nottoofast turns your bad browsing habits into a typing game you can't rig.
- Add any website you want to think twice about — Reddit, Twitter, YouTube, whatever. Every time you navigate there, you're dropped into a typing test.
- Beat your personal WPM record and you're through. Fail and you stay put.
- The twist: your record updates every time you pass. The bar keeps rising, so you can never just coast on an easy score.
Features
- Block any site by hostname
- Live WPM counter while you type
- Stretched-exponential score decay — your required WPM slowly drops over time if you stay away, so a cold start isn't punishing
- Per-site score history with a WPM graph so you can see your progress
- Configurable grace period per site (brief visits don't trigger the test)
- Scheduled blocking windows — only active during hours you choose
- All data stored locally, nothing ever leaves your browser
