Chronal StudioComing soonLocal-first desktop app

Your notes tell the story. Chronal shows what changed.

Write in ordinary Markdown. Review the people, events, dates, and changing facts Chronal finds—then explore them as a timeline or graph without losing the source.

Start with the workflow, not the terminology.

When the latest note is not the whole answer

Projects become difficult when their truth changes over time.

Stories, investigations, research, and long-running notes accumulate revisions, conflicting accounts, decisions, and consequences. Search can find a phrase. It cannot tell you which answer was true on a particular date or why it changed.

  • What was true before the latest update?
  • Who knew what, and when did they know it?
  • Which event changed the answer—and which note proves it?

Write normally.
Add structure deliberately.

Chronal leaves prose readable and puts structured changes through review. You stay in control of what becomes part of the project.

  1. 01

    Start with the writing

    Keep notes, scenes, records, and research in ordinary Markdown files inside a local folder.

  2. 02

    Review what Chronal finds

    Inspect proposed facts, dates, events, and relationships. Revise, accept, or reject each change.

  3. 03

    Explore what the writing means

    Move through time, follow the graph, and trace every answer back to the prose that supports it.

Built for work where yesterday’s answer still matters.

Chronal makes change explorable whether you are maintaining a fictional world, reconstructing events, or keeping years of connected notes coherent.

Understand the answer. Keep control of the project.

Know what was true.
Trace why.

Local AI is always local, always reviewable, and always optional. Chronal’s core writing, timeline, graph, and source-tracing workflows do not require a model.

Read the AI and agent boundaries

Your files remain the foundation.

Projects are ordinary local folders with readable notes and small data files for the structure you approve.

Nothing is accepted silently.

Suggestions remain proposals until you review them. Editing the prose stays normal authoring.

Every answer keeps its trail.

See the source, the applicable time, and the earlier information a newer fact replaced.

Know what was true. Trace why.

Follow the Greyhaven workflow from ordinary writing to a time-aware answer with its source still attached.
