If the AI summary has been erased by mistake, make sure the automation will re-fill it. \n4. Reduce what is passed to the AI model to reduce the tokens consumption (e.g. to keep only the plain text version of the comments)"

About this workflow
This automation is for teams working in Notion. When you have a lot of back and forth in the comment section, it’s easy to lose track of what is going on in the conversation. This automation relies on AI to generate a summary of the comment section.
