Markdown gets a reading surface.
Reports, notes, tables, math, and footnotes render in a quiet document pane — with live preview, reading, split, and source modes one shortcut apart.
Superset Files — a Mac app for local folders
Your folder is the set.
Superset is the workspace.
Open any folder on your Mac and start working. Read Markdown and documents on a calm surface, create and edit notes right where they live, and preview HTML and media beside them — no vault, no import, no lock-in.

Generated 2026-07-01. This folder contains the quarterly pipeline review: a written report, an interactive dashboard, and the analysis that produced both.

Q2 pipeline review
Qualified leads grew 34% quarter over quarter, driven almost entirely by the two channels we doubled down on in April.
The full picture is in dashboard.html — the
short version is that the bet worked, and the details below
say by how much.

what it is
A calm place to read and write the files you already have.
Point Superset at any folder on your Mac and it opens as a workspace. Markdown and documents render cleanly and stay editable in place, HTML and media preview beside them, and everything remains an ordinary file on disk — no vault, no import, no new format to adopt.
demo
Open any folder. Do everything in one window.
Read the Markdown, write a new note beside it, preview the HTML, and refresh the work — without moving the folder or juggling three apps. A folder an agent just handed you is one good reason to want this.
A folder is all you need.

write, don't just read
Make a note where it belongs.
Superset isn't only for reading. Create a new Markdown file inside a folder you already keep, and edit it right there on disk — no vault to adopt, no app deciding where your notes should live. It's the note-taking surface that works on the folders you already have.
the loop
Read it. Edit it. Trust it.
Write and edit in place.
Create a new note inside a folder you already keep, or edit the source underneath — with save-conflict detection, split panes, a command palette, quick open, and search across the workspace.
HTML opens with a boundary.
Generated dashboards preview in an isolated sandbox. Scripts stay off until you turn them on for a file — one at a time, when you decide to.
themes
Eight skins, tuned by hand.
Porcelain is the signature surface. Anodized, Anodized Cobalt, and Anodized Umbra carry the dark side — machined metal rather than glass. Every one is a first-class skin that stays easy to read, light or dark, not an automatic inversion.
Try one. This page is built on the product's own theme tokens.
trust
Built to be safe with the files you open.
Every release runs through an automated safety net first: your files open unchanged, previews stay sandboxed, and every theme stays readable. The build you download is the build that passed.
tested
Every build is checked before it ships.
Each release passes an automated safety net first, so your files open unchanged and nothing slips through untested.
private
Nothing to sign up for.
No analytics, no accounts. Crash reporting is opt-in and stays off until you turn it on.
isolated
Previews stay behind a boundary.
Generated pages preview in a sandbox, and scripts stay off until you allow them for a file — so opening something new is safe.
fair comparisons
Different from the tools around it.
Superset Files sits next to the tools you already use and does the one thing none of them do cleanly: open any folder to read and write the files inside it, in place.

questions
Asked early, answered plainly.
Is this Apache Superset?
No. Superset Files is a Mac app for local folders, Markdown, HTML, LaTeX, media, code, and generated artifacts. Apache Superset is an open-source business-intelligence and data-visualization platform. They are unrelated projects.
Does it move my files into a vault?
No. Superset Files opens the folder where it already lives. Nothing is imported, nothing is copied into an app-owned library, and nothing is written into your folder except the files you deliberately edit.
Is there a web version?
No, by design. The entire point is direct access to your local file system — a browser cannot safely read and write arbitrary local folders the way a native app can. Superset Files is a Mac desktop app.
Does it phone home?
No analytics, no accounts, no telemetry by default. The app reaches the network only to check for updates, to validate your license when you buy and activate it, and — if you turn it on — to send opt-in crash reports. The privacy policy spells out the details.
Can I buy it today?
Yes. It's a one-time purchase — $24 founding price, $39 standard — with a 14-day free trial first, so you can try the full app before you pay. The pricing page has the details.
