Personal knowledge management. Our foundation.
Everything in Tana Outliner is built with the PKM community as our pillars. The graph, our Supertags, and Tana AI.
What is personal knowledge management (PKM)?
PKM is how you capture, organize, and actually use what you learn, instead of letting it disappear into a folder you will never open again. It is the system you build to collect ideas, connect them together, and find what you need when you need it.
In Tana Outliner, PKM lives on top of an AI-powered knowledge graph. Your notes, tasks, projects, and references all stay connected, not scattered across apps or buried in documents.
Why Tana Outliner is built for PKM
Everything in Tana Outliner starts from how knowledge workers actually think. The core building blocks, the graph, supertags, and AI, are designed to handle the full PKM loop:
- Capture ideas, highlights, and tasks in fast daily notes
- Connect them with links, supertags, and fields so context is never lost
- Resurface them through search, queries, and views that bring the right stuff back at the right time
- Think with your notes using AI that understands your graph, not just a flat page
Instead of stitching together a note app, a task manager, and a second brain template, the app gives you one system that grows with your thinking.
Experience the next level of Zettelkasten
The Zettelkasten method is built on two simple ideas: small, atomic notes (one idea each) that link to each other to form a web of thinking. Niklas Luhmann used his 90,000-note slip box to write 70 books and nearly 400 scholarly articles. Not bad for index cards.
In Tana Outliner, every bullet is already a node in your graph, so you get a native Zettelkasten without extra setup. Atomic notes, backlinks, emergent structure, it is just how the app works.
But supertags let you go further than plain links. You can mark a note as a #concept, #source, #claim, or #question, then query and view those notes in different ways. Community templates like Theo's SN(A)CK system give you a Tana Outliner-first Zettelkasten that unifies sources, notes, and creations in one setup.
“Tana Outliner is one of the few knowledge management tools that moves beyond mimicking static text on paper. It takes the computational medium seriously. It gives regular folks access to a set of powerful primitives that previously only developers could touch.”
“I have been using note-taking apps for over a decade. Starting from Notepad, moving to Microsoft Word, Evernote, Gdocs, I have used them all. Then came the era of outliners like Roam, markdown extensible apps like Obsidian, and database-centric Notion. All this while, I felt like something was missing. I wanted a way for data to be easily retrievable, customisable, and yet easily queried intuitively. I found it all in Tana Outliner, I cannot believe I waited so long for something like this.”
Getting things done has never been easier
GTD is David Allen's system for getting everything out of your head and into a system you trust. Five steps: Capture, Clarify, Organize, Reflect, Engage.
Tana Outliner makes GTD feel natural: you capture into daily notes or a quick inbox; clarify with task supertags, fields, and clear next actions; organize using views, filters, and project contexts; reflect through saved searches and weekly review dashboards; engage with tasks that surface alongside the notes and references they depend on.
The nice part? Tasks live right next to your knowledge, not in a separate app you have to keep in sync.
Tana Outliner + PARA = a true second brain
Tiago Forte's PARA method organizes everything by actionability, not topic: Projects, Areas, Resources, Archives. Most actionable first, reference material last.
The graph and supertags map perfectly onto PARA:
- Projects as supertagged nodes with goals, tasks, and deadlines
- Areas as ongoing responsibilities with dashboards of active work
- Resources as articles, books, and notes linked to what they support
- Archives as completed work you can still find when it becomes relevant again
Start from a PARA template, then layer Zettelkasten-style notes and GTD-style execution on top. All in one graph.
What people actually do with Tana Outliner for PKM
Tana Outliner is where all the stuff in your head lands, and then turns into something useful. People use it for:
- Reading and research: Capturing highlights from books, articles, and Readwise, then connecting them to projects and writing
- Thinking and writing: Building idea networks that turn into articles, talks, videos
- Tasks and projects: GTD and custom task systems that keep work moving without a separate todo app
- Life OS, second brain: Combining PARA, GTD, and Zettelkasten into one system that actually works
All of this lives in the same graph. Your PKM is not just a notes library, it is tightly connected to the work you actually do.
