Promptsy serves as a centralized vault for managing AI prompts, allowing users to save, organize, version, and share their prompts efficiently. It addresses the problem of prompts being scattered across various notes and documents by providing a single powerful repository.

The product offers features including saving and organizing prompts with tags, descriptions, and metadata, version history with diffs and rollback capabilities, one-click copy functionality for instant use in AI tools, sharing and discovery of public prompts, and AI-powered optimization tools that can reformat, expand, or tighten prompts. It also includes a prompt tester feature that allows users to run prompts against multiple AI models simultaneously for side-by-side comparison.

Promptsy works through multiple access points: a Chrome extension for capturing prompts from webpages and injecting them into AI chats, a web app for advanced search and management, a native ChatGPT integration for browsing and inserting prompts within conversations, and an MCP server for connecting AI assistants like Claude directly to the vault.

The benefits include saving hours each week through efficient prompt management, improving prompt quality with AI optimization, and enabling collaboration through sharing and team workspaces. Use cases span marketing (e.g., generating email sequences), development (e.g., code review assistance), writing (e.g., blog post outlining), and research (e.g., summarizing academic papers).

Target users include prompt engineers, AI product managers, content strategists, growth teams, and developers working with AI tools. Integrations support Chrome, web apps, ChatGPT, Claude via MCP, and other AI assistants. The platform is trusted by professionals at companies like Vercel, Linear, Notion, Figma, Stripe, and Supabase.
