Just say it
Brain-dump tomorrow out loud — in your language, your words. No forms, no fields.
Tomorrow starts tonight.

The evening ritual
Thirty seconds tonight.
A finished day tomorrow.
Words become the plan
AI reads your sentence and files each task under the right commitment. Your words stay yours.
You lose 5 times you die!
Show up and hearts refill. Ghost your plan and one shatters. Lose five times and it's game over.
How it works
Three little moves.
One growing story.
Say it at night. Keep it by day. Watch it become somewhere you've been.
Say tomorrow out loud
Each evening, open the Daybook and just talk. Chrona catches the tasks in your rambling, underlines them, and locks the page for tomorrow.
Keep a few little promises
Every task lives under a Contract — a promise like "the thesis" or "the client". Tick a box and the work counts somewhere. Up to ten stay active, so your head stays quiet without running out of room.
Contracts
Today's tasks
Watch your story grow
Every finished day raises an island in your weekly Chronicle. Not a productivity score — a place. Flip back any week and remember exactly what you built.
Try it now — no account
Dump your whole year.
Walk out with a plan.
Everything you want from the next 6–12 months — goals, wishes, deadlines. Say it messy. We'll hand it back as contracts.
Your year, unfiltered
Are you ready for it?
Your plan travels with you — sign up and these contracts are waiting, so you never type them twice.
4 weeks of Chronicle
After a month, your work stops disappearing.
Every week becomes a soft map of what landed: focused sessions, active contracts, tasks, deadlines, and the moments that changed your streak.

Five questions.
Five hearts.
Answer from how you actually work — every honest yes fills a heart.
Will you spend 30 seconds each evening saying tomorrow’s plan out loud (or typing it)?
Do you like working inside a few clear Contracts instead of one loose to-do list?
Will you use a focus timer when it’s tied to a real promise?
Do gentle stakes — hearts, deadlines, streaks — help you actually finish?
Would a visual weekly Chronicle make you review and improve your work?
50% off with the yearly plan
Your Annual Work Memo.
After the weekly Chronicles, we bind the year into a private book of Chronicle islands: readable, selectable, and calm enough to feel like a real page.
Yearly planners get the Chrona Book at half price — $14.50 instead of $29. We hand-review every year and use strong LLMs to produce it.
Loading your 2026 Annual Chronicle…
This isn't a mock-up. Every island in this book is a real week of building Chrona Day — the focus timer, the contracts, the Chronicles, the stats, right down to the page you're reading now.
The science behind it
Why saying it and keeping it
actually works.
The nightly Daybook and its weekly Chronicle aren’t productivity theatre — they’re built on how memory and motivation really work. Six findings, each with the paper attached, so you can read it for yourself.
- Zeigarnik effect
Open loops keep nagging.
Unfinished work stays half-awake in your mind, quietly draining you — until you say it into the Daybook and let the page hold it.
Masicampo & Baumeister, 2011 - Cognitive offloading
Your head is not storage.
Every detail you hold in mind is capacity stolen from thinking. Parking it somewhere trusted frees you for the real work.
Risko & Gilbert, 2016 - The progress principle
Visible wins keep you going.
The strongest workday motivator isn’t pressure or reward — it’s seeing real progress. Your Chronicle makes it impossible to miss.
Amabile & Kramer, HBR 2011 - The forgetting curve
Most of a week fades fast.
Without revisiting it, the detail of what you did decays within days. A weekly look-back is the re-exposure that keeps it.
Murre & Dros, PLOS ONE 2015 - Learning by reflection
Thinking back makes you better.
People who pause to reflect outperform those who just push on. Reading your own Chronicle is that pause, built into the week.
Di Stefano et al., 2014 - Retrieval practice
Recall, not re-reading.
Pulling a memory back out makes it stick far more than re-reading ever does. A weekly Chronicle is a gentle act of recall.
Roediger & Karpicke, 2006
Chrona Day exists to give your effort a memory — so the work you do this week is still working for you a year from now.
Tonight, take thirty seconds.
Tell tomorrow where to go.
Speak one plan into your Daybook, run one pomodoro, keep one heart. Four weeks from now you'll have the proof — a Chronicle of finished days.
