AI business ideas you can build with Supabase

A playbook for AI products that need to stay useful when a new release from the AI company gives customers the same basic results in its own app. The hard part: spotting which parts of your product a platform vendor could ship next, and building around the workflow instead.

Decision models (fast AIs that only make yes/no or sorting calls) are cheap and fast, but early tests show real weak spots. Test them on 50-100 of your own cases before you build on them. The hard part: gathering enough labeled examples from your own data before you trust any benchmark.

If your product makes things people post in public, like video clips or images, put a small logo on everything made on the free plan. Each post then shows your tool to other creators, and paying removes the logo. The hard part: making output good enough that people post it even with your logo on it, in a space where many tools compete for the same creators.

Sort a small business's incoming emails and support tickets with a cheap AI that only makes sorting calls, and bring in a writing AI or a person only when needed. The hard part: selling the service and tuning categories so the decider stays accurate on each client's mail mix.

If your product already stores lots of real records, like user profiles or listed products, turn each one into its own page that can show up in Google search, and cut groups of pages that bring no signups. If your site is just one page, write a few articles that answer what buyers search for. The hard part: waiting months for Google to send visitors, then judging which groups of pages actually bring signups.

Pick one AI tool or trend that launched in the last 90 days, and run a website that collects real examples of how people use it: what they did, what they got, and the prompt they used. Sponsors, newsletter readers and affiliate partners pay. The hard part: getting visitors in the first place, because the example's traffic came from the owner's large X following, and then keeping the directory updated every day.

A small AI tool that reads an online store's customer reviews and turns them into product benefit lists, ad copy, and FAQ answers. Store owners pay a monthly plan. The hard part: standing out from the general AI writing tools store owners already use.

If you sell a one-time scan or report, build an ongoing version and email it to the people who already bought from you before you spend more on ads. These buyers have already paid once, so they are the most likely to pay every month. The hard part: building an ongoing version that is worth paying for every month, not just the one-time report again.

On a job board or directory, charge the readers who need the list fast, not the businesses you assume have money. Skip the free tier. The hard part: finding a market where one side is clearly more urgent than the other and will pay without a free tier.

Offer an AI tool free to users who connect their own AI account (their own API key, so they pay the AI company directly), and charge a monthly fee to those who use yours. The hard part: making the paid tier feel worth it when the free own-key path already works.

Build a tool other apps pay to use that does one boring developer job, charge by how much it's used, and use a free single-use tool page to bring in developers. The hard part: ranking a free tool page high enough to feed steady paid API usage.

Founders who launch a product submit the same details to nearly 200 launch directories. Sell them a browser add-on that fills each form in one click and keeps the directory list current, with an optional done-for-you service. The hard part: keeping almost 200 directory forms working as sites change, and competing with a free extension that already does the basics.

A monthly tool that keeps asking AI assistants the questions buyers ask and reports whether a business's brand gets recommended. Small brands pay to see whether they are being left out of AI answers. The hard part: standing out from similar trackers and showing brands what to do with the results.

Set up an AI that visits local permit websites every day for builders, remodelers, and pool and solar installers, and tells them when a permit's status changes, so nobody has to refresh city sites by hand. The hard part: every city's permit site works differently, so each new portal takes setup time and needs fixing when the city changes its site.

Run a screening step for small marketplaces, plugin stores and directories that take listings from the public. A decision model (a fast AI that only makes yes/no or sorting calls) checks each new listing for scams, phishing, impersonation and offensive content. It then approves the listing or sends it to a person to review. The hard part: convincing small marketplace owners to add a new step to how they accept listings, and tuning the questions so few good listings get held back.

A small tool checks the pricing pages of an online store's competitors and emails the owner a weekly report of what changed. Store owners pay a monthly fee so they no longer have to check by hand. The hard part: keeping the price checker working as each competitor's pages change, and finding store owners willing to pay for it.

Recruiters and small hiring agencies pay for a screening tool. They type in their own hiring criteria, and a decision model (a fast AI that only makes yes/no, sorting or scoring calls) scores each CV from 1 to 5 and quotes the CV line behind each score. The hard part: getting recruiters to trust and switch to a new tool when the hiring software they already use may have screening built in.

Build a simple web tool where a restaurant owner types in this week's menu specials and gets seven days of social media posts back. Owners pay a small monthly subscription. The hard part: getting busy restaurant owners to notice and try the tool when many cheap caption writers already exist.

A playbook for phone apps: ask new users a few questions when they first open the app, show them a plan built just for them, then put a paywall (a screen that asks them to pay before they can go on) right after it, with a featured yearly plan and a free trial. The hard part: designing onboarding questions and a plan that feel truly personal, then getting enough people to download the app in the first place.

Score each new event in one niche routine with a decision model (a fast AI that only makes yes/no or sorting calls), then send subscribers only the act or skip verdicts. The hard part: picking a niche where the signal is clear and users keep trusting an automated score.

Build a simple online tool for independent used-car dealers. It adds up the purchase price, repairs, fees, and sale price of each car to show the real profit. Dealers pay a monthly subscription so they can stop relying on spreadsheets that hide their margins. The hard part: reaching independent dealers, who rarely shop for software online and are used to their spreadsheets.

When a tool that people rely on announces it is closing, build a simple replacement that pulls in the same data and shows the same screens. Then charge the users who are about to lose it. The hard part: spotting the shutdown early and shipping something users trust before they settle on another replacement.

Newsletter writers pay for a tool that lists brands already sponsoring similar newsletters, so they know who to pitch instead of guessing. The hard part: keeping the sponsor list large and current enough that writers find brands they had not already thought to pitch.

Offer a tool that turns a person's written scripts into short videos using their own face and voice. Founders, small online brand owners and people with day jobs who post educational videos pay monthly so they can keep posting. The hard part: making videos that look and sound enough like each customer that they will post them, and finding users one demo call at a time.

Before building a phone app, use an app revenue tracker like Sensor Tower to find categories where apps already earn $50K or more a month. Then build a simpler one-screen, one-feature app for the same paying users and copy how the leaders market. The hard part: finding a short video format and small creators that actually bring installs, then repeating it long after it feels boring.

Build a study app where students upload their own lectures, textbooks and PDFs and get back quizzes, flashcards and an AI voice tutor. Students pay a monthly subscription. The hard part: getting students to find your app among many study tools and keep using it after exams end.

Build a subscription tool that turns a trade contractor's job notes, voice memos or photos into a branded quote in minutes. Clients pick options, sign and pay a deposit online, and the tool follows up on any quote nobody has signed. HVAC, roofing, electrical, plumbing and renovation contractors pay a monthly fee. The hard part: getting busy contractors to change how they already quote while several similar new tools compete for the same trades.

Train a small open AI model on one narrow yes/no judgment, host it, and charge developers who need it at volume for each use. The hard part: finding a niche with enough labeled data and buyers who will pay per call.

Build a tool that watches Reddit, X and Hacker News for posts asking for a recommendation, looking for an alternative to a competitor, or complaining about a problem. It scores each post for how ready the person is to buy and drafts a reply. Software founders pay a subscription to see these people before their competitors do. The hard part: standing out against many similar tools and making the scores good enough that founders keep checking the list.

Build a Shopify app that answers shoppers' support and sales questions with AI. Store owners pay one flat monthly price instead of the per-ticket fees that many help desk apps charge. The hard part: standing out among the many support apps already in the Shopify App Store and getting store owners to try a new one.

Sell your tool to the agencies that run one platform, such as Klaviyo or Shopify, for many brands, instead of selling to each brand. One agency sale can bring in 10 to 30 brand accounts. You find these agencies for free in the platforms' public partner directories. The hard part: building something that clearly saves agency teams hours each week, then winning over agency owners who already have their own way of working.

Build a simple website builder for owners who aren't technical, made for one type of business such as dentists, cleaners, or food trucks, and charge them a monthly subscription. The hard part: reaching owners in one trade, who don't hang out where software founders do, and making templates good enough that they don't hire a designer instead.
