In their own words
Promptitude
Promptitude is a web and API platform for teams creating, testing, managing, and deploying prompts in applications. Its interactive playground supports prompt development and one-click comparisons across AI providers and models. Content Storage lets users add their own material to personalize prompt results. Prompts can be shared or embedded on websites and applications, with password protection and visitor-generation limits. Listed integrations include Amazon Bedrock, Anthropic, Google AI, Google Sheets, Groq, Hugging Face, Make.com, Microsoft Azure, NLP Cloud, OpenAI, Perplexity, and Qwen. The REST Prompt API provides code snippets for integration into web and mobile applications. The pricing FAQ says stored content is encrypted and inaccessible to OpenAI. Free accounts include 100,000 tokens for testing, subject to monthly usage limits; the Free plan allows two users, five prompts, two assistants, and 100 generations per month. Paid plans start at $39 a month billed yearly. Prompt A/B tests and the Paid Marketplace are marked as coming soon.
ProofHound
ProofHound is a prompt-optimization platform for LLM classification work, available through an API, self-hosted deployment, or the web. It examines error cases, iterates prompts, validates outputs, and provides controlled deployment and rollback. Dataset uploads accept CSV, TSV, JSONL, JSON arrays, and ZIP files, with field mapping in the interface. Optimization can target overall accuracy or category measures such as recall for high-risk categories and precision for error-prone classes. Immutable prompt versions retain variable configurations, output rules, and differences between revisions. Experiment records include datasets, model configurations, sample judgments, and overall and category metrics. Release controls include gray traffic, A/B testing, full rollout, and one-click rollback. Connections include the web UI, webhooks, API tokens, and MCP. Customers supply their own model provider, and ProofHound says model calls are not charged. A free plan is listed at free, while self-hosted open source is also free.
