FAQ

Common questions about Preuve AI vs IdeaBuddy

What is the main difference between Preuve AI and IdeaBuddy?

They solve different problems. IdeaBuddy is a business planning tool - business plan, financial projections, investor-ready documents. Preuve AI is a market validation tool - it scans 50+ live data sources to test whether the opportunity is real before you invest time planning. The two are complementary, not competing.

Does IdeaBuddy validate startup ideas?

IdeaBuddy includes a validation module in its feature set. It relies on founder inputs and AI assistance rather than live market data. Preuve AI pulls from 50+ live sources (Crunchbase, Google Trends, Reddit, Product Hunt, G2) and links every claim to its origin so you can check the data yourself.

Can I use both tools together?

Yes, and that is often the right sequence. Use Preuve AI first to check whether the market opportunity is real - demand signals, competitor landscape, TAM/SAM/SOM with live data. If the numbers look solid, use IdeaBuddy to build the business plan, financial projections, and investor documents around a validated idea.

Which tool is better for investors?

It depends on what the investor is asking for. Preuve AI gives you due diligence evidence - source-linked competitor data, market sizing with citations, risk analysis from live sources. IdeaBuddy gives you polished business plan documents with financial projections. Some founders use both: Preuve AI for the evidence, IdeaBuddy for the presentation layer.

Is IdeaBuddy free?

IdeaBuddy offers a 15-day free trial with no credit card required (1 idea, 1 collaborator, 10 AI requests). After the trial, paid tiers unlock more ideas, collaborators, and features. Preuve AI offers a permanently free viability scan with no time limit.
