Mac

AI-powered UI bug detection — capture your screen, get a structured bug report. 100% on-device, zero cloud. Tespit is an AI-powered macOS app that captures your screen, detects UI layout issues using Apple Vision and on-device language models, and generates structured Markdown bug reports — all running entirely on your Mac. CAPTURE Select a screen region or entire window with native macOS capture tools. Tespit hides itself during capture so you get a clean screenshot every time. DETECT Apple Vision analyses your screenshot to identify text elements, rectangular regions (buttons, cards, panels), and overlapping bounding boxes that may indicate layout bugs. REASON On devices with Apple Intelligence (macOS 26+), an on-device language model analyses the detection results and produces a detailed, context-aware bug report. On older systems, a deterministic template engine generates equally useful reports. REPORT Get a structured Markdown bug report with severity ratings (Critical → Low), specific issue descriptions, reproduction steps, and actionable fix recommendations. One click to copy. BUGFIX PROMPTS Generate developer-oriented fix prompts from any report — paste directly into your AI coding assistant for instant code suggestions. PRIVACY FIRST Everything runs on-device. No screenshots, data, or analytics leave your Mac. Period. Built with SwiftEnsemble — a Swift-native framework for orchestrating on-device ML pipelines.
