Subject: New Commuter Benefit Program Now Available Hi Team, I'm excited to announce the launch of our new commuter benefit program, effective immediately. This benefit is designed to support employees who use public transportation or bicycles for their commute while providing tax advantages to both you and the company. Here's what's included: **Transit Benefits:** We'll help you cover costs for buses, trains, and other public transportation. You can set aside up to $315 per month (2024 limit) pre-tax, reducing your taxable income. **Bike Benefits:** If you bike to work, you can allocate up to $35 monthly for bicycle maintenance, repairs, and gear through our bike benefit program. **How It Works:** All benefits are deducted pre-tax from your paycheck, which means lower taxes and more money in your pocket. Simply enroll through our benefits portal or contact HR for assistance. **Eligibility:** This benefit is available to all full-time and eligible part-time employees. Enrollment is open now, and benefits can begin as soon as next month. **Next Steps:** Visit the benefits portal starting tomorrow to enroll, or reach out to HR with any questions.

We hope this program makes your commute easier and more affordable. Questions? Contact HR at benefits@company.com. Best regards, [Your Name]

How to read these scores

Each detector's result is converted to a human-likelihood score between 0 and 1. A score of 0 means the detector is sure the text is AI. A score of 1 means it is sure the text is human. Dots are green at 0.50 or above and red below. Hover a dot to see its exact score. The 0.50 cut-off only sets the dot colors. A tool's bypass rate on the leaderboard takes the median of the 7 detector scores for each test, then averages those medians. That gives a continuous number, so it will not match the share of green dots. The same goes for each per-detector rate. It is the average of that detector's scores (the number detector pages rank by), not a count of green dots.
