I built a time tracker that measures how much AI saves you

#showdev #webdev #ai #productivity

I've been using Claude Code daily for months, and I kept asking myself: how much time is AI actually saving me?

Toggl and Clockify track hours, but they don't know the difference between me typing code and Claude generating it. WakaTime tracks IDE activity, but not AI processing time. None of them answer the real question: what's my AI productivity multiplier?

So I built Multick.

## What it does

Multick auto-tracks your Claude Code sessions using bash hooks. When you start a Claude Code session, a lightweight script sends events to the Multick API. No desktop app, no browser extension — just a bash hook and a web dashboard.

It tracks three things separately:

  • Your time: when you're actively working (prompting, reviewing, editing)
  • AI working time: when Claude is processing (between prompt submission and response)
  • Idle time: gaps longer than 5 minutes are automatically subtracted

Then it shows you the productivity multiplier:

You invested 4.2 hours. AI worked 1.8 hours. Effective output: 6.0 hours. Multiplier: 143%.

## Why this matters

If you freelance or work on a team, this metric is gold:

  • Freelancers: prove to clients that your AI workflow delivers more output per hour
  • Teams: measure AI ROI across the team, not just individual anecdotes
  • Managers: see which projects benefit most from AI assistance

## How setup works

  1. Sign in with Google or GitHub
  2. Create a project and set your local directory path
  3. Run bash hooks/install.sh — it configures Claude Code hooks automatically

That's it. Three minutes. Next time you open Claude Code in that project directory, Multick starts tracking.

## The stack

  • Next.js + TypeScript + Tailwind
  • Drizzle ORM + Neon Postgres
  • Auth.js (Google + GitHub OAuth)
  • Stripe for billing
  • Claude Code hooks (bash scripts)

## Pricing

  • Starter: $3/mo (3 projects, 7-day reports)
  • Pro: $9/mo (unlimited projects, CSV export, full history)
  • Team: $14/user/mo (team dashboards, per-member tracking)
  • All plans include a 7-day free trial
