Question: I'm looking for a platform that aggregates startup ideas from online communities, can you suggest one?

For harvesting startup ideas from online forums, IndiePulse is a great option. It mines more than 50,000 posts on relevant subreddits and offers more than 5,000 vetted startup ideas. The service offers customizable alerts, expert analysis of emerging trends and detailed market analysis. It's geared for indie hackers who need to keep up with industry developments rapidly, with pricing levels for free access to premium features.

Another contender is Feedbackbyai, an AI-based service that validates business ideas with reports that include market analysis and a step-by-step launch plan. It also uses AI interviews to uncover unknown concerns, so entrepreneurs can avoid wasted time and effort. The service is good for people who want quick validation and strategic insight without having to do a lot of market research.

For something more interactive, RedditChatLab uses chatbots to generate business ideas based on recent posts and comments on subreddits. It automates user research and offers suggestions for go-to-market strategies, so entrepreneurs and business developers can save time and hassle. The premium version offers weekly updated data and unlimited chats for a relatively low price.
