Chatting With an AI Coach That Already Knows What You Ate This Week
Quick answer
Most AI chat on your phone starts from zero — ask it what to eat tonight and it has no idea you had pizza on Tuesday, your iron's running low, or you flagged eggs as bothering you last month. Our coach opens the chat with all three already loaded, then answers like it's been paying attention.
ChatGPT is brilliant. It can tell you how many grams of protein are in a chicken breast, what a Mediterranean diet looks like, or draft you a two-week meal plan in ten seconds. What it can't tell you is whether you personally should have the chicken tonight — because it's never seen what you had on Monday, Tuesday or Wednesday.
That's the gap we wanted to close. Not by building a smarter chatbot, but by giving a chatbot access to the only context that actually changes the answer: your own week.
What our coach opens with
When you tap the Coach tab, the conversation starts with four things already loaded:
- Your recent food diary — what you logged yesterday, what you logged today, roughly how much you've had, what you haven't touched.
- Your estimated vitamin and mineral intake versus UK NRV targets. Where you're cruising, where you're falling short.
- Your goals — weight direction, macro targets, diet preferences, exclusions.
- Anything you've flagged in the reactions tracker as bothering you, so it doesn't suggest foods you've already pulled back from.
None of that gets typed into the chat. It's just there, the same way a human coach would remember what you told them last week.
What a real reply looks like
This is an actual conversation from the Coach tab. One prompt, one reply, no edits:
Can you give me some honest advice based on how I've been eating
Honestly, logging your breakfast and lunch today is a massive win because it breaks that cycle of skipping meals you've been struggling with. The main thing I'm seeing is that your protein is still very low at 21g, which is likely why you feel ravenous by the evening. Since you've got about 1,100 calories left, try to aim for a big protein hit at dinner — something like a lean steak or chicken breast — to help you feel properly satisfied. I've also attached the seafood-free meal plan we discussed to help you keep this daytime consistency going; it includes plenty of protein and your favourite pasta dishes.
A few things to notice:
- "Your protein is still very low at 21g" — that's the actual number from the diary, not a guess.
- "About 1,100 calories left" — the coach knows today's remaining budget against the goal.
- "The cycle of skipping meals you've been struggling with" — it's referencing a pattern from previous days, not today.
- "The seafood-free meal plan" — the exclusion was set once, and it's been respected every time since.
- "Your favourite pasta dishes" — picked up from what's been logged and what's been saved to favourites.
Ask a generic chatbot "any honest advice on how I've been eating?" and the best it can do is ask you ten questions first. Ours just answers.
The reply above, as it actually renders in-app.
Asking for a plan
Ask for a meal plan and instead of a wall of text you get a structured card. In this example, the coach saw the seafood exclusion and a weight-loss goal, and produced a three-day plan called Balanced Fuel (No Seafood) with a 1,800 kcal daily target and a one-line description of why it's built the way it is.
The plan card the coach produces. One tap starts it.
The tab most AI meal apps don't have
Here's the bit that doesn't exist anywhere else we've seen: every plan has a Nutrients tab. We score the plan against 27 UK NRVs using McCance & Widdowson food composition data, flag what's low, flag what's missing, and — crucially — tell you how confident we are.
Every plan gets scored against 27 UK NRVs before you start it.
That "Medium confidence" label isn't decoration. It's our own honesty baked into the product — the numbers are estimates from the ingredients in the plan matched to UK food composition data, and the panel says out loud that "actual amounts vary with brands and preparation."
So you get a plan, and before you commit you can see where it'll short you. No other AI meal tool we've used puts that in front of you.
Swap, skip, log
Every day of the plan is broken down by meal with the actual ingredients, weights, calories and macros. Don't fancy the porridge? Swap it. Eating out at lunch? Skip it. Happy with dinner? Log meal puts the whole thing into your diary in one tap — you don't re-type a thing.

The three things we ask it most
After using it for a few months, these are the prompts that keep earning their keep:
- "What's missing from my week?" — it scans what you've logged, cross-references the NRV gaps, and tells you. Not a lecture. A sentence.
- "Something quick for tonight that isn't chicken again." — because it sees the last seven days, it actually can avoid "chicken again".
- "Can you give me some honest advice based on how I've been eating?" — the prompt from the transcript above. The reply varies with the week.
Where it's still rough
Nutrient numbers are estimates. The coach works from ingredient-level UK food composition data — we show a "Medium confidence" badge on the nutrient view for a reason. Actual absorption, cooking losses and your own physiology aren't in the numbers. Treat them as a signal, not a measurement.
No prices, no supermarkets. The coach doesn't know what Tesco charges for a steak or whether Aldi has ribeye in. The shopping list is an ingredient list, not a cost-optimised cart. We're keeping it out of detailed meal-planning claims until we can do it properly.
We're also still tuning recipe detail — sometimes a meal comes with full instructions, sometimes it's a name and an ingredient list. That'll tighten over the next few updates.
And one thing worth saying plainly: we're a food-tracking tool, not a medical device. The coach can tell you what your log looks like and suggest adjustments. It can't diagnose anything. If something feels off beyond food, that's a conversation with a clinician, not a chatbot.
