A free interactive tool

Every app has a job.
Map yours.

Walk the four layers of the PKM Stack — Identity, Actions, Ideas, and Information — and name the app you’ve hired for every job to be done. Spot the gaps, see the overlaps, and leave with a personalized stack diagram you can export as a PDF, Obsidian markdown, or a ready-to-open Obsidian canvas.

Free. No account. Your data stays in your browser.

The value isn’t the apps. It’s the flow between them.

A PKM system isn’t one app — it’s a stack of tools, each hired for a different job. What makes it work isn’t any single app; it’s how easily information moves between them. Every hand-off is a seam where things can get stuck: captured in the wrong place, siloed in an app you never reopen, impossible to find when you finally need it.

Flows in

Capture lands in the right layer — not stuck in an inbox you never clear.

Flows between

Notes move from Ideas to Actions to Information without copy-paste or dead ends.

Flows back out

You can find and reuse what you saved the moment it’s relevant.

Mapping your stack shows you where information flows freely — and where it snags. That’s where you fix your system.

How it works

Step 1
Walk the stack

Move through the five layers one at a time. For each job to be done — book notes, projects, journaling — pick the app that owns it. Add jobs we missed, drop the ones that aren't yours.

Step 2
See your stack

Get a color-coded diagram of your whole system: which apps are the workhorses, where jobs overlap, and which jobs have no home at all.

Step 3
Take it with you

Export your stack as a PDF, an Obsidian markdown note, or a real Obsidian .canvas file you can drop into your vault and keep refining.
