Ask Fern Slack app
The Ask Fern Slack app allows customers to ask questions about your products directly in Slack channels and receive AI-generated answers from your documentation database.
Fern stores all questions and answers from Slack interactions for analytics purposes.
Setup
Install the Ask Fern app and add the bot to customer channels.
Install for your organization
To install Ask Fern in your organization’s Slack workspace, you must be a Slack admin. Follow these steps:
- In your Fern dashboard, click the Install to Slack button. You’ll be redirected to Slack to authorize the app
- Select the workspace where you want to add Ask Fern and click Allow

Enable for customer workspaces
To give customers access to the Ask Fern bot in their own Slack workspaces:
-
Generate a customer installation link by making a request to:
This returns a unique URL that your customers can use to install Ask Fern to their own Slack workspace.
-
Forward this link to your customer so they can install the Ask Fern app to their workspace.
-
Once the customer has installed the Ask Fern app, you must add the bot to your customer Slack channel to give it access.
Once added, customers will see that @Ask Fern was added to the channel
. They can start asking questions immediately.
Configuration
Customize the bot’s behavior to match your workflow needs.
Bot settings per channel
Use the /configure
slash command in any channel to adjust the settings:

Customize the bot name
You can rename the bot to match your brand (example: “YourCompanyName Support”):
- In Slack, go to Apps in the sidebar and click Ask Fern
- Click the About tab, then Configuration
- Scroll to Bot User section and click Edit
- Enter your preferred bot name and save changes

Now customers will see @YourCompanyName Support was added to the channel
instead of the default @Ask Fern
name.
Architecture
When a user asks Ask Fern a question in Slack, a webhook triggers Fern’s servers to search your documentation database and retrieve relevant context. Using that context, Ask Fern generates a response.
