One month ago, we launched our Synthetic Data Studio and were blown away by the response and interest level, further validating our core belief: AI developers desperately need better ways to test and evaluate their systems. Today, we're thrilled to announce the next chapter in our journey: Coherence Prompt Studio – the missing piece in the AI development lifecycle that makes testing and iterating on your LLM applications 10x faster.
If you're building AI applications today, this probably sounds familiar: you craft a prompt that works well for a handful of examples, ship it to production, and hope it generalizes to all the messy real-world inputs it will inevitably face. When issues arise, you're left playing whack-a-mole with edge cases while your users experience the consequences.
We call this "building with vibes" – and while it might work in the early days of a project, it quickly becomes unsustainable as your AI applications grow in importance and complexity.
The fundamental problem? Creating comprehensive test cases for LLMs is tedious, time-consuming, and often impossible to do manually at scale. Unlike traditional software where you might write a few dozen unit tests, effective LLM testing requires hundreds of diverse examples covering a wide spectrum of inputs.
Our Synthetic Data Studio was the first step in solving this challenge – helping teams generate high-quality training data. But we recognized that data was just one part of a larger loop. Teams still struggled to integrate testing into their regular workflows.
Prompt Studio completes this picture by automatically generating comprehensive test cases tailored to your specific use case, letting you compare different prompt versions across models, and providing actionable insights to improve performance – all in a seamless, integrated workflow.
Tell us about your use case, and our AI generates a complete, balanced set of test cases – covering edge cases you might not have anticipated. No more manual data entry or painstaking eval creation.
Test different prompt variants and models easily. See exactly where each version excels or falls short, with detailed performance metrics that highlight the differences.
Receive actionable feedback on how to improve your prompts, backed by data from comprehensive testing.
Stop context-switching between spreadsheets, notebooks, and playground environments. Prompt Studio centralizes your entire prompt development process.
"Before Coherence, our prompt development was largely based on intuition and a small set of test cases. Now we can confidently ship new features knowing they've been tested against hundreds of diverse inputs." – Engineering Lead at an AI-first startup
With this launch, we're excited to open up a free tier that lets anyone get started without the manual onboarding process. Sign up today at withcoherence.com and start building better AI applications immediately.
