Currently, it is not possible to opt out of the Anthropic powered summaries.
This is on the roadmap; eventually you can opt for lower quality summaries to ensure that your data doesn’t get sent to Anthropic.
The Ask tl;dv functionality also uses Anthropic, however. In the future, users will eventually be able to opt out of any language-model-related implementations and completely isolate their data from third parties using our private cloud offering.
