Small, sharp tools
for thinking clearly.
Keirsdad builds offline-first productivity tools that work without accounts and stay out of your way. No onboarding, no sign-up wall. Just tools that do what they say.
The tools
Track daily, weekly, and monthly habits. Streaks, journal entries, and a calendar view — all stored on your device.
Weighted decision-making with a visual balance. Add arguments, assign weights, and see which side wins.
Memorise any text word-by-word. Paste what you need to learn, then practise until it sticks.
Read faster with RSVP. Paste any text and read word-by-word at your target speed with ORP highlighting.
Why Keirsdad
Offline-first
Every tool works without an internet connection. Your data lives on your device by default.
Your data on your device
What you write stays in your browser unless you turn on sync. We count how the tools are used, not what you put in them — the privacy policy says exactly what.
No accounts required
Open a tool and start using it. No sign-up wall, no email capture, no friction.
Optional sync
If you want your data on multiple devices, sync is available for a flat yearly fee. Otherwise, everything stays local.
How it works
- Pick a tool. Each one does one thing well.
- Use it immediately. No account, no setup. It works in your browser.
- Your data stays yours. Stored locally on your device. We never see it.
- Sync if you want. £20 a year. Sync everywhere. Cancel anytime.
