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.

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.

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.
