What Munch can do

Meals

Log, review, edit, confirm, and delete meal records.

“Log two eggs and toast for breakfast.”Create a structured meal.

“Change lunch to two slices of cheddar.”Edit a prior record.

“Show me what you assumed before saving
                                that.”

Review an uncertain draft.

“Delete yesterday’s snack.”Remove a meal record.

Cooking sessions

Keep independent cooking occasions with durable photos, editable timelines, results, and repeat attempts—whether or not a recipe exists.

“I’m starting these spicy wings. I heated the
                                grill to 250°F a couple minutes ago.”

Start a cook with the original message and a photo.

“A couple minutes ago I wrapped them; internal
                                temp was 155°F.”

Append timeline events and preserve relative-time precision.

“When did I last make smoked mac and cheese,
                                and what did I note?”

Search cook history directly, including saved photos and results.

“Cook it again, but use more smoke and save the
                                result as a recipe.”

Create a fresh attempt, compare it, and review a recipe draft without changing earlier history.

Food search and barcodes

Use structured food databases instead of relying only on a generic estimate.

“Find a USDA entry for a medium green
                                apple.”

Search FoodData Central.

“Scan this barcode.”Look up a packaged product.

“Use the 170-calorie label result.”Select a verified match.

“Where did those calories come from?”Review provenance and assumptions.

Saved foods and recipes

Make repeated logging faster while keeping your confirmed version.

“Save this as My Peanut Butter Sandwich
                                Lunch.”

Create a reusable recipe with ingredients and source facts.

“Log my peanut butter sandwich lunch.”Log a saved recipe at the serving amount you confirm.

“What recipes do I have saved?”Search reusable multi-ingredient recipes.

“Forget that saved smoothie.”Remove a saved item.

Daily progress and goals

Use persistent history to answer questions across conversations.

“How much protein do I have left today?”Compare intake with goals.

“Set my daily calorie goal to 2,300.”Update a nutrition target.

“Summarize my macros this week.”Review a date range.

“Which days were highest in fiber?”Analyze longer-term history.

Water and weight

Keep hydration and body-weight history in the same account.

“Log 24 ounces of water.”Add hydration.

“How much water have I logged today?”Review daily hydration.

“Log my weight as 185.4 pounds.”Add a weight measurement.

“Show my weight trend for the last
                                month.”

Review weight history.

Data and account controls

Keep the account portable and revocable.

“Export my meal history.”Create a downloadable export.

“What ChatGPT connections are active?”Review authorized clients.

“Revoke this connection.”Disable a token family.

“Delete my Munch account.”Begin permanent deletion.

Recipes, meal plans, and groceries

Premium accounts can turn recipes discussed with ChatGPT into persistent personal or household data.

“Save this recipe to our recipe book.”Store ingredients, servings, instructions, nutrition, and provenance.

“Plan it for Monday dinner.”Schedule the immutable recipe revision on the shared calendar.

“We have everything except onions.”Add only onions to the shared grocery list; no pantry inventory is inferred.

“What did Mom plan for Monday?”Read the household plan and factual nutrition in another connected account.
