Docs

Getting started

Two paths into Lunastak. Either generates a Decision Stack.

Start in the app

The fastest way to get started. Bring one or two docs, talk it through, get a draft.

  1. Sign up at app.lunastak.io. No card. The free tier covers a first conversation, draft stack, and three document imports.
  2. Answer four to six questions about your vision, the choices you're making, the metrics that matter, and your operating principles.
  3. Luna drafts a Decision Stack from your answers. Refine with follow-up turns or document uploads.

Start in your own LLM client

More powerful. Unlimited docs, your conversation stays in your LLM, plus export and resume.

Use the Decision Stack skill in Claude Code, a Gemini Gem, or a Custom GPT to extract strategic context from your existing material — decks, docs, transcripts, notes. The skill produces a context bundle: a JSON file.

Import the bundle at app.lunastak.io and Luna generates the stack from it.

Picking a path

  • Starting fresh, talking it through? Start in the app.
  • Existing material to consolidate? Start in your LLM client.
  • Both? Prepare context in your LLM client, then refine in the app.
