The Fairies that catch what your AI didn’t.
The coding assistant era is over. Agents now ship code no human reads. You run the agent — Fairy watches the door: pre-verified integrations, a senior engineer who signs off on what ships, and a guarantee behind it.

Verdict
Findings
/exportSoftware that scales. Humans that back the guarantee.
Stripe has human fraud analysts. Nobody calls Stripe a services company. Fairy is built the same way — software does the work, the human signs off and stands behind it. That’s the trust layer the agent era is missing.
Foundation · live now
Pre-verified integrations.
A drop-in library of the integrations agents get wrong — payments, auth, data, ops. Verified once by a senior engineer, safe in every build after. Via MCP or SDK.
$29–99 / mo per kit
Verification · sign-off
An expert signs what ships.
An API call with a human behind it. AI pre-analyzes most of the review; a senior engineer makes the judgment call and signs off. The software does the work — the human backs the guarantee.
$499–999 per call
Maintenance · recurring
An on-call engineer.
Continuous monitoring for the life of your app. Every deploy reviewed, incidents auto-flagged, fixes dispatched when something breaks. The software scales it; the engineer backs it.

The platform
Code first. Then every consequential category.
The agent era starts with code — pre-verified integrations and senior engineer sign-off. Then legal, financial, and every domain where AI gets it wrong at the worst time, each with a credentialed human who backs it.
Code
AI wrote it. A Fairy makes sure it's safe to ship. Security vulnerabilities, logic errors, architecture issues — caught before they hit production.
Risk if unverified: Outages, breaches, technical debt that compounds.
Data Science
AI built the model. A Fairy makes sure it actually works. Pipeline correctness, statistical validity, bias and drift — reviewed by a senior data scientist.
Risk if unverified: Flawed models in production, silent data corruption, biased outputs.
Legal
AI drafted it. A Fairy makes sure it holds up. Contract enforceability, clause risk, regulatory exposure — reviewed by a senior lawyer in your jurisdiction.
Risk if unverified: Unenforceable agreements, hidden liability, regulatory fines.
Finance
AI modeled it. A Fairy makes sure the numbers are right. Reports, models, and projections reviewed by a senior analyst before they go to stakeholders.
Risk if unverified: Misreported figures, flawed assumptions, investor exposure.
Compliance
AI generated it. A Fairy makes sure it files clean. Regulatory submissions and policy documents reviewed by a specialist in your industry.
Risk if unverified: Regulatory penalties, audit failures, license risk.
Security
AI assessed it. A Fairy makes sure nothing slipped through. Threat modeling, auth flows, dependency risk — reviewed by a senior security engineer.
Risk if unverified: Undetected vulnerabilities, compliance failures, breach exposure.
How it works
From AI-generated to production-ready.
Three steps. One Fairy. One sign-off.

A domain expert reviews it
A vetted senior expert — engineer, lawyer, analyst, compliance specialist — is matched to your submission. They catch what AI missed and flag anything that creates real-world risk.
Verified report, at your speed
Instant to 24 hours. Structured findings by severity, a clear verdict, and a signed-off stamp from your Fairy — delivered in any domain.
Expert access, democratized
Top-tier talent normally reserved for the biggest companies — now available to anyone, for a fraction of the price.
Before Fairy, getting a Google staff engineer on your code meant knowing the right person, paying a retainer, and waiting weeks. Most startups never got there. That changed.

With Fairy
Why a Fairy
AI
handles the obvious.
Fairies
handle the rest.
AI is extraordinary at the 80%. Fast, tireless, increasingly accurate. But the last 20% — the nuance, context, and complex scenarios where AI reasoning breaks down — that’s where real risk lives.
A missed authorization check. An unenforceable clause. A compliance gap that only shows up in production. AI doesn’t know what it doesn’t know. A Fairy does.
The old answer was to hire someone full time. A security architect on salary for three code reviews a month. A HIPAA specialist on retainer just in case. Fairy is the new answer — the right Fairy, exactly when you need them, without the headcount.
Fairy exists for the 20% that actually matters.
Ongoing support
One review or a standing relationship.
Use Fairy once for a single high-stakes PR. Or keep your Fairy on retainer as the senior judgment layer your team runs on — available for review, maintenance, and architecture decisions whenever you need them.
Ongoing code review
Every PR your AI writes, reviewed before it ships. Weekly, daily, or on-demand.
Maintenance & refactors
Restructuring a legacy system or migrating a stack? Your Fairy already knows it.
Architecture guidance
Major decisions reviewed before you build — not after you've already built it wrong.
Retainer contracts
Lock in your Fairy monthly. Priority queue, fixed capacity, no rescheduling.
