Our verdict on Open Prompt Manager
Open Prompt Manager is a free, open-source Chrome extension for people who keep reusable prompts across multiple AI chat services. It stores a local prompt library in the browser profile, with tools to create, edit, reorder, delete, tag, folder, search, and filter entries. Solo users can insert prompts into supported and configured chat inputs, copy them to the clipboard, or use context-menu actions. The core library works without an account, making it suited to individual browser workflows rather than shared team operations.
Its main strength is coverage across assistants and control over prompt reuse. The listed integrations include ChatGPT, Claude, Google Gemini, NotebookLM, DeepSeek, Microsoft Copilot, GitHub Copilot, Grok, Poe, Kimi, Mistral Le Chat, OpenRouter, Perplexity, Qwen, and Google AI Studio. Variables let users fill in values before insertion, while launchers, keyboard shortcuts, themes, and site permissions allow personal configuration. JSON import and export provide a backup path, and the optional Open Prompt Database lets users browse and copy selected community prompts into their own library.
There is no paid tier: the product is free, and its feature set centers on storage, organization, and insertion rather than prompt generation or refinement. It does not improve prompts, and the product does not describe sharing prompt libraries with teammates. Support is listed through documentation, while the deployment model is limited to a Chrome extension. Choose Open Prompt Manager if you are a solo user who wants one local prompt collection across many AI sites; consider another tool if you need team collaboration, built-in prompt improvement, or a non-Chrome deployment.
