Polar has a similar feature if you're just wanting an archive of web pages:<p><a href="https://getpolarized.io/" rel="nofollow">https://getpolarized.io/</a><p>We support 'captured' HTML pages. Basically what we do is we fetch the full HTML of the content and store it in a PHZ file (polar HTML archive) and then we save that to disk (it's just a zip file with JSON metadata).<p>The Polar app is an Electron app so it has full access to render HTML.<p>We then inject our self into the network layer using protocol interceptors and if you're loading the URL you just captured we load the content from the PHZ instead of the network.<p>You can then annotate the content, take notes on it, tag it, and keep it forever without risk of it vanishing.<p>I use it for important documents that I can't afford to ever lose. For example, the Etherium whitepapers are in HTML , not PDF. they're also living documents so I can just capture anytime I want.<p>HTML files don't often print properly so this way I can keep them the way they were meant to be seen.
