Case studies demonstrating governed AI craftsmanship.

Flagship · Product

The Echo Angel Platform

A verification platform for professionals in regulated or confidentiality-bound fields. The orchestrator governs the process; the app governs the artifact; the only model in the loop is yours. Citations grounded by construction, an omission defense, a refuse-or-emit export gate, and a session audit trail — shipped as a local-first application, with no model inside either tool.

Governed AI · Traceability

Write It Down

A real AI-assisted grocery workflow missed a jar of sesame seeds — and the reason was already on record. We recover the contemporaneous decision note by a read-only query, with the honest failure included: a human approving an unverified assumption at the review step. Named honestly for what it does and doesn't prove — and a zero-PHI sample you can run in one command to recover a record yourself.

AI Governance · Illustrated

The AI Gym — Episode 1

A comic: three AIs, one trainer, and the unglamorous habit that separates the ones who get better from the ones who get hurt. The annotated companion quotes every source verbatim and links it — plus a free four-question governance starter. Check it yourself, or hand it to your AI.

Applied AI · Website Assistant

The Assistant That Would Rather Say “I Don’t Know”

A grounded website assistant that answers only from our own published pages, cites what it drew on, and — the hard part — refuses when the answer isn’t there instead of making something up. Consent-based lead capture is kept separate from the answer content and tied to a privacy policy written to match exactly what it collects. Small and single-purpose by design; the restraint is the point.

Practice · Long-Project Cohesion

The Project That Doesn’t Lose the Plot

An AI assistant starts every session with a blank slate — a months-long project can’t afford to. How we keep long AI-assisted work coherent: a curated project memory that survives sessions, work records whose silent alteration is detectable, and a routine check that no finding quietly falls through. A practice, not a product — described honestly, bounds first, with field results from our own working records.

AI Verification

When AI Gets It Wrong

9 errors in a guide built from 4,392 source items. A gaming build guide that revealed three categories of AI verification failure—and a methodology applicable to legal research, software documentation, and clinical evidence.

AI & the Law

The AI Harm Landscape

An independent research compilation on AI-generated harm and the law — the consumer AI-chatbot litigation wave and the doctrine forming around it. Nine parts, 248 citations across 43 sources, every load-bearing claim click-verifiable to its source, with the evidence base graded on a seven-tier source-trust scale.

Professional Responsibility

When the Brief Cites a Case That Doesn't Exist

A neutral, primary-source survey of Rule 11, the duty of candor, and how courts are calibrating consequences when AI-assisted filings cite cases that don't exist. The 2025–2026 sanctions wave — from admonishment to $15,000 — with every case, rule, and quotation verified against the primary record. Research, not legal advice.

Auditable Home Tech Research

A structured comparison of five home-display calendar devices for a household purchase decision. Twenty-five independent sources, nineteen citation chain entries, every load-bearing claim linked to a verifiable passage. The methodology is the same one we bring to regulatory analysis and legal-support work — applied here to a topic any reader can sanity-check in under an hour.

Personal Training Research Bundle

4-week corrective exercise program with 30 research-grounded exercises across 3 training days, integrated movement quality tracking (Clean / Grind / Miss), and local gym facility analysis. 22 research sources, including peer-reviewed journals, with three-layer citations linking every evidence claim to its source — and, where possible, to the exact passage in the original publication.

A Grounded Training App

A returning athlete's 10-week cut-and-restore program, grounded claim-by-claim in published research and delivered through a logging app — not a static PDF. Built on a reusable single-file engine with two additive tracking features (a cardio logger and a daily-fuel panel); nineteen findings across running, nutrition, lifting, and swimming, backed by twenty cited sources; and a live demo that runs locally with the database connection switched off. The research even overrode the athlete's own favorite running cue.

Confidential Client Work

And More

Echo Angel Studio has produced governed research deliverables for professional services clients under confidentiality. This includes multi-article research suites with verified citations, policy analysis frameworks, benefits research and evidence compilation, and evidence synthesis operations supporting work across legal, regulatory, and policy contexts.

The portfolio items shown here represent our public-facing work. The depth and rigor of our confidential engagements is significantly greater.
