About

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.

About

PromptMason is a desktop application for organizing reusable prompts and building them from shared text blocks. Users can create blocks for roles, background, tasks and formats, then update a block once to revise every dynamic prompt that uses it. The app includes prompt search, fill-in variables, AI-assisted rewriting, prompt evaluation, and privacy checks that flag sensitive information. Its optional local AI model can run on the user’s computer without sending prompt text to a cloud AI provider. Built-in MCP connections let Claude Desktop, Cursor and Claude Code search, fill and save prompt-library content. Users can also access prompts through a Chrome extension, share libraries using their own cloud-storage folders or a network drive, and manage Markdown documents and downloadable AI Skills. A free plan includes all features with limits of 25 blocks and 15 prompts; Pro removes those limits.
