Pencel

Appearance

Slack ​

Connect your Slack workspace and Pencel can read your channels, search past conversations and post messages for you, with your approval.

What Pencel can do with it ​

  • Catch you up. On Home, ask "Summarize this week's threads in #sales" or "What did I miss in #ops yesterday?"
  • Find a decision. "Find where we discussed the Henderson pricing and tell me what we agreed."
  • Post for you. "Post this week's bid summary to #bd." Pencel shows you the message first and posts only after you approve.
  • Look someone up. "Who handles procurement on the Slack workspace?"

What it can reach: the channels the connected account can see, their history, Slack search, your workspace's member list, and posting messages.

Connect it ​

  1. Go to Settings ▸ Connections ▸ Recommended.
  2. Find Slack and click Install.
  3. Your browser opens on Slack. Sign in, choose your workspace and allow access.
  4. Back in Pencel, the Slack card reads Installed.

If your workspace requires admin approval for new apps, ask your Slack admin to approve Pencel.

What needs your approval ​

Posting a message, or changing anything else in Slack, asks first. The approval card shows the channel and the exact message. You can approve it, Edit fields first, or Reject it.

For routine posts you trust, like a weekly summary to the same channel, Always Allow stops Pencel asking about that action.

Good to know ​

  • Pencel sees what the connected account sees. Channels it can't open are invisible to Pencel too.
  • Your messages go between your computer and Slack. Pencel's servers help only with the sign-in step. The AI model sees only what a task needs.
  • Rooms use only their own accounts. A room can read Slack only if it's set up to use this connection. See its settings under Advanced ▸ Tools & accounts.

Disconnect or change what it can do ​

Go to Settings ▸ Connections ▸ Installed and open the ⋮ menu on the Slack card.

  • Manage Tools: switch off anything you don't want Pencel to use, such as posting messages. Click Save changes.
  • Disconnect: stop Pencel using it for now.
  • Remove: delete the connection and its saved sign-in from Pencel.

To also withdraw access on Slack's side, remove Pencel from your workspace's installed apps in Slack.
