Free tools
Useful on their own. Nothing leaves your machine.
Each of these does one job, in your browser or on your own Mac, with no account and no upload. They are also how chanio thinks: files you keep, models you rent, a meter you can read.
in your browser
A notebook that answers
Write or paste notes, then ask them questions. The notes, the search and the model all run in the tab; download everything as Markdown whenever you like.
in your browser
ChatGPT export → Markdown
Drop the ZIP OpenAI emailed you; get one Markdown file per conversation plus wikilinked topic pages. Nothing uploaded.
in your browser
Claude export → Obsidian vault
The same converter for Claude's data export. Opens as a vault; lights up the graph view.
in your browser
AI cost calculator
What a month of your questions costs at API list prices, versus on-device at $0 with one nightly frontier batch.
in your browser
Which local model fits your Mac?
Pick by memory: the safe default, the bigger brain that fits, and the one command to switch.
in your browser
Export rescue
The full version: graph preview, topic map, a structured sample capture, and the vault download.
in your browser
Try a model in your browser
A real small model downloads into the tab and answers from what you teach it. Turn off wi-fi; it still works.
on your Mac
The chanio starter
One line on a Mac: a local model, a Markdown notes folder, ask/hold/capture/nightly/brief/meter.
