Jev AI Tools

Jev AI Tools is an independent playground for TypeSafe AI’s Jev evaluation model, built to help applications make structured decisions from your inputs.

Upload or paste a sample (or your own) customer message, then run interactive experiments that return typed outputs—choices from named options, rubric scores, or yes-or-no probabilities. You can inspect how these structured answers map to what your application should do next, including thresholds and review/no-action behavior.

The labs cover common decision patterns such as startup assumption review, draft tone and clarity scoring, simulating agent next steps, routing tasks, selecting the most relevant context blocks, and comparing a claim against provided evidence (without web searching). No account is required for the free preview, with anonymous trial credits available for live runs.

What kinds of answers does Jev return?

Jev returns a choice from a named set, a score placed on a defined ordered rubric, or a probability for a yes-or-no question. These are structured values meant for direct application use.

Can I try Jev without signing up?

Yes—anonymous visitors can explore the sample results without an account. Live runs use anonymous trial credits and may prompt before multi-credit requests.

Does Jev rewrite my text or draft content?

No. Draft-related experiments return scores (for example, tone and clarity) rather than rewriting your text.

How should I use Jev answers in my application?

Review the returned structured values and their probabilities, then apply your own thresholds and policies in your code. Jev signals what to consider; your logic decides whether to act, review, or do nothing.

What does “probability” mean for Jev’s scoring and boolean answers?

For rubric scores, the result can land between levels because it’s computed as a probability-weighted position. For boolean questions, it’s a probability of truth (not a simple yes/no verdict).

Does the claim-versus-evidence tool search the web?

No. It compares your provided claim and supplied evidence only, without web search.
