Learn AI the hands-on way. A lab with 23 on-device exercises — streaming, RAG, tool-calling, vision, and live speech. All private, all on your device.
Latent makes AI make sense.
Everyone's talking about AI — tokens, prompts, embeddings, RAG, agents, hallucination. Latent is the calm, structured way to actually understand all of it, then try it with your own hands.
It's built for curious professionals, founders, product and engineering managers, and anyone who wants to go from "I've heard the term" to "I get it — and I can use it."
WHAT'S INSIDE
• 18 chapters and 100+ bite-size lessons — a clear path from "what's a token" to building with AI
• Plain-English explanations, real analogies, and quick quizzes that make ideas stick
• A hands-on Lab with 23 interactive exercises that run real AI on your device
THE LAB (this is the fun part)
Don't just read about AI — try it:
• Prompt Playground — tweak a prompt and watch the answer change
• Tokenizer & Temperature — see how models read text and choose words
• Streaming & Structured Output — watch generation happen token by token
• Semantic Search (mini-RAG) — find facts by meaning, not keywords
• Vision Lab — classify a photo and read its text, on device
• Tool-Calling & Grounding — see how AI takes actions and stays honest
• Image Generation & Live Speech — create images and transcribe your voice
PRIVATE BY DESIGN
Latent runs on Apple's on-device AI. No account. No sign-in. Your prompts, photos, and voice never leave your device.

Latent has been one of the best free resources I’ve found for learning AI in a structured, hands-on way. Instead of just reading theory, the interactive labs helped me visualize and truly understand concepts that can otherwise feel overwhelming.The learning path kept me motivated to continue progressing, and I appreciated how it covers practical topics like prompting, evaluations, AI safety, orchestration, and model harnesses, all in an organized, beginner-friendly format.Whether you’re just getting started with AI or looking to upskill, I highly recommend this app. It’s an incredible free resource that makes learning modern AI both engaging and approachable.
Awesome app

I personally find AI hard to learn. This app really makes it easy- it has intuitive lessons with quizzes after each section to make sure you retain the info and it also has different ways to study. Very helpful app!

Really great app for learning AI in a simple, hands-on way. The lessons are easy to follow, the quizzes help everything stick, and the labs make tricky concepts feel much less intimidating. Super helpful and fun to use!

I am really happy I found this happen. It really leveled up my knowledge to a point where I feel confident holding my own in a technical conversation.
Concepts you can see, and a glossary you'll want to browse.
• Concept diagrams bring key ideas to life with clean visuals across lessons, the glossary, and quizzes.
• The redesigned glossary is a clear A to Z dictionary for looking up any term in plain language.
• A smoother first run, including a hands-on "Try it" moment that shows AI working on your device.
