# Start a new topic

Topics are a lightweight tool to keep conversations organized. You should
start a new topic whenever you're not replying to an existing message.

## Start a new topic

{start_tabs}

1. Click on a stream in the left sidebar.

1. Click **New topic** at the bottom of the app, or type <kbd>C</kbd>.

{end_tabs}

Don't worry about picking the perfect topic. The first 2-4 words that come
to mind are great.

Note that topics are not available for [private messages](/help/private-messages).
If you find yourself wanting topics in a PM, we recommend
[creating a private stream](/help/create-a-stream).
