IdeaFast is best for
- You are still deciding what to build and want evidence a problem is real and repeated
- You want problems clustered and scored rather than individual posts ranked
- You want to read the original threads behind every claim
IdeaFast is not ideal for
- You want posts scored by buyer intent so you can reply to them. That is Subreddit Signals' job
- You want a done-for-you Reddit lead service, which they offer and we do not
Is IdeaFast a Subreddit Signals alternative?
Not for the job most people are searching for. Subreddit Signals is about finding Reddit conversations worth joining, prioritised by fit and buyer intent. IdeaFast never surfaces a post for you to reply to, and has no notion of buyer intent.
What it does instead is read a few hundred posts from a community and group the ones describing the same underlying problem, then score each group by how often and how badly it recurs.
Different questions, different stages
Buyer intent only means something once you have something to sell. If you already do, a lead tool is the right instrument and this is not it.
If you are earlier than that, ranking posts by intent tells you very little, because the useful question is not who is ready to buy but what is worth building at all.
What the scored output looks like
A ranked list of recurring problems, each with a score from 0 to 100 for how acute, frequent and recent it is, and a set of real threads underneath it that you can open and read. You can see the shape of it on the published research pages without signing up for anything.
Frequently asked questions
Does IdeaFast score posts by buyer intent?
No. It scores recurring problems by how often and how severely they come up across a community, not individual posts by purchase readiness. Subreddit Signals does the buyer-intent ranking.
Can IdeaFast find me Reddit conversations to reply to?
No. It has no engagement, outreach or reply features. It is research only.
Which is right for me?
If you have a product and want customers, a lead tool like Subreddit Signals fits. If you are still deciding what to build, IdeaFast is aimed at that question.
Is there a free way to judge the output?
Yes. Research for dozens of communities is published free on this site with no signup, and your first scan is free.
