Multi-Chart Sessions
Real astrological work rarely involves a single chart. Chaldea's session workspace lets you load multiple charts, overlay transits, and have the AI reference everything simultaneously — like having an expert astrologer with every chart spread across the desk.
Your Astrology Research Desk
In a Chaldea session, you can load up to 4 charts simultaneously. These can be natal charts, event charts, composite charts, or any combination. The AI sees all of them — and can reference any chart in context when answering your questions.
This transforms Chaldea from a single-chart reader into a full research environment. Compare two natal charts for synastry. Load a natal chart alongside a solar return. Put an election chart next to the natal chart of the person electing it. The possibilities are limitless.
What You Can Do
Synastry Analysis
Load two natal charts and ask about the relationship. Chaldea doesn't just compare sun signs — it examines cross-chart aspects, house overlays, ruler connections, and sect compatibility. It checks whether one person's benefic is the other's malefic of sect, whether rulers of the 7th cross-activate, and how each person's Time Lord periods align.
Transit Overlays
Overlay current or future transits on any loaded chart. The AI doesn't just list transits — it filters them through the chart's profection year, Time Lord periods, and natal configurations to show which transits actually matter right now.
Solar Returns
Load a natal chart alongside its solar return for the current year. Chaldea analyzes the solar return in the context of the natal chart — checking the condition of the natal planets in the return, the return Ascendant's relationship to the natal chart, and how the year's themes connect.
Composite Charts
Generate and analyze composite charts for relationships. The composite chart represents the relationship itself as an entity, and Chaldea reads it with the same depth it brings to any natal chart.
Mundane Comparisons
Compare mundane charts (ingress charts, eclipse charts, national charts) alongside natal charts to explore how collective transits affect individual lives. This is how traditional mundane astrology operates — the general sets the stage for the particular.
AI in Context
The key differentiator is that Chaldea's AI sees all loaded charts simultaneously. You don't have to manually cross-reference. Ask "How does her Saturn affect his 7th house?" and the AI already has both charts in context. Ask "What transits this month are most relevant for our relationship?" and it synthesizes transit data with both natal charts and the composite.
This multi-chart awareness makes conversations natural. You can reference any chart by name — "Look at Chart B's 10th house ruler" — and the AI follows along.
Session Persistence
Sessions persist. You can come back to a session later, and all your charts, conversation history, and context are preserved. Build up a detailed analysis over multiple conversations. Add charts as needed. It's an ongoing workspace, not a one-shot interaction.
Designed for Depth
Multi-chart sessions are designed for people who take astrology seriously — whether you're a student learning synastry, a professional comparing client charts, or an enthusiast researching your own relationships and timing. Chaldea gives you the tools to go as deep as you want.
