Arcrawls

Overview

Arcrawls is an interactive browser pet that lives directly on your screen and reacts dynamically to website content and sentiment. Powered by local on-device machine learning and browser-based AI, it tracks user browsing habits to unlock custom animations and interactive features. The extension runs entirely offline to protect user privacy without relying on cloud servers. It brings a playful aesthetic and personalized utility to everyday web browsing.

What it does

• Crawls around browser screen edges and reacts to page text, sentiment, and user typing activity.
• Runs 100% offline sentiment analysis using local models like Chrome's Gemini Nano and ONNX Runtime.
• Unlocks over 140 distinct animations, costumes, and interactive toys through active browsing.
• Provides voice-enabled or text chat with custom personas and markdown support.

Who it's for

• Browser Power Users
• AI Enthusiasts
• Developers & Students
• Casual Web Users

Why it works

• Operates completely locally ensuring total data privacy with zero cloud latency.
• Utilizes lightweight WebAssembly and selective DOM truncation to maintain minimal CPU overhead.
• Blends gamification mechanics like XP leveling and cosmetics to boost user engagement.
• Includes practical utility additions like Focus Mode and battery-saving performance controls.

Founder story

Arcrawls was created by developer fujiDevv to bring back the nostalgic joy of 90s desktop companions with modern, private AI capabilities. Built as an open-source project, it addresses the lack of fun, highly interactive browser extensions that respect data privacy.
