How Memolok compares to ADRs, decision logs, and wikis
Memolok is ADRs on steroids: the same discipline, structured, and generalized to any decision an organization or its AI agents need to remember why, not just the ones that touch a codebase. Here is exactly what changes against each tool you might already be using.

Architecture Decision Records (ADRs)
Good discipline, narrow reach. Software teams have been writing architecture decision records for years: one short Markdown file per decision, committed alongside the code, with a title, a status, the context, the decision, and its consequences. It's cheap, it lives next to the work, and it uses the same review process as everything else, so the why becomes a first-class artifact instead of a thing everyone is supposed to remember.
If you already write ADRs, keep writing them: you're already ahead of the curve. What runs out isn't the discipline, it's the format. Most decisions aren't about code, so they have no repository to live beside, and go unrecorded. A file has no status you can query: it can be marked superseded, but nothing walks the chain for you, and nothing stops an old file being read as current by someone who found it through search. Nothing records what was expected, so there's nothing to check the outcome against later. A deferral is a paragraph, if it's anywhere at all. And nobody is accountable in a way a machine can read: who framed it, who committed, who was consulted, all of it collapses into a git blame.
Memolok extends the same discipline to every kind of decision, with a status, a supersession chain, a committed expectation, and who decided it, attached to each one.
Decision logs and trackers
A step up from nothing, not a structure. A spreadsheet, a decisions.md file, or a ticket labeled "decisions" is somewhere to log what was chosen and when. What it doesn't give you is shape. Every row is free text, so nothing distinguishes a rejected alternative from a footnote, an expectation from a hope, or a deliberate deferral from a row nobody got around to. Two rows can quietly disagree about the same topic, and nothing in the sheet says which one is currently in force.
A Memolok Decision Ledger (MDL) is not a decision log, despite the similar name. Every Memolok Decision Record inside it has the same six parts every time: the need, the alternatives and what ruled them out, the premises, the commitment, the expected outcome, and what was left open. That structure is what makes a record queryable rather than just searchable, and what makes supersession a fact the ledger tracks rather than a comment someone has to remember to leave. See the glossary for the full definitions of MDR and MDL.
Notion and Confluence
Good for drafting, honest about nothing. Wikis and shared docs are where most organizations keep this material, and they're good at some things: drafting together, linking freely, reading well. What they're not good at is staying honest about status. The current page is whatever someone last edited, and even its version history rarely says why a change was made, only that it happened. Two colleagues can be reading the same page and trusting it for different reasons, neither of which the page itself can confirm.
Pointing an AI assistant at a wiki gets you plausible prose, not an answer. See the Decision Intelligence hub for the full argument on why a structured record answers a different class of question than a document ever can.
LLM memory
Useful for one conversation, not built to be shared or sealed. Model memory keeps what you told it, and self-overwrites as new information arrives, with nothing that says whether a fact is still current or something has since replaced it. It's built around one person's conversation, not a team's shared account of what was decided.
A Memolok Decision Record is different in kind: sealed once it's made, shared across a team, and structured enough to enumerate what was decided, what else was considered, and what's still open. Better model memory makes an assistant more useful in the moment. It doesn't give an organization a queryable account of what it decided and why. See the Decision Intelligence hub for the full argument.
Governance and policy tools
Good at enforcing a rule, blind to why it exists. This is a different kind of comparison than the checklist above: a governance or policy tool isn't a place to record a decision, it's a place decisions get enforced. A different category shows up here too: rules engines and policy platforms that decide or enforce at machine speed, an exception granted, a discount override, a threshold crossed. What they give you is a trace that the rule ran. What they don't give you is why the rule exists: what alternatives were considered when it was set, what was expected to follow, or whether anyone decided it at all rather than letting it accrete.
A governance trace and a Memolok Decision Record answer different questions. The trace tells you the policy executed. The record tells you why the policy exists in the first place, an entirely ordinary decision, captured the same way any other decision is. See Context engineering for the fuller picture of where a Decision Record fits.
Ontology and semantic layers
Defines what your terms mean, not what your organization decided. Like the governance comparison above, this is a different kind of tool than the checklist covers: a semantic layer or ontology defines what "revenue" or "active user" refers to, so an agent stops guessing about vocabulary. It's forward-looking, the same shape as a dashboard or analytics platform, but aimed at meaning instead of data.
A Memolok Decision Record answers a different question: not what a term means, but what your organization chose, why, and what it expected to happen. Most organizations that need one need the other too. See the Decision Intelligence hub for the full argument.
Memolok sits above these tools, not instead of them
None of this is an argument to stop using ADRs, trackers, wikis, or docs. They're where work gets planned, drafted, and shared, and Memolok isn't trying to replace them. It's the layer above all of them: the one place that can tell you, honestly, whether a decision still stands.

Common questions
How is a Memolok Decision Record different from an Architecture Decision Record (ADR)?
Architecture Decision Records inspired the idea but stayed unstructured and software-only. Memolok generalizes the same discipline, a Decision Record, to any decision an organization or its AI agents need to remember why.
Isn't a decision log or tracker basically the same thing?
A decision log is free text: every row can be a different shape, so nothing distinguishes a rejected alternative from a footnote, or a deliberate deferral from a row nobody got around to. A Memolok Decision Record has the same six parts every time, which is what makes it queryable rather than just searchable.
Doesn't my AI already remember this?
Model memory is built for one person's conversation and self-overwrites as new information arrives, with no way to tell whether a fact is still current. A Memolok Decision Record is shared across a team, sealed once it's made, and structured enough to enumerate what was decided, what else was considered, and what's still open.
Isn't this the same as a semantic layer or ontology?
A semantic layer or ontology defines what your terms mean, not what your organization decided or why. A Memolok Decision Record holds no data about vocabulary, it holds the reasoning behind a choice that's already been made.
