MetaPrompt

EchoStash is a personal AI-driven prompt management platform that lets you save, organize, search, and reuse your best AI prompts across multiple models with an intelligent search engine. It comes with official prompt libraries curated from leading AI providers (Anthropic, OpenAI, Cursor, and more), starter playbooks for users new to prompt engineering, and AI-powered search that understands your intent to surface the most relevant prompts without requiring exact keyword matches. The streamlined onboarding and user interface ensure a frictionless experience, while tagging and categorization features help you maintain structured libraries. A community prompt library is also in development to share and discover tested prompts. Designed to eliminate the need to reconstruct successful prompts and to deliver consistent, high-quality outputs, EchoStash accelerates workflows for anyone working heavily with generative AI.

Test, collaborate, version, and deploy prompts, from a single place, with PromptHub. Put an end to continuous copy and pasting and utilize variables to simplify prompt creation. Say goodbye to spreadsheets, and easily compare outputs side-by-side when tweaking prompts. Bring your datasets and test prompts at scale with batch testing. Make sure your prompts are consistent by testing with different models, variables, and parameters. Stream two conversations and test different models, system messages, or chat templates. Commit prompts, create branches, and collaborate seamlessly. We detect prompt changes, so you can focus on outputs. Review changes as a team, approve new versions, and keep everyone on the same page. Easily monitor requests, costs, and latencies. PromptHub makes it easy to test, version, and collaborate on prompts with your team. Our GitHub-style versioning and collaboration makes it easy to iterate your prompts with your team, and store them in one place.
