Plyph — AI text assistant for Firefox

Correct, rewrite, translate, summarize, and transform text directly in Firefox using your preferred AI provider.

Simply select text on a webpage, choose an action, and let Plyph handle the rest. Review or edit the result before copying it or replacing the original text, without switching tabs or manually copying text into an AI chatbot.

• AI-powered writing — Correct grammar, spelling, and punctuation, improve clarity, or rewrite text in different styles and tones.
• ChatGPT integration — Sign in with your existing ChatGPT account and use your eligible plan without a separate API key.
• Multiple AI providers — Choose from OpenAI, DeepSeek, Gemini, Groq, OpenRouter, Cerebras, Cloudflare Workers AI, B..AI, Vercel AI Gateway, and OpenAI-compatible services.
• Local AI support — Connect to Ollama to run models locally without relying on cloud AI services.
• Custom actions — Create your own reusable AI instructions, with configurable prompts, models, and settings.
• Ask AI — Ask questions about selected text or use your selection directly as a prompt.
• Quick access — Trigger actions through a customizable selection toolbar, right-click menu, browser toolbar, or keyboard shortcuts.
• Preview and replace — Review, edit, copy, or insert AI-generated text before making changes.
• Model selection — Discover available models and choose the one that best suits your needs.

Plyph is designed to keep you in control of your text and AI provider.

Your text is processed only when you explicitly trigger an action. Requests go directly to your configured AI provider or local model server, without passing through a Plyph-operated backend.

Credentials are stored locally, with optional password-based encryption for API keys. Plyph has no analytics, advertising, or tracking.

Cloud providers may have their own usage limits and pricing. Local Ollama models require no cloud API key.

Your text. Your AI. Your choice.
