Small web tools I've built for hobbies. Everything here runs entirely in your browser.
Build a card list by dragging card images from scryfall.com onto the page. The list is saved in your browser, and you can copy the card names out when you're done.
Paste a cube list, or pull one from CubeCobra, and see for every creature how many of the cube's removal spells can answer it. Card data and removal tags come from Scryfall. Your list and edits are saved in your browser.
Drop in your MyEBirdData.csv export from eBird to see the first sighting of every species on an interactive world map. Scrub a timeline to watch your life list grow, browse species photos from Wikipedia, and export the whole thing as a video. Everything stays local to your browser.
