Tools that give you
your day back.

Small daily friction adds up to hours we'll never get back — minutes lost to a JSON formatter, a forgotten cron syntax, another signup wall. This is 57 tools that give those minutes back to you, so the day ends a little earlier and the people who matter get a little more of you.

Why this exists

Most tools today want something from you — your email, your attention, a recurring subscription, a sales call. Then they layer on signup walls, cookie banners, upgrade prompts, and quiet telemetry. The minutes they take aren't visible day by day, but over a year they add up to days of your life.

These tools don't want any of that. They were built quietly, with care, so the small daily friction stops costing you hours — and so the day ends a little sooner, leaving more for the people you love and the life happening around your work.

For your work, and the life around it

The 58 tools cover the full working day, not just code. They're organized by what part of your day they help with:

🛠 For your code
JSON, regex, cron, encoders, diff, chmod, IP tools, color palettes, markdown — the things you keep googling.
⚡ For your focus
Kanban, daily planner, pomodoro, standup notes, meeting notes, sprint retro — small structures that add up to better days.
🎯 For your direction
OKRs, decision journal, goals tracker, ideas board — for the bigger picture you don't always have time for.
🌱 For your well-being
Sleep, gratitude, habits, energy, journal, fitness — because work isn't a life, and the people you care about deserve the better version of you.
📚 For your growth
Reading list, learning tracker, skill matrix, interview prep, bookmark manager — keep getting better, on your own terms.
💰 For your money
Budget planner, expense tracker, wealth dashboard — your numbers, your machine, no third party in the middle.

Yours to keep

Every tool is a single HTML file. Fork the repo and deploy to your own GitHub Pages in 30 seconds. Embed any one as an iframe in your team wiki. Customize the code freely — no build step, no framework, no lock-in. Nothing leaves your browser and nowhere else. Clear it and it's gone — that's a feature, not a bug.

For the developers among you: the Cron Builder exports on: schedule: blocks for GitHub Actions; Git Activity turns commit history into a heatmap; Project Health tracks deploys and uptime across your repo portfolio.

From the lab

Deck Studio — presentation decks from a spreadsheet, statement or report where every number traces back to its source cell. Figures are extracted by code, a local language model only writes the words around them, and delivery is blocked if any figure cannot be resolved. Runs on an open-weight model on a desktop Mac. Try it with the built-in sample statement.

If even one of these tools saves you ten minutes a week, that's eight hours a year back to your life. Spend them well.

Originally built as part of Lumen, a self-hosted personal AI system. Released free and open under MIT because care should be free too. Stars, forks, and PRs welcome on GitHub.
