The tutor is an AI model, so the company pays for computing and has no teacher to pay by the hour. That allows a yearly price of US$47.99 to US$79.99. Customers came from a very large number of short videos on TikTok and Instagram: first slideshows that the founder's own tool generated and that two people posted from about 12 accounts, then videos by paid creators. Yearly plans are paid in full on the first day, so the cash arrived early. Half of all revenue came in September 2026, and daily sales have fallen since.

Seven years of research at a Norwegian university produced the method, the training data and the avatar before the company existed. The founder is the professor who led that research, the university licensed the technology to her company, and public bodies that must train staff in child interviews are the customers. The filed accounts show revenue of NOK 816,000 in 2024 and NOK 2,176,042 in 2025, at a loss.

It launched in July 2023, when the ChatGPT plugins for PDF stopped at about 300 pages and Myreader took a whole library. It sold a cheap subscription limited by pages and questions, and it got its users from Google: the TrustMRR profile says the business has good SEO and about 30 sign-ups a day, and the site has a page for each kind of reader, from medical students to seminary students, and a free page for each of more than 40 public-domain classics.

It sells a weekly subscription for a task students repeat before every test, and it charges from the first screen: the App Store reviews complain that the app cannot be used without paying. One small studio ships the same shell, the same legal pages and the same billing stack across six apps, so each new app costs little. The revenue, read from the app's RevenueCat account, reached US$23,480 in its best month and US$174,534 in total within twelve months of launch.

It starts from the student's own course files instead of general knowledge, so answers and practice questions point back to the material that the class uses. A free plan with monthly limits lets students try it, and Pro is sold by the week or by the month. Stripe shows about US$13,200 a month at the end of 2025; the seller says growth came with little to no marketing, and no source explains how students found it.

Speaking is the part of a language that learners practice least, because a human partner is expensive or not available. An AI tutor that listens and answers by voice is available at any hour for a fixed subscription. The founder chose search as the way to find learners: the website has about 1,600 pages in ten languages, and TrustMRR, reading the site's Google Search Console account, counted 460,920 Google search impressions in 30 days.

Choosing a lure is the question that every new angler has at the water, and a phone camera plus weather data can answer it in seconds. One developer built a narrow app around that single question, put the answer behind a subscription, and promoted it with short videos on TikTok. Sales are highest in the summer fishing months.

System design interviews are hard to practise alone, because the value is in the follow-up questions that a senior engineer asks about your design. A language model that can read the diagram and the chat can ask those questions at any hour. The free plan gives unlimited practice, and the Pro plan at US$14 a month sells the analysis, the score and company-specific questions.

Questgen started as free open-source code on GitHub whose README sends readers to questgen.ai, where the paid plans are. Both apps then won search traffic for exact phrases such as "AI meme generator", and Supermeme says it has spent nothing to acquire its users. Costs are low: in June 2022 the founder said his two products were profitable at US$500 and US$100 a month. So a part-time team with no investors can keep them running.

It serves one narrow group of buyers, people who publish low-content paperbacks on Amazon KDP, and does every step they otherwise do with four to seven separate tools. Revenue stayed at a few hundred US dollars a month for a year, then grew after the founder replaced the free tier with a card-gated trial long enough to finish a whole book.

He solved a problem he had paid for himself and shipped the simplest version in about two weeks. Then he wrote useful Reddit posts with the product link in the middle and posted each one in many related subreddits. With 70 to 115 followers on X, he says this brought over 1 million views and about 20,000 signups by July 2025.

Founders and small B2B teams know their subject but do not have time to write for every social network, and generic AI writing does not sound like them. CaptureFlow starts from material the person already produces, a call, a voice note, a recorded talk, and reshapes it into native posts in their voice. TrustMRR, reading the company's Stripe account, shows US$4,182 of monthly recurring revenue from 9 subscriptions and US$28,071 of revenue in total on 27 October 2026, with monthly revenue growing every month of 2026.

It took a narrower job than the general AI design tools, mobile apps only, for people who build apps without design skills. The three founders reused what they had learned from four earlier design tools, built it in three weeks, and showed finished designs on X before the launch. Each new Gemini model gave them a better result and a new demo to post.
