Turn Every Browser Into a Productivity Powerhouse

What are web extensions and how can they help my business? Web extensions transform passive browsing into active value creation, turning browsers from display tools into intelligent assistants that work alongside your team on every website.
More than a SAAS tool: Your team lives in their browsers 6+ hours daily, yet browsers remain dumb display tools. Extensions turn passive viewing into active value creation.
Your team spends 6+ hours daily in their browsers. Reading content. Analyzing competitors. Managing campaigns. Researching prospects. But browsers are passive tools — they display information without helping you act on it. Web extensions change this, transforming browsers from viewing windows into intelligent assistants that work alongside your team.

The 20,000 User Success Story

Contra/Indy.ai Case Study: We built a 24/7 agent for freelancers that finds hidden opportunities across LinkedIn. Each user extends the network’s reach - like Batman’s surveillance network, the more users, the wider the net.

The Problem

  • Manual searching for leads takes hours - Good opportunities get buried in spam - Freelancers miss jobs while offline - Platform needed more stickiness

The Solution

  • Always-on agent finding personalized jobs - Distributed collection across 20,000 users - Each user’s browsing benefits everyone - Paradigm shift from manual to automated
The Network Effect: More users = wider reach = more opportunities found = better value for everyone. Contra under-promised and over-delivered - creating true value that made freelancers more loyal to the platform.

What Are Web Extensions?

What can web extensions do that regular software can’t? Extensions work where your team already spends 6+ hours daily - directly in the browser. They can read, modify, and enhance any webpage while automating repetitive tasks seamlessly.
Web extensions are programs that extend browser functionality, operating directly where your team already works. They can:
  • Read and modify any webpage
  • Inject intelligence into existing platforms
  • Automate repetitive browser tasks
  • Extract and process information in real-time
  • Connect web data to your business systems
  • Work silently in the background
Think of them as giving your team superpowers on every website they visit.
