We got a question from an enterprise user of Storytell: "Is everything that is being summarized through StoryTell private to the user? Or is that data being made public?"
Here's the answer:
We do not publicly disclose your data. You can find our full Privacy Policy here.
How we process your source data to return a result to you:
We process your source data in a private computing cluster, which is end-to-end encrypted. We transform the raw source data using our proprietary AI algorithm, Mercury, into Story Tiles™ which are summaries of the original source data.
We then send these Story Tiles™ along with your user prompts to Large Language Model (LLM) services for further processing and to enable you to interact with the content via chat functionality.
For multi-media data: We will call a cloud-based "speech to text" API to turn the rich media into text for us to process, and we upload the raw video file to Visla, a processing partner, to cut the long-form content up into short-form snippets. (You can find Visla's privacy policy here).
Storytell does not store the raw rich-media source data that is provided to us.
A deeper dive into the terms mentioned above:
In our Chrome extension, the source data is typically the content from a web page and the prompt happens in the extension, like this:

In Slack the source data is a Slack message that can be of various types like a Zoom URL, an MP3/MP4, a text block etc, like this:

You can also learn more about what Story Tiles™ are here.
In addition, we are using Mozilla's readability library to parsing the HTML page to extract the text that will be sent to our backend for summarization (https://github.com/mozilla/readability). The behavior would be exactly same as Firefox's reader mode: https://support.mozilla.org/en-US/kb/firefox-reader-view-clutter-free-web-pages
We will not parse or read any password or sensitive information from the website.
For our Chrome Extension, you could control whether to send data to us by activating/deactivating our Extension.
You could toggle the activation state by clicking our icon.
Note that this is different with whether our pannel is open/closed. You could toggle the panel size by clicking the button. When the panel is minimized, the extension is still in activated state.
