Start from a customer problem you can reach and a format that fits your time, then test demand, competitors and unit economics on live data before you build anything. The steps below link to the pages and tools for each stage.

Decide how much time and money you can put in, then open the collection that matches it, such as online or side hustle ideas. A side project and a full-time startup need different ideas.
Tell Fox your skills, budget and the customers you know, and it suggests AI ideas that fit. Keep three or four candidates you could sell to people you can actually contact.
Estimate how many buyers have the problem and what they pay to solve it today. If the market is too small for your income goal, drop the idea now.
Put model usage fees, hosting and support time per customer against your price. An AI product that costs more to serve than it earns per user fails no matter how many users it gets.
Run your top candidate through the validator before you write code or sign clients. It scores the idea out of 100 on nine axes, with a source for every figure.
AI is the one market of its own built so far. Next to it are the markets an AI business builds on: apps, websites, IT services and data centers.





Fox's real checks: a score out of 100, a verdict and a source for every figure. Open one and compare it with your version.
Your budget, town and time → ideas with a market under each.
It depends on whether you build on existing model APIs or train your own models, and on whether you sell a service or software. The main lines are usage fees per request, hosting, software subscriptions and your own time. Put your estimates into the unit economics calculator, and check the start costs with sources on the market page for your niche.
Choose a service business, such as setup or content work done with existing tools, if you don't code. Choose a software product only if you can ship and maintain it yourself or have a technical cofounder. The collections on this page include both kinds, so filter by the format that matches your skills.
We have not checked this idea yet, so test it before you commit. Look at state rules on the unauthorized practice of law, your liability when the tool gives a wrong answer, and whether small firms or small businesses will pay for it. The business idea validator checks demand, competitors, complaints and prices for the version you describe.
Many tools already turn podcasts and videos into clips and posts, so a general version competes with them on price. It has a better chance if you serve one narrow group of creators or sell a done-for-you service that the tools don't cover. Run your exact angle through the validator to see the competitors and the complaints their users leave.
Talk to a handful of likely buyers, check search demand for the problem, and read complaints about the tools they use now. Then ask for a preorder or a paid pilot at the price you plan to charge. The market analysis guide covers the research, and the validator puts it on live data with a score out of 100.
Model access through APIs lets you build a first version without training anything, so you can test with real customers quickly. The same access is open to every competitor, so your edge has to come from a customer group you know, your distribution or data others don't have. Start with an idea where you have one of those three, and check it with Fox before you build.
How we made this page. This page is our map of collections for AI business ideas: a card with a link is a page an editor has built and checked, and the others are planned. A market page holds demand from search data, the players, start costs from open sources with links, customer complaints and the ideas checked in that niche. An idea check tests one idea on live data across nine axes, including demand, competitors, complaints, prices and unit economics, and gives a score out of 100 with a source for every figure. Data as of 15 October 2026.
