Promptsy serves as a centralized vault for managing AI prompts, allowing users to stop losing their best prompts to scattered notes and forgotten docs. It enables saving, versioning, and sharing prompts in one powerful system.

The key features include saving and organizing prompts with tags, descriptions, and metadata, along with blazing-fast search. Version history tracks every change with diffs and rollback capabilities. One-click copy allows instant copying to any AI tool, and sharing features let users share prompts publicly for others to discover. AI-powered optimization helps reformat, expand, or tighten prompts, and a prompt tester runs prompts against multiple AI models simultaneously for side-by-side comparison.

The product works through integrations like a Chrome Extension for capturing prompts from webpages and injecting them into AI chats, a web app for advanced search and team workspaces, a ChatGPT integration for browsing prompts within conversations, and an MCP Server for connecting AI assistants directly to the vault. The approach focuses on accessibility across platforms and AI tools.

Benefits include saving hours every week through efficient prompt management, improving prompt quality with AI optimization, and facilitating collaboration through sharing and team workspaces. Use cases involve generating marketing emails, code reviews, blog post outlines, social media captions, and research paper summarization.

Target users include prompt engineers, AI product managers, content strategists, growth teams, and developers at companies like Vercel, Linear, Notion, Figma, Stripe, and Supabase. Integrations support Chrome, web apps, ChatGPT, Claude, and other AI assistants via MCP protocol.
