The file system wiki · macOS, Windows & Linux

A wiki that is just a folder.

Fiki turns any directory of Markdown into a wiki you can browse, edit, and map. No database. No account. No lock-in. Your notes stay plain files, so every tool you already own keeps working on them.

The Fiki window on macOS: a tree of pages on the left, a rendered page with a diagram in the middle, Read, Edit, and Edit & Read buttons at the top, and the page's attachments listed below.

Why a folder

Most note apps own your notes. Fiki is built the other way round.

The usual deal

  • Notes live in a database only the app can read.
  • Search, history, and backup are whatever the app ships.
  • Sharing means another account on their service.
  • Export is an afterthought, and it loses things.
  • Stop paying and your notes get awkward to reach.

The Fiki deal

  • A wiki is a directory. A page is a folder with an index.md and its attachments.
  • Search with grep. Keep history with git. Back it up with whatever you already use.
  • Share a wiki the way you share any folder: a repo, a synced drive, a USB stick.
  • There is nothing to export. The files are the wiki.
  • Pay once. It is yours, source code included.
  1. 01

    Nothing to learn

    Files and folders. Make a folder, drop an index.md in it, and you have a page. Nest folders to organize. Move a folder to move a page.

  2. 02

    Every tool still works

    Write in Fiki, or in Vim, Obsidian, VS Code, anything. Fiki watches the disk and redraws the page and the tree the moment something changes.

  3. 03

    As many wikis as you like

    One for work, one for the house, one per project. A wiki is a folder, so a new one costs nothing and the last one you had open comes back on launch.

What it does

Everything you want from a wiki. Nothing between you and your files.

The map

See the shape of what you know.

Press ⌘G and the window becomes a map of the wiki. Folders open and close in step with the tree, closed ones show how much is inside, and the page you were reading is lit. It is the same wiki, from above.

Pan with a scroll. Pinch to zoom. Double-click to fit it all back on screen.

Plays well with

Anything that works on a folder of text files works on a Fiki wiki. That is the whole idea.

Questions

Where do my notes live?
In a folder you choose, as plain Markdown files and their attachments. Fiki never copies them anywhere else.
What is the file format?
A wiki is a directory. A page is a folder inside it holding an index.md plus any attachments. The folder's name is the page's name. That is all of it.
Can I keep using my editor?
Yes. Edit the files with anything. Fiki watches the folder and re-renders the page and tree as soon as something changes.
How do I sync between machines, or share with someone?
However you sync folders today: a git repo, Dropbox, iCloud Drive, Syncthing. Fiki does not run a service, so there is no account to make.
Is it a subscription?
No. You pay once, you get the app and its source, and a year of updates. After that, keep using what you have, or buy the next major version if you want it.
What does "source included" mean?
You receive the code the app is built from. Read it, fix it, change it, build it yourself. The only thing you cannot do is resell it.
Which platforms?
macOS on Apple silicon and Intel, Windows on x64 and ARM64, and Linux. One purchase covers all of them.
When can I buy it?
Soon. The app works today and is being readied for release. This page will change the moment it is on sale.

Your wiki should outlive the app you read it in.

With Fiki it does. It is a folder.
