OmniKey AI - AI-powered text enhancement, anywhere on your screen

Hey Product Hunt! 👋 I’m excited to share OmniKey AI with you all. OmniKey is a free, open-source app for macOS and Windows that lets you use AI on any text in any app with a simple keyboard shortcut. Select text, hit a hotkey, and OmniKey will: - ✨ Enhance prompts (clarity, structure, tone) before you send them to an AI - 📝 Fix grammar and readability without changing your meaning - 🛠 Run fully custom tasks and an AI agent that can use your terminal and the web A few things I’m particularly excited about: - It works system-wide: email, docs, IDEs, chat apps, browsers—anything that has text. - You can choose your AI provider: OpenAI, Anthropic, or Google Gemini. - On macOS OmniKey can read from your live browser tab, including authenticated pages (internal dashboards, logged-in tools, etc.), so the agent can work with real context without copy-paste. - It’s free and open source, so you can inspect, fork, and contribute. Why I built this: I was constantly copy-pasting between apps and AI tools just to clean up text, improve prompts, or run small coding/writing tasks. It felt like unnecessary friction. OmniKey is my attempt to make “send this to AI and paste the result back” a native, one-keystroke action on your computer. I’d love your feedback on: - What default shortcuts / behaviors feel most natural? - What custom tasks or @-commands you’d want out of the box? - Any rough edges in the onboarding or daily use. If you’re curious, you can: - Download the app: https://omnikeyai.ca/ - Check out the code contribute: https://github.com/GurinderRawal... Thanks for checking it out — I’ll be here all day answering questions, collecting ideas, and shipping improvements based on your feedback. 🙏
