Auto-triage your new support requests without lifting a finger. To turn on Plain’s AI features, go to Settings → Plain AI.

Auto-labelling

When a thread is created, Plain AI will add 1-2 labels automatically to a thread based on its content. If a thread was created with existing labels, no labels will be added. To best leverage Plain AI, make sure you’ve already set up Labels (Settings → Labels).

Thread titles

When enabled, this will automatically give each thread a short, descriptive title based on the content of the support request. This is particularly useful in Slack and other channels which, unlike email, do not have a subject line you can rely on.

Urgency detection

When enabled, Plain AI will automatically detect and flag threads that appear urgent – such as those mentioning downtime, blockers, or other high-impact issues. These threads are marked as Urgent, helping your team prioritize critical conversations without needing to rely on manual tagging or escalation.

This is especially useful when:

  • Customers don’t explicitly say a request is urgent, but their message implies it
  • You want to make sure incidents and outages are surfaced quickly
  • You’re coordinating across support and engineering during high-pressure moments

Once enabled, any new thread that AI classifies as urgent will appear in your Urgent view and be clearly labeled in the UI.

Thread summarization

As a thread grows over time, a summary of the thread will be added and kept up-to-date so you know what has happened without having to read the full timeline and every message. You can see the summary on the top right of any thread and in Slack notifications.

Similar threads

With this setting enabled, Plain AI will suggest similar threads in the thread details panel for the thread you’re currently viewing. This is useful to avoid duplicate work and to see if a similar issue has been resolved before.
