Plain-English agent specification
Describe the behavior you want in plain English and generate an agent around that specification rather than tuning prompts or arranging visual blocks.
Relari
RivendicaRelari’s Nuvi turns plain-English specs into testable agents for teams seeking more structure, verification, and control.
Overview
Relari is the company behind Nuvi, an AI agent builder positioned around designing intelligence with intent. The product page describes Nuvi as a tool for turning natural-language specifications into reliable, testable agents.
Across the site, Relari emphasizes a structured approach to AI development: Agent Contracts, Continuous Eval, and plain-English definitions for agent behavior. The message is that teams can move from ideas to agents with more clarity and verification, rather than relying on prompt tweaking alone.
Features
Testable agent output
Create agents that the site describes as reliable and testable, which suggests a workflow centered on validation rather than one-off prompt output.
Agent Contracts
Use Agent Contracts to define and reason about expected agent behavior before deployment.
Continuous evaluation
Apply Continuous Eval to monitor or assess agent behavior over time, based on the site navigation and homepage labels.
No-code builder
Work in a no-code flow aimed at people who want to build agents without dragging blocks or writing prompts from scratch.
Use Cases
Spec-first agent building
Teams that want to describe desired assistant behavior in natural language and turn that description into an agent they can test.
Agent validation and evaluation
Groups that care about reliability and want evaluation to be part of the development workflow, not an afterthought.
Structured AI prototyping
Founders or product teams exploring AI features who want a more structured alternative to prompt-only prototyping.
No-code agent creation
Teams looking for a no-code approach to agent creation without relying on drag-and-drop block assembly.
