Overview

Klu is a platform for teams building LLM apps to design prompts, run evaluations, and monitor production behavior in one workflow. The homepage describes it as a way to collaborate on prompts, evaluate results, and ship reliable AI experiences with shared tooling that keeps teams aligned.

The product is organized around two main surfaces: Studio for collaborative prompt design and Observe for production observability. Klu also supports enterprise deployments with private infrastructure, governance controls, and dedicated support for teams that need tighter operational control.

Features

Shared prompt workspace

Build, iterate, and version prompts in a shared workspace so product, engineering, and research teams can work from the same source of truth.

Prompt evaluation workflows

Use built-in evaluation workflows and shared evaluation sets to compare prompt changes before shipping them.

Production observability

Track performance, cost, and drift in one place, and keep experiments linked to production data for easier diagnosis.

Model comparison and quality tracking

Compare models and review quality changes over time while connecting prompt work to observed production behavior.

Enterprise deployment controls

Use private infrastructure, governance controls, and permissioned workspaces for regulated or enterprise deployments.

Support and success plans

Get support options that range from community help to priority support and a dedicated success team on enterprise plans.

Use Cases

  • Collaborative prompt development

    Teams can draft prompts, iterate on versions, and run shared evaluation sets before a release so changes are reviewed against the same criteria.

  • Production monitoring and diagnosis

    Organizations can compare quality, cost, and drift across models and prompts while keeping the experiment linked to what is running in production.

  • Enterprise AI operations

    Regulated or larger teams can use private cloud deployment, governance controls, and permissioned workspaces to fit internal operating requirements.

  • Structured optimization workflows

    Product and AI teams can use the platform to move from manual prompt review toward repeatable evaluation workflows and shared decision-making.

  • End-to-end evaluation to observability

    Teams evaluating vendors can start with Studio for prompt work and extend into Observe when they need production visibility.
