Prompttly

Prompttly is an AI skills and prompt management platform developed by FIHI LABS UG. It helps people create reusable instructions once and keep them available and up to date across multiple AI tools and devices. Users can write skills from scratch, import Markdown files, save useful web content, or capture knowledge from an AI conversation. Prompttly connects with Claude Code and Codex to identify missing or outdated skills and sync them across tools. Its Mac app, web app, and Chrome extension also make a shared library accessible in ChatGPT, Claude, Gemini, and Perplexity, including through in-chat insertion and browser-based saving.

Additional features include AI-assisted prompt optimization, dynamic variables, automatic version history, and support for multi-file skill directories with reference documents, examples, and scripts. MCP-compatible agents can search the library and, with user permission, save skills back. Prompttly offers a free plan, a paid Pro subscription, and a lifetime purchase; team workspaces are listed as coming soon.
