# Algorithms

Notes on the classics, with complexity in big-O.

## Binary search

Runs in $O(\log n)$ on a sorted array — each step halves the range.

```python

def bsearch(xs, target):

lo, hi = 0, len(xs) - 1

while lo <= hi:

mid = (lo + hi) // 2

if xs[mid] == target:

return mid

if xs[mid] < target:

lo = mid + 1

else:

hi = mid - 1

return -1

```

## Quicksort

Average case $O(n \log n)$, worst case $O(n^2)$ when the pivot is poor.

Randomising the pivot keeps the worst case rare.

## Complexity cheat sheet

| Structure | Lookup | Insert |

|-------------|-----------|-----------|

| Array | $O(1)$ | $O(n)$ |

| Hash map | $O(1)$ | $O(1)$ |

| Balanced BST| $O(\log n)$ | $O(\log n)$ |

See [[Code Snippets]] for more implementations.

What's inside

Built around how writers and developers work.

Marknote is the editor we wished existed: native, keyboard-first, and free of dashboards.

Writing surface

The day-to-day editor — built for keyboard-first writing.

Ctrl+T

Multi-tab editing

Open as many notes as you need across tabs. They come back when you reopen Marknote, and an orange dot marks anything unsaved.

Live preview

Write on the left, watch it render on the right. Switch any time between editor-only, preview-only, and a rich view with math and diagrams.

Slash commands

Type / at the start of a line for instant tables, code blocks, math, diagrams, callouts, dates, and a generated table of contents.

$…$

Inline math in the editor

Write $E=mc^2$ or a $$…$$ block and KaTeX renders the formula in place as you write. Click into the formula and the source comes back so you can edit. Same engine as the preview, so what you see is what ships.

Writer mode

Typewriter scrolling keeps your current line centred on screen. Paragraph focus fades everything except the paragraph you're writing.

Ctrl+Shift+R

Reading mode

A dedicated preview-only state — chrome and editor hide, type goes large and airy, the preview centres at a comfortable reading width. Different from focus mode; this is for reading a long note end-to-end.

No silent overwrites

If a file changes on disk while you have unsaved edits, Marknote asks before doing anything — reload, compare, or keep yours.

Nine editor themes

Marknote Light & Dark, Nord, Solarized, Dracula, and Gruvbox — each tuned so the gutter, selection, active line, and tooltips all feel like one piece, with window materials to match.

Notes that connect

A private knowledge graph that builds itself as you write.

[[…]]

Wiki links + backlinks

Type [[Note]] to link to another note. A live panel shows everything that links back, and an interactive graph maps how every note connects.

Every to-do in one place

A Tasks tab in the sidebar gathers every checkbox across your notes. Click a row to jump to its file; tick the box and the file updates for you.

Time machine for any note

Right-click a tab in a git repo for a slider that walks every commit that touched the file. Scrub through your past selves and one-click restore any version — as an unsaved edit, so you always have an undo path.

Power tools

Workflow that bends to your habits — and the keyboard shortcuts to drive it.

Ctrl+Shift+P

Command palette

Start typing and every action in Marknote is one keystroke away.

Git from the sidebar

Track changes to your notes without leaving the editor. Stage, commit, push, switch branches, and see what changed since your last commit — all from the sidebar.

Export anywhere

Export to HTML, PDF, or print directly. Install Pandoc and you also get Word, EPUB, and LaTeX from the same menu.

Ctrl+S

Save, share, or copy

Save, Save As, Save a Copy, and Share buttons sit one click away in the sidebar. Send the current note through any installed Share target, or write a snapshot beside the original.

Vim modal editing

Optional, off by default. Normal, insert, and visual modes with :w, :q, :wq, and /search — bring your muscle memory.

Custom keybindings

Every shortcut is rebindable. Make Marknote feel like the editor you already trained your hands on.

Workspace config

Each folder you open remembers its own theme, view mode, and pinned files — no fiddling with global settings to switch between projects.

Made for Windows

The polish that only a native app can deliver.

Built into Windows

Double-click any .md file to open it in Marknote. Right-click the taskbar icon for recent notes or to start a new one. Pin the "Recent notes" widget to the Widgets board for one-click access.

Speaks your language

Marknote's interface is available in English, Deutsch, Français, and Español. Pick one in Settings, or leave it on "System default" to follow Windows.

Coding fonts included

JetBrains Mono, Fira Code, Cascadia Mono, Source Code Pro, and Hack are bundled with Marknote — no separate font install needed.

Send feedback in two clicks

About → Report a bug pre-fills a GitHub issue with your version, your operating system, and any recent error. You read and edit everything in the browser before posting.

Wiki links + backlinks

Notes that point back to each other.

Link one note to another by typing [[Note name]]. A live panel shows everything that points back at the note you're reading, and an interactive graph maps the whole web of connections at a glance.

Hover a node to highlight its neighbours.

Live preview

Math, Mermaid, and code — rendered as you type.

The rich preview includes math, diagrams, and syntax-highlighted code — everything bundled inside Marknote. Works fully offline, no internet required.

KaTeX math

\int_{0}^{\infty} e^{-x^2}\,dx \;=\; \frac{\sqrt{\pi}}{2}

How it compares

Why Marknote vs the alternatives.

The dimensions that matter for a markdown editor: where it runs, what it sends home, what it costs, and what works without plugins.

Default behaviour comparison between Marknote, Obsidian, Typora, and VS Code.

Reflects each product's default behaviour as of Marknote v1.8.2. Plugins and extensions can move some rows.

Local-first

Your notes never leave your machine.

No accounts. No telemetry. Your notes only leave your machine when you choose to share them. Settings live in a small file on your own computer, and the rich preview runs entirely offline — math, diagrams, and code rendering all happen on your machine, never the network.

Frequently asked

Questions, answered.

The things people ask before they install — pricing, platform, privacy, lock-in.

Is Marknote really free?

Yes — free for personal and commercial use. No accounts, no pro tier, no upgrade path being teased in the background. The price on the Microsoft Store is £0.

Is Marknote available on macOS, Linux, or Android?

Today, Marknote ships as a native Windows app via the Microsoft Store. A macOS version is planned, and Linux and an Android companion are being explored — see the roadmap for the current state. Marknote's file format is plain markdown, so notes you write today travel cleanly to whichever platforms come next.

What languages does Marknote speak?

English, Deutsch, Français, and Español. Pick one in Settings → Language, or leave it on "System default" to follow your Windows preference. Translations beyond English are a starting point — if you spot a clunky string, the in-app feedback form goes straight to the issue tracker.

Where are my notes actually stored?

Wherever you put them. Marknote doesn't move your files — point it at a folder and it reads and writes .md files in that folder. No database, no proprietary format. App settings live in %LocalAppData%\Marknote\settings.json.

Does Marknote phone home, collect telemetry, or use analytics?

No accounts, no analytics SDKs, no automatic telemetry, no automatic crash reporting. Marknote runs entirely offline — the "Rich" preview even ships KaTeX, Mermaid, and highlight.js bundled locally so renders don't touch a CDN. If you choose to use About → Report a bug, the dialog pre-fills a public GitHub issue with the version, OS, .NET runtime, and the tail of your local crash log so we can act on it — but you review and edit everything in your browser before posting. See the privacy policy for the full breakdown.

How do I get my notes out if I stop using Marknote?

There's nothing to "get out". Your notes are plain markdown files in a folder you chose. Marknote doesn't add proprietary metadata. Open them in any editor, sync them with any service, version them with git. You're never locked in.

Does it work offline?

Fully. The only time Marknote talks to the network is when you push or pull a git remote via the git panel, or when the Store checks for updates. Writing, previewing, exporting, and search all work with no connection.

Available on the Microsoft Store

Try Marknote today.

One install, no setup. Open a folder and start writing — your notes stay on your machine. No account, no cloud, no telemetry.
