The connection
How does Horizon actually get into Slack?
Horizon connects through Slack's official API. Your team approves which records Horizon can use and what it may prepare before the build starts.

What Horizon can prepare
Horizon shows your team channel messages, thread replies, reminders and supported workspace updates for staff review before posting.
How work can start
Slack can notify Horizon about selected channel and message activity, while scheduled checks build controlled digests and exception lists.
What we confirmed about the Slack connection
- The connection cannot silently read every private conversation in a workspace.
- Channel membership and the approved Slack user determine what Horizon can see.
- The strongest workflow turns discussion into a reviewed decision, owner and due date rather than merely summarising chat.

Day to day
Use Slack without jumping between systems.
Slack stays in place as the software your team already uses. Your team asks in Teams, Copilot, Claude or ChatGPT, and Horizon answers with only the approved records that request needs.
We connect one workflow first, prove it with your team on real review steps, then expand.

Common questions
Using Horizon with Slack, answered.
What could our team ask Horizon to do with Slack?
Find decisions, questions and commitments across the channels Horizon is allowed to use, then prepare the next action. Typical results include a decision and open-question digest, an unowned commitment list, and a Slack follow-up pack ready to approve.
Can our team use Slack from Microsoft Teams?
Yes, after the agreed access is approved. Your team asks Horizon in Teams, Horizon checks the approved Slack information and connected systems, then returns the answer or proposed action for review.
Can Horizon use Slack with Outlook, SharePoint or our other software?
Yes. We design one workflow around Slack and the other approved systems your team relies on, so the result can use the relevant information without staff opening each system separately.
Can Horizon prepare changes in Slack, not just answer questions?
Yes, where Slack supports the agreed action. Horizon prepares the change, shows it to the right person and applies it only under the permissions and review rules agreed for the workflow.
What would we start with in Slack?
We start with one useful, controlled request such as: @Horizon, summarise the decisions and unresolved questions from these project channels this week. The first version stays narrow enough to test with real staff and real review steps.
What access is needed before work starts?
A Slack owner or administrator installs the approved connection. Horizon can use only the channels and records available to that approved app or user.
Does Horizon replace Slack?
No. Slack remains the system your team uses. Horizon connects only the approved data and actions needed for the agreed workflow.
How does Horizon keep the Slack workflow safe?
We agree exactly which records, people and actions are in scope. We test one limited workflow with approved examples, keep important changes behind human review and expand only after the pilot is working properly.
The audit costs nothing
