AI product read

Calculate the estimated monetary cost of Google Calendar meetings based on configurable hourly rates and participant counts.

Helps users understand the financial impact of their meetings by calculating the approximate cost based on participant time value, enabling better time management and meeting efficiency decisions.

1. User installs extension and sets a custom hourly rate (default €11.65) stored in chrome.storage. 2. When creating or editing a Google Calendar event, the content script monitors the participant list. 3. User clicks the meeting duration field to trigger calculation. 4. Extension sends meeting duration and participant count to the background service worker. 5. Background calculates: hourly_rate × duration_hours × participant_count. 6. Result is displayed inline in the Google Calendar UI showing the estimated meeting cost.

Target users: Professionals managing team meetings / Consultants tracking billable hours / Project managers optimizing meeting efficiency / Anyone wanting to quantify the cost of their scheduled meetings

The extension is very small (version 0.0.1) with limited user base (23 users), so edge cases may not be fully covered.
The content scripts rely on Google Calendar's internal CSS class names (e.g., '.RDlrG.Inn9w.iWO5td') which may break if Google updates their UI.
No explicit testing of the extension's behavior in different Google Calendar views was performed.

Monetization

No paid features detected

The extension is entirely free with no paid features. It uses only chrome.storage for local settings (hourly rate). No payment APIs, subscription checks, license validation, or upgrade prompts were found in the codebase. The 'cost' mentioned in the description refers to calculating the monetary cost of meeting participants' time, not charging users for the extension itself.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension operates entirely offline/local. It uses chrome.storage.local for persisting the hourly rate setting and performs all calculations within the browser. No authentication flows, login buttons, or external API calls requiring credentials were found. The extension works with Google Calendar which requires the user to be logged into Google (browser profile), but this is a prerequisite of using Google Calendar itself, not a requirement imposed by this extension.
