Focus on what's in your control.
Discipline Isn’t Built on Motivation. It’s Built on Systems.
Thelwen is a Stoic focus system. Before a task gets your time, it asks one question: is this in your control? Then it helps you spend the day only on what is.
Free in your browser. No account, no card. The AI plans open to the waitlist first.
The question
Is this yours to decide?
The Stoics called it the dichotomy of control: some things are up to you, most are not. Thelwen asks before every task. Mine takes a place in your day. Not mine stays on the record and off your calendar.
| Task | Your answer | What happens |
|---|---|---|
| Finish the review draftGets a focus block | Mine | Gets a focus block09:00–11:00 |
| Whether the client repliesOn the record, off the calendar | Not mine | On the record, off the calendar |
| Draft the migration planGets a focus block | Mine | Gets a focus block11:30–13:00 |
| The budget decisionOn the record, off the calendar | Not mine | On the record, off the calendar |
| Twenty minutes outsideGets a place in the day | Mine | Gets a place in the day |
Everything else in the app follows from that answer. The focus timer only runs on work you called your own. The evening journal asks what was in your control today. Progress counts the hours you actually held.

Community
Built with the people who use it.
Thelwen is being built in the open, toward the largest community of people practising focus the Stoic way. It starts with three questions everyone on the waitlist answers.
What’s the problem you’re facing right now?
Procrastination · My phone pulls me away · Overthinking what I can’t control · Too many priorities · Burnout · No consistent routine · or your own words.
What would you want Thelwen to do for you?
An AI Stoic mentor to talk to · Analysis of where my focus goes · Sync across my devices · Blocking apps and sites · Challenges with other people · An iPhone app · or your own words.
What has actually helped you focus before?
Timers and focus blocks · Journaling · Exercise · Meditation · Reading the Stoics · Putting my phone away · Nothing has stuck yet · or your own words.
The answers are read, grouped and shared back with the community without names attached. The roadmap follows what people actually struggle with, and features are shaped in the open with the people who will use them.

Questions
What’s free, and what do the paid plans add?
Free is the core practice: the question before every task, focus sessions, the journal and progress, your daily streak and the Stoic Path, and Marcus Aurelius, Epictetus and Seneca, scripted from their writing. It runs in your browser with no account. Basic and Deluxe add a real AI Stoic mentor you can talk to, AI analysis of how you work, and sync across iOS, Android, Windows and the web.
What’s the difference between Basic and Deluxe?
Only how much you can talk to the mentor. Basic includes 50 mentor messages a day; Deluxe includes 100. Everything else is the same.
What happens to my data?
In the free app, what you write stays on your device and we never receive it. The paid plans will store your data on our servers so it can sync between your devices and be analysed for you. Every provider involved will be named in the Privacy Policy before they open. The waitlist keeps your name, email and answers.
Why is the price in my currency?
Everyone pays the same: US$15 a month for Basic or US$29.99 for Deluxe. Paid yearly, it is US$144 or US$288 a year. The page converts that into your currency at current exchange rates and rounds it up to a normal price. Choose your country next to the waitlist button to see yours.
When do the paid plans launch?
Dates go to the waitlist first. Joining costs nothing and doesn’t commit you to anything, and the free app is open now.
Focus on what's in your control.
The rest is noise. Start free today, and join the waitlist to help decide what Thelwen becomes.
