Cardify

You already write Markdown; Cardify makes it look designed. Type on the left and the knowledge card renders live on the right, with full Markdown, image search and upload, 2000+ emoji, content highlighting and keyboard shortcuts throughout.

30+ themes sit side by side, so picking one is visual rather than guesswork; card size is adjustable and you can use a built-in font or upload your own.

Finished cards export as PNG, SVG or PDF - individually or in a batch of high-res files - and each one can also be downloaded as an image or given a unique share link. Phones and tablets are fully supported.

Creating and previewing cost nothing; export is unlocked by the paid plans, which come with a 7-day trial card and a monthly subscription you can cancel anytime.
