Scramble is an open-source Chrome extension that acts as a customizable AI-powered writing assistant, offering an alternative to proprietary tools like Grammarly. It targets users who want more control over their writing enhancement process by allowing configuration of LLM providers, models, and custom prompts, directly within their browser.

How It Works

Scramble integrates with various LLM providers (OpenAI, Anthropic, Groq, OpenRouter) via API calls. Users highlight text on any webpage, right-click to access a context menu, select "Scramble," and choose a predefined or custom prompt. The extension then sends the selected text and prompt to the configured LLM for processing and returns the enhanced text. This approach offers flexibility in choosing AI models and tailoring the enhancement process through custom prompts.

Quick Start & Requirements

• Prerequisites: Node.js and npm.
• Configuration: Requires API keys for chosen LLM providers.
• Development: Run npx tailwindcss -i src/libs/tw-input.css -o src/libs/tw-output.css --minify --watch for CSS builds.
