The Moonshot Test
Validate your startup idea against six proven frameworks — on the web or from the CLI. Get a scorecard with letter grades, a diagnosis of strengths and weaknesses, and three progressively bolder versions of your idea.
The Moonshot Test is a free AI idea-validation tool at brandstack.dev/tools/moonshot-test. Paste in your startup idea and get a structured assessment in seconds. No account required.
Run it from the command line
npx @brandstack/cli moonshot-test "An app that turns meeting notes into \
decisions, for remote product teams drowning in follow-ups."
npx @brandstack/cli moonshot-test --file idea.txt --jsonNo account, no API key — but network access is required: unlike every other free tool, the Moonshot Test’s logic runs on Brand Stack’s servers (the assessment comes from an AI model). The CLI calls the same public API the web page uses, under the same rate limit, and says so plainly if it’s offline. Ideas need to be 50–4000 characters.
What it evaluates
Your idea is scored against six classic startup frameworks:
| Framework | What it asks |
|---|---|
| Toothbrush Test | Do people use this every day? |
| Painkiller vs. Vitamin | Does it solve an urgent pain or a nice-to-have? |
| Why Now? | Why is this the right moment for this idea? |
| 10× Better | Is it meaningfully better than the alternative, not just marginally? |
| Contrarian Truth | What does this bet on that most people get wrong? |
| Massive Transformative Purpose | Does it have the potential to change an industry or the world? |
Each framework gets a letter grade (A to F) and a short explanation. The overall GPA gives you a quick read on idea strength.
What you get back
The assessment has six sections:
- Verdict: overall grade and a generated title for the bolder version of your idea
- What We Read: a summary of what the AI understood from your input, so you can spot any misreads
- Diagnosis: specific strengths and weaknesses anchored in your own wording
- Scorecard: letter grades for each of the six frameworks
- Elevation Levers: 3 to 4 named axes you can push your idea along to make it bigger
- Three Bolder Versions: escalating reframings of your idea, with the third being the full moonshot
Sharing your result
After you run the test, a Share button appears on the result. Sharing publishes your idea title, verdict, and assessment to the Moonshot Test community gallery. A shareable detail page is created at a unique URL you can send to collaborators or investors.
Your idea is saved privately by default. Only ideas you choose to share appear in the gallery.
Tips for better results
- Write 2 to 5 sentences. One sentence is too thin; a paragraph gives the AI enough to work with.
- Be specific about the customer. “For freelance designers who…” beats “For anyone who…”
- Include the pain. Describe what problem is being solved and why existing solutions fall short.
- Don’t worry about polish. The tool is designed to see through rough pitches and find the core idea.
For AI agents
Prefer the CLI with --json for the full structured assessment. Agents can also call the API directly: POST /api/tools/moonshot-test with a JSON body of { "idea": "<your idea, up to 4000 chars>" }. This page is also served as plain markdown at /tools/moonshot-test.md, and listed with instructions in /llms.txt.
Rate limits
The Moonshot Test is free and doesn’t require an account. To keep it available for everyone, it’s limited to 5 requests per hour per IP address — through the web page, the CLI, and the API alike.
