Show HN: Yoink AI – macOS AI app that writes everywhere (docs, browser, etc.)

https://www.useyoink.ai/

Hey HN! Yoink AI a macOS app that grabs context from any text field (Word, Gmail, Notion, Slack, etc.), rewrites or generates conten in place, and pastes it back. No copy/paste loops or AI rambling. Just select text, hit Cmd+Shift+Y, and it seamlessly edits or replaces directly in your workflow.

The goal is speed and tight control for users frustrated by slow, verbose AI tools. Would love feedback on the UX and output quality.

Try it at useyoink.ai.

Thanks everyone for checking this out! We’re iterating quickly and reading every suggestion, so if you have any ideas or feedback - big or small - please let us know.

Our goal is to make Yoink feel invisible and second nature in your workflow, and your input directly shapes what we prioritize next. If you have a favorite tool or workflow you want to see supported, or features that would make Yoink more useful for you, drop them here. We’re all ears!
