Introducing KnowledgeMonkey — your AI-native second brain
Today we're opening up KnowledgeMonkey to the world. Here's why we built it, what it does, and how to take it for a swing.
Web · iOS · Android · Free to start
Your second brain,
built for AI.
Capture. Organize. Talk to it. Talk hands-free, switch between GPT, Claude or Perplexity, and turn scattered chats into notes, courses, books and study material you actually keep.
Built for AI from the ground up: Give structure to the conversations you have with AI.
Features
Everything an AI-native brain needs
Capture by voice. Organize visually. Search semantically. Take it everywhere — and own every byte.
Talk to it, hands-free
Drive, walk, cook — capture ideas and have full back-and-forth conversations with your knowledge base, no keyboard required.
Choose your LLM
Plug into GPT, Claude, Perplexity and many more. Pick the right model for the job — or bring your own API key.
AI-searchable knowledge chunks
Your knowledge is broken into semantic chunks. No matter how big it gets, the AI always finds the right bits.
Tree, mind map, or list
Reorganize the same knowledge as a tree, a mind map, or a simple list — whichever way your brain prefers.
Use it from inside ChatGPT
Already living in ChatGPT? Hook KnowledgeMonkey in and let it remember everything for you across sessions.
No data lock-in, ever
Export your entire brain as Markdown, plain text or CSV any time. It is your knowledge — we just give it a great home.
The problem
AI conversations vanish. Your knowledge shouldn't.
We give structure to your AI conversations.
Stop losing the best parts of every chat.You ask, you learn, you forget
Brilliant chats with AI scroll off the screen. A week later you cannot find that genius answer about your business idea.
No structure, no recall
Linear chat threads were never designed to be a knowledge base. There is no shape, no index, no map.
KnowledgeMonkey solidifies it
Every insight becomes a chunk. Chunks become trees, maps and projects. Your AI conversations finally compound.
Use cases
What people build with KnowledgeMonkey
Four flagship use cases — and a thousand more your monkey brain will invent.
Capture & organize notes from AI
Every great answer becomes a saved chunk. Tag it, link it, drop it into a project — your AI chats finally stay put.
Build your own training courses
Spin up a course like "Nutrition 101" — one hour, ten short lessons. Listen while you walk, chat at the end of each chapter, edit on the fly.
Study for exams
Drop your notes in, let the AI quiz you, generate flashcards, and explain the bits you got wrong — all in one place.
Write a book on the go
Dictate a chapter on a walk, restructure it into a tree, let the AI tighten the prose, export to Markdown when you ship.
Draft blog posts
Capture the spark in voice, expand it with AI, slot it into your content tree, publish to your favourite platform.
Package & share knowledge projects
Bundle a topic into a shareable project. Let others read it, remix it, contribute back — or keep it private. Up to you.
From idea to organized knowledge — in four steps.
Step 1: Capture
Tap, type or talk. Drop in a YouTube link, a paste from ChatGPT, a voice memo. Anything becomes a knowledge chunk.
Step 2: Organize
Flip between tree, mind map and list. Drag chunks into projects. Let the AI suggest the structure for you.
Step 3: Talk to it
Hands-free chats with your own brain. Quiz yourself, draft a chapter, listen to a lesson — pick your favourite LLM.
Ship & share
AI-native, end to end
Not bolted-on AI. Born with it.
Multi-model by design
Switch between GPT, Claude, Perplexity and others per project — or per question. The right brain for the right job.
Semantic everything
Every chunk is embedded and indexed. Search by meaning, not keywords. Scale to thousands of notes without losing the thread.
Voice as a first-class input
Hands-free conversations are not a feature. They are how the product was designed from day one.
Generate, edit, restructure with AI
Let AI rewrite a lesson, condense a chapter, or turn a tree into a mind map — all from inside the app.
From the troops

Build your own one-hour training course in ten minutes
A walkthrough of using KnowledgeMonkey to spin up "Nutrition 101" — ten short lessons you can listen to on a walk, with an AI conversation at the end of each chapter.
The right LLM for the right job — why one-model thinking is over
GPT, Claude, Perplexity, Gemini — they're not interchangeable. Here's how to pick the right brain for the right project inside KnowledgeMonkey.
The end of lost AI conversations
Why the linear chat thread is the wrong shape for the smartest things you say to an LLM — and what we're building instead.
