IdeasAI

Endless AI-generated startup ideas, ranked by real people's votes

Swipe-to-vote idea feed

React to each card by swiping or using the left and right arrow keys, in the familiar dating-app gesture pattern.

Crowd-trained generation

The site reports how many people have voted and channels that feedback into which ideas the underlying model produces next.

Monthly, weekly and daily leaderboards

Dedicated sections for this month's, this week's, yesterday's and today's highest-voted ideas keep the best concepts visible as the feed churns.

One-click Build it links for each idea

Every idea sits at a stable URL with an upvote count, so you can revisit one later, share it with cofounders or bookmark it.

Strengths & Pros

+Crowd voting surfaces genuinely interesting ideas rather than serving a random stream
+Daily and weekly leaderboards turn the archive into a browsable, sortable list
