AI — "Thoughts"

Thoughts is the built-in AI assistant. It:

• Parses natural language to detect tasks, dates, priorities
• Creates tasks and calendar events from plain text
• Analyzes journal entries for mood patterns
• Gives productivity recommendations

It uses the Claude API when ANTHROPIC_API_KEY is set, and falls back to a built-in rule-based engine automatically when the API is unavailable.

Data

All data is stored locally in your browser via localStorage. Nothing is sent to external servers (except your messages to the Thoughts AI endpoint if you configure a Claude API key).

Use the Export page to download your data as JSON.
