17 Fit AI coach
AI nutritionist & diet coach
The AI diet coach that knows you
The 17 Fit coach is an AI nutritionist inside your food diary. It sees your meals, weight, steps and fasting, and answers with your own numbers instead of generic advice. It comes with every plan, the free one included, and Pro+ adds the Ultimate coach — an AI team of four experts in one conversation.
Memory
It remembers you from one chat to the next
The coach looks up any day of your diary on its own and remembers your past conversations, so you never have to start from scratch.
- What I remember Your schedule, training days, the family you cook for — the coach takes it into account in every answer. Edit or delete any fact.
- Pinned Pin the answers worth keeping. They stay even when you start the conversation over.
Coach’s character
It talks the way you like
Choose one of six styles and whether the coach speaks as he or she. The choice carries over to all your devices.
- Six styles Friendly, Demanding, Gentle, Brief, Playful or Science. Brief sounds like this: “38 g protein left: cottage cheese, 200 g.”
- The coach writes first At most once a day, and only with a reason: protein running short, a break in logging or the weekend.
Actions
It doesn’t just advise. It acts.
Answers come with ready-made actions: one tap and it’s done.
- Reminders A protein snack at 4 PM? The coach will remind you.
- Menu and shopping Meals for the next few days, shopping list included.
- Log and start Log the suggested food or water, start a fast or a challenge — right from the answer.
A week’s commitment
A goal for the week, checked daily
Agree with the coach on one thing for seven days: protein, calories, water, the number of meals or meal times. The app itself checks it every day against your entries — by rule, not at the AI’s discretion.
- On Today Seven dots: each filled one is a day you kept it.
- Week complete The card shows the result for two more days; decide what’s next with the coach.
Pro+ · Ultimate coach
Four AI experts in one conversation
The Ultimate coach is for those who want the most from AI: a team that digs deep into your data and photos. It gives 10 answers a day, separate from the everyday coach, which is unlimited on Pro+.
- Nutritionist Nutrition science.
- Dietitian Menus, portions and swaps.
- Trainer Movement, strength, recovery.
- Mentor Habits and motivation.
Deep analysis
Not a tip. An action plan.
A hard question, like why your weight loss has slowed, gets a full consultation: your numbers, the real cause, the options and a plan. A simple one gets a short answer.
- Deep or quick Depth follows the question, or switch on Deep to get it every time. If deep analysis is used up for now, the answer comes in quick mode and says so.
- Action plan Steps with numbers, your own foods and a date to check back.
Dossier
A dossier that grows with every conversation
After each conversation, the Ultimate coach updates it on its own: goals, health and restrictions, routine, movement, tastes, what works, what gets in the way and the strategy you agreed on.
- Nothing hidden Every point is in plain view. Change or delete any of them, or clear the whole dossier.
- The next consultation It starts from the dossier, including what you agreed to check.
Photos
Show your plate, get a verdict
Send either coach a photo of your plate, your fridge, a menu or a label. The Ultimate coach first says what it sees, then how it fits your day.
- What I see The dishes and grams appear above the answer, so you can tell at once whether the AI read the plate right.
- Weekly review of your plates On Pro+, once a week when you ask, the coach reviews the week’s numbers and your plate photos and sets one focus for the week ahead.
Is the 17 Fit AI coach free?
Yes, the coach comes with every plan. The free Basic plan includes a small daily allowance of messages, Pro raises it, and on Pro+ the everyday coach is unlimited. The Ultimate coach is Pro+ only, with 10 answers a day.
What is the Ultimate coach in 17 Fit?
The Ultimate coach is the Pro+ version of the AI coach: an AI nutritionist, dietitian, trainer and mentor in one conversation. It answers hard questions with an action plan and keeps a dossier that grows with every conversation. 10 answers a day, separate from the everyday coach.
Can the 17 Fit AI coach replace a doctor or a dietitian?
No. The coach and the Ultimate team — nutritionist, dietitian, trainer and mentor — are AI, not people, and the app reminds you they aren’t doctors. For health matters, talk to a specialist; on Pro+ you can invite your own dietitian or doctor through Personal supervision.
What does the coach remember, and can I delete it?
The facts in “What I remember”, which you approve or add yourself, your past conversations and, with the Ultimate coach, its dossier. You can edit or delete any of it in the app. To erase the copy on 17 Fit’s server, go to Profile → Settings → Data → Privacy & data.
Which AI models does the 17 Fit coach use?
The everyday coach runs on OpenAI or DeepSeek models, and if one fails, the other takes over; the Ultimate coach uses DeepSeek, with OpenAI stepping in only if DeepSeek fails. Requests go through 17 Fit’s server, and the model receives only what the answer needs — your question, a diary summary, the days the coach looks up, its memory and, for Ultimate, the dossier — with no name or contact details.
