Start from zero, on the phone you already carry.
Agent tutorials usually assume a laptop, a terminal, and an hour. This one assumes five minutes and a screen you can hold in one hand — theory, then practice, then a question you can actually ask.
What it is
Learn AI Agents is a free iOS and Android app for learning how AI agents work, starting from zero. It contains more than 100 bite-sized lessons of five to ten minutes each, a real code editor that lets you write and run code on the phone, quizzes and coding challenges after every topic, and an AI Mentor you can ask when a concept or an error stops you. The app is available in 22 languages.
Background
What is an AI agent?
An AI agent is a program that uses a language model to decide what to do next, not just what to say. Instead of returning one answer, it works toward a goal in a loop: it reads the situation, picks an action, calls a tool such as a search index, a database, or an API, reads the result, and repeats until the goal is met or it gives up.
LLMlarge language model
The model that produces the text behind an agent's reasoning and its choice of action. On its own it only predicts text; the surrounding code turns those predictions into steps that actually happen.
Tool callingfunction calling
The mechanism that lets a model ask for a real action — run a query, fetch a page, send a request — by emitting a structured call your code executes and hands back as a result.
RAGretrieval-augmented generation
Fetching relevant documents at question time and passing them to the model as context, so answers rest on your own data rather than on whatever the model happened to memorise during training.
Agent loopplan, act, observe
The repeating cycle at the centre of every agent: decide on a next step, carry it out, look at what came back, and use that observation to decide the step after it.
How it works
How a session actually goes
The app is built for the five or ten minutes you have on a commute or in a queue, so each round is short enough to finish and specific enough to be worth finishing.
Read one short lesson
Pick up where you left off in a lesson that runs five to ten minutes. Each one mixes a small piece of theory with something to do, and every concept is explained in plain language rather than assuming prior experience.
Write and run the code
Move into the built-in code editor and write the example yourself, on the phone, then run it. Quizzes and coding challenges come after every topic, so what you just read gets tested before you move on.
Ask when you get stuck
When a concept will not click or an error makes no sense, ask the AI Mentor and get a clear answer in seconds. Streaks, progress tracking and reminders handle the part where you forget to come back tomorrow.
What’s inside
What comes with the app
100+
Bite-sized lessons
Each lesson runs five to ten minutes and covers one idea — fundamentals first, then the building blocks used in real work, then advanced topics.
AI
AI Mentor
Ask anything, from a concept that will not click to an error message you cannot read, and get a clear answer back in seconds.
</>
Real code editor
Write and run code on the phone itself. No laptop, no local setup, no waiting until you are back at a desk to try the example.
Quiz
Quizzes and challenges
Every topic ends with quizzes and coding challenges, plus hands-on exercises, so the material gets used rather than only read.
Wkly
Weekly Code Challenge
A challenge each week you can take on alongside learners around the world — a reason to open the app on the days motivation is thin.
Exam
Certificate of completion
Pass the final exam and earn a certificate of completion, which is something concrete to point at when the skill goes on a resume.

Fit
Who it’s for — and who it isn’t
A good fit if you
- Are starting AI agents from zero and want plain language rather than jargon
- Learn in five or ten minute pieces on a commute, not in hour-long blocks
- Want to write and run code on your phone instead of waiting for a laptop
- Are a student wanting extra practice alongside classes, or a career switcher building job-ready skills
- Want someone to ask when a concept or an error stops you cold
Not the right tool if you
- Want the full library for free — the first course is free, and Pro unlocks every course
- Do not want ads; the free tier shows them and Pro removes them
- Need unlimited AI help on the free tier, which has a daily AI Mentor allowance
- Are already shipping agents in production and want advanced research material rather than a beginner course
Questions
Frequently asked questions
What is the best app to learn AI agents on a phone?
The one that fits the time you actually have. A good phone course keeps lessons to a few minutes, lets you run code without a laptop, and gives you a way to ask when you are stuck, because that is where most beginners quit. Learn AI Agents is built that way: 100+ lessons of five to ten minutes, a real code editor on the phone, quizzes after every topic, and an AI Mentor for the moments a concept will not click. It is free to start on iOS and Android.
What is an AI agent, in plain terms?
An AI agent is a program that uses a language model to decide what to do next, rather than only what to say. It works toward a goal in a loop: it looks at the situation, picks an action, calls a tool such as a search index, a database or an API, reads the result, and repeats. The model supplies the judgement; the surrounding code supplies the hands.
How is an AI agent different from a chatbot?
A chatbot takes a message and returns a reply — one turn, text in and text out. An agent is given a goal and keeps going until it reaches it, taking actions in the world along the way: querying data, calling APIs, checking its own output, and trying a different route when a step fails. The visible difference is that a chatbot tells you what to do and an agent does it.
Do I need to know how to code before learning AI agents?
It helps, but it is not a prerequisite for starting. Learn AI Agents is written for complete beginners: every concept is explained in plain language and the course starts from zero rather than assuming prior experience. Lessons pair a short piece of theory with hands-on practice, so the coding is learned in the same place as the ideas rather than being a separate thing to go and study first.
Are AI agents worth learning in 2026?
Agents are one of the clearer places where language models turn into something that does work rather than describes it, and the underlying skills transfer widely — prompting, tool calling, retrieval, and reasoning about when an automated system should stop and ask a human. It is an in-demand skill and a strong addition to a resume, and the foundations stay useful even as individual frameworks come and go.
Is Learn AI Agents free?
It is free to start. The first course is free and comes with a daily AI Mentor allowance, so you can work through real lessons without paying anything. Pro is the optional upgrade: it unlocks every course, removes ads and gives you unlimited AI Mentor. The app itself is a free download on both the App Store and Google Play.
Can I really learn to write code on a phone?
For short, focused practice, yes. Learn AI Agents includes a real code editor, so you write and run code on the phone rather than reading about it and trying later. Lessons are five to ten minutes and each topic ends with quizzes and coding challenges, which is a format that suits a phone far better than a two-hour tutorial does.
Does it work when my connection is bad?
It is built for that. Lessons load fast and keep working on flaky connections, which is the normal state of things on a train, on a bus or in a lift. That covers the learning itself; the AI Mentor answers your questions in seconds when you have a connection to ask over.
Do I get a certificate, and is there anything competitive?
Yes to both. Pass the final exam and you earn a certificate of completion, which gives you something concrete to show for the work. There is also a Weekly Code Challenge you can enter against learners around the world, and streaks, progress tracking and smart reminders in between to keep the habit going on the days you would otherwise skip.
What platforms and languages does it support?
Learn AI Agents runs on iPhone and Android and is available in 22 languages. It is rated 4+ and free to download from the App Store and Google Play. It is part of CoddyKit, a family of 40+ coding apps used by more than 100,000 learners worldwide, so the lesson format is shared with the other courses in the range.
