PagePin AI — Web Annotator

Annotate webpage elements, capture screenshots, and export AI-ready feedback reports. Local-first; no account or tracking.

PagePin AI — Visual Feedback, Screenshots & AI-Ready Implementation Plans Turn visual feedback into actionable development tasks. PagePin AI is a local-first Chrome extension that helps developers, designers, QA engineers, and product teams annotate webpage elements, capture visual evidence, and create structured feedback reports. Instead of describing UI issues through scattered messages or screenshots without context, PagePin AI connects your feedback directly to the elements you select. KEY FEATURES 1. Visual Web Annotations Select HTML elements directly from supported webpages. Attach comments, severity levels, and improvement intentions. Capture CSS selectors, XPath, element text, and positioning information. Display numbered annotation markers on webpages. Retarget annotations when page elements change. 2. Screenshot-Aware Feedback Capture screenshots while creating annotations. Attach screenshots to individual feedback items. Keep screenshot references linked to their annotations. Copy images to the clipboard or download them locally. Include screenshot references in Markdown reports. 3. Flexible Annotation Scopes Organize and export feedback using four scopes: Current page Current website origin Domain and subdomains All locally saved annotations Review a single page or consolidate feedback across multiple pages. 4. Structured Markdown Export Copy feedback reports to your clipboard. Download reports as Markdown files. Include element selectors, URLs, timestamps, and screenshots. Optionally include captured console context. Share reports with developers or use them in coding workflows. 5. AI-Powered Implementation Plans Connect your preferred AI provider to transform annotations into structured implementation plans. Supported provider types include: OpenAI Ollama LM Studio NineRouter Custom OpenAI-compatible endpoints Generate plans containing: Executive summaries Implementation commands Prioritized development tasks Acceptance criteria Original annotation references Screenshot manifests AI features require a configured provider. Remote providers may require an API key or incur separate usage costs. 6. Optional Console Capture Capture browser console context when enabled. Console capture is optional and disabled by default. Review captured information before sharing reports. 7. Local-First Data Storage PagePin AI stores annotations and screenshots locally using browser storage. • No PagePin AI account required. • No built-in advertising or analytics tracking. • Local annotation management. • AI requests are initiated by the user. • External AI providers process data according to their own policies.
