Collecting things of value takes a lifetime.
Now the value of things takes minutes.
With modern technology in hand.
Changes in how we buy and sell have been incredible in recent decades. We designed an app that allows users to photo an object, learn reliable details, including an accurate price range, then links to appropriate market platforms for resale.
For thirty years, buying got easier. Shipping got faster. Storage got cheaper. Amazon removed every friction point between wanting something and owning it. We accumulated.
Now the pendulum is swinging.
Various apps use AI and offer a price for an item.
Question is — what's under the hood?
We approach evaluation as an investigation — providing evidence based on an image, not a verdict. Not quite an appraisal; we scrutinize objects by classification, using 14 specialist protocols each designed for the realities of its category. Three independent AI systems examine every item separately, then synthesize their findings into one consensus valuation backed by real sold data you can verify yourself.
We have a different approach.
TurnOver gives consumers the tools to appraise what they own and move it — into resale markets, donation channels, or organized collections. Community economic growth aligned with ecological goals. Every item diverted from a landfill is value recovered.
11.3 million tons of textiles hit U.S. landfills every year. The circular economy doesn't just make financial sense — it's the only model that scales.
Curious? See what's under the hood:
Harnessing cutting edge Visual Language Models. Flagship models from leaders of industry: Google Gemini, Opus by Anthropic, and GPT-5.4 by OpenAI for unparalleled triple-team scrutiny.
Separate perception for objectivity. Minimizes distortion and error through independent observation. Wider data set with less bias.
Integrates perceptions; a second and third opinion to cross-check and validate results. Review assessment for strongest conclusions.
Informed by professional appraisal methodology, we distinguish 14 object classifications that need specialty expertise and procedure. Each evaluation category receives appropriate custom instructions.
Leveraging market-pricing data and comparative research, every evaluation is anchored by evidence. Source citations included. This process is Multi Model Forensic Analysis™.
Informed by the International Valuation Standards Council (IVSC) — the global standard across 137 countries — and the International Society of Appraisers (ISA) for US and Canadian personal property.
Identify, Examine, Authenticate, Research, Synthesize — the professional appraisal sequence. Engineered into software: Multi-Model Forensic Analysis™. Result quality depends on protocol quality.
The Solution
More than a trend, resale is a systemic shift. The old model of buy new, use, landfill is giving way to something smarter. What you already own has real commodity value. Resale allows possessions to be traded as assets — and TurnOver gives you the tools to do it.
A lot of apps will tell you what something is worth.
A lot of apps will suggest where to sell it.
TurnOver does both — and puts it all in one place.
Valuation
Price range with source citations — not a guess, a researched range anchored to evidence.
Market Proof
Explicit eBay sold comps — real transactions, real prices, links you can verify yourself.
Condition
Detailed item evaluation with condition assessment — what affects the price and why.
Confidence
A confidence attribute on every appraisal — so you know when to trust the number and when to get a second opinion.
Records
Image and text records of every item you appraise — your collection, documented and searchable.
Market Output
38 resale platforms + 5 donation options, ranked by your estimated payout after fees. Sell or donate — with one tap to a ready-made listing.

Secondhand grew five times faster than traditional retail last year. The U.S. resale market is projected to reach $74 billion by 2029.
This isn't a trend — it's a structural shift toward a circular economy. What you already own has real commodity value. The old model of buy new, use, landfill is giving way to something smarter.

Each category follows the same structured approach used by credentialed appraisers (ASA, ISA): establish expertise, examine forensic markers, check authentication, research market data, synthesize a condition-adjusted valuation. A vintage Rolex and a first-edition Hemingway have nothing in common — except that they both deserve an expert who knows exactly what to look for.
Some asset classes require physical inspection, mechanical auditing, or regulatory verification that exceeds digital capabilities. Rather than give you an unreliable number, we redirect you to the right specialist.
We redirect, not reject — per the Professional Ethics Rule.
Other apps guess. We investigate. Three independent AI systems go to work simultaneously — then reach a consensus backed by real sold prices you can verify yourself.
Identifies what you're looking at — the brand, the model, the category — using the same visual recognition technology behind Google Lens.
Scours the live internet for recent sales, auction results, dealer prices, and market trends specific to your item.
Performs an independent forensic examination — checking every visible marking, flaw, and authenticity indicator — then cross-references against verified eBay sold listings and category-specific price guides.
Only after all three investigations complete does TurnOver synthesize their findings into one consensus valuation, backed by real URLs you can verify yourself.
Our proprietary technique is founded upon international standards in appraisal categorization. Every category module mirrors how credentialed appraisers (ASA, ISA) approach valuation: establish expertise, examine the object, verify authenticity, research the market, synthesize a verdict.
Not one AI guess — a three-way neural consensus that delivers institutional-grade item-pricing accuracy. 14 specialist modules, each designed for its category. Real sold data from eBay as ground truth. Confidence scoring that tells you when to get a second opinion. Under two minutes.
"We don't guess. We investigate."
