Wake up with more than
you went to bed with.
You already think out loud to AI all day. Paste in what matters and chanio keeps it as plain notes on your Mac, where the small AI works through the day's notes overnight. By morning, a summary of your own thinking is waiting. Same loop, every night.
Capture
The chats you have with Claude, ChatGPT, and Gemini all day — the questions, the corrections, the half-formed ideas. The richest record of how you think already exists. Paste the ones that matter into chanio and it keeps them.
Store
It lands in your notes folder on your Mac; open it in Obsidian if you like. Plain Markdown you can read, search, and own forever. Not a cloud you rent — a library you keep.
Compound
Two passes while you sleep. First the small AI on your Mac reads the day's notes and saved pastes and writes the morning summary, on your Mac: what mattered, the threads still open, the questions worth asking, and where your notes disagree. Then the questions you kept go out in one batch: to Claude on your own key, under a daily spending limit you set, or packed for you to paste into any AI you use. Only if you kept any. Not autonomous agents inventing work; a summary of what you already made.
Revisit
You wake to a morning summary — not a transcript. What mattered, the threads still open, the questions worth asking, and answers to what you kept. You read it, you question it, you stay in the driver's seat. The loop runs again tonight.
The model is rented. The mind is yours.
Built for one thing: thinking that compounds.
Most of your best thinking evaporates. The loop exists to stop that, and for nothing else.
Every claim, with its limit attached.
We'd rather you trust this than be wowed by it. Here's what the research supports — and exactly where it stops. Every card links to the source.
Your notebook can be part of your mind. Literally.
Clark & Chalmers' "extended mind" argued that a reliable external store you use fluently is a genuine part of your cognition. Their original example was Otto — a man with Alzheimer's whose notebook did the remembering. chanio is Otto's notebook, for your thinking.
Honest limit: the "Google effect" — when you know something is stored, you encode it less. The fix is synthesis, not archive: chanio pushes processed understanding back to you, so you engage with it, not just file it.
Your brain consolidates memory while you sleep. So can this.
During deep sleep, the hippocampus replays the day and hands it to the neocortex for durable storage — and connects it to what you already knew. chanio's overnight job is a parallel process: it works the day's material in a quiet window and returns it integrated.
Honest limit: it's a parallel, not the same mechanism. Sleep rewires neurons; chanio rewrites a document. The integration still happens when you read the summary in the morning — which is the point.
Spaced revisiting is one of the most proven ways to learn.
Retrieval practice and spaced repetition are among the most replicated findings in cognitive science: coming back to material at intervals, and pulling it from memory instead of re-reading it, reliably beats cramming for durable retention. The morning summary is spaced retrieval without flashcards.
Honest limit: this compounds what you've actually worked on — it does not raise fluid IQ. Working-memory "brain training" famously fails to transfer. chanio makes your real knowledge durable; it doesn't hand you a higher g-factor.
AI augments you — only if you stay active.
A Science RCT found generative AI cut professional writing time 40% and raised quality 18%. But an MIT study found people who passively outsourced to AI showed weaker neural engagement and couldn't recall what they'd just "written" — "cognitive debt."
The whole design hinges on this: passive outsourcing atrophies thinking; active interrogation augments it. chanio gives you a summary to read, question, and annotate — never an answer to rubber-stamp. Driver's seat, not passenger.
