The PARA Method: How to Organize a Second Brain AI Can Read
The PARA method sorts everything you keep into four folders: projects, areas, resources and archives. It files notes by when you will use them, not by topic, which is why it holds up. Here is how it works, how to set it up in an afternoon, and what to change when an AI reads your notes.

The PARA method is a way to organize a second brain into four folders: Projects (work with a deadline), Areas (ongoing responsibilities), Resources (topics you may use later) and Archives (anything inactive). You file each note by where you will use it next, not by subject. It comes from Tiago Forte's Building a Second Brain and takes an afternoon to set up.
PARA is a filing system for digital notes created by Tiago Forte as part of his Building a Second Brain method. It uses four top-level folders, Projects, Areas, Resources and Archives, and sorts each note by how soon you will need it. It works in any app, from Obsidian to Notion to a plain folder.
PARA is the organizing half of the second brain method. The other half, CODE (capture, organize, distill, express), is the workflow; PARA is where the notes land. If the idea of a second brain is new to you, start with what a second brain is and come back.
The reason PARA spread is that it is small. Four folders is a structure you can remember without looking it up, and that is what keeps people filing notes after the first week.
What goes in each PARA folder?
Projects hold work with a goal and an end date, like a product launch. Areas hold responsibilities with no end date, like finances or a client account. Resources hold topics you are interested in but not acting on. Archives hold anything from the other three that is finished or no longer active.

What belongs there
Example
Projects
Short-term work with a goal and a deadline
Q4 webinar launch
Areas
Ongoing responsibilities you maintain
Brand voice, hiring, health
Resources
Topics and reference you may use later
AI tools, copywriting examples
Archives
Inactive items from the other three
Last year's launch notes
The test for Projects versus Areas is one question: does it end? A launch ends. Your brand voice does not. Most filing confusion clears up once that line is sharp.
How is PARA different from organizing notes by topic?
Topic folders ask what a note is about, which has many right answers, so notes get filed in one place and searched for in another. PARA asks when you will use the note, which usually has one answer. That makes filing faster and keeps the notes you need this week in the same small folder.
A note on email subject lines could live under Marketing, Writing or Email if you file by topic. Under PARA it goes in the project you are using it for, or in Resources if you are not using it yet. One home, decided in seconds.
The cost is that topics get split across folders. Search and links handle that better than folders do, which is why PARA pairs well with an app that has good search. We compare the options in the best second brain apps.

How do you set up the PARA method?
Create the four folders. List your active projects and make a subfolder for each. List the areas you are responsible for and do the same. Move everything else into Resources or Archives without sorting it further. Then file new notes as they come in and review the folders once a week.
Make four folders. Number them (1 Projects, 2 Areas, 3 Resources, 4 Archives) so they stay in order.
List active projects. Only work with a real end date. Five to fifteen is normal.
List your areas. The responsibilities you would hand over if you went on leave.
Dump the rest. Old material goes straight to Archives. Do not sort it now; search will find it.
Review weekly. Close finished projects into Archives, and check new notes landed in the right place.
If four folders still feels like a lot on day one, our free second brain template starts smaller, with an inbox, notes, sources and archive, and grows into PARA once you know which projects and areas you return to. The full weekly routine is in our guide to building an AI second brain.
Does the PARA method work when an AI reads your notes?
Yes, with two changes. Folders matter less to an AI than to you, since it searches everything at once, so the archive needs dates or the AI will quote old material as current. And every note needs a source line, so you can check where an answer came from before you rely on it.
PARA was designed for a person scanning folders. An AI tool reading the same notes does not browse; it retrieves passages that match the question. That changes what matters:
Dates beat folders. A two-year-old note in Archives and a note from this week look the same to a search. A date on each note lets the model, and you, tell them apart.
One idea per note. Long notes covering several topics are the main reason AI answers quote the wrong passage.
Sources on every claim. When the model cites a note, the source line lets you check it.
Keep private material out. A separate folder the AI tool cannot read is simpler than remembering what to exclude.
The big three: treating ongoing areas as projects so nothing ever finishes, building deep subfolders inside Resources until filing takes longer than writing, and never archiving, so active folders fill with dead work. The fix for all three is the weekly review: close projects, flatten folders, archive what is done.
A fourth mistake is spending weeks perfecting the structure before writing anything. PARA is meant to be reorganized as your work changes. A rough version you use beats a perfect one you are still designing, and a ten-question retrieval test will tell you sooner than any folder audit whether your notes are findable.
