Tell HN: Gemini uses your email drafts (if you have "smart features" turned on)

Tell HN: Gemini uses your email drafts (if you have "smart features" turned on)

If you use Gmail, I think you all should know that if you turn your "smart features" on (a setting in gmail), the contents of your email drafts will make it into public-facing AI-generated content you generate. (I did have a chance to review it).

It was surprising behavior to me that's worth keeping in mind.

Detailed story:

I usually keep "Smart features" turned off in Gmail, however, I was using Google Gemini and file upload didn't work. I therefore shared from my Google drive, which required turning on "Smart features" in my gmail, so I did so.

Later, I was reading this announcement about a Google robot on Hacker News on my phone:

https://news.ycombinator.com/item?id=49111237

I started typing out a response on Hacker News but decided to make it a higher-quality comment so I saved my draft in gmail, and sent a second email to myself. I intended to continue working on these on my desktop.

I decided that I would like to include a survey people could fill out for Google to show what's important to them, and so once at my desktop I started a Google form. When I opened Google forms it now allowed me to use a prompt to generate my form, so I prompted it to make a survey of what's important to people in home robotics.

Instead of only using my prompt to make the Google form (which is what I would have expected) it also used my gmail draft and the email I had sent to myself.

This may be of concern, since you may be using Gemini to create public-facing documents, whereas you may consider your drafts or emails private, confidential, trade secrets, etc. For example, consider a company that discusses upcoming features it is discussing internally by email, and also, separately, generating AI content about its existing product, doing market surveys, etc.

It may be a surprise that the content AI generates effectively publishes the private emails and even drafts.

    Windows

    Each story opens in a window holding its article above its discussion; drag the bar between them to share the room differently. A window can be moved by its title bar, resized from any edge, snapped to a half or a corner by dragging it there, maximised, or minimised to the bar at the foot of the page. Use Window > New reader window to open an empty reader, or Story > Open in new reader window to open another reader for the current article. Docked readers keep their articles when you select another story from the sidebar. Minimized readers can be restored and reused for their site. A window's Next story link reads on down the list in the same window.

    A link in a comment or an article to another Hacker News or Lobsters thread opens that thread in a window too. A link to a single HN comment opens the comment above its replies.

    While a story's window is in front, the Story and Discussion menus in the menu bar hold its commands: pinning, Next story, sorting, collapsing every thread, jumping to the first new comment. Each window also remembers where you were in its article and discussion, so a reload, or Back to a story that Next took you past, finds your place again. Closing a window forgets it.

    The whole arrangement lives in the address, so a bookmark or a shared link brings it back, and Back undoes the last change. Moving between Hacker News, Lobsters, their lists, Pinned and Find changes only the list, and leaves the windows open.

    The list

    The pin at the start of a row keeps the story in Pinned, and the cross at its end hides it. Pinned can be narrowed by words in the title, site or author, by source, and to the stories you haven't opened yet, and ordered by when you pinned them, by points or by comments; the filters are part of the address, so a filtered view can be bookmarked. Scroll past the end of the list to load more. Domain filters, in the View menu, hide every story from a site.

    Collections are named lists of stories. Story > Add to collection files the story in front into one or more of them, and the Collections feed shows them all or one at a time; the menu that chooses collections also creates, renames, and deletes them. A note is your own text on a story. Choose Add note in a story's toolbar to write one; it saves as you type. Rows with a note carry the note mark, and the Notes feed lists every noted story and searches the text of your notes.

    Browsing view

    View > Windowed and View > Classic select the browsing view and save your default in this browser. Window view reuses a reader for each feed. Classic view opens stories and applets as pages. Open as a page is a one-off action that does not change your saved default. Use the Windowed selector to return an article to a window. Direct page links always open as pages.

    Applets

    The Applets menu in the menu bar holds three tools, each a window of its own. Replies to me takes your Hacker News user name and lists the replies to your last thirty comments and stories, checking again every three minutes while it is open, and marking what is new since you last marked them read. Look up a user opens a profile on Hacker News or Lobsters, with their submissions and recent comments, as a commenter's name in any discussion does; the bar at the top of a profile looks up someone else in the same window, and Back returns to the one before. Who is hiring? filters the posts of HN's monthly hiring threads by the words you type.

    They read only what the sites publish to everyone, so none of them asks for a login, and your user name stays in this browser anonymously and is included in retained applet state when signed in.

    Find

    Find takes any link and lists every time it was submitted to Hacker News and Lobsters, so you can read each discussion of it.

    About

    YAVCHN never sees your Hacker News or Lobsters login. The discussion is fetched from each site's public API; to vote or reply, follow the link above the discussion, or the arrow beside a comment, to the source's own site. Without a YAVCHN account, your data stays in this browser. When signed in, pins, collections, notes, blocked domains, and retained reading state are stored with your account and synchronized across devices. Hidden stories and layout stay in this browser. The privacy policy has the details.
