Explicit causal edges
Represent a claim that one event caused another or changed a fact.
For cause, consequence, and change
Causal timeline software for tracing what led to what.
Chronal Studio is causal timeline software for writers, researchers, and investigators who need to model both when events happened and how one event or condition is claimed to lead to another. It displays causal claims separately from ordinary relationships and keeps them connected to their source records.
Chronological order is not the same as cause and effect.
Two events can occur next to each other without one causing the other. A useful causal chronology needs to show sequence, distinguish relationships from causal claims, and preserve the evidence or authored source behind each claim.
- Which earlier events are claimed to have produced this outcome?
- What state changed because of a selected event?
- Which source supports this causal link?
Build a chronology whose reasoning can be inspected.
Chronal combines dated events, state changes, and explicit causal edges. Each view reads the same reviewed information, so the timeline and causal graph do not drift into separate versions of the project.
- 01
Record events and changes
Capture what happened, when it happened, and which project state changed.
- 02
State the causal claim
Link a cause to an effect explicitly; do not rely on visual proximity or sequence alone.
- 03
Inspect the chain and source
Follow the directed graph, return to the chronology, and open the supporting record.

More than events arranged on a line.
Chronal Studio is a desktop temporal reasoning workspace for modeling events, state, knowledge, causality, and change over time.
State through time
Calculate which facts, knowledge records, and relationships applied at a selected moment.
Separate relationship views
Explore general connections without silently treating every link as causation.
Source tracing
Open the record behind an answer, see when it applied, and inspect what it replaced.
Reusable investigations
Ask a guided or precise question and save useful investigations with the project.

Direct answers about this workflow and where Chronal fits.
What is causal timeline software?
Causal timeline software combines chronology with explicit claims about which events or conditions led to other events or changes. Chronal keeps these claims distinct from ordinary relationships so they can be inspected rather than inferred from proximity.
Does Chronal decide that one event caused another?
No. Chronal records and visualizes causal claims supplied or approved by the user. It helps you inspect those claims and their sources; it does not prove causation automatically.
Can Chronal show both relationships and causality?
Yes. Chronal provides a general relationship view and a separate cause-and-effect view. This prevents a connection between two records from being mistaken for a causal claim.
Can I trace a result back to evidence?
Chronal keeps source information with approved facts and events. A source trace can show where an answer came from, when it applied, and which earlier record it replaced.
