Summary written by us from the video's transcript. The video, and everything in it, is AI Foundations's work.

Learn how to set up and use Claude projects to keep context, files, and custom instructions organized for ongoing work.

Takeaways

  • Projects keep all prompts, files, and conversation history together so Claude retains business context over time.
  • Upload a concise business overview document; it becomes the foundation for accurate, customized advice.
  • Project‑level instructions let you control Claude’s role, output style, and requirement to reference specific files.
  • Claude’s memory within a project automatically captures facts you mention, reducing repetitive input.
  • Large file uploads (e.g., video transcripts) enable RAG searches while consuming only a small portion of context capacity.

Why Use Projects

Claude’s default chat forgets details between sessions, so each new conversation starts with little context. A project acts as a dedicated workspace that stores custom instructions, uploaded documents, and the full conversation history, allowing Claude to retain knowledge over days, weeks, or years.

Creating a New Project

In the Claude UI click **New Project** in the upper‑right corner, give it a clear name (e.g., “Business Strategy Room”) and a short description of its goal. After saving, you’re taken into that project’s view with a header, description, and a prompt bar just like a regular chat.

Organizing Files

The file pane on the right lets you upload PDFs, text files, GitHub repos, or Google Drive docs. Uploaded files stay attached to the project permanently, unlike one‑off uploads in a normal chat. A common starter is a “business overview” document that covers company identity, revenue model, offer stack, team, market position, growth profile, and 90‑day priorities. This base of information lets Claude give tailored advice without re‑explaining your business each time.

Setting Project Instructions

Project‑level instructions override global settings for this workspace only. You can define Claude’s role (e.g., “You are a business strategist”), require it to always reference specific files, and specify output formats such as tables or bullet lists. Instructions can also enforce grounding in real numbers, flag ideas that don’t align with 90‑day priorities, and demand trade‑off analysis. Save the instructions and Claude will apply them to every subsequent reply in that project.

Using Memory and Context

Claude automatically builds a memory of facts you mention within the project (e.g., personal details like pet names). This memory is displayed on the right side and supplements the uploaded files, helping Claude recall earlier statements without re‑typing them.

Advanced Use Cases: RAG and Desktop App

With many large text files—such as 30‑minute YouTube transcripts—Claude can perform Retrieval‑Augmented Generation (RAG) to answer specific questions across all uploads while using only a fraction of the project’s context quota. The Claude desktop app adds co‑work capabilities: tasks are executed and saved directly on your computer, making it ideal for outcome‑focused workflows like content repurposing. Projects on the web can be shared with teams via Claude Teams, whereas desktop projects remain local to one user.
