Loom

ActiveLacunae

A canvas where stories branch. Write prose, wire scenes, export and play.

Loom is an authoring tool for the kind of interactive fiction Perpetūra is made of: literary, choice-driven, character-first. The goal is to let anyone craft that kind of story, not just read one.

The editor is visual: scenes are nodes on a map, connections are drawn by hand, chapters collapse the map to a manageable view. The prose layer supports conditional branches and flag interpolation inline, so the writing and the logic stay in the same place. When a story is ready, export produces a single HTML file that plays in any browser.

Local-first by design. No cloud dependency, no account, no subscription. Your words stay on your machine until you choose to share them.

VISUAL STORY MAP

Drag-and-drop node editor with auto-layout, minimap, and chapter grouping. See the whole shape of a story at once, not just the scene you are in.

CONDITIONAL PROSE

Branch mid-paragraph with [if cond]…[else]…[/if] and {flag} interpolation. Logic lives inline with the writing, not in a separate scripting layer.

OWN YOUR WORDS

Stories live on your machine as project files. Export is a single, self-contained HTML file. No account required, no server, playable anywhere.

PLAYER CODEX

Unlockable reader entries that fill in as you progress. Worldbuilding revealed through reading, not front-loaded in a glossary.

IN-APP PLAYER

Test and play stories without leaving the editor. What you see is what readers get.

BUILT ON PERPETŪRA

Dogfooded on the full 66-scene Hyunjae story. Every rough edge in the editor was found through real authoring, not hypothetical use.
