Can an AI agent like Muse, Hark, Grok Bot or Instinct plan my meals and workouts?

Muse, Hark Pro, Grok Bot and Instinct are general AI agents. They get errands done across your accounts, and they can write a plan when you ask. Nume is built to run your food and training. It plans them as one day, keeps a record of what you ate and did, and changes the plan from what happened. The two sit side by side: an agent for errands, Nume for how you eat and train.

What Nume does

You answer seven questions, and your first plan arrives in about a minute. Meals sit at your own eating times, one to six a day, in dishes from the cuisines you eat, around the gym, sport or walks you already do. If you want workouts, Nume writes them for the days you can train.

Logging. Tap Had it, type a line such as “two slices of pizza and a coke”, or take a photo of the plate.
Talk. Write “Had pizza for lunch, can my next workout be shorter?” and Nume records the pizza, shortens Wednesday’s session from 45 to 30 minutes, and shows both changes, each with Undo.
Memory you can see. Nume remembers what you tell it, and you can see and delete any of it in Profile.

What general agents do well

Muse

Muse is Meta’s personal AI agent, launched in September 2026 and powered by Meta’s Muse Spark model. Meta says it sends email, books travel, shops for you, remembers what matters to you and makes suggestions unprompted. On food and fitness, Meta’s pages show it turning a saved recipe reel into a grocery list, suggesting a dinner party menu, building fitness plans and adjusting a training plan as the rest of your life shifts. You use it in the Muse app, at muse.ai or in WhatsApp. It started in the US, and Meta has since announced more countries, including Singapore. Meta says it is free for most of what people need, with subscription plans for people who want to do more.

Hark Pro

Hark Pro is the personal assistant from Hark, released in October 2026 on the web, iOS and Android. Hark says it orders food and groceries, sorts email, books flights and appointments, and remembers what you tell it. Its agent, Handoff, works from its own cloud computer with a full browser. Hark suggests tasks from what it knows is on your plate, and builds small apps called Panels, such as exercise trackers. Its pricing page lists Hark Pro as free, pro² at $20 a month for twice the usage, and pro³ at $100 a month for ten times.

Grok Bot

Grok Bot is the agent product from the company behind Grok, launched in August 2026. Its Bots have their own computer, sign in to the tools you already use, learn how you like things done, offer to take on work they notice, and come back when something needs your approval. Its page calls a Bot an AI teammate the whole team works with, and its documentation lists everyday jobs too, such as booking a dinner reservation. You use it in the Grok Bot app on desktop and iOS, and in Slack and Microsoft Teams. Its page lists Premium at $30 a month, Super at $100 and Ultra at $200.

Instinct

Instinct is a personal assistant from Spear Street Technology, Inc., which trades as Instinct. Its site says it “understands what you’re working on and what’s important to you”. You text or call it, and it uses a phone and computer the way you do. Its examples include ordering ingredients for a new recipe, ordering groceries and finding a court for the weekend. Access is by invitation or waitlist, and its terms say users must be 18 or over. Its site lists no price.

What a specialist adds

One plan for the whole day

In Nume, meals and workouts are planned together. A game or a session in the evening shapes the meals around it, with a snack before and dinner after.

A record in numbers, kept across days

Every logged meal is split into its parts, each with an amount, energy and protein, and you can open any item and correct it. Your meals, workouts and weights stay in one place, with your weight trend and how your protein has averaged against the plan. Your daily energy and protein plan is worked out from your details, training and goal, and follows your latest weigh-in. Nume holds the plan and the record together, so each day starts from what actually happened.

Rules every change passes

Every change passes Nume’s own rules before it reaches your plan. It won’t plan very low-calorie days or a target weight below a healthy range for your height, and it never changes a session you or your coach planned.

Changes from what happened

When a meal runs well over or under its plan, the rest of today changes and the meal says why, with a button to keep the first plan. Tomorrow stays as it was. After a full workout the next one steps up. A skipped workout is dropped, and after two misses in a row the next two are made easier.

Using both

Let an agent book the table, order the groceries or answer the email. When you eat out, switch that meal to Out in Nume and name the place or snap the menu, and Nume picks what to order and how much. If an agent has already written you a plan, paste it into Talk or send up to four photos of it, and once you confirm, Nume sets up your week from it.
