Chrome extension to visually point at UI elements and copy clean, structured, code-aware context for AI coding assistants.
Key features
- Visual Element Pointing: Hover or click to target an exact UI element on any webpage using an overlay inspector, removing ambiguity about which element is referenced.
- Structured Context Copy: Exports clean, code-aware context (selectors, element attributes, and surrounding DOM snippets) formatted for use with AI coding assistants and prompt inclusion.
- Selector and Metadata Extraction: Gathers useful element metadata such as CSS selectors, IDs, classes, text content, and basic accessibility attributes to help generate accurate code or tests.
- Clipboard & Prompt Integration: Copies the extracted context to the clipboard in developer-friendly formats so it can be pasted directly into AI prompts, editors, or issue trackers.
- Lightweight Chrome Extension: Works in the browser as an extension without needing to modify the target site, enabling fast inspection across sites and apps.
- Context Preservation: Captures surrounding DOM hierarchy and nearby elements to preserve relevant UI context for tasks like layout fixes or component identification.
- Code-Aware Formatting: Produces output tailored to coding workflows (clean snippets and structured descriptions) to improve the quality of AI-generated code and suggestions.
- Visual website inspection directly in Chrome
- Point-to-select exact UI elements on a page
- Copy clean, structured, code-aware context for use with coding assistants
- Generates element selectors and surrounding context suitable for prompts
- Lightweight browser-integrated workflow for prompt preparation
Best for
- Bug Reproduction with AI: Capture exact element context and paste into a prompt so an AI assistant can reproduce and suggest fixes for a UI bug with precise selectors and DOM context.
- Test Generation: Provide an AI model with element selectors and surrounding DOM to automatically generate end-to-end or component tests (e.g., Selenium, Playwright) that target the correct elements.
- Component Refactoring: Extract a component's DOM snippet and metadata to prompt an AI assistant to refactor the component or convert it into a framework-specific component.
- CSS Fixes and Styling Changes: Supply the exact element and its computed context to an AI assistant to propose or generate accurate CSS rules or style adjustments.
- Accessibility Improvements: Copy element attributes and labels to give an AI prompt the necessary context to recommend ARIA roles, labels, or accessibility fixes.
- Documentation and Code Reviews: Quickly capture UI snippets and context to include in PR descriptions, issue reports, or to ask an AI for a review of UI-related code changes.
- Provide precise UI context to AI coding assistants for generating or modifying front-end code
- Extract selectors and markup snippets for writing automated tests
- Debugging and reproduction of UI issues by sharing structured element context
- Accelerate prototyping by copying focused UI fragments into code-generation prompts
- Onboarding or documentation: capture exact UI element context for guides

Turns a smartphone video of an open trench into a centimetre-accurate 3D point cloud, CAD as-built plan and GIS-ready digital twin of buried utilities.
Key features
- Smartphone capture: Field crews record an open trench with a standard iPhone Pro — no specialist scanning hardware and no separate surveying appointment
- Centimetre-accurate point clouds: Reconstruction algorithms developed at ETH Zurich build a high-resolution 3D point cloud of the excavation from the video alone
- Standards-compliant CAD output: Generates as-built plans in DWG and DXF, with couplings and pipe runs identified and measurements simplified
- 3D digital twin and GIS export: Produces a model of the pipe route including building entries that drops into existing GIS systems
- Works without GPS: Captures basement sections and building entry points where GNSS-based surveying fails
- Immediate backfilling: Because capture takes minutes, trenches close right after filming instead of waiting on a survey crew
- Documentation in about 72 hours: Complete records arrive weeks earlier than conventional surveying, enabling prompt connection billing
- Third-party utility capture: Records crossing utilities and as-laid geometry as unbroken 3D evidence, replacing hand sketches
Best for
- A utility network operator documenting residential service connections without booking a surveyor for every site
- A contractor closing a trench the same day instead of leaving it open pending a survey appointment
- Capturing a building entry point in a basement where GPS-based surveying cannot get a fix
- A district heating project producing as-built DWG plans for regulatory sign-off
- Spotting a laying error in the 3D point cloud before backfilling, while the fix is still cheap
- Feeding as-built pipe geometry into a GIS system for long-term network maintenance planning
