Governed AI Craftsmanship
We build AI-assisted solutions with systematic verification, documented methodology, and evidence you can trace.
Evidence-based AI services for professionals who need results they can verify.
Echo Angel Studio delivers AI-assisted projects with a governance-first approach. Every decision is documented. Every claim traces to a source. Every deliverable follows a systematic verification process.
We work with professionals who need more than promises - they need proof. Our methodology produces outputs you can audit, defend, and build upon.
Every project follows documented checkpoints and decision gates.
Claims are verified. Sources are cited. Uncertainty is labeled.
You can follow the chain from source to conclusion.
Systematic verification at every step.
We start with verified sources. Primary materials take precedence over secondary. Uncertainty is acknowledged, not hidden.
Every significant decision is logged with rationale. You will know not just what we built, but why.
Implementation follows the plan. Checkpoints confirm alignment. Deviations are documented and justified.
Final outputs include audit trails. You can verify any claim back to its source.
The orchestrator governs the process. The app governs the artifact. The only model in the loop is yours.
A verification platform for professionals in regulated or confidentiality-bound fields: citations grounded by construction, an omission defense, a refuse-or-emit export gate, and a session audit trail — with no model inside either tool.
Case studies demonstrating governed AI craftsmanship.
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.
View Case StudyAn 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.
View Case StudyRetrospective evaluation of a real DC small business against published DMPED scoring criteria. 34 sourced citations across 15 independent sources, with every claim linked to its source for two-click verification.
View Case StudyRetrospective evaluation of a real Atlanta nonprofit against HRSA Healthy Start Initiative scoring criteria. 778 verified data points across 17 independent sources, dual-source research architecture, and every finding linked to its source.
View Case StudyRestaurant nutrition data pipeline with PDF parsing, schema validation, and location-aware search across 52 restaurant chains and 625 Austin-area locations.
View Case StudyAI-directed business transformation: research-grounded pricing strategy, domain migration, evidence-based program development, and ongoing enhancement across multiple project phases.
View Case StudyFive home-display calendar devices compared for a household purchase. Twenty-five sources, nineteen citations, every load-bearing claim linked to a verifiable passage — the same methodology we bring to harder problems, on a topic any reader can audit in under an hour.
View Case StudyKindergarten selection with 97.6% verified data, custom jeong framework, and live decision tool. 4 hours, 17 concerns resolved.
View Case Study4-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.
View Case StudyA personal 10-week program where every load-bearing claim is sourced — delivered through a logging app you can try in your browser. Two new tracking features on a reusable single-file engine, twenty cited sources, and a live demo with the database switched off.
View Case StudyEcho 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.
