Hi everyone, we’re Anish and Kasyap aka the team behind Chatter. We met at UPenn and dived deep into LLMs. After working on a couple projects, we realized LLM testing was a growing issue and built Chatter.
🙋♂️ Who is it for?
We built Chatter for developers and companies wanting observability while building with LLMs. If you’re building LLM-powered applications, refining your prompts, and care about their accuracy/performance (incorrect responses, hallucinations, etc), then Chatter is built for you.
⚙️ How does it work?
🏗️ Build / Iterate Fast, with all the features you need
Multiple foundation models, LLM chaining, formatted responses, Jinja2 prompt templating, parameter tuning, and more – all without a single line of code. When you’re done, export the call(s) to your favorite programming language.
🧪 Test on hundreds of inputs, with automatic evaluation
Easily build a test suite as large as you need, and run it all with a single click. Add assertions for each LLM call, with automatic evaluation using anything from regex to LLM-powered methods. Everything is versioned in one place for easy comparison.
🚀 Collaborate
