Swift · SwiftUINo copy-pasting. No separate AI apps. Just select and go.
Transform selected text in any app — code editors, browsers, notes, email clients. Plyph stays out of the way until you need it.
Use Ollama locally or connect Groq, Gemini, OpenAI, OpenRouter, Cerebras, Cloudflare Workers AI, or Vercel AI Gateway. You choose the provider.
Create reusable prompts with variables like ${selection}, ${language}, ${tone}, and ${style}. Override provider and model per action.
Preview and edit AI output before it replaces your original text. Or enable direct replacement for faster workflows.
Run common actions without touching the mouse. Keyboard-first design for power users who value speed.
Assign different providers, models, and token limits to different actions. Use a fast model for corrections, a powerful one for rewrites.
Plyph has no account system, no analytics, no telemetry, and no background clipboard monitoring. Your text is sent only when you explicitly choose an action.
