Constellationby Anklebreaker Studio

The constellation editor
for game design teams.

One place to write, link, simulate and ship every design doc across every project in your studio. GDDs that talk to each other. AI that reads them all.

Why now

Game design notes don't live in pages.

They live in connections. Mechanics shape systems, systems shape narrative, narrative shapes audio. A flat doc tool flattens those connections — and your team pays the cost in lost intent.

01
Documents that link, not pile up
Every doc is a star. Every link is an edge. The shape of your design is visible at a glance.
02
Cross-game by design
Glyph libraries, accessibility pillars, build pipelines — shared docs are first-class citizens, not Confluence copy-paste.
03
AI that read every doc
Ask the studio AI to find contradictions, draft missing sections, or propose a new doc. It cites which siblings it used.
Features

Everything a design lead asked for.

Nested constellations
Clusters of clusters. Combat → Melee → Parry Window — three taps, no breadcrumb soup.
Rich documents
Headings, callouts, tables, todos with assignees, embeds, references — and editable spreadsheets.
Spreadsheet docs
Tune drop rates and pacing in live cells. Σ totals recompute. Export to CSV.
Studio AI
Context-aware chat per doc and per cluster. Summarise, find gaps, generate.
Version history
Every save is a star pulled back. Diff lines tell you what moved.
Comments & threads
Anchored to text, resolved with one click. No more "search PDF for that thing Lea said".
Roles & permissions
Per-game scope, per-doc overrides, time-limited guests, full audit trail.
Export everywhere
Markdown, JSON, CSV, PDF. Pipeline-ready. Sign-and-timestamp on every export.
We had design docs spread across Notion, Confluence, Google Docs, and one cursed Word file. Three weeks after switching, our last "where is that doc" message in Slack was sent. We replaced six tools.
