The honest verdict
These two are both active, so this is a real choice rather than a historical one. PainOnSocial is the more focused of the two: a library of pre-generated pages surfacing recurring Reddit pain points, built to be skimmed. Its strength is simplicity and a Reddit-centered view, which is exactly what many founders want in the earliest, most exploratory phase of looking for something to build.
BigIdeasDB is broader in almost every dimension. It pulls complaints from G2, Capterra, App Store reviews, and Upwork alongside Reddit, claims over 238,000 analyzed complaints across roughly 1,000 categories as of July 2026, and layers on build-oriented tooling (BuildHub for project management, BuildGuide, and an MCP server). It is sold as a one-time lifetime purchase. The trade-offs are that its quotes are AI-summarized rather than linked to a specific discussion, and the deeper analysis on its free pages sits behind a signup.
The honest verdict: pick PainOnSocial if you want a lightweight, Reddit-focused library to browse for inspiration. Pick BigIdeasDB if you specifically need multi-source breadth (review sites and job boards, not just Reddit) and the extra build tooling, and you are comfortable with lifetime pricing and summarized, gated evidence. Neither is strictly better; they weight breadth versus focus differently.
Where IdeaFast fits
A third option, in the interest of full disclosure
Full disclosure: IdeaFast is our own product, so read this with that in mind. Both tools above ask you to trust a written-up or AI-summarized version of the underlying complaints. PainOnSocial presents grouped pain points to read; BigIdeasDB attributes summarized quotes to a source category rather than a clickable thread.
IdeaFast is built around the opposite default: every pain point links directly to the original Reddit or Hacker News discussion, so the evidence is something you verify rather than take on faith. It clusters complaints with an embedding pipeline (so a theme's quotes always match it), scores each theme from 0 to 100, and turns the strongest into validated startup ideas. It is a monthly subscription you can cancel anytime, the research pages are readable without signing up, and the first scan is free. If verifiable evidence and scoring matter more to you than the widest source list, that is the trade we made.

Does either link to the original complaint?
PainOnSocial presents written-up grouped pain points, and BigIdeasDB attributes AI-summarized quotes to a source category rather than a specific clickable discussion. IdeaFast (our product) links every pain point to the original thread.
Which should I pick for a niche I already know?
