lrnit
For developers

Learn AI agent engineering in a course built only for you. And actually retain it.

Move past chat wrappers. Learn the architecture of real AI agents: tool calling, orchestration loops, memory, evals, and the failure modes that kill agent products.

What your course could open with

lrnit interviews you first (what you know, why you’re learning, how you think), then generates every lesson for that. Sample lessons from a course like yours:

  1. 01The agent loop: model, tools, and state, and what actually happens per turn
  2. 02Tool design: schemas the model can’t misuse
  3. 03When agents lie: grounding, verification, and structured outputs
  4. 04Evals before scale: measuring agent quality like an engineer
  5. …and the rest is generated for you: your gaps, your pace, your job.
Measured, not watched

By the end, you’ll be able to

What a capability check looks likebeforenow
Design a tool schema+62
Ground and verify outputs+63
Stand up an eval harness+65

Every lesson ends in assessment. Mastery is tracked per concept with spaced review, and the course adapts to what you actually retain. Finishing means a timed final exam and a verifiable certificate, not a completion badge.

Questions people ask

What should I already know?
Working programming experience and comfort calling an API. You do not need a machine-learning background; the model side you need is covered.
Does this go past building a chat wrapper?
Yes. It covers the agent loop, tool design, grounding and verification, and the evals that keep an agent honest at scale, which is where most agent products break.
Is it tied to one framework?
No. It teaches the architecture and failure modes, so the patterns transfer whether you use LangChain, a vendor SDK, or your own loop.
