Who it’s for
For brains that were handed the wrong manual.
AuDHD. ADHD. Autistic. Or just permanently, quietly exhausted by systems that assume you can already start, prioritise and remember. If you could do all that reliably, you wouldn’t be reading this page.
Recognition first
You’ve done all this, haven’t you.
You’ve bought the planner. The nice one. It has eleven beautiful days in it and then a year of blank pages that make you feel worse every time you see the shelf.
You’ve built the perfect Notion workspace. It took a weekend, it was genuinely gorgeous, and you have not opened it since. Building the system was the dopamine. The system was never the point.
You’ve had a thought worth thousands of pounds or one important relationship, and lost it in the ninety seconds between the shower and the towel.
You’ve stared at a list of four things — none of them hard, all of them doable — and done none of them, for two hours, while feeling terrible about it the entire time.
You’ve finally got into something properly, for the first time all week, and had a timer tell you it was time for a break.
You’ve had a 61-day streak, missed one day for a completely reasonable human reason, watched it reset to zero, and never opened that app again.
You’ve opened an app to a wall of red “overdue” and closed it immediately, because the app had turned into one more person who was disappointed in you.
And you’ve concluded, somewhere along the way, that the problem must be you — because all these tools obviously work for everyone else.
It isn’t you. Those tools are well made. They’re just built on an assumption you can’t meet — that executive function is the thing you bring, and the app handles the storage. If executive function is the exact thing you’re short of, you’ve been handed a filing cabinet and told it’s a wheelchair ramp.
Specifically
Built around one AuDHD brain. Useful to a lot more.
Sarabellum was built by someone with an autistic and ADHD brain, for that brain, because nothing else fit. That’s not a marketing angle bolted on afterwards — it’s the reason every design decision went the way it did.
If you have ADHD
Capture costs nothing, so the thought survives. Today is short, so the list is faceable. The timer rewards the flow you waited all day for instead of severing it. And nothing is ever counting how many days you’ve been away.
If you’re autistic
The surface is calm and predictable, and it opens the same way every time. Nothing re-sorts itself behind your back — heat is visual only, order is manual and stays exactly where you put it. Routines are checklists, not challenges.
If you’re AuDHD
The one who needs structure and can’t maintain it. Novelty and routine, at war, daily. This whole app is that negotiation: deep structure underneath so the system holds, a simple surface on top so it never demands to be maintained.
No gatekeeping
You don’t need a diagnosis to be tired.
You don’t need a letter, an assessment, a waiting list or a label to use this. Plenty of people are undiagnosed, self-identified, on a three-year waiting list, or simply worn out by productivity guilt and looking for something that doesn’t moralise at them.
If the list at the top of this page felt like being read your own diary, you’re who this is for. That’s the whole entry requirement.
And to be very clear
Sarabellum is a task app. It is not a medical device, not a treatment, not therapy, and not a substitute for any of them. It doesn’t diagnose anything, it doesn’t claim to improve any condition, and it isn’t clinically validated.
It’s a well-shaped tool built by someone who needed one. Anybody promising more than that from a to-do list is selling you something.
The moat
Shame-free isn’t a feature. It’s the whole thesis.
Most apps motivate with a small, constant threat: the streak you’ll lose, the badge that turns red, the number that resets. It works on some people. On brains like ours it just adds shame to a pile that was already load-bearing — and shame is precisely what stops you opening the app, which is what stops the system working at all.
So we took the entire mechanic out. No streaks. No red. No guilt. Fall behind for a month and the app is exactly as pleased to see you as it was on day one.
Honesty
Who it isn’t for.
Teams
You can share a board with a few people by invite code, but there’s no assigning, no comments, no roles, no admin console. One brain steering, at most a few others along for the ride. Use Linear or Asana; they’re very good at real team workflow.
People who love their system
If Todoist works for you, genuinely: keep it. Switching costs are real and “it works” beats “it’s new”. We built this because nothing worked, not because nothing exists.
Anyone wanting to be managed
Sara will nudge you and pick your next task. She won’t report you, score you, or tell you you’ve been bad. If you want an app that’s disappointed in you, they’re all free.
Built for your operating system. Not theirs.
Free while it’s in beta. No card, no trial countdown, no catch.
