Bring in your chats with ChatGPT, Claude or Gemini, or write down what you are learning. See what you keep asking about, ask it questions, have it read your week back to you, and quiz yourself with flashcards made from your own sentences. Like NotebookLM, except the notes, the search and the voice all run here, on your machine: no account, no upload, no key.
When you want the files, take them: one button, plain Markdown, yours.
Why this exists
Every tool that offers to remember things for you asks first for an account, and then keeps the memory on its own servers. That is a reasonable trade until the day the plan changes, the company is bought, or you want your thinking somewhere else. This page is the opposite arrangement, made small enough to check in a minute: your words stay on your disk, the search runs in this tab, and the export is text.
It is also the honest shape of the real thing. The Mac version is this loop with a larger model, your whole notes folder instead of a few notes, a morning summary written every night, and a bigger AI only when a question genuinely needs it. With your own Claude key it goes when you press Send, or in one nightly batch; without one, it is packed for you to paste. Same files. Same rule about where they live.
Questions people ask
Where do the flashcards, the quiz and the read-aloud overview come from?
From your own sentences. Each card is a sentence from one of your notes with one particular word blanked; the quiz shows a sentence and asks which of four of your notes it came from; the overview reads one sentence per note, in date order, with the note and date beside it. No model writes any of it, so nothing is invented, and the voice is the one your device already has. Testing yourself this way beats rereading for remembering later (Roediger and Karpicke, Psychological Science, 2006).
What does the Curiosity view show?
The topics you keep asking your AIs about, counted from your own questions and chat titles, never from the AI's answers: how many chats name each one, when you started, the questions you asked lately, and one sentence that came back, quoted from the answer you saved. Bring in your ChatGPT, Claude or Gemini export below, or open the sample of two weeks of AI chats to see the shape.
Does anything I write leave my computer?
No. The notes are stored by your browser on your own disk, and the search runs in JavaScript in this tab. Nothing is downloaded to answer, so it works on any phone and keeps working with the wi-fi off once the page is open. There is no account and no server that could receive a note. The one thing that leaves is what you copy yourself, with Copy for my AI, into the AI you choose.
How safe is browser storage?
Safe from other people, but not permanent. Clearing site data, private windows, and some cleanup tools will erase it, and it does not follow you to another browser or device. That is exactly why the download button exists: press it and you have plain Markdown files that are yours regardless of what any browser does.
Why does it show my sentences instead of writing an answer?
Because chanio is the memory, not the AI. Search finds the sentences of yours that answer the question and shows them word for word, instantly, with no model to download. When you want an AI to think with them, Copy for my AI puts the question and those notes on your clipboard, private details blanked out, to paste into Claude, ChatGPT or Gemini, which are far better at thinking than anything that fits in a browser tab.
What do I get when I download?
A zip of Markdown files, one per note, plus a README. Open the folder in Obsidian and it is a vault. On a Mac, drop the notes folder into ~/chanio/notes and the installed version answers from the same files with a larger model.
Is this the whole product?
No, it is the smallest honest version of it. The Mac version answers from your whole notes folder instead of a handful of notes, runs a larger model, writes you a morning summary each night, and keeps a question for tonight when your notes don't settle it. With your own Claude key, the questions kept for tonight go to a bigger AI in one batch, and a meter shows what went. This page is the same loop, small enough to try in ten seconds.
