Firn

2026-10-16 / projects/firn.mdx

From a single sentence to a finished story. A narrative studio where scattered story material settles into canon — then ships as a book, comic, manga, webtoon, audiobook, or playable visual novel.

Firn is an AI-first narrative studio. It was called Kindling until July.

Firn is the stage between snowfall and glacier — loose snow compacting into something permanent. That's the product: scattered ideas, characters, and scenes settle into canon, and canon becomes something you can ship.

How It Works

You talk to Koda, the coordinator, and choose how involved it gets — Backseat, Co-writer, or Autopilot. Koda routes work to five specialists:

  • Storyteller — the only one allowed to change canon.
  • Writer — scenes, dialogue, chapter prose.
  • Illustrator — characters stay recognisable across hundreds of images.
  • Designer — pages and panels for Western comics, right-to-left manga, and vertical webtoons.
  • Editor — continuity: plot holes, name drift, timeline contradictions.

The pipeline runs outline → characters → world → draft → illustrate → layout → review, and stops at five checkpoints for you to approve before it moves on.

Since May

  • A real studio (Jun). Three modes: Make for writing, Know for the Codex — a browsable graph of characters, places, and rules that replaced the old Story Bible — and Read, with listen-along audio.
  • Writer tools (Jun). Scene board, plot grid, codex graph, mood-board canvas, research panel, and progress tracking.
  • Reveal Ladder. Mysteries reveal in order instead of leaking in chapter two.
  • Visual-novel studio (Jul). Branching editor, playable in-app preview, sprite sets with expressions, planned decision points, multiple endings, and on desktop a "Play now" that launches the game in Ren'Py.
  • StyleAnchor. One art direction applied to every asset in the project.
  • Audiobooks and fixed-layout comic EPUBs.
  • Bring your own book (Sep). Import a finished manuscript and keep building on it.
  • The rename. Kindling became Firn in July, along with a glacial-blue identity and rebuilt How-it-works, Formats, and Studio pages using real screenshots.

Why It Sits Near Sundog

Both ask the same question: how does a creative AI tool keep a world coherent instead of generating pretty fragments? Sundog answers it for games with a structured design doc and playable kits. Firn answers it for stories with the Codex. Same idea, different clothes.
