Ownly — Your AI Inventory & Ownership Assistant

0. What is Ownly?

Ownly is an AI-powered inventory app that helps people track what they own, find items instantly, and make smarter decisions about buying, keeping, or reselling things. By turning everyday belongings into a searchable, intelligent inventory and marketplace, Ownly reduces clutter, saves money, and encourages more sustainable consumption.

1. Inspiration / Problem

People often forget what they already own, which leads to clutter, duplicate purchases, and wasted time and energy spent trying to find and use items.

Common problems include:

  • Items get lost at home, leading to wasted time and duplicate purchases.
  • Decluttering is overwhelming because people lack visibility into what they own.
  • Buying decisions are often made without context, increasing unnecessary spending and waste.
  • Spending too much time on everyday decisions—such as what to wear or what to pack for a weekend trip—drains mental energy that could be better spent elsewhere.
  • Secondhand marketplaces exist, but they are disconnected from people’s actual inventories, creating unnecessary friction that discourages reuse and exchange.

We already have apps for our memories, like photo galleries, and apps for our money, like banking and investing platforms. But there is still no true system for what we physically own. That is where Ownly comes in.

2. What it does / The Solution

Ownly makes ownership visible, searchable, and actionable.

2.1 Effortless Item Tracking & Retrieval

Users can easily capture photos of individual items or entire storage spaces, such as closets, drawers, and shelves. Using the Amazon Nova API, Ownly automatically:

  • Identifies items and their key attributes
  • Understands storage context and locations
  • Organizes everything into a searchable inventory

Users can later search naturally to find where things are stored, without needing to remember every drawer, box, or closet.

2.2 Smarter Buying & Decluttering Decisions

Users can simply share a photo of an item they want to buy, and Ownly analyzes their existing inventory to:

  • Detect whether they already own similar items
  • Recommend whether the item fits their personal style, such as wardrobe compatibility versus one-off outliers
  • Suggest which existing items could be decluttered or resold to free up space
  • Help users make more intentional, context-aware purchase decisions

This transforms buying and decluttering from gut decisions into informed ones.

2.3 Integrated Marketplace (Circular Economy)

Ownly includes a built-in marketplace directly connected to users’ inventories.

Users can:

  • List unused items for sale in one tap
  • Browse, exchange, or purchase items from other users’ inventories
  • Reuse what already exists instead of buying new

This tight inventory-to-market loop promotes reuse by default and extends the lifecycle of goods.

2.4 Daily AI Suggestions (Your Ownership Bestie)

Ownly works as a day-to-day AI companion that simplifies small but frequent decisions.

It can:

  • Recommend what to wear based on today’s events, weather, and existing wardrobe
  • Suggest what to pack for upcoming trips or activities
  • Surface reminders and insights based on what the user already owns

By embedding itself into daily routines, Ownly drives retention while making ownership feel effortless.

3. How we built it

3.1 Tech Stack

3.1.1 User Interface

Users interact with the Ownly web app, designed to make managing personal items at home simple and convenient.

They can:

  • Capture photos, which Amazon Nova processes to automatically categorize and populate item details
  • Search their inventory
  • Post on the marketplace
  • Chat with the app in a fast, installable experience

3.1.2 Core Platform (Backend)

All user actions flow into a Supabase backend, which provides:

  • Authentication and user isolation
  • Secure data storage for inventory and marketplace listings
  • Realtime updates for messaging and notifications
  • Serverless workflows for background processing
  • Subscription payments via Stripe webhooks and checkout

This forms the system of record for everything a user owns.

3.1.3 AI Intelligence Layer

Ownly applies AI where it adds the most value:

  • Amazon Nova for image understanding and item recognition
  • Semantic embeddings for natural search and similarity matching across inventory

Together, these capabilities allow Ownly to remember what users own, compare new purchase candidates, and generate actionable, context-aware recommendations in real time.

3.1.4 Automation & Marketplace

Background services generate reminders, send notifications, and manage subscriptions. A built-in marketplace connects user inventories directly to peer-to-peer exchange, making reuse and resale seamless.

3.2 Challenges we ran into

One of our biggest challenges with Amazon Nova was prompt tuning for consistent metadata extraction from image uploads and integrating those outputs into Ownly’s inventory pipeline. We also used similarity search to compare new items against existing inventory for personalized recommendations and marketplace matching. Because edge functions have runtime limits, we had to carefully balance accuracy and performance.

In addition, adding a marketplace feature stretched the scope of the app. It required us to handle listing creation, item matching, and recommendation logic on top of the existing inventory system.

4. Accomplishments that we’re proud of

We are proud that we built Ownly as an inspiring and innovative product in the following ways:

  • One Integrated Ownership System: Ownly brings owning, using, buying, and selling into a single app. Instead of relying on fragmented tools for storage, shopping, and resale, Ownly connects the full lifecycle of physical items—from purchase to daily use to resale.
  • Actionable Intelligence, Not Just Tracking: Ownly goes beyond static inventory lists. Powered by AI, it provides context-aware recommendations on what to buy, what to keep, what to declutter, and what to reuse, so users can take meaningful action rather than just record data.
  • AI-Powered, Retention-Driven Experience: Built with Amazon Nova, Ownly delivers fast, intelligent insights through a smooth and friendly user experience. By reducing friction and supporting everyday decisions, Ownly is designed to build habits and drive long-term retention rather than one-time usage.
  • Sustainability by Design: Sustainability is built directly into the product experience. Ownly’s reminders to reuse belongings and its integrated marketplace naturally encourage reuse and resale over buying new, supporting a circular economy with minimal user effort.
  • Strong Monetization Potential: Ownly operates on a monthly subscription model with one basic plan and one premium plan. As the product scales, there is also potential to expand monetization through contextual, intent-driven recommendations and advertising.

5. Impact

5.1 For users

  • Save time finding belongings
  • Make smarter purchases
  • Make decluttering less stressful and more data-driven
  • Save mental energy in day-to-day decision-making

5.2 For the environment

  • Increase reuse of existing items and reduce overconsumption and waste
  • Support a circular economy through peer-to-peer exchange

6. Vision

Looking ahead, Ownly aims to become a holistic ownership intelligence system that supports the full lifecycle of buying, owning, using, and decluttering.

  • Deeper Ownership Context: Ownly will integrate with connected services such as Amazon and email to automatically understand recent purchases and accelerate inventory capture. This reduces manual input while making ownership memory more complete and accurate.
  • Smarter, Personalized Intelligence: As users grow with the product, Ownly will adapt to power users and specific interests. For example, fashion-focused users can receive more advanced styling insights and wardrobe-level recommendations based on what they already own.
  • Thoughtful Monetization Expansion: Beyond subscriptions, Ownly will explore context-aware advertising and recommendations, suggesting relevant items only when users are actively looking for something and when it genuinely adds value rather than interrupting the experience.
