IdeaFast is best for
- You have an audience in mind and want to know what frustrates them, in their own words
- You want each problem linked to the post it came from rather than an aggregate
- You are choosing between ideas and want evidence one problem recurs more than another
IdeaFast is not ideal for
- You want to find the podcasts, newsletters and accounts your audience follows. That is SparkToro's job, not ours
- You need audience demographics or channel-level reach data
Is SparkToro a competitor to IdeaFast?
Not really, and it is worth saying so plainly rather than pretending otherwise for the sake of a comparison page. SparkToro describes its mission as making it easy to discover the websites, blogs, podcasts, social accounts and publications that reach your audience. That is a distribution question.
IdeaFast is a research question: given a group of people, what do they repeatedly complain about, how badly, and where is the evidence. The two get used at different points. SparkToro helps once you know what you are selling. IdeaFast helps before that.
What does IdeaFast do that audience research does not?
It reads the complaints rather than the channels. You point it at a community and it clusters recurring problems, scores each one for how often and how severely it comes up, and links every claim back to the original thread so you can read the person in their own words.
That output is narrower than SparkToro's by design. It only covers Reddit, and it only answers what is wrong, not where people are.
Can you use both?
Yes, and that is the honest answer for most people. Use IdeaFast to work out which problem is worth solving and to gather the language real people use for it, then use SparkToro to find where those people already spend their attention so you know where to show up.
Frequently asked questions
Is IdeaFast a SparkToro alternative?
Only partly. SparkToro is audience and channel discovery: which sites, podcasts and accounts reach a group of people. IdeaFast is problem research: what that group repeatedly complains about, scored and linked to the original Reddit threads. If you specifically want channel discovery, SparkToro is the better tool.
What does IdeaFast cover that SparkToro does not?
Recurring problems from a community, clustered and scored by how often and how badly they come up, with every claim traceable to the thread it came from. It is Reddit-only and deliberately narrow.
Which should I use first?
IdeaFast if you have not settled on what to build, because it tells you which problem is real. SparkToro once you know what you are selling and need to work out where to reach buyers.
Is there a free way to try IdeaFast?
Yes. Your first scan is free with no card, and a large amount of already-scanned research is published on the site with no signup at all.
