Color-code Google Calendar events for timeblocking and time tracking

Helps users organize their time visually in Google Calendar through color coding, enabling better time management, timeblocking, and time tracking without leaving the Google Calendar interface.

User installs extension, grants Google Calendar permissions, opens Google Calendar, presses 'T' to open the Chalk panel, then uses the panel to color-code events, assign custom labels to colors, and track time spent per color category.

Target users: Professionals using Google Calendar for time management / Freelancers needing time tracking for invoicing / Users interested in timeblocking techniques

The extension bundles large minified JavaScript files (content.bundle.js is ~3.4MB), making static analysis of specific logic challenging without decompilation. However, the manifest and external API calls provide sufficient evidence for the main decisions.

Monetization

No paid features detected

No evidence of paid features, subscriptions, or payment processing in the extension code. The keyword matches for 'pro' and 'license' are from bundled libraries (React, Moment.js) and not related to the extension's own monetization. The extension description does not mention any paid tiers or premium features. The privacy policy URL points to chalkproductivity.com, but there's no indication within the extension that it gates features behind a paywall.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension requires Google Calendar access to function. The manifest declares OAuth2 scopes for userinfo.email, userinfo.profile, calendar.readonly, and calendar.events. The content script runs on calendar.google.com. While the extension itself doesn't implement a separate login UI, it relies on the user being signed into their Google account and authorizing the extension's access to Google Calendar data. Without a Google account and authorization, the core functionality (color-coding calendar events) cannot work.
