Smart Rules That Organize Your Time Automatically
Stop manually categorizing every activity. Chronoid's rules engine, ML classifier, and AI suggestions automatically assign your tracked time to the right projects and categories — so your data is always organized.
How Smart Rules Work
Define Your Conditions
Create rules using conditions like app name, window title, URL, or document name. Combine multiple conditions with AND/OR operators for precise matching.
ML Learns Your Patterns
Chronoid's built-in FastText classifier learns from your categorization history. Over time, it automatically suggests the right project for new activities.
Activities Auto-Categorize
New activities are instantly matched against your rules and ML model. Everything lands in the right project without you lifting a finger.
Key Benefits
Flexible Condition Builder
Match activities by app name, window title, URL, or document path. Use contains, starts with, regex, and other operators to build precise rules.
ML-Powered Classification
A local FastText machine learning model trains on your categorization patterns. The more you use Chronoid, the smarter it gets at auto-assigning projects.
AI-Powered Suggestions
Get intelligent rule suggestions based on your uncategorized activities. Chronoid identifies patterns and proposes rules you can accept with one click.
Retroactive Application
New rules don't just apply going forward. Apply rules retroactively to recategorize past activities instantly, keeping your entire history organized.
Common Rule Examples
"When app is Xcode → assign to iOS Development"
Automatically categorize all coding time by the IDE you're using.
"When URL contains github.com/acme → assign to Acme Project"
Route browser activity to the right client project based on the URL.
"When window title contains 'Invoice' → assign to Accounting"
Match document titles and window names for precise categorization.
"When app is Figma AND title contains 'Redesign' → assign to UI Redesign"
Combine multiple conditions with AND/OR for granular control.
Frequently Asked Questions
How does the ML classifier work?
Chronoid uses a local FastText model that trains on your categorization history. It runs entirely on your Mac — no data is sent to the cloud. The model continuously improves as you categorize more activities.
Can I apply rules to past activities?
Yes! When you create a new rule, you can choose to apply it retroactively to all matching past activities. This is perfect for organizing historical data you've already tracked.
What happens when multiple rules match?
Rules are evaluated in priority order. You can drag and drop to reorder rules, ensuring the most specific rules take precedence. The first matching rule wins.
Do I need to set up rules manually?
Not necessarily. The AI suggestion engine analyzes your uncategorized activities and proposes rules automatically. You can review and accept suggestions with a single click, or create custom rules from scratch.
