Where your text goes.
Runs entirely in your browser
PDF to text, the word counter, the readability checker and the document diff process everything on your own device. Your file or text is never uploaded - to us or anyone else.
Calls the Sidenote API
The AI summarizer and reading level rewriter send your text to our servers to run the AI and return the result - nothing is kept afterwards beyond an anonymized rate-limit count. The citation generator sends only the DOI, arXiv ID or URL you're looking up - never a document.
Stop digging. Start asking.
Add Sidenote to your browser, open any page in your wiki, and ask it the question you’ve been Slacking the team about.
