Daily standup tool that auto-writes your update from your git commits

I spend five minutes every morning writing essentially the same standup update I could derive from my git log. I want a tool that connects to GitHub, looks at what I pushed yesterday, and drafts a plain-English standup — 'Yesterday I worked on X and Y, today I'm continuing with Z, no blockers.' I should be able to edit it before it posts to Slack. Bonus: if I have a GitHub issue linked in a commit message, it should surface the issue title instead of the raw commit message.
