Tomo is a small product with a clear idea: take a topic you are curious about, and turn it into a five-minute game instead of a wall of text. It ships as an iPhone and Android app, but the interesting part is the ChatGPT plugin - ask for a course in a conversation and the game appears in the chat.

The maker is Mohannad Ali, who describes himself as the solo maker. The listing calls it “a learning app that turns any topic into a short course you play like Duolingo, with hearts, streaks, XP and instant feedback.”
What it actually does
From the launch description and the maker’s own comment:
- Any topic. Not just languages: black holes, sourdough, the fall of Rome. The AI builds the course in minutes.
- Duolingo mechanics. Hearts, streaks, XP, instant feedback, a score at the end.
- Teacher personas. You pick who teaches it - The Bestie, The Professor, Explain like I’m 5, The Storyteller, or The Pirate. Same facts, different delivery.
- Two entry points. The standalone app, and the ChatGPT plugin.
- Conversation to course. Deep in a thread already? Say “turn this chat into a Tomo course” and play what you were just discussing.
The maker frames the problem in a way that will be familiar to anyone who uses ChatGPT daily: “You ask ChatGPT something, get a great answer, nod along, and close the tab. Tomo gives that curiosity somewhere to go.”
That is a real gap. Chat is excellent at answering and terrible at retention.
The plugin is the distribution story again
This is the third product in a week to show up in this feed with the same shape: a working app, plus a ChatGPT plugin that puts it where the conversation already is. Earlier it was Stack Overflow for Agents, where OpenAI reported the plugin helped drive growth in agent creation.
The pattern is consistent enough to name. A plugin is not a marketing channel; it is a zero-step install. The user does not open a site, create an account, or copy a link. They ask, and the thing appears.
Tomo’s implementation is a good example of doing it natively rather than bolting on: the course is generated from the conversation’s context, which is the one thing a standalone app cannot do.
The best design detail is about trust
One line in the maker’s comment deserves to be copied by anyone building an AI product with a quiz or an assessment in it:
“ChatGPT never even sees the answers, so it can’t spoil them.”
That is a small architectural decision with a large behavioural effect. If the model generating the questions also holds the answer key in its context, then any follow-up prompt can leak it - “just tell me the answers” is a legitimate request to a helpful assistant. By keeping the answer key outside the model’s context, Tomo makes cheating require actually playing.
The general principle: do not give a model access to data it does not need for the current step. It applies far beyond quizzes - to held-out test sets, to grading rubrics, to pricing rules you do not want the agent to negotiate against itself.
What gamification buys, and what it costs
Hearts and streaks are engagement mechanics, and they work - Duolingo built a business on them. But they optimise for a specific thing: returning tomorrow. That is not the same as learning.
- Streaks reward showing up, which is good for habit and neutral for understanding.
- Hearts punish errors, which can push users toward easier material - the opposite of desirable difficulty.
- XP rewards volume, which is easy to game by replaying what you know.
None of that makes Tomo bad; a five-minute daily habit is a reasonable goal for curiosity. It does mean the product should be judged on whether you can still explain the thing a week later, not on the streak count.
The honest caveats
- Accuracy. An AI-generated course on sourdough or Roman history is only as good as the model’s facts, and a wrong fact taught with a streak attached is stickier than a wrong answer in chat.
- Plugin dependency. The ChatGPT integration lives on someone else’s platform, with someone else’s plugin policy. The standalone app is the hedge, and it is wise that they have one.
- Solo maker. One person can ship fast and also disappear; the app’s durability is a real consideration for anything you would build a habit on.
- Persona theatre. Teacher voices are fun, and they are also a place where style can outrun substance.
What desktop agent builders can take
Three transferable ideas, none of which require a plugin:
- Turn output into a loop. A document is a dead end; a question with instant feedback is a loop. If your agent produces a summary, consider producing a check instead.
- Keep the answer key out of context. Whatever your agent grades, verifies or scores, hold the reference outside the model’s window.
- Meet the user inside the tool they already have open. For Tomo it is ChatGPT; for a Windows agent it is the file explorer, the tray, the app you are already in.
MOOGH takes the third point literally - it works on the files and apps already open on your Windows desktop instead of asking you to move your work somewhere else: [download MOOGH].
FAQ
Is Tomo free? The listing says free to start, with no sign-up to begin. Paid tiers, if any, are not described in the material summarised here.
Does it work without ChatGPT? Yes - it is an iPhone and Android app first, with the plugin as an additional surface.
Is it only for languages? No. The examples given are black holes, sourdough and Roman history, and the course is generated from whatever topic you ask for.
Can I use it for work training? You could generate a course on anything, but the accuracy caveat matters more for compliance or safety material than for curiosity.
