Google Discover automation

Hide publishers and topics from your Google Discover feed

Your Discover feed keeps showing one publisher and one topic you never read, and each fix means finding a card, tapping More and choosing an option, one card at a time.

Cotlet does it in your own Google Discover account with get_discover_feed, hide_publisher, mark_not_interested, list_hidden_items and unhide_item, called by your AI agent, an n8n workflow or a script.

Can Google Discover do this on its own?

Google has no API for these controls (checked 20 Oct 2026). They exist only on a card and in Manage interests. Google says the blocking feature may not be available in all languages and countries.

How you do it in Google Discover today

  1. On a card in the Google app or on google.com, signed in to your Google Account, tap More at the bottom right.
  2. Choose Not interested in the topic, or Don't show content from the source.
  3. To bring one back, open your profile, then Settings, then Interests, then Not interested, and tap Unhide next to the topic or source. In a browser the path is Settings, then Manage interests under Discover, then Not interested.
  4. You find a source only when its card shows up, so a publisher that appears twice a week takes weeks to clear.

How to hide publishers and topics from your Google Discover feed

Prompt

Read the top 30 cards of my Google Discover feed. Hide Example Daily News and mark every card about celebrity gossip as not interested. Then list what I have hidden.
  1. 01

    Read the feed

    Your agent calls get_discover_feed for the top cards and groups them by publisher and topic. A publisher or topic that fills many cards is the first candidate.

  2. 02

    Match your rule to cards

    The agent applies your prompt: this publisher, or every card whose topic is celebrity gossip. It lists what it will hide before acting, and skips a card whose topic is unclear instead of guessing.

  3. 03

    Hide the publisher

    hide_publisher presses Don't show content from the source. Hiding a publisher removes all its cards, so the agent runs it once per publisher, not once per card.

  4. 04

    Mark topics

    mark_not_interested presses Not interested in the topic on one matching card. One call per topic is enough, so the agent stops after the first card of each topic.

  5. 05

    Confirm with the hidden list

    list_hidden_items returns what the account now hides. The agent checks that every item it just added is in the list and tells you the call to undo each: unhide_item.

What you get back

Example data

Feed of my Google account (US), 30 cards read.
Hidden publisher: Example Daily News (7 cards)
Not interested: Celebrity gossip (5 cards)
Hidden in this account now: 2 publishers, 3 topics
Undo with unhide_item.

Other ways to ask

  • Hide every publisher that has more than 5 cards in my top 30.
  • List my hidden publishers and unhide the ones I added before September.
  • Follow the three publishers that cover home gardening best in my feed.

What Google Discover allows, and what to know first

  • Hide and Not interested need a signed-in Google Account, and they change only that account's feed.
  • Not interested in a topic and Don't show content from a source are separate options on the same card menu.
  • Hidden topics and sources are listed under Not interested, where each has an Unhide button.
  • Some of these features are not available in all languages and countries.

hide_publisher, mark_not_interested and unhide_item change only your own Google Discover data and reach no one else, so they run without asking first.
