Advanced AI-Powered Prompt Engineering Platform

AI PromptSmith is a software-as-a-service platform for prompt engineering and large language model (LLM) testing. It centralizes prompt design, experimentation, evaluation, and governance for the lifecycle of generative AI applications.
Designed for AI engineers, machine learning practitioners, product managers, and developer teams, the platform provides collaborative prompt versioning, A/B testing, and a multi-model playground. Integrations include OpenAI (GPT-4+), Anthropic (Claude), Google (Gemini), Perplexity, DeepSeek, and Llama.
Security and reliability features include SOC 2 compliance, 256-bit SSL, GDPR readiness, and a 99.9% uptime target, supporting enterprise deployment and governance requirements.
Teams start by designing and organizing prompts in a collaborative workspace. Each prompt can be versioned and A/B tested to compare performance under controlled conditions. The Advanced Playground allows users to adjust parameters such as model selection, temperature, and max tokens, while surfacing metrics like token usage, estimated cost, and latency.
Prompts can be evaluated across multiple providers, including OpenAI (GPT-4+), Anthropic (Claude), and Google (Gemini), as well as Perplexity, DeepSeek, and Llama. This multi-model testing enables side-by-side comparisons to balance output quality, response time, and spend.
Operationalization features include a Token Analyzer for cost and usage insights, a Rules Builder to enforce prompt constraints and team standards, and an Auto Doc Generator to produce consistent documentation. Security layers manage inputs and outputs, while compliance features support SOC 2 and GDPR requirements. An n8n workflow generator helps automate downstream processes.
AI PromptSmith supports development and optimization of LLM-powered features across product, engineering, and data teams. Practical applications include:
