# SlimAI AI Coach: Your Week, Explained in One Sentence and One Action A calorie tracker tells you what you ate. AI Coach tells you where that is taking you, what caused it, and the single next thing worth doing — read from your own data, not a template. Most tracking apps stop at the ledger. You log the food, the app adds it up, and the interpretation is left to you. AI Coach closes that gap: it reads the week you already logged — meals, calories, macros, water, fasting, steps, workouts, weight, body scans — and turns it into a trajectory, a cause, and one action. Every sentence it produces is rule-based and computed on your device from your own numbers. The same week always produces the same sentence. When there is not enough data to say something true, AI Coach says exactly that instead of inventing a number. ## The Four Questions a Coach Answers — and the Three SlimAI Can A human coach answers four questions: where am I heading, why, what do I do right now, and how do I stay accountable when life gets in the way. The first three are arithmetic over data your tracker already holds. The fourth needs a person. SlimAI does the first three and says so plainly. AI Coach is not a replacement for a coach, a dietitian, or a clinician — it is the part of coaching that is math, done every week, on numbers you generated yourself. - **Where am I heading?:** A smoothed weight trend and, when the data supports it, an estimated arrival at your target — with the number of logged days and weigh-ins it was built from shown next to it. - **Why?:** Attribution: which meal drove your calories, which two weekdays cost you the most, and which specific dishes showed up when the week went over. - **What do I do right now?:** One action, not a list. Every coach sentence ends in a button that opens the right screen with the right thing already selected. - **What SlimAI does not do:** No emotional accountability, no negotiation, no medical advice, no diagnosis, and no open-ended chatbot. Those are jobs for a human, and SlimAI does not pretend otherwise. ## Trajectory: A Trend Line, Not Last Week Minus This Week Weight moves for reasons that have nothing to do with fat — water, salt, sleep, the time of day you stepped on the scale. Subtracting your first weigh-in from your last is the fastest way to get a confident number that is simply wrong. AI Coach smooths your weight logs with an exponential moving average over a 14-day span, then fits a least-squares trend line through the smoothed points, using one reading per calendar day. What you see is the direction underneath the noise. The estimate is only shown when the data can carry it. AI Coach requires at least 4 logged days in the week and at least 3 weight readings in the window before it will show a trajectory at all. Below that it names exactly what is missing — "log two more days this week" — rather than showing a soft number. When the trend is flat, or running away from your target, there is no arrival estimate. There is silence. An app that answers "in 40 years" is not being honest, it is being arithmetic. - **The confidence line is always visible:** Every trajectory carries its basis: at current pace, from N logged days and N weigh-ins. Self-logged calories are known to run under-reported, so the size of the input is part of the claim. - **The scale went up but you did everything right:** This is the single most common quit moment in every tracker. When your short-window weight rises while your logging and adherence were good and the underlying trend is still fine, AI Coach says so directly instead of letting you assume failure. - **An honest data-quality warning:** If your trend is rising while every logged day came in under target, AI Coach flags the logging itself rather than handing you a confident forecast built on numbers that do not add up. - **One negative, always paired with a win:** A coach screen can show at most one thing to watch, and it never appears without something true and good alongside it. Guilt is treated as a bug, not a motivator. ## Attribution: Which Meal, Which Days, Which Dishes Knowing you went over is not useful. Knowing that dinner carried 51% of your calories, that Friday and Saturday accounted for most of the overage, and that the same three dishes appear every time — that is something you can act on. AI Coach makes one pass over the week you logged and answers all three: the meal type that dominated, the two weekdays that cost the most, and the specific items behind them. It needs at least 4 logged days before it will rank anything. The result is labelled, not lectured. "Biggest meal → Dinner · 51% of your calories" reads in a second and is screenshot-friendly, which is how most people actually use a weekly summary. ## Your Weekly Score — a Lever, Never a Grade AI Coach scores your week from 0 to 100 across four components: how close you stayed to your calorie target, how consistently you logged, the quality of your macro split, and your activity. The weighting favours the two things that actually predict progress — adherence and consistency. The score exists to point at a lever, not to hand out a grade. There is no red, no fail state, and no shaming copy. A low score renders as "biggest lever this week" and names the one component that would move it most. If you never set a calorie target, the macro component scores neutral instead of zero — punishing someone for a setting they were never asked about is the exact failure mode the rules exist to prevent. Week-over-week change appears once you have two scored weeks. - **Adherence:** How close your logged days landed to the calorie target you are working toward. - **Logging consistency:** How many days of the week actually have food in them — the single strongest predictor of whether any of the rest means anything. - **Macro quality:** How your protein, carbohydrate, and fat split compared with your targets across the week. - **Activity:** Steps and logged workout minutes, weighted lightest — movement helps, but it does not rescue a week of guessed portions. ## One Lesson a Week, Chosen by What Your Week Showed AI Coach includes 12 short micro-lessons, and shows one a week. Which one you get is decided by the rule that dominated your week, so the teaching always answers something you just saw about yourself rather than arriving as generic advice. A lesson you have seen is not repeated inside 90 days. The content is static, written once and reviewed in all 7 app languages — nothing about it is generated on the fly. ## Every Insight Ends in a Button A rule with no next step is an unfinished rule. Every coach sentence carries an action, and every action lands somewhere useful with the context already applied. "Plan that meal" opens your diet plan already filtered to the meal that went over. A scan prompt opens the camera with the right meal type set. A hydration nudge opens the water tracker. A protein prompt opens the swap that fixes it. You do not arrive on a screen and have to re-find your place. The same rules power a single line on your Home screen, so the advice above the fold and the advice on the Coach tab can never disagree. That Home card can be dismissed for the day — and only for the day, because a card you cannot close becomes noise and a card dismissed forever stops being a coach. ## What Is Free and What Is SlimAI Pro The coach card, your trajectory, macros against target, attribution, the win and watch pair, the weekly score, and the weekly micro-lesson are free. They are the part that earns the habit, so they stay unlocked. SlimAI Pro adds the layers that need more of your history: cross-feature patterns, one-tap food swaps, plateau detection with an adaptive target, single-question AI answers on a logged meal, and navigation back through previous weeks. ## How AI Coach Stays Honest Health is a domain where a confident wrong answer costs more than no answer. The rules behind AI Coach are built with that as the starting assumption. - **Every claim declares a minimum sample:** Below its threshold a rule is absent, not weakened. You never see a comparison built on two days of data. - **Patterns, never causes:** Every observation is phrased as something seen in your data. Correlation is not causation, and the copy never blurs the two. - **Deterministic, not generated:** No language model writes any coach sentence. The same week always produces the same output — which matters, because people screenshot these. - **No medical claims:** AI Coach does not diagnose, prescribe, or dose. If your profile carries a medical condition, numeric deficit advice is suppressed in favour of pointing you at a qualified clinician. ## Frequently Asked Questions ### What is the SlimAI AI Coach? AI Coach is a coaching layer inside SlimAI Calorie Tracker that reads the week you already logged — meals, calories, macros, water, fasting, steps, workouts, weight, and body scans — and answers three questions: where your weight is heading, what drove it, and the one thing worth doing next. Every sentence is rule-based and computed from your own numbers, and each one ends in a button that opens the right screen with the right context already applied. ### Is SlimAI AI Coach a chatbot? No. AI Coach has no conversation thread and does not generate its text with a language model. It runs a fixed set of deterministic rules over your logged data, so the same week always produces the same sentence. SlimAI does have one AI question surface — Ask About Your Meal, a single-question answer about one logged dish — but it is separate from AI Coach and is not a chat. ### How does SlimAI estimate when I will reach my goal weight? SlimAI smooths your weight logs with an exponential moving average over a 14-day span, then fits a trend line through the smoothed points using one reading per calendar day. It never subtracts your first weigh-in from your last, because that measures water weight. The estimate appears only when you have at least 4 logged days in the week and at least 3 weight readings in the window. If the trend is flat or moving away from your target, no arrival estimate is shown at all. ### Why does AI Coach sometimes show no numbers? Because the data does not support a claim yet. Every rule in AI Coach declares its own minimum sample, and below that threshold the rule stays silent rather than showing a weaker version. When that happens, the card names exactly what is missing — for example, more logged days or more weigh-ins this week — so you know what unlocks it. ### What does the weekly score in SlimAI mean? It is a 0–100 summary of your week across four components: calorie adherence, logging consistency, macro quality, and activity, with adherence and consistency weighted most heavily. It is designed as a lever, not a grade — there is no fail state and no red, and a low score is presented as the single component that would move it most. If you have not set a calorie target, the macro component scores neutral rather than zero. ### Is AI Coach free in SlimAI? The core of it is free: the coach card, your weight trajectory, macros against target, attribution, the win and watch pair, the weekly score, and the weekly micro-lesson. SlimAI Pro adds cross-feature patterns, one-tap food swaps, plateau detection with an adaptive calorie target, single-question AI answers on a logged meal, and access to previous weeks. ### Can AI Coach replace a dietitian or personal coach? No, and it does not claim to. AI Coach handles the three coaching jobs that are arithmetic over your own data — trajectory, attribution, and the next action. Emotional accountability, edge-case negotiation, and anything clinical need a qualified human. SlimAI provides tracking and pattern tools, not medical advice, diagnosis, or treatment.
