PromptLedger

PromptLedger is a web app for teams using generative AI in production who are tired of prompts living in Slack threads and random docs. It provides a central registry for prompts, versions, and model settings, plus automated evaluation so you can see what changed and why quality dropped. Users can run A/B tests across models (e.g., GPT vs Claude) on a fixed dataset, score outputs with rubric-based graders, and generate a simple “release note” for prompt updates. It also adds lightweight governance: approval flows, access controls, and audit trails for regulated environments. This is not a magic “make AI perfect” tool—it's a practical system of record that reduces regressions, speeds iteration, and makes AI behavior explainable enough for stakeholders. Pricing can be per-seat plus usage for evaluations.
