by Google Security Team

Magika is Google's tiny deep-learning model that detects a file's true content type from its bytes β€” over 200 types β€” in milliseconds. At roughly 1MB, it powers safer, more accurate file handling than extension-based guesses.

What Are AI Tools and Utilities?

AI Tools and Utilities is the category for focused, high-leverage applications that solve a specific daily friction point for developers and power users. Unlike broad productivity suites, these tools do one thing and do it exceptionally well β€” detect file types, capture and annotate screens, automate keyboard interactions, intelligently manage clipboard history, or silently optimise how your operating system allocates resources. The AI layer in these tools is typically behind the scenes, improving accuracy and automation compared to their pre-AI predecessors.

What These Tools Help With

  • File type identification without relying on unreliable file extensions β€” using content-based AI classification
  • Screen capture with intelligent OCR, annotation, and instant sharing workflows
  • Keyboard automation that triggers complex multi-step macros from a single shortcut
  • Clipboard managers that remember and semantically search everything you've ever copied
  • System performance monitors that intelligently prioritise CPU and memory for active applications
  • Developer environment tools: AI-enhanced terminals, dotfile managers, and local model runners

Notable Tools in This Category

Google Magika is an AI-powered file type detection library β€” it identifies files by their content (not extension) with 99%+ accuracy across 100+ file types, far surpassing the libmagic heuristics it's designed to replace, and it's open-source under Apache 2.0. ShareX is the gold-standard Windows screen capture tool β€” free, open-source, with OCR, annotation, and 40+ upload destinations built in. AutoHotkey enables powerful keyboard macro programming for Windows power users. Raycast (Mac) is the AI-enhanced launcher replacing Spotlight β€” plugins, snippets, and AI command integration in one keyboard shortcut. Ollama lets developers run LLMs locally on any hardware with a simple CLI, serving as the backbone for many local AI utility integrations.
