Send this to your assistant

Create a ClickRuntime automation: every 5 minutes, check my Projects board in Trello and post each new comment to #projects in Slack with the card name, the author and the comment.

Paste it into your assistant. It tells you what it will send or change before it runs live.

First time? Adding ClickRuntime to your assistant takes about two minutes.

Why use it

Why teams use this automation

Trello's email notifications for comments are inconsistent. They depend on each person's settings, get lumped with a dozen unrelated alerts, and are easy to turn off after the first noisy week. A project owner whose cards are being discussed by clients and teammates then misses a question on a card for two days, and the person who asked assumes they are being ignored.

Every five minutes, this looks at recent comment activity on your board, skips comments it has already reported and posts each new one to Slack with the card name, the author and the text of the comment. You see the conversation as it happens, without opening Trello.

It is handy for owners of shared boards where outsiders or other teams comment on cards. Owners no longer have to depend on their own notification settings or inbox filters to hear about a question.

What you get out of it

  • Questions get answered promptly

    A comment from a client reaches you within minutes, text included. You can respond from Slack quickly, so the person asking does not feel ignored while they wait for a reply.

  • The comment text is in the alert

    Seeing the actual words of the comment tells you whether it needs action now or can wait. You avoid opening Trello for every trivial thank you or emoji reaction. That saves a lot of idle clicking.

  • Independent of personal notification settings

    Whatever each teammate has configured in Trello, the board's comments still reach the channel. That gives owners a reliable feed instead of depending on settings nobody remembers choosing. The board stays covered for everyone.

  • Duplicate alerts are suppressed

    Each comment is reported once, no matter how many checks happen afterward. You are never flooded with copies of a comment that was already posted to the channel. Your Slack feed stays readable.

  • Evidence of who said what

    A running Slack record of comments, with authors, helps resolve later disagreements about what was requested. It is easier to search than scrolling through card activity logs. That helps settle later arguments.

How it works

What happens, step by step

  1. Every 5 minutes, ClickRuntime checks your Trello board for new comments.

  2. It skips comments it has already posted, so you never see the same one twice.

  3. Each new comment goes to your Slack channel with the commenter's name, the card name and the comment text.

Build your own

Need it to work differently?

This template is a starting point. Copy the prompt and change it, or describe a different automation from scratch, with your own conditions, more apps or an AI step. Your assistant writes it, tests it and runs it on ClickRuntime.
  • Your own rules

    Conditions, thresholds, filters and exceptions, written the way you'd explain them to a colleague.

  • Any number of apps

    One automation can read from one app and update several others. Over 248 apps are ready, and anything with an API works too.

  • AI where it helps

    Summaries, classification, extraction and drafts use ClickRuntime's built-in AI, with no extra key.

  • On a schedule or on each event

    Runs as often as every 5 minutes, or the moment an app sends an event, and keeps track of what it already handled.

Changes you can ask for

  • Act only on the items that match your own rules, and skip the rest
  • Add an AI step, for example to summarize, sort or draft a reply
  • Add another app, for example also send it to Slack
  • Combine it with other Trello steps into one automation

Under the hood

The code that runs this automation

This is the Python script that runs each time the automation starts. Your AI assistant writes it for you when you send the prompt, and you allow each step in your assistant. To change how the automation works, describe the change to your assistant and it updates the script for you. For every function it can use, see the script reference.

FAQ

Common questions

Does it report comments I wrote myself?
By default it reports all new comments, including your own, but it can skip comments by you so your feed only shows other people. Ask for that filter if the messages from your own replies feel redundant.
Are edited comments reported again?
No. An edit is not treated as a new comment, so the message about the original text stays as posted. If a comment changes meaning after being edited, you would need to look at the card itself.
Can I limit it to cards assigned to me?
Yes. You can restrict the alerts to cards where you are a member, or to certain lists or labels. That keeps the Slack feed tight on busy boards where many comments are about other people's cards.
What permissions does it need?
read. Nothing else in your accounts is used.
Does it need AI?
No. It runs without AI, so it doesn't use your plan's AI allowance.
How many runs does it use?
One run each time it checks. Checks that find nothing new and stop right away aren't counted.
Can I change how it works?
Yes. Describe the change to your AI assistant, for example a different schedule, channel or filter. It updates the automation, tests it and tells you what changed.
