Executive Summary

What the company appears to be

MizAI is a self-reported AI-powered civic platform built by one developer (Aggelos Diamantopoulos) in Greece. The platform claims to aggregate public data from official Greek sources like Διαύγεια and ΚΗΜΔΗΣ, and make it accessible through four connected layers: Investigate public records, Participate in review, Use public data for work, and Explore playful civic experiences.

What changed

During OpenAI Build Week, the author extended MizAI with unified search across official sources, evidence-first discovery, AI/manual job finder with alerts, GPT-5.6-powered CV analysis, e-Jesus confessional, Kaseri improvements, English UI, and security hardening. The changes are timestamped in Git history.

Single most important open question

Is there any evidence of actual public usage or adoption beyond the author's own development work?

Note

This is a self-reported, unverified account. No revenue, customer data, traction metrics, or independent validation are available. All claims are from the author’s own description and must be treated as such.

What The Product Actually Is

The description states that MizAI is an AI-powered civic platform with four connected layers:

  1. Investigate public records: Retrieves records from Διαύγεια and ΚΗΜΔΗΣ, preserves identifiers, payloads, linked PDFs, and source provenance; extracts checkable evidence; presents Maths, AI, and Human scores as distinct signals; supports chat with explicit missing-evidence language.
  2. Participate in review: Allows signed-in users to submit moderated ratings that affect score; supports public comments, likes, bookmarks, sharing, correction requests, and contribution leaderboards; keeps different types of scores visibly distinct.
  3. Use public data for work: Provides AI and manual Job Finder paths over Diavgeia; saves job criteria and sends bounded daily alerts; reviews PDF/DOC resumes, marks issues on original pages, and rebuilds ATS-ready CV without inventing claims.
  4. Explore playful civic experiences: Includes Kaseri (a satirical flying game) and e-Jesus (a GPT-5.6 confessional).

The core path is available without an account at mizai.gr.

Claim

MizAI is a working platform with these four layers.

Evidence Author's own description.

Inference The author built it using TypeScript/Next.js frontend and FastAPI backend, integrating with official APIs and document storage systems. AI paths use structured schemas, bounded reasoning/output budgets, idempotency, provider accounting, and store=false for case-content requests.

Positioning & Claim Evolution

The description states that MizAI was built around the idea that “AI should make public data useful to ordinary people without pretending to be the authority.” It emphasizes:

  • Evidence-bound tools: AI scores are separate from human judgment.
  • Explicit boundaries between discovery and confirmed facts.
  • Community participation with moderation.
  • Satirical elements as part of civic engagement.
  • Preservation of source documents and metadata.

During Build Week, the author extended the product with:

  • Unified search across live procurement evidence.
  • Evidence-first unusual-case discovery with explicit uncertainty.
  • AI/manual job finder with alerts.
  • GPT-5.6 routing for bounded planning, structured analysis, chat, CV reconstruction, and e-Jesus.
  • A metered e-Jesus confessional.
  • Competition-ready English UI and translation cache.

Claim

MizAI positions itself as a platform that makes public data useful while maintaining clear boundaries between AI, human, and official sources.

Evidence Author's own description.

Inference The platform aims to democratize access to public information, but also to avoid misrepresenting AI-generated content as authoritative.

Target Customer & ICP

The description does not clearly define a target customer or ideal customer profile (ICP). It mentions:

  • Analysts evaluating procurement cases.
  • Users seeking public-sector job notices.
  • Citizens participating in reviews.
  • General users interested in civic engagement or playful experiences.

It also notes that the core path is available without an account, suggesting broad accessibility.

Claim

MizAI targets analysts, job seekers, and citizens engaged in civic participation.

Evidence Author's own description.

Inference No specific segmentation or persona details are provided beyond general categories. The platform appears designed for a wide audience with varying levels of technical literacy.

Business Model & Pricing Evidence

There is no evidence of any business model or pricing structure in the description. The author states that the core public reviewer path is available without an account, and mentions AI usage being metered for e-Jesus and CV analysis.

Claim

No explicit business model or pricing information.

Evidence Author's own description.

Inference If there is a monetization strategy, it is not described. The platform seems to be focused on utility rather than commercial gain.

Technical & Delivery Signals

The project uses:

  • Frontend: TypeScript/Next.js
  • Backend: FastAPI, SQLAlchemy, Alembic, PostgreSQL
  • Storage: S3-compatible document storage (Minio)
  • AI models: GPT-5.6 Luna, Terra, Sol
  • Tools: Docker, Playwright, Tailwind CSS, React, Pydantic, Tailscale, Temporal

Key technical features include:

  • Structured schemas for AI outputs.
  • Bounded reasoning/output budgets.
  • Idempotency and provider accounting.
  • Private records are excluded from ingestion/scoring/translation.
  • Source-preserving English experience while keeping Greek original authoritative.

Claim

MizAI is technically built with modern stack and follows best practices around AI usage, privacy, and data integrity.

Evidence Author's own description.

Inference The platform appears to be engineered for reliability, traceability, and bounded AI use. However, no production metrics or scalability data are provided.

Traction & Maturity Signals

There is no evidence of traction or user adoption beyond the author’s development efforts. The project is described as a live, public, bilingual multi-product platform, but no customer base, usage statistics, or engagement data are mentioned.

Claim

No traction or maturity indicators.

Evidence Author's own description.

Inference While the platform exists and has been extended during Build Week, there is no indication of real-world usage or impact.

Back to contents

Competitive Context

The description does not mention any competitors. It focuses on how MizAI handles fragmentation in Greek public data and integrates AI with transparency and source preservation.

Claim

No competitive landscape described.

Evidence Author's own description.

Inference The platform may compete with other open data platforms or civic tech tools, but no direct comparison or market positioning is given.

Key Risks & Red Flags

  • Single-person development: The entire project was built by one individual (Aggelos Diamantopoulos), raising questions about scalability and long-term maintenance.
  • No revenue or customer data: No evidence of monetization, users, or adoption beyond the author’s own work.
  • Unverified claims: All statements are self-reported and unverified — no third-party validation or external sources.
  • AI governance concerns: While the platform claims to avoid fraud verdicts and maintain boundaries, it's unclear how these rules are enforced at scale.
  • Limited scope of AI use: The author notes that GPT-5.6 is used in a bounded way, but there’s no evidence of how this is implemented or monitored.

Claim

Risks include lack of team, traction, and scalability; unverified claims; and potential governance issues.

Evidence Author's own description.

Inference The platform may be a prototype or proof-of-concept rather than a scalable product. Long-term viability depends on future development and adoption.

Diligence Questions To Ask The Founders

  1. What is the actual source of public data used? Are there any legal or compliance risks in aggregating it?
  2. How are community contributions moderated, and what happens if someone submits false information?
  3. Has the platform been tested with real users beyond the author’s own use?
  4. What are the plans for expanding beyond Greece or other languages?
  5. How is AI output validated or audited to ensure accuracy and avoid misleading results?
  6. Are there any existing partnerships or collaborations with government bodies or NGOs?
  7. What is the long-term vision for monetization or sustainability?

Claim

These questions aim to probe deeper into technical, legal, and operational aspects.

Evidence Author's own description.

Inference These are necessary due to the lack of external validation and user feedback in the provided information.

Investment/Partnership Verdict

Not evidenced.

Claim

No investment or partnership potential can be assessed without further data.

Evidence Author's own description.

Inference The platform appears to be a personal project with no clear path to commercialization or scale. It may serve as a prototype or proof-of-concept, but lacks indicators of traction, revenue, or strategic value for investors or partners.
