Meistrari Didn't See a Good Solution for Prompt Engineering, So It's Building One

Introduction

Artificial intelligence (AI) continues to revolutionize various industries, and Brazil-based company Meistrari is stepping up to help developers tackle this rapidly evolving technology. The startup offers solutions for businesses building products based on other large language models (LLMs). Rodrigo Bobrow and Henrique Cunha co-founded Meistrari in 2023 after experiencing firsthand the challenges of developing AI orchestration, specifically prompt engineering.

The Founders’ Journey

The founders started with a product called Perfect Profile, which utilized AI to rewrite users’ LinkedIn profiles and optimize them for search. While creating this product, they encountered applications that could develop front-end and back-end functionality in mere days. However, when it came to AI orchestration, the development process took weeks due to the lack of an easy-to-use solution.

Bobrow recalled: "When we connected our LinkedIn to Perfect Profile, it rewrote your profile to be more optimized for search. While doing that, there were applications to help develop the front end and back end in a matter of days. However, when it came to the AI orchestration, it took weeks because they couldn’t find a solution for easy development."

The founders set out to create a comprehensive, automated system for prompt creation and output evaluation. A prompt is an instruction given to another LLM, defining the quality of the output.

Meistrari’s Platform

Meistrari’s platform requires no programming knowledge and provides quality control for all applications that employ language models like ChatGPT, Claude, and Cohere. This includes everything related to:

Prompt management
System testing
Quality result evaluation
System monitoring in production

"We have three main experiences," Bobrow explained. "One is being able to craft a great prompt. The second is the testing suite where we’ll create 100 test cases for each of your brands so you’ll be able to see how well your prompt is performing in real-life situations. The third is an evaluation system which allows you to configure several evaluators to assess something inside your output."

Meistrari’s Evaluation System

Instead of fine-tuning an LLM as a first approach, Bobrow suggested trying prompt architecting instead.

For example, you can give a prompt to write something funny in the style of a certain person. Meistrari will run it through the evaluator and provide an output score showing whether it’s something worth moving forward with.

Proof of Concept: ‘Prompts Royale’

Meistrari launched its proof of concept, called ‘Prompts Royale,’ on GitHub in 2023. This attracted attention from notable market executives, including the founders of Shopify, Cohere, and OtherSideAI.

Shopify co-founder Tobi Lütke specifically sent Meistrari a message requesting a security feature so that Shopify could use it. This led to receiving over 100 GitHub stars within hours.

Funding and Future Plans

Meistrari has received funding from notable investors and is planning to expand its team to tackle the growing demand for AI solutions. The company aims to make AI more accessible to developers, allowing them to focus on creating innovative products without getting bogged down in technical complexities.

Conclusion

Meistrari’s vision of making AI more user-friendly and accessible is poised to revolutionize the way developers create applications using LLMs. With its innovative platform and dedication to solving real-world problems, Meistrari is set to become a major player in the AI landscape.
