What is WOOP?
Mental-contrasting journaling, inspired by Gabriele Oettingen's research. Journals stay private to you.
WOOP is a mental-contrasting framework developed by psychologist Gabriele Oettingen and her colleagues at NYU and the University of Hamburg. It turns a vague intention into four short, concrete steps you can write down in a couple of minutes.
The science
Decades of research (Oettingen et al., 2000–2020) show that vividly imagining a desired future and contrasting it with the internal obstacle in the way is what builds commitment to a wish worth pursuing — and releases one that isn't. WOOP pairs that with an if-then plan — Gollwitzer's implementation intentions — and the studies below find the pair outperforms either strategy on its own. Oettingen's lab has published more than fifty papers on mental contrasting since the 1990s; WOOP is the name she later gave the method so people could use it outside the lab.
What WOOP stands for
Wish
What do you want?
Name a meaningful, challenging but achievable goal. It can be big or small — what matters is that it matters to you.
Examples: “Exercise 3x this week”, “Finish the proposal”, “Call my mom”, “Learn to cook fish properly”.
Outcome
How will it feel?
Imagine the best result — how it feels, what changes. Let the picture be vivid. That picture is the fuel.
Try: “I feel energized and proud”, “The client is impressed”, “We laugh over dinner”, “I nail the sear on that salmon”.
Obstacle
What gets in the way?
Identify the internal barrier — habit, fear, doubt, impulse. Name it specifically. “I scroll instead of starting”. “I freeze when I don’t know the next step”.
Common patterns: perfectionism, avoidance, all-or-nothing thinking, “I’ll do it later”, fear of judgment.
Plan
Your if-then plan
Form an implementation intention: If [obstacle arises], then I will [specific action].
Examples:
- If I feel the urge to scroll, then I put my phone in the other room for 20 minutes.
- If I don’t know the next step, then I write the smallest possible first action on a sticky note.
- If I catch myself saying “I’ll do it later”, then I set a timer for 5 minutes and just start.
The plan lives in your journal. When the check-in arrives, you say how it went — I did it, Partially, I didn't, or Not yet — or snooze it until later.
A WOOP, as it looks in the app
Four short steps. Yours will read like you — this one belongs to a hypothetical early riser.
Run three mornings this week
Run three mornings this week.
I start the day clear-headed, and by Friday I'm proud I kept my word to myself.
When the alarm goes off, I tell myself one more snooze won't matter.
If I reach for the snooze button, then I sit up and put both feet on the floor before deciding anything.
How WOOP helps
woop.day is a private journal that walks you through the four steps, keeps your entries, and adds a light-touch coach that reflects on your patterns without judging them. If you lose signal while saving a WOOP entry, it's kept on your device and sent when you're back online. Key design choices:
- Sequential disclosure — one step at a time, no skipping.
- Cadence-aware — daily, weekly, monthly, yearly, or open-ended.
- Check-ins — gentle reminders at your chosen deadline; Followed through / Did not / Snooze actions.
- A coach — reads your journal and reflects it back, and walks you through the four steps when you want to build one.
- Privacy-first — entries you mark private never reach any model, and you can bring your own AI key if you'd rather.
- No likes, no social pressure. Just the method.
Three ways in
Type it. Any template, or plain free-writing.
Photograph it. Snap a page of your paper journal — it's transcribed into an entry you can correct.
Chat it out. Tell the coach what's on your mind and it drafts the entry with you — a WOOP, a gratitude list, a reflection. You review before anything saves.
The model behind the coach
By default the coach runs on Anthropic's Claude, on our house key — a key we hold — free, capped per day, nothing to set up.
Make it yours: bring your own key (You → Coach & AI → API keys) — no daily cap, your choice of provider and model, you pay only for what you use, and your journal talks to the model under your own account.
The app itself is free — no payments, no subscriptions.
