   Perch Intel:
Business Intelligence Without The Noise

Perch Intel is our first dedicated SaaS tool release: 

A competitive intelligence tool that monitors your competitor's website for changes in products, services, pricing, and content. It delivers clear, timely summaries so you can react decisively and make informed decisions to help scale up your business in its dedicated market sector.

Weekly Email Reports

Get a single, easy‑to‑scan report of the week’s most important updates, on a competitor's web page.
Stay informed without constant notifications.

Actionable Insights

See exactly what’s changed using the dedicated Recent Changes Feed.
Allowing you to decide whether to react, adjust your strategy, or log the update for future reference.

Tagging & Prioritization

Monitor your competitor's web pages for specific data such as Prices, Reviews, Features, or Promotions.
Prioritizing the updates that have the biggest impact on your business.

Customizable Monitoring

Choose how often Perch Intel checks for changes: daily, weekly, or twice a week.
Perfect for balancing update frequency with the level of competition in your market.

Competitor Tracking

Create your competitor's bio and add the exact pages you want to monitor for changes: from service announcements to pricing tables, menus, or new blog posts.
Perch Intel automatically keeps tabs so you don’t have to.

Minimal, Distraction-Free Dashboard

View all your tracked competitors and recent changes on their page, in one streamlined dashboard.
No digging through spreadsheets or juggling multiple tools.

   Why It’s Different:
