The basics

What evergreen notes actually are

Evergreen notes are notes written and organized to evolve, contribute, and accumulate over years, across many projects. The term comes from Andy Matuschak, a researcher and interface designer, who articulated the practice in his public working notes. The contrast is with transient notes: meeting notes, lecture notes, the scratch pages that serve one moment and then expire. Most note-taking produces transient notes and calls the resulting pile a knowledge base. Evergreen notes are the deliberate alternative: each note is a small, durable statement of one idea, written carefully enough that future work can build on it instead of restating it.
Matuschak worked on iOS at Apple and led research and development at Khan Academy before becoming an independent researcher studying tools for thought. His site, notes.andymatuschak.org, is both the argument and the demonstration: a public, browsable network of his own evergreen notes, where the note titled "Evergreen notes" links out to the principles, objections, and neighboring ideas that define the practice. The practice is not a product or a book; it is a working method he developed for his own research and documented in the open.
The practice in motion looks like this. When you read, or work through a problem, you do not stop at taking notes on the material. You look for the durable idea inside it, write that idea as its own note in your own words, give it a title shaped like a claim, and link it to the existing notes it extends or contradicts. Old notes get revised when new thinking presses on them rather than being left as a frozen record. Writing is the mechanism, not the by-product: Matuschak treats note-writing as a fundamental unit of knowledge work, the place where thinking actually happens rather than a container for its results.
The payoff is accumulation. Because each note is about a concept rather than a project, it outlives the project that produced it. A note written while preparing one essay feeds a talk two years later and a larger piece after that, because it was never filed under the essay; it was linked into your thinking about the concept. Project-siloed notes become archaeology the day the project ends. Evergreen notes stay in circulation. That is what "evergreen" means here: not that a note never changes, but that it stays alive, revised and re-linked as your understanding grows.
The practice descends openly from Niklas Luhmann's Zettelkasten, and Matuschak says so. The differences are of emphasis rather than mechanics. Zettelkasten, at least as commonly received, centers the apparatus: permanent identifiers, the slip box, an accumulating reference network aimed at publication. Evergreen notes center the writing. The note exists to develop an idea, the orientation is concept-first rather than source-first, and the test of the system is whether your ideas are actually improving, not whether the archive is growing. There is no numbering scheme to maintain and no required tooling; the discipline lives entirely in how the notes are written and connected.

Who it is for

Who evergreen notes are for

Researchers and independent thinkers

Anyone whose real work is developing ideas over years is the native audience. A research program is exactly the situation evergreen notes were built for: questions that outlive any single paper, concepts that deepen across a decade, and the recurring need to pick up a thread of thinking months after you put it down. The notes become the durable substrate of the research, so each project starts from the accumulated thinking of every previous one rather than from a blank page.

Writers building a body of work

Essayists, newsletter writers, and non-fiction authors return to the same themes across pieces, whether they plan to or not. Evergreen notes make the return deliberate. The concept note written for one essay is waiting, already linked to its neighbors, when a later piece approaches the same ground from a new angle. Over years, the note collection becomes the writer's actual voice: the set of claims they have worked out carefully, ready to be composed into whatever the next piece needs.

Engineers and designers building a theory of their craft

Professional judgment is made of durable ideas: why code reviews fail, what makes an interface calm, when abstraction is worth its cost. Most practitioners hold these ideas vaguely, re-deriving them with each project. Writing them as evergreen notes turns tacit judgment into explicit, linkable claims that sharpen each time a project tests them. The note contradicted by this quarter's experience gets revised, and the revision is the professional growth, made visible.

Anyone whose notes die at the end of the meeting

Transient notes are not the enemy; they are feedstock. The meeting notes, lecture notes, and daily pages keep their role as capture surfaces. The evergreen practice adds one habit on top: when a transient page contains an idea with a longer life than the meeting, that idea gets promoted into its own note, in your own words, linked into the network. The transient page can then expire in peace, and the one durable thought it contained survives it.

The four principles

What makes a note evergreen

Atomic: one concept per note
Each note is about exactly one concept, expressed as completely as you can manage. Atomicity gives the concept clear edges: it can be linked to precisely, revised without collateral damage, and combined with other notes in arrangements you did not foresee when you wrote it. A note holding three ideas can only be referenced vaguely, and vague references do not compound. The constraint feels inefficient in the moment and pays for itself every time a later note wants to build on exactly one of those three ideas.
Concept-oriented, not source-oriented
The note is about the idea, not about the book, paper, or meeting where you met it. This is the sharpest break from ordinary practice, in which notes are filed by source and the same concept sits fragmented across a dozen book summaries. Organize by concept, and your tenth book on habit formation deepens notes that nine previous books already built, forcing the new material to confront what you already believe. Organize by source, and every book starts from zero.
Densely linked
Every new note gets linked to the existing notes it extends, supports, or contradicts, and finding those links means actually reading old notes with the new idea in hand. The linking is not bookkeeping; it is the moment of thought. Noticing that a new claim collides with something you wrote last year is precisely the kind of noticing the practice exists to produce. A collection with few links is a pile, however well-written each individual note may be, and piles do not accumulate insight.
Titles that read like claims
Matuschak describes note titles as being like APIs. A title such as "Evergreen notes facilitate insight accumulation" is a claim: it states what the note argues, so a later note can invoke the whole concept by reference, the way a well-named function invokes its implementation without exposing its internals. Titles like "Notes on productivity" name a topic rather than a thought, and cannot be invoked. Writing the claim-shaped title is hard because it forces you to decide what the note actually asserts, which is the point.

Common mistakes

Where evergreen notes go wrong (and the fix)

Collecting instead of writing
Saving articles, clipping quotes, and importing highlights produces a reference library, not evergreen notes. Evergreen notes are written, in your own words, as your own claims; collected material is at best raw input to that writing. The fix: for each saved item that matters, write the one durable idea it gave you as its own note. The saved source can stay attached as evidence, but the note is the asset.
Organizing by source
A folder per book, a page per course, a section per meeting: source-oriented structure quietly rebuilds transient note-taking inside a system that was meant to escape it. Concepts end up scattered across the sources that mentioned them. The fix: let sources be metadata and concepts be the structure. When two books teach you about the same idea, both should strengthen the same note.
Writing notes that never link
This is the failure that claims most attempts. The honest critique of evergreen notes is that the practice demands sustained writing discipline, and when the linking step gets skipped for a busy month, the collection collapses into an unlinked pile that no longer talks to itself. The fix: make linking part of writing, not a separate chore, and accept help. Tools that surface related notes while you write lower the cost of the step that discipline alone tends to drop first.
Titles that say nothing
A collection full of titles like "Thoughts on motivation" and "Meeting with Sam" cannot be built upon, because no later note can invoke a vague title as a building block. The claim-shaped title is not cosmetic; it is what makes the note usable as an API. The fix: before saving a note, ask what it actually asserts, and put that assertion in the title. If the note asserts nothing, it is probably a transient note, which is fine, but it is not evergreen.

How Mindly fits

How to apply evergreen notes in Mindly

The honest report on evergreen notes is that the practice has two halves, and they fail at different rates. The writing half (one concept, your own words, a claim for a title) is craft, and it remains craft in any tool; no software can do it for you, and Mindly does not pretend to. The linking and retrieval half (remembering what you already wrote, finding the notes a new idea should connect to, keeping the network navigable as it grows) is labor, and it is where most attempts actually die, usually in the busy month when the discipline lapses and new notes pile up unlinked. Mindly automates that second half. Auto-connections surface related items as you write or save something new, so the link between a fresh thought and a note from last year gets proposed even when you have forgotten the older note exists. Semantic search matches on meaning rather than exact words, which is what concept-oriented retrieval requires: the note titled with your claim about attention surfaces when you search for focus, distraction, or deep work. The mind map shows the network itself, so you can see where thinking is clustering and where notes sit orphaned. The result is that the web of ideas keeps forming through the weeks when your discipline lapses, and the practice can survive its bad months, which is precisely when unassisted versions collapse. What Mindly does not change is the writing. Matuschak would likely point out that tools are not the bottleneck, thinking is, and he is right: an evergreen note exists only once you have written one concept in your own words and given it a title that makes a claim. Mindly's promise is narrower and, we think, honest: given the same amount of writing, more of it stays connected, retrievable, and alive. If a fully manual practice appeals to you, a plain-text tool like Obsidian is closer to Matuschak's own setup, and his site documents the method better than any summary can. If you want the accumulation without gambling everything on unbroken discipline, Mindly is built for exactly that gap.

Common questions

Evergreen Notes, answered

Who came up with evergreen notes?

Andy Matuschak, a researcher and interface designer who previously worked on iOS at Apple and led research and development at Khan Academy. He articulated the practice in his public working notes at notes.andymatuschak.org, which serve as a live demonstration of the method. He describes it as descending from Niklas Luhmann's Zettelkasten tradition.

What makes a note evergreen rather than transient?

An evergreen note is written to be reused: one concept, in your own words, densely linked to related notes, with a title that states a claim. A transient note serves a single moment (a meeting, a lecture, a day) and expires with it. The distinction is about intent and construction, not topic; the same meeting can produce a transient page and one evergreen idea promoted out of it.

How are evergreen notes different from Zettelkasten?

Evergreen notes descend from Zettelkasten and share its core: atomic notes, your own words, dense links. The emphasis differs. Zettelkasten as commonly practiced centers the apparatus (permanent identifiers, the slip box, a reference network aimed at publication), while Matuschak's practice centers writing as thinking, orients notes around concepts rather than sources, and drops the numbering machinery. If Zettelkasten is a system you maintain, evergreen notes are closer to a standard you hold your writing to.

What does "note titles are like APIs" mean?

It is Matuschak's phrase for claim-shaped titles. A title like "Evergreen notes facilitate insight accumulation" packages the whole concept behind a stable name, so later notes can reference it the way code calls a well-named function, without re-explaining the internals. Topic titles like "Notes on habits" cannot be invoked this way, which is why the practice treats title-writing as real intellectual work.

Do meeting notes and daily notes still have a place?

Yes. Transient notes are the capture surface, and Matuschak keeps them too. The practice adds one habit: when a transient page contains an idea with a longer life than the meeting, promote it into its own evergreen note and link it into the network. The transient page can then expire without taking the durable idea down with it.

How many evergreen notes do I need before the practice pays off?

Fewer than you might fear, but more than a weekend produces. The compounding starts once new notes regularly find existing notes to link to, which for most people happens somewhere in the first several dozen well-linked notes. The real threshold is behavioral rather than numerical: the practice pays off when reading old notes while writing new ones has become the normal way you work.

Can AI write evergreen notes for me?

No, and this is worth being plain about. The value of an evergreen note comes from you articulating a concept in your own words; a generated note would be a summary wearing the wrong clothes. What AI can honestly do is the surrounding labor: surfacing the related notes a new idea should link to, retrieving concepts by meaning rather than keyword, and keeping the network visible. That is the half Mindly automates. The writing half stays yours.
