Start with one question
Nexus Historia offers ways to explore history and imagined alternatives. Start with a narrow question: what changes if a particular decision is different?
In Create, establish the baseline before describing the divergence. An alternative outcome is a hypothesis, not a prediction or a newly discovered fact.
Build and review
Scenario and storyboard tools help turn an idea into text and visuals. Review the result for consistency and check historical details against reliable sources. Generated images and dialogue should remain clearly identified as interpretations.
Living Timelines let you develop branches from an idea. Before sharing anything, check its visibility and public-sharing settings. Keep personal information out of public creations.
Explore other experiences
Browse the gallery for public work or Historical Worlds for the immersive experiences. Storyboard narration and a scheduled multiplayer world tour are different features; use the relevant page for its controls and requirements.
Costs and access
Use Credits and the price displayed by the tool before generation. This post no longer carries an old fixed price list. Consult the FAQ for current access guidance, including the distinction between the general app and educational arrangements.
A useful first project is small enough to check: one turning point, a few consequences and a short list of sources.
Editorial review
Reviewed on 26 September 2026. Updated product guidance against the current implementation; removed unsupported guarantees, obsolete specifications and unverified roadmap promises. Removed the legacy cover because its licence/provenance was not established by the available records; the original is retained in the review backup.
