I built a Slack bot that silently tracks commitments — here's how it works

Every team I've been on has the same problem: someone makes a promise in Slack, it gets buried in a thread, and nobody follows up.

"I'll get that PR reviewed by EOD" — forgotten.
"Let me send that doc over tomorrow" — gone.
"I'll sync with the client on Friday" — missed.

So I built Commitment Crawler — a Slack bot that watches your channels, detects commitments automatically using AI, and privately nudges people before deadlines slip.

How it works

1. Install the bot into your Slack workspace
2. It silently monitors channels it's been added to
3. GPT-4o detects when someone commits to something ("I'll have X done by Y")
4. It privately DMs the person a reminder before the deadline
5. Users manage their tracked commitments via /commitments

Why private nudges?

Public reminders create embarrassment. Nobody wants a bot to call them out in front of the team. Private DMs mean people actually appreciate the nudge instead of resenting it.

Tech stack

• Slack Bolt SDK (Node.js) for the bot framework
• OpenAI GPT-4o for natural language commitment detection
• Serverless deployment — no infrastructure to manage
