Executive Summary

What the company appears to be

UnAI Evidence — Explainable Portrait Analysis is a self-reported tool that allows users to upload a portrait image and receive a structured, evidence-based report on visible editing-related signals. It uses GPT-5.6 Sol as its reasoning layer to analyze deterministic measurements (e.g., edge density, luminance spread) and image features, producing a report with evidence index, confidence levels, approximate locations of findings, alternative explanations, and limitations.

What changed

The author describes the project as evolving from a Lovable prototype into a structured product during Build Week. It includes an architecture designed around strict JSON schema outputs, separation of evidence from confidence, image-first explanation design, and optional GPT Image 2-based reinterpretation with consent.

Single most important open question — commercial due-diligence read

Is there any evidence that this tool has traction or adoption beyond the author's own development environment? The description does not state whether it is used by others, monetized, or integrated into platforms. It also lacks data on how many users have interacted with it or what kind of feedback it received.

What The Product Actually Is

The description states that UnAI Evidence is a tool for analyzing portrait images and presenting visible editing-related signals in an explainable way. It works by:

  • Accepting user-uploaded portraits with explicit consent;
  • Locally validating the image and creating a cost-limited 1024 px analysis copy;
  • Measuring lightweight deterministic signals such as edge density, luminance spread, saturation, and compression hints;
  • Sending this data to GPT-5.6 Sol for structured report generation;
  • Presenting results visually with thin arrows pointing to evidence locations and expandable explanations;
  • Optionally offering a separately consented GPT Image 2 edit that creates one clearly labeled naturalized interpretation.

The tool is described as deliberately not claiming to recover the true original, nor to prove that an image is fake. It is an explainability aid for visible signals only.

Evidence

  • Author’s own write-up.
  • Technology stack: TypeScript/React, TanStack Start, Tailwind CSS, OpenAI APIs (GPT-5.6 Sol, GPT Image 2), Codex.

Inference

  • The product is a proof-of-concept or prototype built for a hackathon.
  • It uses multimodal AI to analyze images and generate structured reports.

Positioning & Claim Evolution

The author states that the tool asks a more useful question than traditional detection tools: “what visible editing-related signals are present, where are they, and what ordinary camera or processing effects could explain them?”

It positions itself as an alternative to systems that reduce uncertainty to one unexplained percentage, aiming instead for transparency in its findings.

Evidence

  • The tagline: “Where portrait polish ends, explainable evidence begins.”
  • The project's inspiration section explicitly contrasts it with current tools.
  • It emphasizes the importance of separating evidence from confidence and avoiding accusations.

Inference

  • The positioning is rooted in a critique of existing AI detection tools that lack transparency or context.
  • It aims to shift user perception from accusation to explanation.

Back to contents

Target Customer & ICP

The description does not explicitly name target customers or define an ideal customer profile (ICP). However, it implies usage by individuals who upload portraits and seek clarity on editing signals.

Evidence

  • The tool requires explicit user consent for analysis.
  • It is designed for users who want to understand visible edits in a portrait.
  • It is not described as targeting enterprises or platforms.

Inference

  • Likely early adopters or tech-savvy individuals interested in AI-generated content verification.
  • Possibly journalists, researchers, or social media users concerned about authenticity.

Business Model & Pricing Evidence

There is no evidence of pricing, monetization strategy, or business model in the description. The tool appears to be a prototype built for a hackathon and lacks any indication of commercial use.

Evidence

  • No mention of revenue streams, subscriptions, or paid features.
  • The project was submitted to a hackathon (OpenAI 2026).
  • It includes optional services such as Community Forensics but does not describe how they are monetized.

Inference

  • Likely non-commercial at this stage.
  • Future versions may introduce monetization through hosted services or enterprise licensing.

Back to contents

Technical & Delivery Signals

The tool is built using:

  • TypeScript/React with TanStack Start and Tailwind CSS;
  • Server functions via OpenAI Responses API;
  • GPT-5.6 Sol for structured reasoning;
  • GPT Image 2 for optional reinterpretation;
  • Codex as the primary development environment.

It uses deterministic measurements and a strict JSON schema to guide GPT outputs, separating evidence from confidence and ensuring alternative explanations are included.

Evidence

  • Technology tags: codex, gpt-5.6-sol, gpt-image-2, react, tailwind-css, tanstack-start, typescript, vitest.
  • Author’s own write-up details architecture and prompt engineering.

Inference

  • The system is designed with cost-efficiency in mind (e.g., downsizing images, limiting model calls).
  • It is built for reproducibility and testability.

Back to contents

Traction & Maturity Signals

There is no evidence of traction or adoption beyond the author’s own development. No customer data, usage metrics, or user feedback are provided.

Evidence

  • The project was submitted to a hackathon.
  • No mention of users, customers, or real-world deployment.
  • The tool is described as a prototype with future steps including benchmarking and broader accessibility testing.

Inference

  • The product has not yet reached market traction.
  • It may be in early-stage development or prototyping.

Back to contents

Competitive Context

The description does not provide information about competitors or the competitive landscape. It only contrasts UnAI Evidence with existing tools that “reduce uncertainty to one unexplained percentage.”

Evidence

  • No mention of competing products or platforms.
  • The author references a CVPR 2025 open-source synthetic-image detector as part of an optional service.

Inference

  • The tool may compete with AI-generated content detection tools, but no direct comparison is made.
  • It could be positioned in the growing field of explainable AI for image analysis.

Open Questions & Risks

  1. No commercial traction or adoption: The tool appears to be a prototype without any evidence of real-world use.
  2. Unverified claims about accuracy: The author states that it cannot reconstruct edit history or prove an image is fake, but there is no validation of its output quality or reliability.
  3. Limited scalability: The architecture is cost-limited and uses only one GPT-5.6 analysis per report.
  4. Dependency on proprietary APIs: Heavy reliance on OpenAI models (GPT-5.6 Sol, GPT Image 2) may pose risks if those services change or become unavailable.

Evidence

  • No data on user engagement, feedback, or performance metrics.
  • The tool is described as a prototype with future steps like benchmarking and multi-model integration.

Questions the description leaves open

  1. What specific use cases are you targeting beyond the hackathon prototype?
  2. Have you tested the accuracy of GPT-5.6 Sol’s structured outputs in real-world scenarios?
  3. How do you plan to scale or monetize this product if it gains traction?
  4. Are there any known limitations or biases in how the deterministic measurements are interpreted?
  5. What is your roadmap for integrating multiple specialist models and calibrating them?
  6. Have you considered legal or ethical implications of labeling images as “edited” or “synthetic”?

Overall Assessment

Not evidenced: There is no evidence of revenue, customers, or traction to support an investment or partnership decision.

The project appears to be a hackathon prototype with strong technical execution and clear intent around explainability. However, it lacks any commercial signal or user engagement data that would justify further due diligence or investment.

Confidence level Low — based on self-reported evidence only, with no third-party validation or performance metrics.
