80% faster release cycles: How GPTZero deploys multiple times a day while maintaining quality

GPTZero is the world’s leading AI-text identification platform — founded to verify writing authenticity and preserve what’s human. Ranked as the #1 most trusted and reliable AI tool in 2025 by G2, GPTZero currently serves over 10 million individual users, 3,500 educational institutions, and hundreds of leading organizations across hiring, publishing, and legal.

Challenge

Shipping fast without breaking core user workflows

As a first mover in AI text identification, GPTZero saw rapid and lasting adoption, led primarily by universities seeking to preserve academic integrity. As its user base quickly expanded across new industries (including HR, publishing, and legal), the development team sought to enrich the platform with deeper functionality, including team orchestration, document management, and subscription-based workflows.

However, as GPTZero’s product evolved, its existing Cypress suite couldn’t keep pace. With a team consisting of only seven engineers at the time, manually creating and maintaining new tests was a considerable resource drain that directly impacted development velocity. This challenge only compounded with every release cycle, as each additional feature introduced a host of deeply interconnected workflows that needed to be validated before reaching production.

The combination of rapid product expansion, mounting testing overhead, and rising regression risk signaled that GPTZero needed a more scalable testing foundation. Rather than throwing headcount at the challenge, Co-founder and CTO Alex Cui sought an AI-powered solution that would automate end-to-end testing for each new feature shipped.

Having previously consulted with Momentic’s Co-founder, Jeff An, Alex was confident that their AI-powered testing platform was up to the task.

Solution

An AI verification layer that evolves alongside GPTZero’s product

With Momentic, GPTZero began automating end-to-end verification at a pace that matched its rapid product development, covering both new and existing workflows as the platform expanded.

Because Momentic translates natural language descriptions into self-healing tests that adapt to UI changes, the engineering team ramped up quickly. Within the first week, engineers were already validating core workflows end to end, protecting user-facing functionality without slowing feature delivery. “Momentic’s test editor UI is incredibly intuitive,” Alex shares. “None of our engineers were confused about how to use it, and unstable tests are reviewed and quarantined to keep our CI workflow stable.”

As GPTZero’s product surface area continued to grow, Momentic became the foundation for verifying every workflow users relied on. From uncovering frontend re-render loops to flag inconsistencies, database provider race conditions, and performance issues tied to third-party libraries, Momentic consistently surfaced problems that would have otherwise demanded significant manual investigation.

The relationship quickly evolved into a true engineering partnership. As GPTZero scaled rapidly from a seven-person team to more than fifteen engineers, Momentic scaled alongside them — supporting higher test volume, broader coverage, and more complex workflows without adding friction. Momentic regularly joined live debugging sessions with GPTZero’s team, shipping fixes and improvements in real time and helping the company maintain speed and reliability as both teams grew together.

“Momentic is the only solution that shows us when a change disrupts a core feature our users depend on. It’s that level of visibility and coverage that enables teams to ship with confidence.”

Results

An 89% reduction in defect escape rate while accelerating development velocity

With Momentic, GPTZero transformed testing from a recurring operational drain into a leverage point for the engineering team. By significantly reducing the time spent validating releases, the team reclaimed hours that could be redirected toward higher-value work — from iterating on new features to engaging directly with customers and shaping the product roadmap based on real-world feedback.

As a result, GPTZero now moves faster across its development workflow while shipping with greater confidence. Engineers spend less time tracking down regressions and more time building, learning from users, and expanding the platform’s capabilities.

Looking ahead, GPTZero plans to continue scaling its product surface area while maintaining the reliability educators and organizations depend on. Momentic’s platform remains a core part of that evolution, supporting the team as workflows grow more complex and release velocity increases.
