Startup Idea Validator — Free AI Tool That Scores Your Idea

Paste your idea. Get a defensible score, not a vibe check. Market size, competitors, economics and risks — cited and exportable in 60 seconds.

Quick answer

A startup idea validator is a tool that evaluates a business idea against market, competitive and financial evidence and returns a structured score instead of an opinion. StartupDeckAI's validator accepts a plain-language idea or an uploaded document, then returns a 0–100 score across six dimensions with citations, competitor data, TAM/SAM/SOM and an exportable investor memo — free for your first validation.

What a startup idea validator should do

Most 'idea validators' are a prompt wrapped in a landing page: they return confident prose with no sources, no numbers, and no way to check the work. A real validator has to be auditable. Every number needs a source, every competitor needs a URL, and every score needs a visible rubric you can argue with.

How the StartupDeckAI validator scores an idea

The validator scores six dimensions independently — market opportunity, competitive landscape, unit economics, execution and team-market fit, timing, and investor attractiveness — then combines them into a composite 0–100. Because dimensions are independent, a weak score tells you precisely what to fix rather than that the idea is 'bad'.

Text idea or uploaded document — both work

You can describe the idea in a sentence, answer the guided intake, or upload an existing deck, memo or notes as PDF, DOC, DOCX, TXT, MD or RTF. Uploaded documents are parsed and mapped onto the intake automatically, so the validation starts from what you have already written.

What you get back

A structured report: validation score with per-dimension breakdown, bottom-up TAM/SAM/SOM, a competitor map with feature gaps and pricing, unit-economics scenarios, top risks with mitigations, a 30-day next-step plan, and an investor-ready memo you can export.
