Notis

Give every meeting a visual agenda

Turn the agenda your team already posted into a compact image that is easy to scan before the call.

Trigger

Channel Message Received

Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.

Action

Convert HTML to Image

Tool to convert HTML content into an image. Returns either a downloadable file or a JSON payload containing id and url, depending on the upstream API behavior.

Why this helps

Long agenda threads make it hard to remember what the meeting is meant to cover.

  • See the discussion topics at a glance.
  • Reduce last-minute searching through Slack threads.
  • Share one compact agenda with attendees.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Html to image to Notis once in the portal.
  • 2Create the automation in the portal or ask Notis conversationally.
  • 3Write one plain-language instruction asking Notis to turn agenda messages into a concise meeting card.
  • 4Select Channel Message Received and choose where Notis should report runs.
  • 5Test with one real agenda message.

Questions about this workflow

Does the automation create a calendar event?

No. It creates an image from the Slack agenda message.

How can I keep the card concise?

Ask Notis in the instruction to include only the meeting title, time if present, and key agenda points.
