Product summary

Review the store description, core capabilities, and common use cases.

You read that thing on that website a few days ago, and you've closed your tab. Now you can't seem to find it again. Whether it's a research article on the latest AI development, or a cooking recipe you were browsing, Casper helps you search all the sites you've visited in the past, and it's all in your browser! Nothing leaves your device.

How does it work?

Casper is your friendly neighbourhood extension, grabbing the contents of the sites you visit, chunking it, generating its embedding representations and storing them in a Postgres WASM living in the browser.

Nothing leaves your browser, no API calls at all, other than to download the encoder-only model it needs to generate the learned representations of the chunked contents.
