AI answers you can put to work.
Studios for research, marketing, translation, data and images.
Multi-model workflows for the highest accuracy.
Positions checked by Jev, TypeSafe's decision model.
Example: four models answer a database question side by side.
Studios
Research Studio
Several models answer your question. The synthesis marks which models back or dispute each claim.
See Research StudioMarketing Studio
Several models write to the same brief: hooks, emails, ads, product copy. Keep the draft that fits.
See Marketing StudioTranslation Studio
Several models translate the same text. You see where they differ, and Jev checks the meaning.
See Translation StudioData Studio
Up to 500 prompts across up to 6 models, or Jev answering questions on every CSV row.
See Data StudioImage Studio
The same prompt, multiple image models.
Keimodel sends one prompt to several image models at once. You pick the render that fits.
Open Image StudioSwipe, drag or use the arrow keys to move between them.
Model Pit
A benchmark for your own prompt. Run any prompt and see how long each model took, what its answer cost, and how many claims it backed or disputed.
Published benchmark scores are one click away, each with its source.

Prompt
Is it true that about 70% of online shopping carts are abandoned? Where does the figure come from, and how was it measured?

Priced before you run
Every model carries its credit cost in the picker and its real input and output price per million tokens on the panel, and the total for the lineup you have built sits under the Run button. We meter nothing after the fact.
Or bring your own key
Add an OpenRouter key in Settings and every model response runs on your own account and costs you no credits at all. The synthesis, which reads every answer and lists the claims, and the Jev checks stay on ours.

How to instrument LLM apps with OpenTelemetry
OpenTelemetry (OTel) is the vendor-neutral standard for distributed tracing. The GenAI semantic conventions extend it to LLM calls. This guide covers setting up OTel tracing for LLM applications, exporting to Jaeger or Grafana, and the GenAI conventions.
