Getting started

Two paths into Lunastak. Both end the same way: Lunastak shows you the ground truths it found in what you gave it, you review them, then you build your Decision Stack.

Start in the app

1. Go to app.lunastak.io. No account needed to start. A new project offers three ways in: Talk to Luna, Upload a document, or Import from AI. Uploading needs a free account.
2. Open Talk to Luna and answer three to ten questions. The chat follows your answers into the strategic areas they leave thin — customers, value, competition, economics and the rest. Watch a chat (video, opens in a new tab)
3. Lunastak shows the ground truths it took from what you said, each with the words it came from. Discard any that are wrong, then press Build my strategy. Watch a review (video, opens in a new tab)

Refine later with more chats or document uploads. Watch an upload (video, opens in a new tab)

Bring your thinking from any AI

Paste one line into any AI assistant (Claude, ChatGPT, Gemini, Claude Code…) and talk it through: share your decks, docs, transcripts and notes, and answer its questions. When you're done, it gives you a context bundle: a JSON file.

Import the bundle at app.lunastak.io. Lunastak adds the bundle's ground truths to your project and opens a review of them. Building the stack is a separate step: press Build my strategy when you're ready. Watch it, from paste to import (video, opens in a new tab)
