HaloDiary

PayPal + AI Hackathon entry

Book it once. HaloDiary and your AI handle the rest.

The cleaner twice a week, the tutor after school, the dog walker at weekends. HaloDiary books them, checks with everyone the day before, holds each visit on PayPal and pays only after it happens, inside a budget you approve once. Your AI, or any agent you connect, can book and pay too, never past the limit you set.

One click, no email. The tour gives you a ready household in Barcelona; to swipe through matches yourself, choose Set up my own household. Payments run in the PayPal sandbox. Run a service business?

PayPal approval a month on HaloDiary, then it runs itself

How it works

  1. 1

    Tell the AI your week

    Write it in one sentence or tap the services you need. The assistant sets cadences and suggests a monthly budget.

  2. 2

    Swipe your best matches

    Every provider gets a match score from attendance, ratings, distance, price fit and how much they share. Swipe or browse a list.

  3. 3

    Sign once, approve once

    A service agreement binds both sides on notice, fees and credits. One PayPal approval covers the whole month.

  4. 4

    It runs itself

    Both sides get a check before each visit. PayPal holds the money when it's confirmed and pays the provider when it's done.

Agreements both sides sign

Notice for changes, late fees, credits when a provider cancels, notice to end. The scheduler enforces them and PayPal settles them.

Attendance you can see

Every provider shows the share of booked visits they turned up for, moved or cancelled, with the reasons they gave.

A real provider side

Providers build a profile with photo, team, website and socials, accept new clients, run their schedule and get paid out.

Why it matters

A huge, everyday market still run on chats and bank transfers

$122 billion

spent on home services in Europe in 2025, growing about 7.7% a year to 2035.

Paid only after the visit

Clients approve a month once; each visit is held on PayPal and captured after it happens. No prepaying, no chasing.

90% to the provider

Providers are paid out through PayPal straight after each visit. HaloDiary keeps 10%, and agreements protect both sides from late changes.

For judges

Try the whole loop in five minutes

Demo providers with varied ratings and attendance appear around wherever you are. They have no login, so HaloDiary's AI answers their chat in character.

  • PayPal Vault: one approval saves the payer for the month
  • PayPal Orders: hold on confirm, capture when done, void on skip
  • PayPal Payouts: 90% to the provider after each visit
  • Claude: assistant with one-tap approvals, routine parsing, matching welcome, provider chat
  1. 1

    Take the tour

    One click gives you a household with a cleaner and a dog walker already booked. A checklist walks you through the rest.

  2. 2

    Approve with PayPal

    Approve the month once with a PayPal sandbox account. No real money moves, and nothing is charged until a visit happens.

  3. 3

    Skip to tomorrow

    Confirm the day-before check: PayPal holds the price. Skip past the visit: it is charged and the cleaner is paid out.

  4. 4

    Let the AI book

    Ask the assistant for a babysitter. It books after your one-tap approval, inside your spending limit.

  5. 5
