An operating system for your life

When the plan breaks, Rewind picks it up.

Every productivity tool helps you make a plan. Rewind, built for people with ADHD, helps when the plan breaks. It detects disruptions, reschedules your day like an OS schedules processes, and drafts the busywork for you.

The Problem

Productivity tools are built for the plan. People with ADHD need help with what happens after it breaks.

Executive dysfunction

Planning isn't the problem

6.1 million adults in the U.S. are diagnosed with ADHD. Diagnosis isn't the hard part. With the executive dysfunction that comes with ADHD, starting can feel impossible even when you know exactly what you need to do. The problem is what happens when the plan breaks.

You know exactly what's next. Starting is the hard part.

Every tool, same flaw

They help you plan, then abandon you

Two members of our team live with ADHD. We've tried every productivity system: Notion databases, time-blocking in Google Calendar, even gamified to-do apps. They all fail the same way: they help you plan, then leave you on your own the moment something goes wrong.

The moment we target

The 15–30 minutes after a disruption

A meeting runs 15 minutes over. You space out for 10. By the time you've replanned, 45 minutes are gone, and your momentum with it. That window after the plan breaks, when you're silently stuck with no idea what to do next, is exactly where Rewind steps in.

With Rewind: a replanned day and a nudge on screen in under 3 seconds.

It's not a willpower problem. It's a working-memory problem.

When processes compete for limited CPU time and interrupts fire unexpectedly, an operating system doesn't panic. It doesn't delete processes when something changes; it reschedules them. Rewind applies the same model to your day.

LTSOS: plans allocation

Long-Term Scheduler

Plans your day. Scores tasks by deadline urgency (40%), priority (30%), peak-hour fit (15%) and duration (15%), then bin-packs them into your available hours, correcting for how much you usually underestimate.

MTSOS: handles swaps

Medium-Term Scheduler

Recovers from disruptions. When time is freed or lost, it swaps tasks between your active schedule and the backlog, and never schedules a task that's beyond your current energy.

STSOS: decides what runs now

Short-Term Scheduler

Picks what you do next. A four-level multilevel feedback queue (P0–P3) lets urgent tasks jump the line while respecting energy constraints.

Built from clinical research

We didn't start from a feature list. Each core workflow targets a specific ADHD challenge documented in clinical research.

Targets: Disruption paralysis

Disruption detection

The Context Sentinel watches your Google Calendar, Gmail and Slack. The moment reality diverges from your plan, the Disruption Detector rates it: minor (a meeting ran 5 min over), major (a meeting was cancelled) or critical (an urgent Slack from your manager).

Targets: Cognitive overload from replanning

Auto-rescheduling

You never replan by hand. The Scheduler Kernel rebalances your day across all three tiers and puts the single next thing to do in front of you.

Targets: Time blindness

Estimation correction

The Profiler Agent learns your actual peak hours (not when you think you're productive) and how much you underestimate tasks, then corrects every plan it makes. It gets smarter with every interaction.

Targets: Working memory limitations

Energy-aware scheduling

The Energy Monitor combines research-backed circadian patterns with how you actually complete tasks. The goal: never assign a task your brain can't handle right now.

Proactive: one-tap approvals

GhostWorker does the busywork

When being proactive can save you from a disruption, GhostWorker drafts the email, Slack reply or meeting reschedule for you. You approve it with one tap.
