About STVI
AI changed how fast software can be built. Verification has to keep up.
STVI is a Software Testing & Verification Intelligence platform, a product of WeSimplifAI.
The problem
Faster is not the same as easier.
AI coding agents are making software implementation dramatically faster. That is a good thing. Teams can attempt the migrations they once postponed, build more features, add more integrations and turn ideas into working software with unusual speed.
But the engineering decisions do not disappear when the code is generated faster. A migration still raises questions about compatibility, customer disruption and which existing behaviour must survive. Someone still has to understand what the software is supposed to do, check what changed, test the result and decide whether the evidence is enough to trust it.
A recent article by Matt Asay makes this point carefully. Faster implementation does not automatically create spare capacity: when teams find they can do more, they usually attempt more, so the saved time becomes another commitment. Having engineering expertise and having the capacity to apply it are different things.
The article cites one qualitative study, at a single company, in which employees took on more and ran more work at once. Its researcher’s summary: “what was once extra effort becomes standard performance.” The article is clear that this is early research and not proof about every workplace, and we keep that qualification.
Its clearest example is a security audit of an open-source project by two maintainers working with several coding agents. The agents helped find useful work; the people supplied the process for finishing it. One wrote tests that showed each problem, the other fixed it, and two humans examined every issue alongside agents using different models. A longer list of findings can mean a better audit, so counting findings alone tells you little.
As AI increases what teams can build, the amount of software that has to be understood and verified can grow with it. That is the problem STVI was created to address.
From generating software to verifying it
STVI brings the intent and the evidence together.
STVI takes the material that describes the intended product (requirements, specifications, design, source code, existing tests and any available evidence) and turns it into a structured verification picture.
It asks:
- What was intended?
- What was built?
- What should be tested?
- What do the existing tests actually cover?
- What evidence exists?
- What remains unverified?
Testing is part of verification. It is not the whole answer. A test can pass without proving the requirement it was linked to. A large test suite can still leave important behaviour uncovered. Code can exist without satisfying the requirement that motivated it.
So STVI works around the verification claim: a specific statement about what the software is expected to do, where that expectation comes from, what evidence would support it, and what the available evidence actually establishes.
- Intent
- Requirement
- Claim
- Test
- Evidence
- Verdict
What STVI does
Verification across the dimensions that apply.
Depending on the software, the inputs and the environment, STVI looks at some or all of these. The scope of each assessment depends on what can actually be established, and the report says which were assessed.
Functional behaviour
Whether the intended behaviours are supported by evidence.
Unit and module checks
Small, self-contained parts, where the code can be run safely.
Integration and API behaviour
Where the software, the evidence and the environment allow.
End-to-end journeys
Where the software, the evidence and the environment allow.
UI and user flows
Where the software, the evidence and the environment allow.
Negative and boundary behaviour
Invalid inputs, limits and failure paths.
Security and access-control checks
Limited to input handling and signature checks. Not a security assessment.
STVI does not turn missing evidence into a positive result. If something cannot be checked, “Could not be checked” stays a useful answer, and the report says what would settle it.
Built for software developed at AI speed
Build with AI. Verify with STVI.
STVI is not a coding agent and does not compete with the tools that write software. You keep building with the tools you already use.
It is not meant to replace engineering teams, QA professionals, security specialists or the test setup you already have. It connects their work and evidence to the behaviour the software was meant to provide.
Evidence before confidence
What can be established, kept apart from what is assumed.
STVI keeps these separate: coverage, test results, evidence, findings, verdicts, severity, confidence and unresolved questions.
- A passing test is evidence. It is not automatically proof.
- A high coverage figure is useful. It is not a correctness percentage.
- A clean security scan is useful. It does not by itself settle whether the software can withstand attack.
The purpose is to make those distinctions visible.
Why we built it
The ability to create software is changing faster than the way we verify it.
We think that creates a new need. Not simply more testing, but better verification: a layer that connects intent to implementation, tests to claims, evidence to conclusions, and open questions to the next action.
STVI is early. It has completed one real-project assessment, on a product from WeSimplifAI itself, which found no defect, could run few checks and showed what STVI cannot yet do. Results are provisional and not independently validated, and every report says so.
Our direction
We are starting with software verification.
Over time we want STVI to bring together broader kinds of evidence across testing, product experience, architecture, security and governance, while staying explicit about what each method can and cannot establish. That is a direction, not something STVI does today.
The goal is not to make software development effortless. It is to make the growing volume of software more understandable, more testable and better grounded in evidence.
You built it. Now verify it.
