📌 What is TabCost?

TabCost turns your inactive tabs into a real economic metric. It's not just a tab manager: it's an attention auditor that assigns a monetary value to the time you lose.

  • ✅ Become aware of how much money "slips away" with forgotten tabs.
  • ✅ Automatically close what you don't use (Pro).
  • ✅ Export inactive tabs to CSV (Pro) to analyze habits.

🎯 Who is it for?

  • Freelancers charging hourly to minimize distractions.
  • Students & professionals needing concentration.
  • Remote teams improving productivity.

⚙️ How is the cost calculated?

Cost per minute = (Hourly rate ÷ 60) × Impact percentage

  • Default impact 20% (adjustable Pro). Active tab never generates cost.
  • Example: $50/h → ~$0.166/min per inactive tab.
