Comparison

Sous Chef vs. Recipe Keeper — which kind of recipe app do you need?

Published August 25, 2026 Last checked August 25, 2026

These two apps aren’t really competing for the same job. Recipe Keeper is a cross-platform recipe organizer built for a household: import recipes, plan the week, generate a shopping list, and keep everyone’s phone in sync. Sous Chef is an iPhone app built around one thing — taking a recipe you already have and changing it on request, in plain language, while keeping the original underneath. One is for running a kitchen. The other is for the ten minutes before you cook.

That’s the actual choice, not “which app is better.” Below is what each one verifiably does, where they genuinely differ, and two honest answers for two different readers.

Side by side

Where they actually differ

Getting recipes in

Both apps import from a website link and from a photo. Recipe Keeper’s site claims “hundreds” of supported recipe sites plus OCR for cookbook and magazine scans; Sous Chef does link and photo import too, plus plain pasted text as a fallback when a page won’t parse. Neither claims to import video recipes; if a dish only exists as a spoken narration, you’re transcribing it either way.

Recipe Keeper’s site also lists importing directly from Instagram and TikTok posts, which Sous Chef does not do. If a meaningful share of what you cook comes from social video captions, that’s a real point in Recipe Keeper’s favor.

Keeping recipes

This is where the two apps stop looking like the same category. Recipe Keeper is a library: recipes go in, get tagged, rated, and organized, and stay there, synced across every device you own — a searchable, permanent collection that follows you from a laptop in the kitchen to a phone at the store.

Sous Chef keeps a recipe too, but the emphasis is different. Your import is the canonical version and it’s read-only — nothing you do to it overwrites it. What you interact with day to day is a working copy you can change and always roll back. There’s no meal-planning calendar or tagging system on top, because that’s not the job it’s built for. If you want a comprehensive personal cookbook browsable by cuisine or dietary tag, Recipe Keeper’s library tooling is further along.

Changing a recipe

This is the one capability Recipe Keeper’s own site doesn’t claim, and it’s the reason Sous Chef exists. Recipe Keeper lets you adjust serving size — pick a new number, and it recalculates the ingredient quantities. That’s a multiply-every-number operation.

Sous Chef treats a change as something that can ripple. Ask it to feed six instead of two, and if the steps reference pan size, batch counts, or timing that depends on quantity, those can update too — not just the ingredient list. Same with a substitution: swap an ingredient and the steps that mentioned it by name get rewritten to match, not just the line where it’s listed. Every change comes back as a typed, server-validated patch — nine patch types cover replacing, inserting, or removing an ingredient or a step, updating recipe metadata, and adding or removing a note. A patch that doesn’t validate is rejected outright, not silently dropped into your recipe. Changed lines show up marked Edited, there’s a running edit count, and there’s an undo that steps back through the history. See it worked through in how to substitute an ingredient and how to scale a recipe.

Cooking from it

Recipe Keeper is read-only once you’re in the kitchen — you’re looking at the recipe, maybe with the serving size adjusted going in. Sous Chef has a step-by-step cooking view with notes and timers (using a Live Activity, so a timer stays visible without keeping the app open), and you can keep making changes mid-session — “I’m out of thyme” doesn’t mean starting over.

Who else in the house can see it

Recipe Keeper syncs your library, meal plans, and shopping lists across every device tied to your account — iPhone, iPad, Android phone, Windows PC, Mac — and its site describes sharing recipes and meal plans by email or social networks. That’s real multi-device, multi-person infrastructure.

Sous Chef doesn’t have that. It’s iPhone-only, and sign-in (Google, email, or Apple through Auth0) exists so your private library survives a lost or replaced phone — it’s not a sync feature, and nothing mirrors your library to a partner’s phone or a shared account. If more than one person needs to see the same recipes and shopping list, Sous Chef has nothing for that today.

Try it: change a recipe and see what actually moved

Say you’ve got a stir-fry recipe in Sous Chef that calls for chicken breast, and you want to swap it for tofu. Type: “swap the chicken for tofu.” The ingredient line changes — but so does the step that said “cook the chicken 6-7 minutes until no longer pink,” because that instruction doesn’t apply to tofu. It gets rewritten to something like “pan-fry the tofu 4-5 minutes per side until golden,” and both the ingredient line and the step show up marked Edited. The original chicken version is still there underneath — nothing was overwritten, you can undo back to it, and the edit count on the recipe reflects exactly what changed.

That’s the distinction this whole comparison comes down to: Recipe Keeper stores a recipe and lets you adjust a number on top of it. Sous Chef changes the working recipe itself, including the parts that depend on what changed, shows you exactly what moved, and keeps the original.

Choose Recipe Keeper if…

• You’re the one running meals for a household, and you need a shared shopping list that updates when someone adds a recipe to the weekly plan, with items auto-grouped by aisle.
• Your family uses a mix of devices — say, an iPhone, an Android tablet, and a Windows PC in the kitchen — and you want one library that’s the same on all of them without extra steps.
• You track nutrition information and want to search your own recipe collection by it, which is a feature on Recipe Keeper’s own listing that Sous Chef doesn’t have.
• You want a permanent, browsable personal cookbook — hundreds of recipes, tagged and rated, that you’re organizing for the long haul rather than editing in the moment.

Choose Sous Chef if…

• You’ve got one recipe open and it’s not quite right for tonight — missing an ingredient, wrong serving count, needs to be vegetarian — and you want that fixed in one sentence instead of manually rewriting three steps.
• You want to see exactly what changed, not just trust that it did. Sous Chef marks edited lines and keeps a log; nothing gets silently rewritten.
• You don’t want to lose the original. If a substitution turns out to be a bad idea, the canonical recipe is still there, untouched, and undo gets you back to it.
• You already live in ChatGPT or Claude for planning dinner. Sous Chef’s MCP connector renders a real recipe card in the chat and lets you cook and edit from there, with the same validation and undo as the app. See /mcp/ for how that works.

Common questions

Does Recipe Keeper have an AI editing feature like Sous Chef’s?

Not stated anywhere on Recipe Keeper’s own site or App Store listing as of August 2026. Its recipe-changing feature is serving-size adjustment, which recalculates quantities; there’s no plain-language request that rewrites ingredients and steps together.

Can I sync Sous Chef between two iPhones?

No. Sous Chef doesn’t do cross-device sync. Signing in preserves your private library if you get a new phone, but it doesn’t mirror your recipes to a second device in real time the way Recipe Keeper does.

Is Recipe Keeper free?

It’s free to download with a capped free tier — 20 recipes — and a Recipe Keeper Pro Upgrade listed at $19.99 on iOS, per its App Store listing, as of August 2026. Check the current price before buying, since app pricing changes.

Does Sous Chef have a shopping list or meal planner?

No, neither is shipped. If a shopping list and weekly meal plan are what you actually need, Recipe Keeper has both, or see the best Paprika alternatives for iPhone for other apps built around planning.

Which app is better for someone who only cooks solo, from their phone?

If nobody else needs to see your recipes and you’re not planning a week of meals in advance, the household-sync features that make Recipe Keeper worth its price stop mattering as much, and the moment-to-moment usefulness of editing a recipe in place is more likely to be what you reach for.

Do I need an account for either app?

Sous Chef doesn’t require one — importing, editing, and cooking all work as a guest, and signing in is optional. Recipe Keeper’s account and sync model isn’t detailed on its marketing site beyond describing cross-device sync as a core feature; check the app itself for its current account requirements.
