat-va-Cot-truyen-cot-loi. - Content Box: Paste the entire detailed information form, including the specific profile of each main character, the plot development stages (Beginning, Development, Climax/Twist, Ending), and the article formatting guidelines.
- Save: Review the entire document, then click the Add Content button in the bottom right corner to complete the data loading.
Now your story writing project is ready to receive commands. Claude will automatically adhere to your saved character profiles and literary style guidelines without you having to repeat the process in each chat session.
Step 5 - Start using Project
Once you've set up the Instructions and Files, click the chat box in the Project and start asking questions. Claude will respond based on the entire configured context – no introductions or explanations are needed.
How to write the most effective instructions in Claude Projects.
Instructions are the most important part of a project – they determine whether Claude truly "understands" you. Most users write instructions that are too short and vague, resulting in nothing more than a casual chat.
- Be specific instead of generalizing. "Write concisely" isn't enough—say "each answer no more than 200 words, no table of contents." "Write professionally" isn't enough—say "use the language of the Harvard Business Review, no exclamations."
- Provide an example of the desired output. Paste a sample essay you like into the Instructions and add, "Write in a similar style and length to the sample essay below." This is the most effective way for Claude to learn your style.
- Clearly define what not to do. Sometimes saying "don't do X" is more effective than "do Y." For example: "Never begin an answer with 'Of course!' or 'Absolutely!'", "Don't suggest expert consultation at the end of every answer."
- Update the instructions periodically. The project isn't a one-time configuration. After a few weeks of use, you'll notice areas where Claude isn't quite right – add to the instructions for continuous improvement.
Who is Claude Projects suitable for?
Claude Projects is more than just a tool for developers – it's a feature of real value to a wide range of users.
- For content writers and journalists: Create a separate project for each newsroom or brand you write for, with a style guide, tone of voice, and a list of topics to avoid already saved. Each time he writes an article, Claude already knows the standards for each place without needing to repeat them.
- For researchers and academics: Upload research papers, documents, and data to the Project – then ask Claude to compare, summarize, or find contradictions between the sources. Claude will respond based on the specific documents you provide, not information from general training data.
- For marketing and sales teams: Create a project containing product information, customer personas, and common objections – use this to draft emails, pitch decks, or FAQ answers faster while maintaining consistency with the brand message.
- For developers: Download the entire codebase or connect to the GitHub repository - Claude understands your project structure, names variables according to your conventions, and avoids suggesting libraries you don't want to use.
Frequently Asked Questions
How long does Claude Projects retain context?
- Instructions and files in the Project are saved permanently until you edit or delete them. Conversation history in the Project is also saved and Claude can refer to it when needed.
Is it possible to share the project with others?
- Project sharing is available in the Claude Team and Enterprise plans. In personal accounts, projects can only be used by the account owner.
Is there a limit to the number of files that can be uploaded?
- Limits depend on the subscription plan and the total context window size. Pro accounts have significantly higher limits than free plans. Prioritize uploading only truly necessary and directly relevant documents to avoid wasting context.
How is Claude Projects different from a regular System Prompt?
- The System Prompt in the API is a technical-level configuration for developers, applied when calling the API. Claude Projects is the end-user interface, requiring no programming knowledge, storing both instructions and files, and operating across multiple conversations within the same workspace.
