Download WizLook

1. 1

   Install it

   Open the disk image and drag WizLook to your Applications folder. It is signed and notarized by Apple, so it opens like any other app.

2. 2

   Open it once

   That is how macOS learns about the previews. The window that opens asks for a licence key — the previews do not need one, so you can quit right there, or buy a key below and paste it in.

3. 3

   Press Space in the Finder

   Select an Excalidraw drawing, a Jupyter notebook, a canvas or a JSON or YAML file, and press Space. If the Finder still shows its old preview, check that WizLook is switched on under System Settings › General › Login Items & Extensions › Quick Look.

4. 4

   Unlock the app — €6 once

   The licence is for the WizLook app itself: files opened in its window follow your edits, CSV and SVG show WizLook's way, and Google Drive placeholders open as the document. One key, one Mac, every 1.x update included — no subscription and no account. The key arrives in your purchase email; paste it into the window WizLook opens with.

   Works offline

   The key is checked at launch, never while you read, and WizLook keeps running for up to two weeks when the licence server cannot be reached.

   Moves with you

   About WizLook frees the key from this Mac in a click, so it moves to the next one.

   The only thing collected

   Activating sends your key and your Mac's name to Dodo Payments, and that is all — there is no analytics anywhere in the app.

From then on WizLook keeps itself up to date, checking once a day. See what the previews show.
