Stop debugging AI-invented APIs. Start verifying before you ship.
Verol catches deprecated methods, non-existent functions, and wrong version references in AI coding responses.
AI coding assistants are transformative for development velocity. But they sometimes produce code that references libraries that have changed, APIs that were deprecated, or methods that never existed. The code looks correct until it fails — and by then the debugging cost often exceeds the time saved.
The specific risks of AI inaccuracies for developers
An AI trained on older data may confidently reference a method or endpoint that was deprecated or removed in a recent library version — without any warning.
When a library method logically should exist given the library's naming conventions, AI tools will sometimes invent it — complete with plausible parameters and return types.
Configuration patterns, breaking change behavior, and available features differ by version. AI responses frequently conflate behavior across versions.
Code patterns that were standard practice in older framework versions may be presented as current best practice.
How Verol helps developers
Verol works alongside AI coding assistants in your browser, extracting technical claims — library names, version numbers, method signatures, configuration options — and independently checking them against current official documentation and package registries.
Common questions
Does Verol work with GitHub Copilot?
Verol works on web-based AI chat interfaces including ChatGPT, Claude, and Gemini. For coding queries run through these interfaces, it verifies the technical claims in responses. Native IDE extensions like GitHub Copilot operate outside the browser and are not currently supported.
What kinds of technical claims does Verol verify?
Verol verifies factual claims including library existence, version numbers, API endpoint correctness, configuration option validity, and function signature accuracy — checked against official documentation and package registries.
Is Verol useful for non-developers who use AI to write code?
Yes. Verol is particularly valuable for non-developers using AI to generate code, since they may lack the background knowledge to catch hallucinated technical details.
Verify AI coding suggestions in real time
Verol catches hallucinated APIs and outdated documentation claims before they make it into your codebase.
