The revenue trend compares the latest months in the sources with the months before them. Falling means revenue is about 15% or more below the best recent months, or the sources report a fall. The headline number is the yearly figure or the sale value on each card.

A phone app for practicing a foreign language by speaking. The learner talks out loud with an AI tutor in short voice lessons and free role plays, and gets feedback after each attempt. Around that sit a daily word feed, quizzes, verb drills, listening clips and a progress score. Nine languages. The download is free and the lessons need a subscription, listed in the US App Store at US$7.99 or US$8.99 a week or US$29.99 to US$79.99 a year.
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.
An add-in for Microsoft Word, plus a web app, for German-speaking students who write seminar papers and theses. The student uploads the PDFs of the literature. While the student writes, fastwrite suggests the next sentence or a whole paragraph with a citation from those PDFs, and the Tab key accepts it. It also answers questions across all uploaded PDFs with the exact page, searches more than 20 million papers, and checks a draft against nine criteria that universities use for grading.
It puts the AI where German students already write, inside Word and in German, and each suggestion carries a citation from the student's own PDFs, so the student does not have to fear invented sources. A free plan without a time limit brings students in, and a monthly plan sold for the months in which they write turns some of them into paying customers.
An AI study app. A student uploads class materials, such as PDFs, lecture slides, notes, images or YouTube videos, and gets answers with citations to those files, practice questions, flashcards, study guides, audio summaries and a topic-by-topic progress view. It runs on the web and, since May 2026, as an iOS app.
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.
A phone and web app that records a lecture, or imports audio, video, a PDF, a document or a link, and makes a transcript, organized notes, flashcards, quizzes, a chat with the note and a short AI-narrated podcast of it. A student gets one free note; after that the app needs a subscription, which starts with a free trial.
Two former Loom staff built a premium-priced app for something students do several times a week, going to class, and sold it through short videos by a small group of contracted creators instead of paid ads. It charged from the first day, and revenue paid for growth with about 50% EBITDA margins until Quizlet bought it.
A phone app for practicing a foreign language by speaking. The learner talks out loud with an AI tutor in everyday scenes and role plays, gets corrections on pronunciation and grammar during the conversation, and the app keeps a learning plan and remembers past mistakes. More than 25 languages. A free trial, then a subscription through the app stores.
Speaking is the part of language learning that most apps practice least, and the founders built the practice partner that they had been for each other. A short video format, in which the AI points out a creator's pronunciation errors, spread on TikTok through about 100 creators that the company manages, with no paid ads by the co-founder's account, and a simple subscription turned a small part of the free users into payers.
A text editor for students and researchers in which a language model suggests the next sentence, writes from the PDFs you upload, and inserts citations in more than 1,700 styles. Free with a daily word limit; paid plans remove the limits.
After three years stuck at US$2,000 a month as a marketing-copy tool, it narrowed to one group, students writing papers, and sold to them through short videos on TikTok and Instagram made by many small creators. One viral post in July 2022 gave it the first thousand customers; a system of paid creators and referral programs kept the growth going.
A study app that turns a student's own lecture slides, PDFs, notes, videos and lecture recordings into multiple-choice questions, flashcards and exam-style clinical-case questions, gives feedback on each answer, and schedules reviews so that weak topics come back. It runs on the web, iPhone and Android, with a free plan and paid plans.
It shipped within days in reply to a public request for exactly this tool, in January 2023, when AI tools were new and AI directories and their video reviewers sent traffic at almost no cost. It then aimed all marketing at medical students, the heaviest flashcard users, paid student creators to post about it on TikTok and Instagram, and bought Google Ads only while they paid back their cost.
Three small AI web apps from one founder, run beside his full-time job. Questgen turns text, PDFs, web pages, images or videos into quizzes (multiple choice, true/false, fill in the blank) and exports them in the file formats that school learning systems import. Supermeme.ai, built with two co-founders, turns a sentence into memes: it finds fitting meme templates and writes the captions. AiArtist.io, the newest, makes short motion-graphics videos from text.
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.
The next verified one-person AI business goes here. Same structure, same evidence grades.
