AI-powered UI bug detection for macOS — entirely on-device.

Website • Privacy • Support

Tespit captures your screen, detects layout issues using Apple Vision + on-device LLMs, and generates structured Markdown bug reports. No data ever leaves your Mac.

Screen Capture  →  Vision Detection  →  On-Device Reasoning  →  Bug Report

1. Capture — select a region or entire window via ScreenCaptureKit
2. Detect — identify UI elements, text, frames, and overlaps with Apple Vision
3. Reason — analyse layout issues using Apple Intelligence (FoundationModels) on-device
4. Report — generate a structured Markdown bug report with severity ratings

• 🔒 100% on-device — no cloud calls, no telemetry on your screen content
• 🧠 Apple Intelligence — leverages FoundationModels for reasoning (graceful fallback on older systems)
• 📸 Flexible capture — region selection or full window capture
• 📋 One-click export — copy reports or generate bugfix prompts for your AI coding assistant
• ⚡ Built with Swift 6 — strict concurrency, modern async/await throughout
