Cardify

Cardify turns Markdown into polished knowledge cards. You write on the left and watch the card render live on the right, with full Markdown syntax, image search and upload, 2,000+ emoji, content highlighting and keyboard shortcuts throughout. Pick from 30+ themes rendered side by side, adjust card size, and use built-in fonts or upload your own. Export a single card or batch-export high-resolution PNG, SVG and PDF files, then download them or share a unique link. It works on phones and tablets too. Creating and previewing is free; paid plans unlock export, with a 7-day trial card and a monthly subscription you can cancel anytime.
