WebMerge is a browser extension for Chrome and Firefox that aggregates and searches across multiple websites simultaneously. It uses AI to extract structured data from web pages and presents results in a unified, sortable feed.
Features
- Parallel Multi-Site Search: Query multiple websites at once in a single search.
- AI-Powered Data Extraction: Uses OpenRouter or Mistral AI to parse raw HTML to cleaned Markdown and then into structured items (titles, prices, images, dates etc.).
- Custom Site Schemas: Define your own field schemas per site to extract exactly the data you need.
- Result Feed: Browse, sort, and filter aggregated results across all sites.
- Homepage Feeds: Pin sites as "homepage" sources and fetch their latest listings with one click.
- Result Cards: Customisable card layouts with drag-and-drop field ordering, per-site or per-group.
- Site Groups: Organise your sites into named groups and search within a specific group.
How It Works
- Configure Sites — Add search sites with URL templates and field schemas.
- Search — Enter a query; the extension fetches all enabled sites in parallel.
- AI Extraction — Each page's HTML is converted to cleaned Markdown and sent to the LLM, which extracts structured JSON matching your schema.
- Results — Items are merged, sorted by publish date, and displayed in a card grid.
