Web Inspector expands Safari on iPhone and iPad with a set of web development tools: Elements: Browse the DOM tree and tap elements on the page to inspect them. View node details, styles, and computed values. Search the DOM, edit an element's HTML, and copy or delete nodes. Console: Type JavaScript commands to debug, modify, and get information about your webpage. Sources: Read the webpage's source with syntax highlighting. Network: See a list of network requests made by the webpage, with headers and responses. Filter requests, or copy one as a cURL command. Resources: Find details about the data stored by a webpage, such as cookies, local storage, and session storage. Tip: If you tap the Web Inspector button and nothing happens, reload the page once..

ēVision is the field intelligence layer of ēfestos.ai, designed to transform how structural steel is identified, assessed, and reused. Using advanced computer vision and AI, ēVision enables engineers, contractors, and asset owners to scan steel elements directly on-site, automatically detect structural components, and extract critical data such as geometry, condition, and connections. Move beyond manual surveys, spreadsheets, and uncertainty. With ēVision, you can: • Identify structural elements instantly Detect beams, columns, connections, and components using AI-powered image recognition. • Measure and quantify in real time Capture dimensions, profiles, and key properties directly from images or scans. • Assess condition and defects Detect corrosion, damage, and surface conditions to inform reuse decisions. • Generate reuse-ready data Convert site observations into structured digital inventories linked to ēfestos.ai. • Bridge field to platform Seamlessly sync data with ēMaps, ēDesign, and ēAnalytics for full lifecycle reuse workflows. Built for the circular construction era ēVision enables a new workflow: scan → understand → reuse Turning existing structures into measurable, valuable, and reusable assets. Why it matters Reusing steel can save up to ~1.5 tonnes of CO₂ per tonne. ēVision makes this scalable by unlocking reliable, data-driven decision-making in the field. Professional-grade performance Designed for engineers and industry professionals, ēVision integrates advanced AI models with practical workflows used in real projects. ēVision is not just a scanning tool. It is the first step toward turning buildings into data, and data into reusable value.
