AI HR Assistant:
Inside Slack.

01 // The Problem

HR as a
Help Desk.

The HR team spent a large part of every week answering the same questions in direct messages. How many days do I have left. Can I carry them over. What is the policy for working abroad. Time-off requests had a second problem. They reached managers without context, so conflicts with the team calendar, a short notice period or a missing balance were found after approval, or by HR cleaning up afterwards.

02 // What I Built

Answers From
the Handbook.

The assistant sits where people already ask: in Slack. It answers from the company's own HR documents and shows the policy section each answer comes from, so people can check it instead of trusting it. When the documents don't cover a question, it says so and hands the thread to a person in HR rather than inventing an answer.

03 // The Hard Part

The Bot Checks.
Humans Approve.

Time off is where an AI assistant can do real damage, so the split of responsibilities was the main design decision. The rules themselves, such as remaining balance, notice period, team overlap and blackout dates, run as ordinary code against the company's data, because they need to be right every time. The language model only reads the request and explains the result in plain words. The request then reaches the manager with the pre-check attached. The assistant never approves anything; the final decision stays with a person.

04 // Guardrails

Private by
Default.

HR data is personal, so access follows the person asking. An employee can ask about their own balance, not a colleague's, and the assistant only sees the documents it needs to answer. Conversations are logged so HR can review what the assistant said and improve the source documents where the answers were weak.
