From signal to opportunity
Eureka reads across the places real demand shows up, then turns the raw signal into a researched opportunity with the context to evaluate it before you write a line of code.

How we keep it real
Most idea lists are AI-generated slop. Ours are mined from real demand, filtered hard, and then read one by one by our team. If it is not real, it does not make the database.
We read where real demand shows up: Reddit threads, popular tip and workaround posts, reviews, job boards, and regulatory shifts.
Targeted queries surface recurring, high-intent demand and the workarounds people already share by hand, not one-off venting.
Automated scoring strips out rants, duplicates, saturated categories, and thin AI-slop before a human ever sees it.
Every idea that survives is read and vetted by hand before it enters the database. If it looks like slop, it never ships.
