Promptix – send selected text to any LLM from Mac apps with one hotkey

Hacker News

Hey HN, I built this for my own workflow: too much time lost copying text from Notes/Slack/etc. to ChatGPT/Claude and back. Wanted a simple way to query LLMs without leaving the app. Promptix is a small Mac app that triggers on a hotkey for any selected text: - Translate - Fix grammar - Rewrite/improve - Summarize - Text as prompt - Custom prompts (e.g., "Convert bug report to PR description") Key features: - Works in any app: browsers, IDEs, terminals, etc. - Bring your own key: OpenAI, Anthropic, or any OpenAI-compatible (including local like Ollama). No limits or costs from me. - Runs locally on your Mac: full privacy, no data leaves (only selected text). - 5 defaults prompts + unlimited customs. Feedback or ideas welcome. What prompts would you customize?
