Prompt Optimizer

Prompt Optimizer is an AI prompt engineering tool, delivered as a Chrome extension, that refines and rewrites AI prompts directly on any webpage for writers, developers, and people who work daily in AI chat interfaces. Instead of switching tabs to polish a prompt, you select text on a page and an in-page floating toolbar shows suggestion pills, or you open a dedicated popup workspace to write and compare prompt versions side by side before applying or copying the result. It connects to Google Gemini, OpenAI, or a local Ollama model, so on-device users can optimize prompts without sending data to a cloud provider. Concrete features include a custom prompt template library with tags and triggers, reusable text snippets that expand via keyboard shortcuts (inserted with a special prefix), and optional passphrase encryption for stored API keys. Settings and libraries stay in local Chrome storage, and prompts are sent only to the AI provider you configure rather than to the developer's servers. Pricing is not published: installation is free via the Chrome Web Store, though you supply your own Gemini or OpenAI API key (or run Ollama locally). Best for individuals who want fast, in-context prompt refinement without leaving the page they are working on.
