You likely have information scattered everywhere. Half of your ideas live in Apple Notes, your project tracking happens in Notion, and your downloads folder is a mess of unnamed screenshots. Finding exactly what you need takes too much time.

Claude Cowork changes that completely. It acts as an AI agent on your Mac, securely reading your local files and connecting directly to your favorite apps. You can ask it a question, and it will hunt down the answer across your entire system.
Here is how to set it up and build your own searchable AI knowledge base.
To make Claude smart about your specific data, you need to connect it to the places where you actually work.

You have total granular control over what Claude can do. For example, you can set Read-only tools to Always allow. This lets Claude freely search your databases. For Write/delete tools, set them to Needs approval. This ensures Claude cannot create or delete pages without asking you first.
Now that your apps are connected, you can treat Claude like a universal search engine for your brain.
Head back to the Cowork tab and ask a specific question. If you have a massive Notion database for a podcast, you can simply type, "In what episode did we discuss the M4 Mac Studio?"
Claude will search through your Notion workspace, find the correct show notes, and summarize the answer. It even provides a clickable link to open that exact page in Notion.
You can do the exact same thing with Apple Notes. You might ask, "What are the latest five shortcuts added to my Shortcuts Database note?" Claude will read your local Apple Notes and extract exactly what you asked for.
Pro tip: Claude might initially read a note from bottom to top. If you format your notes differently, you can drop a plain text file into your working folder with specific instructions. Tell Claude, "Always look at the top of the note for the newest information." It will read those instructions and format its answers perfectly next time.
Your knowledge base is not just text documents. It includes your files. Claude Cowork can manage your messy desktop or downloads folder completely hands-off.
Claude will look at every single file. If it finds a random screenshot of a website, it will read the text in the image and rename the file to match the website's title. It can even analyze the frames of video files to figure out what the video is about, renaming generic screen recordings to descriptive titles.
Sometimes the information you need is not in your notes. It is out on the web. You can give Claude access to your browser so it can take actions for you.
Claude will open new tabs, search for promo codes, return to your checkout page, and automatically test them until it finds one that works. It is entirely hands-off. You just watch it happen.
You just turned a scattered mess of apps and files into an intelligent, connected system. Instead of spending ten minutes clicking through folders and searching Notion databases, you can just ask Claude to find the answer. Try connecting a few more of your daily tools and see how much time you save.
