Worklog is a Mac app that auto-logs everything you do in Claude Code, Codex and Cursor — then turns it into focus-time analytics and weekly reviews. The records pile up while you work.
$6.99 one-time purchase (¥980 in Japan) · macOS (Apple Silicon) · ~3 MB
Hooks into Claude Code, Codex and Cursor. Every session becomes a one-line log with title, duration and even the AI model used. The only thing you type by hand is meeting notes.
Idle time is excluded automatically. Run multiple AI sessions in parallel and overlapping periods are merged, so you see your true working hours.
Everything is stored as local plain-text files (JSONL). No cloud upload, no subscription — you can even grep it.
An auto-generated summary comment tells you what each day was about in one line. The time bar with hour marks shows when each project was active — including overlapping parallel sessions.
Hours by project and category, plus automatic breakdowns by AI model — Opus, Sonnet, GPT and more. The 6-month activity heatmap gives you a bird's-eye view of your work style.
For every project, Worklog auto-collects the latest artifacts, open tasks and next actions. And your accumulated logs become a one-click prompt — paste it into ChatGPT, Claude, Gemini or any AI to get time-allocation feedback and next week's focus. An analyzable asset that grows more valuable the more you work.
Light and dark themes, English and Japanese, and customizable category colors — pick from 14 presets or create your own with the color palette.
Worklog has no server. Every log lives in plain text (JSONL) on your Mac — read it, edit it, take it anywhere, anytime.
One file per day in ~/Documents/Worklog. Back up or sync however you like.
Zero analytics, zero tracking. Works entirely offline.
JSONL plus CSV export. Migrating elsewhere is a one-script job.
Setup takes 3 minutes. Integrations are one click.
