One list from the recipes you actually cook.
Fill Pantry is a free web tool from Lambda Labs / MadeByRobot, LLC. It turns recipe links and pasted ingredient lists into a single grocery list grouped by aisle.
It does not require an account. Recipe sites that publish schema.org Recipe data give the cleanest imports. Sites that block automated fetches still work if you paste the ingredients.
