Your money, one text away: meet Moola on WhatsApp

We built Moola to make personal finance feel less like homework and more like talking to a friend who happens to be brilliant with money. Today we're taking that idea somewhere it's always belonged — the app you already check dozens of times a day. You can now text Moola on WhatsApp.

No new app to download. No password to remember. No dashboard to open. Just open WhatsApp, type a question about your finances, and get a real, personalised answer back in seconds.

What this actually feels like

Picture the moments money decisions actually happen. You're standing in a dealership wondering if you can stretch to the nicer car. You're at dinner and a friend mentions overpaying their mortgage. You're lying awake at 11pm doing the "am I going to be okay?" maths in your head.

Those moments don't wait for you to get to a laptop. Now they don't have to.

• "Can I afford a £30k car?"

• "How am I doing this month?"

• "What happens to my pension if I drop to four days a week?"

  
  

Ask Moola the way you'd text anyone else, and it answers using your actual financial picture — your income, your goals, your numbers — not generic advice off the internet.

Why we think this matters

It meets you where you already are. WhatsApp is the most-opened app on most people's phones. By bringing Moola into it, we remove the single biggest barrier to good financial habits: friction. The best money tool is the one you'll actually use, and you're already in WhatsApp ten times a day.

It turns guidance into a habit, not a chore. Checking a finance dashboard is something you decide to do. Sending a text is something you just do. That shift — from deliberate session to casual conversation — is how good habits actually form. A quick "how am I doing?" on the bus home is worth more than a detailed review you keep meaning to schedule.

It's genuinely personal. This isn't a chatbot reciting tips. Moola on WhatsApp draws on the same financial model that powers your dashboard — the same understanding of your income, spending, goals and circumstances. The answer you get is about your money, phrased for a human, delivered to your pocket.

It's fast. We rebuilt the conversation engine so WhatsApp replies come back quickly and read naturally — short, clear, and to the point, the way a good text should. No essays, no jargon walls. Just the answer you asked for.

A note on trust and safety

We take the "your money" part seriously, so a few deliberate design choices:

• You opt in, explicitly. The channel is off until you connect it from the web. You link and verify your own phone number with a one-time code — so only you can connect your account, and only a phone you control receives your information.

• Guidance, not advice. Moola gives general financial guidance to help you think clearly. It won't move your money or make decisions for you — and it'll tell you plainly that it's guidance, not regulated financial advice.

• You're always in control. Reply STOP at any time to opt out. Your consent is yours to give and yours to take back.

  
  

How we built it (the mid-level technical bit)

For the curious — and the builders — here's roughly how it works under the hood.

WhatsApp Business via Twilio. Rather than wiring directly into Meta's WhatsApp Business Platform, we run the channel through Twilio, which sits as a managed layer between Moola and WhatsApp. Twilio handles the messaging plumbing — delivery, the Business sender identity, and Meta's approval process — so we can focus on the conversation itself. Messages from our verified business number (Moola, +44 7700 145005) flow both ways through Twilio's APIs.

Linking your number. When you connect WhatsApp from the web, we send a one-time verification code to your phone. WhatsApp is strict about businesses messaging people out of the blue, so that first message uses a pre-approved message template — a fixed format Meta has reviewed and signed off in advance (in our case, an authentication template that simply delivers your code). Once you reply, a 24-hour conversation window opens in which Moola can talk to you freely. The same applies to the friendly "You're connected 👋" welcome message — it's a separate approved template, because Moola is starting that conversation rather than replying to one.

The inbound flow. Every message you send hits a secure webhook (/api/whatsapp/webhook). We verify the request genuinely came from Twilio (signature validation, so nobody can spoof messages on your behalf), figure out which account the number belongs to, and hand the question to the same AI engine that powers Moola on the web. That was the key architectural decision: WhatsApp isn't a bolt-on with its own brain. It shares one core — the same profile data, the same prompt-building, the same model — so the answer you get over text is consistent with what you'd get on your dashboard. We just tuned the output to be shorter and snappier for a chat window.

Built for reliability. Hardening the messaging plumbing is most of the real work — getting templates approved, validating webhook signatures, keeping configuration clean (a stray character in a setting once silently broke message sending — the kind of thing only production teaches you). The payoff is a channel that just works, quietly, every time you text.

Try it

If you're a Moola user, head to your settings or the dashboard and look for the option to connect WhatsApp. Link your number, say hi, and ask Moola the money question that's actually on your mind.

The smartest financial companion you have is now one text away.
