Before comparingPick from a catalog, or get a menu put together
Mealime starts from a recipe catalog and helps you pick from it: the site announces more than 200 customization options to filter by diet and foods you skip, then produces a grocery list sorted by category. It's a well-tested service, claimed by more than 4.5 million users, and its basic version is free.
Popotam doesn't pick, it composes: the menu is written on demand from your constraints, either by Popotam's model or by your own ChatGPT, Claude or Gemini account. Two weeks you ask for never give the same result.
The other difference is less technical but often decisive: Mealime is a North American product. Its recipes, ingredients and units follow Anglo-Saxon habits, and the app's language isn't announced as available in French. Popotam speaks French, counts in euros and sorts the list by the aisles of a French supermarket.
