Household assistant
An AI that plans meals for everyone, not just you.
Most meal planners assume you cook for one. PlateHelix is built for households — partners, kids, elders, anyone you cook for. Each person has a profile and the AI keeps all of them in mind, every single time.
- Per-member profiles with goals, allergies, and preferences
- Privacy modes: shared, private to member, or managed dependent
- Compatibility scoring for every recipe across the household
- Safe substitutions and 'cook once, customize plates' instructions
- Chat in natural language — 'What can we cook tonight?'
- Remembers ratings so it stops suggesting what you didn't enjoy
Why a household-aware assistant changes everything
Real kitchens aren't single-user. One adult is cutting saturated fat after a lipid panel. The other is pregnant and tracking folate and iron. A kid won't touch anything green. Grandma's on a blood thinner that interacts with vitamin K. A roommate is vegan on weekdays only.
Generic AI chatbots forget all of that the moment you close the tab. Generic meal planners ask you to pick a single 'diet' and then ignore the four other humans at your table. PlateHelix is the opposite: every person gets a structured profile that survives across sessions, and the assistant runs every suggestion through the whole roster before it ever shows you a recipe.
The result is meals that actually fit your house — not a generic 'family dinner' that someone has to opt out of every night.
How it works
How it works
The assistant sits on top of a structured household model. Here's the loop, every time you ask for a meal.
Resolve who's eating
Pick the people at the table. The assistant pulls each member's preferences, hard rules, dietary style, allergies, dislikes, and any opted-in DNA / lab findings.
Apply the safety hierarchy
Confirmed allergies and clinician diagnoses become hard blocks. User-stated rules layer on top. DNA findings and AI inferences only refine — they never overrule a confirmed safety rule.
Generate options that fit
The assistant proposes recipes scored 0–100 per member, with explicit 'why this fits' notes and any safe substitutions if one person needs a tweak.
Learn from feedback
Save what worked. Skip what didn't. Ratings flow back into the model so the same misses stop appearing — and so cuisines and ingredients you love show up more often.
What it does, in detail
What the assistant does behind the scenes when you type 'quick weeknight dinner for the four of us'.
Memory
Persistent household context
Profiles, rules, ratings, and pantry state all live in your account. The assistant doesn't forget your kid's peanut allergy between sessions.
Privacy
Per-member privacy modes
Adults can mark their own profile private — visible only to themselves. Shared mode is great for partners who plan together. Managed mode lets caregivers maintain profiles for kids or dependents.
Reasoning
Compatibility scoring
Every suggested recipe gets a per-member fit score, plus a household average. You see who it works for, who it's borderline for, and what to swap.
Tone
Conservative by design
The assistant nudges, it doesn't diagnose. It cites where suggestions came from (a stated preference, a lab marker, a DNA finding) and shows confidence so you can trust — and override.
Real households, real plates
Couple, mixed goals
Cutting saturated fat + building muscle on the same plate.
Same protein base, different sauces and sides. The assistant generates one recipe with a 'cook once, customize plates' split.
Family with a peanut allergy
Stir-fry night without sending anyone to the ER.
Peanuts are a hard block on every recipe. Safe sub (sunflower seed butter) is suggested whenever a recipe traditionally calls for them.
Multigenerational household
Vitamin K limits for grandma, iron-rich meals for a teen.
The assistant biases away from large kale-based mains and surfaces lentil + beef + dark-leafy-light dishes that fit both.
Frequently asked
Can different people see different things?
Yes. Each adult member can choose 'shared' or 'private' for their data. Private profiles still inform meal suggestions for the household, but other members don't see the underlying details.
Does it replace a dietitian?
No. PlateHelix is a wellness assistant. It plans meals around the rules and biology you give it, and it cites its sources. For medical decisions, work with a clinician.
What if family members disagree?
The assistant always shows the per-member breakdown and offers per-plate customizations. You stay in charge of trade-offs — it just makes them explicit.
