AI scheduling is active Change key
Welcome to
Phasethrive
A personalized wellness schedule built from your biology — cycle phase, chronotype, season, neurodivergent profile, and life structure.

Phasethrive helps you build a schedule that actually fits your life — not a template, but a plan tailored to the specific factors that shape your energy, focus, mood, and capacity on any given day.

Phasethrive draws on peer-reviewed research across several fields. Seasonal light changes affect brain chemistry, sleep, and mood in measurable ways across the year. Hormonal cycles and age — including perimenopause and menopause — shift cognitive capacity, emotional regulation, and recovery needs week to week. Neurological differences including ADHD and autism change the way energy is spent, recovered, and sustained. Chronotype, sleep, nutrition timing, movement, and social connection all interact to determine what a genuinely sustainable day looks like for a specific person.

Phasethrive was made by a neurodivergent woman, for neurodivergent women — but it can be used by anyone who wants to take a more complex and holistic approach to how they structure their time. If your life doesn't fit a one-size-fits-all schedule, Phasethrive was built for you.

All scheduling decisions are grounded in peer-reviewed research. View the research citations and evidence standards.

From the creator
A note from the Phasethrive creator on AI use

Most of us are not struggling because we aren't trying hard enough. We're struggling because the tools, the schedules, and the advice available to us were designed for a version of a person that most of us have never been.

This started from a simple place. I wanted a life that felt balanced, not optimized. I wanted to stop waking up having neglected my friendships, my body, my sleep, and the things that actually make me feel like a person, because something always seemed more urgent. I wanted a framework that understood that rest is not laziness, that a social life is not optional, that some weeks your nervous system needs gentleness and some weeks it can handle more, and that none of this is weakness.

I also wanted something that understood what it actually feels like to live in a body affected by hormones, seasons, and neurodivergence, and in the particular loneliness of a generation that stays in close contact with people it almost never sees in person. We text constantly and hug rarely. We follow the lives of people we love through small rectangles of light and call it connection, and on some level it is, but something still goes missing in translation. A schedule that doesn't account for the human need for real presence, real rest, and real joy is just a more elaborate way of burning out.

The research Phasethrive draws on covers all of it. How your cycle phase affects your cognitive and emotional capacity. How the light available to you in January versus June changes your brain chemistry in measurable ways. How masking your neurodivergence costs energy that has to come from somewhere. How hobbies, nature, solitude, and face-to-face connection are not rewards for finishing your work but essential inputs to a functioning human life. This science exists and it is well funded and peer reviewed, but it is scattered across disciplines nobody expects regular people to read. Phasethrive reads it for you and applies it to your specific life.

A few ways to use Phasethrive with a lighter footprint

Once you've generated a schedule that feels right, you don't need to start from scratch every time. Generate a weekly or monthly plan rather than a daily one once you understand your patterns. Save your output and use it as a reference for several weeks before regenerating. When you do come back, copy your previous notes into the additional context field so Phasethrive isn't rebuilding your profile from zero. The more you bring forward, the less processing is needed, and the smaller the footprint of each use.

On what this costs

Every schedule generation uses server energy and a small amount of water for data center cooling. The calculator below shows honest estimates based on published research. They are not alarming numbers, but they are real ones, and you should have them.

Use Phasethrive when it serves you. Use it thoughtfully. That's the whole point.

At 3 schedules/week, your annual AI energy use here is roughly equal to running your refrigerator for 5 hours, or charging your phone 158 times.
Estimates based on ~12 Wh per full schedule generation (Claude Opus, ~3,000 to 4,000 output tokens), using published inference benchmarks. Water estimate uses a standard data center WUE of 1.9 L/kWh. Anthropic does not publish exact per-request figures, so treat these as informed approximations, not audited data. Sources: energycosts.co.uk, Epoch AI, Our World in Data.

Step 1 of 7
About you
The basics that shape every layer of your schedule. All fields are optional — more detail means a more accurate result.
Chronotype is largely genetic and determines your optimal daily schedule structure
Used to calculate your current cycle phase
Perimenopause: use your recent average or best estimate
Step 2 of 7
Location & season
Where you live determines your seasonal light swing — the size of the gap between your shortest and longest days. This is one of the strongest environmental predictors of mood, energy, and sleep across the year.
Helps the AI calculate your exact sunrise/sunset times and seasonal light conditions
Step 3 of 7
Neurological & mental health
These inputs significantly reshape the schedule — recovery costs, attention patterns, sensory needs, and capacity are incorporated using 2024–2025 peer-reviewed research.
ADHD — inattentive ADHD — hyperactive ADHD — combined type Autism / ASD AuDHD (autism + ADHD) Anxiety disorder Depression PTSD / cPTSD Bipolar disorder OCD Seasonal Affective Disorder Highly sensitive person (HSP) Dyslexia / dyspraxia None / neurotypical
Task initiation difficulty Sensory overwhelm Gets deeply absorbed / loses track of time Social energy crashes Needs routine / dislikes change Motivation depends on interest
Stimulant ADHD (Adderall / Vyvanse / Ritalin) Non-stimulant ADHD (Strattera) SSRI antidepressant SNRI antidepressant Anti-anxiety medication HRT / estrogen therapy Thyroid medication Sleep medication None
Step 4 of 7
Physical health & energy
Chronic conditions and honest energy levels shape what a sustainable schedule actually looks like.
Chronic fatigue / ME-CFS Fibromyalgia Autoimmune condition Thyroid disorder Chronic pain Sleep disorder (insomnia / sleep apnea) Cardiovascular condition Diabetes / metabolic condition Digestive / IBS / IBD None of the above
1 = severely limited · 10 = consistently high. Be honest — this calibrates the entire schedule.
Step 5 of 7
Fixed schedule & life structure
Only add things here that genuinely cannot move — work shifts, school runs, medications, medical appointments, caregiving. If something is flexible or preferred rather than required, leave it out and let the AI place it optimally.
Fixed, non-negotiable blocks
These blocks will be locked into your schedule exactly as entered regardless of your cycle phase, energy level, or chronotype. Only add things that truly cannot be changed — the AI will work everything else around them.
Start time End time Description Recurrence
Work & purpose
Research sweet spot: 30–35 hrs/week (FWO-funded longitudinal study, 2024)
Household & caregiving
Step 6 of 7
Goals & output
Tell the system what you most want from this schedule and what kind of output you need.
Sleep / rest Movement / exercise Eating well / regular meals Time in nature Creative pursuits Social connection Time for myself / doing nothing My own health appointments Learning / personal growth Play / fun / spontaneity
I run out of time and it falls off the end of the day I intend to but can't make myself start I overcommit and then crash I get derailed and can't get back on track It feels selfish or hard to justify I don't have a structure so it just doesn't happen I'm too depleted by the time I get to it I say yes to things I should say no to I lose whole days to recovery after hard ones Everything feels equally urgent so nothing gets prioritized
Primary goals
Whole-life balance means all seven areas — sleep, health, movement, nature, social connection, creative interests, and work — are treated as equally important. Not just career vs. downtime. The schedule won't privilege productivity over the rest of your life.
Whole-life balance across all areas Prevent / recover from burnout Maximize work productivity Improve sleep quality Manage mood and emotions Build consistent exercise habit Improve social connection Manage hormonal / perimenopausal symptoms Improve nutrition and energy More time for hobbies and interests Reduce overwhelm and anxiety Better work-life balance Improve physical health Build sustainable routines Protect creative / special interest time

Profile summary
Evidence standard: All scheduling decisions are grounded in peer-reviewed research published 2019–2025, prioritising NIH, NIHR, Wellcome Trust, FWO Vlaanderen, and Karolinska-funded studies. Where evidence is limited (especially AuDHD + perimenopause intersectional research), this is stated explicitly in your output. Cycle syncing is presented as mechanistic extrapolation — not as a tested clinical intervention.
