Cloak AI - Local AI Assistant
100% On-Device AI & Image Gen
Free · Designed for iPad. Not verified for macOS.
Get private, on-device AI for iPhone & iPad. Chat offline, humanize text, engineer prompts, summarize documents, draft emails, analyze photos, and care for plants.
Cloak AI is your private, on-device AI assistant for iPhone and iPad, designed to help you chat, humanize text, engineer prompts, summarize documents, write, and analyze with fast, local intelligence.
With Cloak AI, AI processing runs directly on your device hardware. Once a model is downloaded, you can optimize prompts, draft emails, summarize articles, humanize text, and care for plants without needing an active internet connection.
WHY ON-DEVICE AI MATTERS
Most AI apps transmit your private notes, drafts, and messages to remote servers. Cloak AI executes open-weights AI models directly on your hardware with native Apple Metal GPU acceleration:
- Local Processing: AI inference executes directly on Apple Silicon.
- Offline Independence: Use AI on flights, commutes, or off the grid.
- Private by Design: Prompts, drafts, and photos remain stored locally.
- No Accounts Required: Start chatting, writing, and humanizing immediately without sign-ups.
KEY FEATURES
1. Humanize Writing Suite
Transform synthetic or robotic text into natural, authentic human writing.
- Pattern Analysis: Scans text for patterns common in synthetic writing, like repetitive phrasing and uniform cadence.
- AI-Likelihood Score: Provides a heuristic indicator (0-100) and confidence score to assess text traits (presented responsibly as an estimate, not definitive proof of authorship).
- 6 Curated Styles: Rewrite using Natural, Casual, Professional, Friendly, Academic, or Concise tones.
- Preserve My Voice: Retain your authentic tone and vocabulary while smoothing out mechanical phrasing.
- Side-by-Side Comparison: Inspect original and humanized text side by side before saving or copying.
