Changelog

December 2025

• 🎉 Network View: Visualize relationships between players in an interactive force-directed graph. See how parties, entities, and key players connect to each other at a glance. Click on any node to see their relationships and navigate to related events. The network view is fully connected to your timeline—select a player in the network to filter related events.

• 🎉 Split Timeline View: Create side-by-side juxtapositions of different event types. Configure top and bottom lanes with custom filters by category or player to compare parallel narratives—perfect for showing two sides of a dispute, separating correspondence from contracts, or any comparison that helps tell your story.

• 🎉 Data-Driven Views: Thea now works like Notion—your timeline data (events, players, relationships, exhibits, categories) is the single source of truth, and views are different ways to visualize it. The Data tab shows the underlying structured data, while Timeline, Network, and Split views each offer a unique lens on that same data. Edit in one place, see updates everywhere.

• 🎉 JSON Export: Export your complete timeline data as structured JSON. Includes events, players, relationships, and categories with all metadata—ideal for power users who want to process data externally, create custom visualizations, or integrate with other tools.

November 2025

• 🎉 Chat Source Verification: When chatting about timeline events, Thea now shows which documents were used to answer your questions. Click on any source to view the document, giving you full traceability for every chat response.

Upload Dutch documents and get Dutch timelines, no manual configuration needed. You can still override by asking Thea to "use Dutch" or "use English" in chat.
