Make useful process notes reusable

Preserve a well-written how-to message as a PDF so the next person can follow it without searching chat.

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 PDF

Tool to convert HTML to a PDF document. Use when you need to generate a PDF from raw HTML. Returns raw PDF bytes suitable for download or storage.

Why this helps

Repeatable instructions get rewritten because nobody can find the original post.

  • Keep reusable instructions in a portable format.
  • Make onboarding and handoffs less dependent on memory.
  • Cut down on repeated explanations.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Customjs to Notis once in the portal.
  • 2Create a new automation in the portal or ask Notis in plain language.
  • 3Tell Notis to create a concise PDF when a channel post contains a reusable process guide.
  • 4Choose the Slack channel message trigger and select a run-report channel.
  • 5Test with one process post and review whether the steps are easy to follow.

Questions about this workflow

Does this workflow discover processes across Slack?

No. It acts on new channel messages that match the instruction.

Can it include headings and steps?

Ask Notis to format the message as a guide while preserving its actual instructions.
