Finally understand the AI everyone's talking about. Tokens, prompts, RAG, agents, in plain English, then try every concept hands-on, right on your phone.
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 iPhone
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 iPhone.

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.
This release makes Latent more personal, more social, and easier to keep coming back to.
