Claude Projects can give AI a memory of your business — here's how
Thursday · Actually Useful AI · June 25, 2026 · 5 min read
Most people use Claude the same way every time: open a new chat, explain who they are and what they need, get an answer, close the tab. It works. But it also means you're re-explaining your business from scratch every single session, and Claude is starting from zero every single time.
Claude Projects fixes that. It's the feature that turns Claude from a smart assistant you have to brief repeatedly into something that already knows your context before the conversation starts. Here's how it works and how to set one up this week.
Feature 01: What Claude Projects actually does
A Project is a persistent workspace inside Claude. You create it once, add your instructions and files, and every conversation you start inside that Project automatically has access to everything you've put there. Your tone preferences, your business context, your recurring formats, your client background, all of it is available without you re-pasting anything.
The practical result: your prompts get shorter and your outputs get better. Instead of opening every session with two paragraphs of context, you ask your question and Claude already has what it needs.
Projects also group your conversation history, so everything you've done inside a Project stays organized in one place. One Project for client work. One for content. One for operations. Each stays separate, each remembers its own context.
To set up your first Project:
Open Claude and click "New Project" in the left sidebar.
Name it specifically. "Client Coaching Notes" beats "Work." The more specific the name, the more intentional you'll be about what you add to it.
Write custom instructions — a paragraph or two explaining who you are, what this Project is for, and how you want Claude to behave inside it. This is the most important step.
Upload any files Claude should reference (more on that below).
Start a conversation. Every new conversation inside this Project inherits your instructions and files automatically.
Feature 02: Writing custom instructions that actually work
Custom instructions are a short document that tells Claude what it needs to know before every conversation in this Project. Think of it as the briefing you'd give a new assistant on their first day.
A strong set of instructions covers: who you are and what you do, what this Project is specifically for, tone and style preferences, things Claude should always do, and things Claude should never do.
Here's an example for a business owner who uses Claude for client-facing content:
Start with identity. "I am a business coach working with small business owners and entrepreneurs. My brand is called Execution Expert."
Name the Project's purpose. "This Project is for drafting my weekly email newsletter. Every output should be written for that audience."
Set tone rules. "Write in a warm, direct voice. No coaching jargon. No em-dashes for dramatic effect. No bullet points in the body."
Add standing context. "My newsletter is called The Execution Expert and goes out on Fridays. Word count should be 350-550 words."
Name what to avoid. "Never open with 'Hey!' Never use the words 'journey,' 'hustle,' or 'unlock your potential.'"
The more specific you are here, the less you'll need to explain in individual conversations.
Feature 03: Adding files to your Project knowledge base
Projects support uploaded files that Claude references automatically. Documents, PDFs, text files, CSVs, even images. You can add up to 20 files per Project on Pro and paid plans, at 30MB per file.
What's worth uploading:
Brand and style guides. Anything that governs how your business communicates belongs here. Claude will apply it automatically.
Reference documents you use constantly. Pricing sheets, service descriptions, FAQ documents, intake forms. Upload it once, stop pasting it every session.
Templates and examples. If you have a format you want Claude to follow, show it an example. "Here's a past newsletter issue that represents the right voice" is more useful than three paragraphs describing the voice.
Client or project context. If a Project is dedicated to a specific client or engagement, upload their background document so Claude already knows the situation.
One thing worth knowing: Claude pulls the most relevant content from your files based on what you're asking. It's not reading all 20 files front to back in every conversation. It's finding what's relevant. So organized, specific files outperform one large document that covers everything.
Feature 04: Using one Project for a recurring workflow
The highest-leverage use of Claude Projects for most small business owners is picking one recurring task and building a Project around it. Content creation, client communication, financial tracking, whatever takes the most time and follows the most consistent pattern.
The setup:
Create a Project specifically for that workflow. Name it after the task.
Write instructions that explain the full context of that task — who the output is for, what format it should take, what it should never do.
Upload any reference files that apply. Past examples, style guides, templates.
Run the task inside this Project every time. Over multiple sessions, Claude builds familiarity with your patterns even beyond the files and instructions.
The result is a workflow where you spend less time on setup and more time on the output that actually matters.
Try It This Week
Pick one recurring task that takes you more than 30 minutes a week and requires you to explain context every time you use AI for it. Create a Project for that task, write a set of custom instructions, and run the task inside the Project instead of a regular chat.
Starter prompt to write your own custom instructions:
"I want to create a Claude Project for [task]. Ask me five questions about how I work, what I need Claude to know, and what I always want to avoid. Then draft a set of custom instructions I can paste into the Project."
