How does the global hotkey work?

Select any text in any application — browser, IDE, Figma, Slack, Notes — then press Cmd+Shift+I. The app improves it using AI and either copies to clipboard or pastes directly. 2 seconds instead of 30+ switching to a browser.

How does voice input work?

Press Cmd+Shift+U to start recording. Speak your idea naturally, and Whisper transcribes your speech in real-time. The AI then transforms your spoken words into a polished, optimized prompt. No typing required.

What AI models does it support?

Rephrase creates optimized prompts for all major AI platforms: ChatGPT, Claude, Gemini for text and code; Midjourney, DALL-E, Flux, Stable Diffusion for images; Sora, Runway, Veo 3, Kling for video. Each skill is tuned for specific model syntax.

Yes, you can start free with 10 prompt improvements. The free tier includes all built-in skills, history with search, and global instructions. Pro ($9.99/month) adds unlimited prompts, voice input, and custom skill creation.

Skills are specialized prompt transformation rules. Built-in skills include Video Prompt Generator (for Sora, Runway, Veo 3, Kling), Image Prompt Generator (for Midjourney, DALL-E, Flux), Code Prompt Generator, Professional Slack Message, and more. Pro users can create custom skills.

Why not just use ChatGPT or Claude's built-in prompt improver?

Built-in improvers only optimize for their own model — ChatGPT won't help you write better Midjourney or Sora prompts. Rephrase is model-agnostic: it applies the right techniques for each specific AI tool. Plus, it works globally from any app via hotkey — no need to open a browser, copy-paste, and switch windows. That's 2 seconds vs 30+.

How is Rephrase different from other prompt generators?

Most prompt generators are web-based and work with just one model. Rephrase is a native app that works system-wide via global hotkey — select text in any application and get an improved prompt in 2 seconds. It auto-detects your task type (video, image, text, code) and applies techniques specific to each AI model.

Does it work offline?

An internet connection is required for prompt improvement since the AI processing happens in the cloud. However, the app runs locally on your Mac and only sends the text you select for improvement.

Better prompts. One click. In any app.

Improve prompts for any AI tool directly from the app you're working in — no switching, no browser, no losing focus.
