lrnitFor engineers

Learn RAG systems in a course built only for you — and actually retain it.

Learn why most RAG demos fall apart in production — and how to build retrieval pipelines with real chunking strategy, hybrid search, and measurable answer quality.

Built around your goal — not a catalog

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:

01Embeddings as geometry: why similar means close
02Chunking is product design: fixed windows vs. semantic splits
03Hybrid retrieval: when keyword search beats your vector database
04Measuring RAG: groundedness, recall, and the eval set you must build first
…and the rest is generated for you: your gaps, your pace, your job.

Measured, not watched

By the end, you’ll be able to

Diagnose why a RAG system retrieves the wrong context
Choose chunking and indexing strategies from evidence, not vibes
Ship retrieval quality metrics alongside the feature

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.
