Your Markdown, connected and computable.

Live tables, formulas, relationships, and visualizations. All powered by the same local Markdown files. No database. No sync account. Your notes stay .md files you can open in any editor, forever.

WHAT YAMLINK IS

Live tables from your data.

Turn your notes into searchable, sortable, editable tables with !view. Change a value in the table, and Yamlink updates the original MD file. No duplicated data. No separate database.

Formulas to connect your notes

Write formulas directly in Markdown. Reference values from frontmatter, other calculations, linked notes, or entire query results. From simple arithmetic to financial models, your notes can calculate with the information they already contain.

The graph: visualize your connections

Every [[wikilink]] becomes a relationship you can explore. Filter by type, navigate connected notes, and replay how your knowledge graph evolved over time. Your graph grows as you write.

Conduit — the whole vault, in a terminal

Run yamlink and run yout entire vault from the terminal. Browse, edit, query, inspect relationships, and explore your graph through a keyboard-driven interface. The same knowledge system, without needing VS Code.

Intelligence from your own data

Yamlink learns how you structure your notes and suggests fields, relationships, and templates based on patterns in your own vault. No cloud processing. No external AI models. Just intelligence derived from your data.

Know the state of your vault

Find broken links, missing fields, inconsistent structures, and orphaned notes before they become problems. Explore your vault's history and see projections of how its structure and activity may evolve.

Full feature list & guides

Yamlink's local engine powers more than the VS Code extension. Explore your vault through the CLI, Conduit terminal workspace, or HTTP API — all working with the same Markdown files.

FEATURES.md — the complete feature list: graph, block references, query language, chart views, intelligence, Vault Health, and more.
CALCULATIONS.md — the formula engine: same-note and cross-note references, ranges, finance/stats/growth functions, formatting.
CLI.md — the yamlink command: querying, editing, automating, and serving your vault from a terminal.
CONDUIT.md — the full terminal workspace: ten screens, live updates, zero mouse required.
API.md — a quick start for scripting against your vault over a local HTTP server.

What's new this release

0.8.2 — Markdown gets computational.

Inline formulas — calculate directly inside notes using named cells, ranges, conditional logic, dates, statistics, and financial functions. See CALCULATIONS.md.
Connected calculations — reference values across notes, read frontmatter fields, and calculate from live table columns.
Query calculated data — filter, sort, and aggregate computed values across your vault.
New visualizations — line and pie charts join the existing layouts, with support for plotting aggregated values.
Live Note improvements — preview calculated results directly, instead of raw formula syntax.

Fixed

group by on a field holding a single wikilink now groups by the target note's name, not the raw link text.
Frontmatter numbers and booleans now resolve correctly in formulas and queries — they were previously read as plain text.
Dragging a node in the graph no longer shakes the whole graph or leaves it permanently frozen after a few drags.
The graph now assigns a real, stable color to every note type, not just the first 11.

Full list: CHANGELOG.md.

Getting Started

code --install-extension yamlink.yamlink

Open any folder of Markdown files. Add id: something to a note's frontmatter. You have a vault.

If Yamlink is useful to you, a star on GitHub or a review on the VS Code Marketplace genuinely helps.
