- IdeaProof
IdeaProof runs on credits: a validation costs 40, and you get 40 free when you sign up. It also writes business plans and makes brand identities and marketing assets. StartupDeckAI focuses on the validation report, with a label on every fact and a free validation every month.

New accounts start free, with no card. The first 7 days are a trial with 1 full idea analysis and 2 quick analyses. After that the Free plan gives you 1 full validation and 2 quick analyses a month, for as long as you like.

A launch kit, or a report you can check
IdeaProof is built to take an idea all the way to launch materials. After the validation you can spend credits on a business plan, a brand identity, landing page mockups and a set of marketing assets. Its analysis is done by AI from research, not by testing the idea with real visitors.
StartupDeckAI stops at the decision: is this idea worth building? It puts its effort into the report and into showing what each fact is based on, so you know what was found and what was estimated.
If you want the brand kit too, IdeaProof does more. If you want to validate often, our monthly free plan and flat Pro price are likely to cost less.
Questions
- Does IdeaProof test my idea with real customers?
- Not on the pages we read on 8 October 2026. Its validation is an AI analysis. It can generate landing page mockups and copy, but we did not see live traffic or survey tests described.
- Which costs less?
- It depends on how many ideas you validate. IdeaProof sells one-time credits, with a validation costing 40. StartupDeckAI has 1 free full validation a month, and Pro at ₹2,499/month for unlimited validations.
