FAQ
Common questions about Preuve AI vs IdeaBuddy
What is the main difference between Preuve AI and IdeaBuddy?
They solve different jobs. IdeaBuddy is a business planning tool - it helps you build a business plan, financial projections, and investor-ready documents. Preuve AI is a market validation tool - it scans 40+ live data sources to test whether the market opportunity is real before you invest time planning. Planning and validation are complementary, not competing.
Does IdeaBuddy validate startup ideas?
Yes, IdeaBuddy includes a validation module in its feature set. However, it relies on founder inputs and AI assistance rather than live market data sources. Preuve AI pulls from 40+ live sources (Crunchbase, Google Trends, Reddit, Product Hunt, G2) and links every claim to its origin so you can verify the data yourself.
Can I use both tools together?
Yes, and this is often the ideal sequence. Use Preuve AI first to validate the market opportunity - check demand signals, competitor landscape, and TAM/SAM/SOM with live data. If the market looks real, 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 needs. Preuve AI provides due diligence evidence - source-linked competitor data, market sizing with citations, and risk analysis from live sources. IdeaBuddy produces polished business plan documents with financial projections. Some founders use both: Preuve AI for the evidence, IdeaBuddy for the presentation.
