Jungle is a study app. A student uploads lecture slides, a PDF, notes, a video or a lecture recording, and the app turns it into multiple-choice questions, flashcards and clinical-case questions in the style of exams such as USMLE Step 1, the first United States medical licensing exam. The questions are written by a large language model (LLM), an AI program trained on large amounts of text that writes text from instructions. The app then schedules reviews by spaced repetition, a method that shows a question again just before you are likely to forget it. It runs on the web, iPhone and Android. The company behind it is Mindflow Inc. in California.

Julian Alvarez, a developer who grew up in a Texas border town and had worked at LinkedIn Learning and Meta, built the first version with his co-founder David Glass in one 21-hour coding session in January 2023, in reply to a viral post on X that asked for exactly this tool. It launched on 29 January 2023 under the name Wisdolia. By the end of 2023 it had US$300,000 in ARR, annual recurring revenue: the subscription revenue of a recent month counted for a full year. By the end of 2024 it had US$850,000 in ARR, 650,000 users and a profit, with two co-founders and two engineers plus contractors. In early 2025 the founder told investors on the podcast The Pitch that ARR was approaching US$1 million. Before that the company had raised a pre-seed round, a first small round of venture money, of about US$600,000.

Every revenue figure on this page is a statement by the founder, grade C. The only money confirmed by a second party is the US$150,000 that The Pitch Fund and Jesse Middleton of the venture firm Flybridge disclosed themselves in May 2025, invested as SAFEs, agreements that turn money into shares at a later funding round. In June 2025 the founder said growth had started to plateau and that the 2025 round raised about US$300,000 of the US$2 million he wanted. In July and August 2025 OpenAI and Google added study modes to ChatGPT and Gemini. The page also shows what happened to earlier companies that tried to make studying and quizzing more engaging.

Jungle: US$850K a year in recurring revenue, December 2024. AI study app that makes questions from your own material, United States, team of 2 to 10, evidence grade C.

How to read this table: a grade C value is a statement by the founder or the company, or a third party that repeats it. Grade B is an investor's own disclosure of its investment. A "calc" value was computed on this page from the rows above it. No revenue figure is grade A or B.

The web pricing page names its paid plans Pro and Elite but loads their prices by script, so they could not be read; this table uses the App Store's in-app purchase prices instead, and how the store's plan names match the web plans is not stated. Yearly prices are shown per month (calculated: the yearly price divided by 12). Super Learner is also sold weekly at US$6.99. In early 2025 the founder gave the prices as US$8 a month for the middle plan and US$20 a month for the top plan, and the free plan then allowed 15 generations a month.

03

Why it worked

Four causes, in the order they mattered. Each one is a reusable lesson.

01

Distribution

The product was simple to copy, so the founders put their effort into finding students: first AI directories and the video reviewers who read them, then one niche, then paid creators and ads that paid back. The founder says that in generative AI the main defense is to move fast and experiment more than others: 50 to 100 experiments a month, reviewed every Monday.

02

A fast reply to a public request

On 25 January 2023 a post on X asked for a GPT tool that makes Anki-style flashcards from what you read. The founders built it in one 21-hour session, replied to the post, and messaged every person who engaged with it, which brought the first 100 users. They talked to each of them and changed the product from their feedback.

03

One niche with the most need

Usage data showed that medical students used the app far more than anyone else. They are also the main users of Anki. For about a year all marketing aimed at them, and the product added clinical-case questions in the style of medical exams, which law and dental students then found useful too.

04

Paid student creators

One medical student's TikTok video reached 2.5 million views and lifted monthly revenue from about US$2,000 to US$15,000 within one to two weeks. The company turned this into a program: about 30 students paid to run their own accounts and post about 12 videos a week each, 76 million views in three months.

How it was built

These details come from the founder's statements, the company's own pages and its Google Ads contractor. They are grade C. [2, 11, 12, 8, 13, 10, 7]

  • Prompts on top of large language models, plus "some fine tuned models", in the founder's words in early 2025. He said the prompt had been revised more than a hundred times. No source read for this page names the model provider.
  • Question quality is tested with an LLM as the judge: each platform generated questions from the same 3 documents, and the questions were scored without showing which platform made them. The home page compares Jungle with Quizlet, Turbo, Gizmo and StudyFetch.
  • Google Firebase for the backend database and login, Amplitude and Google Analytics for analytics, and Smashsend for email marketing, per the privacy policy.
  • The website was built on Webflow, and the Google Ads campaigns were measured with Google Analytics 4, per the ads contractor's case study.
  • A web app plus iPhone and Android apps from the developer Mindflow Inc. The iPhone app sells the paid plans as in-app purchases.
  • Features beyond questions: image occlusion (labels hidden on a diagram for the student to name), lecture recordings, an AI voice tutor, spaced repetition, export to Anki, streaks, and a tree that grows as the student answers.
  • An experiment hour every Monday, with 50 to 100 experiments a month on ads, pages, prices, onboarding and features.

The dead that came before

Four companies in the Loot Drop database promised students or parents a better or more engaging way to study or quiz, and failed. The values below are from that database and are not independently verified.

Died 2007 to 2015Burned US$44.4M

Grockit

The promise

Social, game-like test preparation for the SAT and GMAT.

Why it died

Kaplan, a large test-prep company, bought it in 2013 and folded it into its own business, where the product did not survive.

CompetitionLoot Drop entry ↗
Died 2013 to 2020Burned US$27M

QuizUp

The promise

Real-time quiz battles on thousands of topics.

Why it died

It spread fast, but it never found a way to make money, lost players to live-hosted quiz games, and its buyer neglected it.

No Market NeedLoot Drop entry ↗
Died 2010 to 2012Burned US$1.7M

Airy Labs

The promise

Learning games for children, based on cognitive science.

Why it died

Costly content met free-to-download app store prices, and parents could not see the difference from free apps.

Unit EconomicsLoot Drop entry ↗
Died 2013 to 2021Burned US$150M

Xuebajun

The promise

Photograph a homework problem and get an AI solution.

Why it died

It moved from homework help into an expensive live-tutoring marketplace, then a ban by the Chinese government ended its business.

Unit EconomicsLoot Drop entry ↗

What changed

Each of the four sold a better way to study or quiz, and none found revenue that covered its costs. QuizUp spread fast but never made money from its players, Airy Labs could not charge more than free apps, Grockit disappeared inside a test-prep company, and Xuebajun spent its money on tutors before a ban. Jungle sells to the same buyer, a student near an exam, and has the same weak point: students cancel in summer and leave after graduation.

Two things differ. First, the AI writes each new set of questions from the student's own slides, so the company does not pay people to write course content, as Grockit and Airy Labs had to. Second, it charged early, sold yearly plans to 40% of subscribers, and bought ads only while they paid back, so four people reached US$850,000 a year after a pre-seed round of about US$600,000. The new risk is one the predecessors did not face: the AI model makers now offer study features inside their own chat apps.

05

Can one person copy it now?

The method, yes. The early market, no.

A tool that writes study questions from a student's own files was new in January 2023, and Jungle shipped it within days of a public request. Since mid-2025 ChatGPT and Gemini have their own study modes. What can still be copied is the method: one group of users under exam pressure, paid creators from that group, ads that pay back, and many small experiments.

Where it is still open: Exam-heavy groups that general chat apps serve less well: nursing, law, licensing and certification exams, and language tests, with questions in the exact style of each exam.

  1. 1Build the tool that people ask for in public, ship it within days, and reply to the request yourself.
  2. 2Find the user group with the most urgent need in your usage data, and aim all marketing at it.
  3. 3Pay members of that group to post short videos from their own accounts, several a week each.
  4. 4Buy search ads only while the revenue they bring covers the spend, and sell yearly plans.

What to watch

The risks are the mirror image of the causes above.

Self-reported, and three different measures

Every revenue figure is the founder's own statement. The sources use three measures that are easy to mix up: ARR (US$850,000 at the end of 2024), lifetime revenue (US$1 million in total by April 2025) and money received per month (over US$100,000, which includes yearly plans paid in advance). The July 2026 newsletter repeats "$1M ARR" and "$100K a month" without new dates.

Growth stopped in 2025

In June 2025 the founder said growth "started to plateau a little bit", that the seed round raised about US$300,000 of the US$2 million sought, and that the goal was to get back to profitability. A venture firm passed after diligence, saying the product's maturity fitted a pre-seed round. No source gives a revenue figure after April 2025.

Students leave

Paid churn was 12% a month during a semester and about 19% in summer, by the founders' figures. Medical students use the app around exams and stop after graduation, which limits how much each customer pays over time.

The model makers now offer study modes

OpenAI added study mode to ChatGPT on 29 July 2025 for logged-in users on the Free, Plus, Pro and Team plans. Google launched Guided Learning in Gemini on 6 August 2025. Investors on The Pitch said they already upload PDFs to ChatGPT and ask it to quiz them.

Large study apps compete for the same students

Jungle's home page names Quizlet, Turbo, Gizmo and StudyFetch as competitors. Its ads contractor wrote that Quizlet and Anki dominated the same search ads. The founder said many of Jungle's users came from Anki or Quizlet.

School and exam rules on AI

Guidance from England's Department for Education, updated 12 August 2025, says schools may review homework and unsupervised-study policies because of generative AI, and need to keep taking reasonable steps to prevent malpractice involving generative AI in formal assessments. Practice questions made from a student's own slides are revision, not assessed work; the risk is that a school's general rules on AI tools cover them too.

Dependence on model providers

The product is prompts and some fine-tuned models on top of large language models from providers that the sources do not name. The founder said generative AI gives no strong protection against copies, and the host of The Pitch said everybody uses the same models. A price rise or a rule change by the provider affects the margin directly.

A larger team after the headline figure

The headline figure is from the end of 2024, when the team was two co-founders and two engineers. From March 2025 the about page lists 7 people and an advisor, plus about 30 paid student creators, so the 2025 figures come from a team of 7.

User data may be licensed for AI training

The privacy policy read in October 2026 says the company may license or sell data collected through the service, including personal data, to third parties, including for training AI models. Students who upload course material may object.

AI language tutor app · Canada

Verbi

Evidence A
US$250,824still running, revenue falling · 6 months after launch
The product

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.

Why it worked

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.

AI writing add-in for Microsoft Word · Germany

fastwrite.io

Evidence A
US$183,602still running, revenue falling · 17 months after launch
The product

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.

Why it worked

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.

AI study app for students · USA

ChatEDU

US$120,117still running, revenue falling · 22 months after launch
The product

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.

Why it worked

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.

The product

The customer picks a topic, a video style and a posting schedule. The service writes a story, edits it into a short video and posts it to the customer's TikTok, YouTube or Instagram account on that schedule. The customer never appears on camera and does not have to edit anything.

Why it worked

It sold the whole job, from the story to the posting, and not only a video editor. One paid thread by a known account on X brought the first customers, and creators who used the product then recommended it to their own audiences. One founder built everything on a no-code platform that he already knew from six failed products, so the first version was cheap and fast to change.

LinkedIn lead finder for sales teams · USA · Funded

Evidence A
US$645,024still running, revenue growing · 5 months after launch
The product

A LinkedIn lead finder for B2B sales teams. You list LinkedIn profiles to watch; traxy collects the people who like, comment on or repost their posts, scores each one against your ideal buyer, adds an email address and phone number, and an AI agent can write and send the first message.

Why it worked

The founder already ran a LinkedIn ghostwriting agency and built the lead tool that the agency needed. He sold it with the tool itself: traxy found the leads, and his team contacted them. Daily posts on X added trials, and credit-based prices let heavy users pay more.

Live AI voice translation for churches · Cyprus

Glossa.live

Evidence A
US$182,185still running, revenue growing · 16 months after launch
The product

A church connects the audio of its service, from a microphone or the sound desk, to Glossa in a browser and starts a stream. Glossa turns the speech into text, translates the text, and reads the translation aloud with a synthetic voice. Each visitor scans a QR code, picks one of more than 100 languages on a phone, and listens with earphones or reads the captions. The church needs no receivers and no interpreter booth. It pays for the minutes of speech in each language, not for the number of listeners.

Why it worked

Churches with members from many countries meet every week, and the older solutions cost too much for most of them: an interpreter for each language, or radio receivers to hand out and collect. Glossa charges US$5 for one hour of speech in one language, counts by the minute, and charges nothing for silence, songs or extra listeners, so a small church can start with four free hours and then a few dollars a week. The product is shaped for this one buyer: captions go into ProPresenter and OBS, which churches already run, and a church can fix how names, Bible quotations and its own terms are translated. A very small team can offer this because the speech recognition and the voices are rented from model companies and paid by use.
