IdeasAI is a free, endless stream of AI-generated startup ideas — every single concept on the site is produced by AI and refined by the votes of more than two million visitors.
Created by indie maker Pieter Levels (of PhotoAI and InteriorAI), IdeasAI is now powered by xAI’s Grok models, which generate new startup ideas continuously — the site reports over 52,000 ideas generated so far. Visitors swipe through ideas, liking the promising ones and disliking the duds, and that feedback is fed back into the model so the generator keeps learning what a good idea looks like. Leaderboards surface the top ideas of the day, week, month, and all time, making it a popular source of inspiration in the indie hacker community.
The charm of the site is its honesty: the AI generates ideas with no human curation at all, so the stream mixes genuinely clever concepts with gloriously bad ones — and the community voting layer is what separates signal from noise. Two million-plus voters have trained the generator over the years, and the all-time leaderboard has become a small museum of ideas that later turned into real products. A weekly newsletter delivers the highest-voted new ideas to more than 89,000 subscribers, which makes IdeasAI as much a trend-watching habit for founders as an idea source.
IdeasAI is completely free to browse and vote; the weekly top-ideas email is free too. The site is supported by advertising.
IdeasAI is for aspiring founders and indie hackers who are between projects and want a daily spark of inspiration — a low-effort way to spot unusual opportunities before they become obvious.
