Every VeggieOS tool, explained in depth

The VeggieOS scanner is a free barcode scanner that checks a product's ingredient list against a database of animal-derived, animal-tested and ambiguous ingredients and returns a vegan verdict in about one second. It names the exact ingredient behind a negative verdict, explains why it is a problem, and suggests vegan alternatives you can buy instead. There is no scan limit and no paid tier.

• Scan a barcode, or photograph the ingredient list if the product has no barcode.
• You get a verdict plus the reasoning: which ingredient, what it comes from, how confident the result is.
• Ambiguous ingredients (E471, natural flavourings, sugar, shellac, glycerin) get an honest "depends on the source" answer rather than a fake certainty.
• Every scan can be saved to your history, pantry or shopping list in one tap.

The VeggieOS AI coach is a free plant-based assistant that answers nutrition, cooking and shopping questions with your own app data in context. It can read your recent scans, pantry, meal plan and goals, and it can take actions such as adding an item to your shopping list or logging a meal. It also produces a weekly insight summarising what changed and what to try next.

• Ask in plain language, in any of the supported languages.
• The coach uses your pantry and scan history, so answers are specific rather than generic.
• It can act: add to pantry, add to shopping list, log a meal, suggest a swap.
• A weekly insight highlights protein, iron, B12 and variety trends from your own logs.

The VeggieOS recipe converter takes any recipe — from a link, a photograph or typed text — and rewrites it as a fully vegan recipe. It replaces each animal ingredient with a specific plant-based substitute at the correct ratio, adjusts liquid, fat, binding and cooking time accordingly, and flags where texture or flavour will differ. It is free and works in fifteen languages.

• Three inputs: recipe URL, photo of a printed page, or plain text.
• Substitutions are quantified: 1 egg = 1 tbsp ground flax + 3 tbsp water for binding, but aquafaba for aeration.
• The converter adjusts method and timing, because plant-based batters and doughs behave differently.
• Converted recipes can be scaled, saved, added to your meal plan and pushed to your shopping list.

The VeggieOS meal planner generates a full week of balanced vegan meals based on your household size, time budget, dislikes and current pantry. Every meal can be swapped, the plan tracks protein and key nutrients across the week, missing ingredients become a shopping list grouped by supermarket aisle, and each version is saved so you can compare or restore earlier plans. It is completely free.

• A week is generated in seconds and stays fully editable.
• The planner starts from your pantry, which reduces both cost and food waste.
• Nutrition is balanced across the week, not forced into every single meal.
• Swap one meal and the shopping list recalculates immediately.

The VeggieOS nutrition tracker logs plant-based meals and tracks the nutrients that matter on a vegan diet: protein, vitamin B12, iron, calcium, omega-3, zinc, iodine, selenium and vitamin D. It shows weekly rather than daily averages, explains absorption factors such as pairing iron with vitamin C, and lets you log meals directly from scans, converted recipes or your meal plan. It is free and has no premium tier.

• Tracks the eight nutrients that actually need attention on a plant-based diet.
• Weekly averages avoid the false alarm of a single below-target day.
• Absorption matters: the tracker explains inhibitors and enhancers rather than showing bare totals.
• Logging is one tap from a scan, a converted recipe or a planned meal.

The VeggieOS impact tracker converts your logged meals, scans and swaps into estimates of animals spared, greenhouse gas emissions avoided, and water and land saved, using published life-cycle assessment averages. Figures update automatically as you use the app, the methodology and sources are shown openly, and milestones can be shared as images. It is free.

• Impact is calculated from your actual logged food, not a generic "average vegan" figure.
• Four dimensions: animals, CO₂e, water and land.
• Methodology and sources are published, and estimates are presented as ranges where the science is uncertain.
• Streaks and milestones give the day-to-day motivation that abstract ethics does not.
