Keepthis: a prefix for remembering links

Field notes

Keepthis uses a URL-prefix workflow: the user adds keepthis.link/ before a destination, after which the service says it stores the page and supplies a title plus three to six suggested tags. Its assistant integration is framed around MCP, with three named operations—search, recent, and keep—and examples that query saved items by subjects such as Japanese architecture or pricing. The homepage states that the service is free and requires no API keys, though the actual personal space is behind sign-in.
