DanswerBot Introduction

Danswer will connect to your Slack and listen for messages to answer.

You can easily configure rules for what channels Danswer should respond in, what knowledge sets should back each configured channel, and set filters to respond or not respond to different types of messages.

When Danswer identifies valid questions, it will respond in the message thread with:

  • An LLM generated answer
  • Quotes of the most relevant excerpts
  • Sources with highlighted keywords


Danswer also provides a configuration page so you can create custom settings for each slack channel (or you can just use the default settings for all your channels).


Since we are using Web Sockets, Danswer is able to initiate the connection. This means that this is able to work even if you are running Danswer inside a firewall protected VPC.

Setting up


Note: You must be an admin of the Slack workspace to set up the Slack bot.

  1. Navigate and sign in to https://api.slack.com/apps.
  2. Create a new Slack app:
    • Click the Create New App button in the top right.
    • Select From an app manifest option.
    • Select the relevant workspace from the dropdown and click Next.


  1. Copy the following manifest into the text box
  name: DanswerBot
  description: I help answer questions!
    home_tab_enabled: false
    messages_tab_enabled: true
    messages_tab_read_only_enabled: false
    display_name: DanswerBot
    always_online: true
    - command: /danswer
      description: Get back a private answer!
      usage_hint: Put your question here!
      should_escape: false
      - app_mentions:read
      - channels:history
      - channels:join
      - channels:read
      - chat:write
      - commands
      - groups:history
      - groups:read

  1. Click the Create button.
  2. Generate an App-level Token, following the guide here. Add the connections:write scope to the app-level token and click Generate. Copy this somewhere safe for now, as you will need this later to initiate the Web Socket-based connection to Slack.
  3. In the app page, navigate to the OAuth & Permissions tab under the Features header.
  4. Under OAuth Tokens for Your Workspace, select Install to Workspace and Allow the app. DanswerBotInstall
  5. Copy the Bot User OAuth Token, this will be needed later to enable us to respond to messages as DanswerBot.

Setting Danswer to use it

Start by finding the admin page in the top right of the Danswer web UI. DanswerAdminButton

On the left hand menu of the admin page, navigate to the bottom to Bots.

Provide your Slack Tokens and Danswer will start to respond to your slack channels after a short startup delay. SlackBotTokens

There are also a set of less often used / more advanced configuration options available via environment variables that can set things like how many “Reference Documents” to show per answer, etc. Refer to the available configs here
