Free AI Task Prioritization

Stop staring at yourto-do list.

I'm David, 17, from Maine. I got tired of staring at my to-do list every morning with no idea where to start. So I built an AI that tells you exactly what to do first — and why. No other tool does this.

How ClarityOS
outthinks you
Most productivity tools just store your tasks. ClarityOS thinks about them — weighing urgency, impact, effort, energy, and opportunity cost — then breaks every task into actionable subtasks and tracks your progress in real time.
01
Contextual Intake
Your role, energy level, time, and goals shape every recommendation. What's right for a CEO at 9am differs entirely from a freelancer at 4pm with 90 minutes left.
Human-aware
02
Ranked + Subtasks
Every task is ranked by urgency, impact, and opportunity cost — then broken into 2-4 specific subtasks so you always know the exact next action, never just a vague goal.
Subtask engine
03
Track & Streak
Check off tasks and subtasks as you go. Watch your progress bar fill. Finish everything and trigger confetti. Build a daily streak to turn clarity into a habit.
Habit-forming
Pricing

The Story Behind ClarityOS
I built the AI I
wish I had.
"Every morning I'd open my laptop and stare at a list of 10 things with no idea where to start. I'd spend the first hour of my day just figuring out what to do — which means I was already behind before I'd started.
I tried every productivity app. They all had the same problem: they stored my tasks but none of them thought about them. None of them knew I had low energy on Tuesdays or that my deadline was tomorrow morning.
So I built ClarityOS. From my Chromebook. At 17. It's the tool I needed every single morning — and now it's yours too."

Why Not Just Use ChatGPT?
Good question. Here's the honest answer.
You could paste your to-do list into ChatGPT. We're not going to pretend you can't. But here's what ChatGPT doesn't know:
ChatGPT
✗Doesn't know your energy right now
✗Forgets everything after you close it
✗No streak — no habit formation
✗Can't track patterns across weeks
✗Generic answers for your specific life
ClarityOS
✓Knows your role, energy, and time available
✓Remembers your history and patterns (Pro)
✓Daily streak keeps you accountable
✓Weekly performance debrief sent to you
✓Built specifically for daily execution
ChatGPT is a blank slate. ClarityOS is a daily operating system.
The Streak That Changes Everything
Miss a day. It resets.
Duolingo built a billion-dollar company on streak psychology. ClarityOS uses the same mechanic — but for work. Every day you run a report your streak grows. The longer it gets, the more it hurts to lose. That's not manipulation — that's habit science.

FAQ
Common questions.
Everything you need to know before you start.
Your tasks are sent to the AI to generate your report and then stored securely in your account if you're logged in. We never sell your data, never share it with advertisers, and never use it to train AI without your consent. Full details in our Privacy Policy.
ClarityOS is powered by Anthropic's Claude — one of the most capable and safest AI models available. Pro users get access to deeper, more detailed reasoning per task.
Every time you hit "Analyze My Day" and get back a ranked priority list, that counts as one report. Free users get 3 per month — enough to feel the difference. Pro users get unlimited. Count resets the 1st of every month.
Yes — cancel anytime with one click through Stripe. No questions asked, no cancellation fees. You keep Pro access until the end of your billing period.
ClarityOS was built by David Tillotson, a 17-year-old from Kennebunk, Maine. He built it because every productivity app he tried just stored tasks — none of them actually thought about them. So he built one that does.
Yes — ClarityOS works on any device with a browser. The mobile experience is optimized with a simplified input flow. No app download required.
Every Sunday night, Pro users receive a personalized AI-generated email showing how many tasks they completed that week, what patterns emerged in their productivity, where their energy was highest, and what kept getting pushed. It makes ClarityOS feel alive between sessions and loads context for Monday morning.
Focus Mode is a Pro-only feature where you drop a single hard task and get a full AI execution plan — every subtask, recommended time blocks, potential blockers, and what to do if you get stuck. It's the "Chief of Staff" moment that no other tool at this price point offers.
The free plan gives you 3 reports per month — enough to feel the difference. Pro unlocks unlimited reports, pattern tracking across weeks, weekly AI debriefs, Focus Mode, and Carry-Forward Intelligence. At $9/month that's less than a coffee. And if it saves you even 30 minutes a day, the ROI is obvious.
