Building with Agentic AI
Move beyond simple chat and learn how to build AI systems that can use tools, plan complex tasks, and work autonomously to solve real-world problems.
Like Duolingo, but for Building with Agentic AI. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
20 levels across 4 sections, about 40 minutes end to end, roughly 8 days at five minutes a day. It moves through From Chatting to Doing, Managing Complex Workflows, Reliability and Control, and The Mechanics of Agency. It starts from scratch.

Key ideas in Building with Agentic AI
- Standard AI provides information based on a prompt
- Agentic AI takes responsibility for a multi-step outcome
- Agents can interact with external tools to finalize a result
- The agent first reasons about what to do next (Thought)
- The agent executes a command or uses a tool (Action)
- The agent looks at the result of that action to decide the next step (Observation)
- The fundamental shift from answering questions to achieving goals
- The 'Thought-Action-Observation' loop that drives agent behavior
- Simple automation follows a fixed path
- Autonomy is needed when the path changes
- Agents excel at fuzzy tasks
- The 'Thought-Action-Observation' loop
- A persona acts as a filter
- Identifying tasks that benefit from autonomy versus simple automation
- AI models are naturally 'text-in, text-out' and cannot touch other apps directly
- Tools act as the digital hands that allow an agent to execute commands in the real world
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Building with Agentic AI the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
