It All Starts with My Phone Lying to Me
Sunday, 2:14 AM. I should be sleeping; instead, my phone’s screen time report rubs it in my face: 12 h 37 min of WhatsApp last week. I’m no exception — all of Brazil lives green bubbles. If AI was born to reduce friction, why the hell is it still stuck in a separate browser tab?
Realization goes more or less like this:
The vibe-coder generation already prototypes software talking to the keyboard.
Still, when they want to use what they’ve built, they have to paste a URL, remember logins, open Chrome, sometimes even figure out how to host something.
And I, who pride myself on building tools “for humans”, was accepting this as normal.
Shame — and motivation!
My Past Condemns Me (Or: Building WhatsApp Bots in 2018 Was Painful)
Quick flashback: in 2018, I built a bot that sent inventory forecasts to my logistics team. Four weeks just to handle Meta webhooks, certificates, and template approval. It worked, but it felt like installing a whole Windows 95 just to open Paint.
Jump to 2025. Today we have MCP (Model Context Protocol) — an elegant utility belt for our Agents — and a stack that exposes everything via API. The only piece missing was… guess what: WhatsApp without bureaucracy.
Sleepless Sprint, Cold Pizza, and the Right Question
“What if it was literally ‘next, next, finish’?”
That line came up in Tuesday's standup and kept echoing in my head. Next was:
One night hacking the business-account onboarding.
Shell script to automate the sandbox number.
Minimal UI: type a number → generate QR → done.
Seventy-two hours later I sent a “hi” to my own Agent via WhatsApp. It replied with events from my Google Calendar using MCP. Grouped up the team, screenshot on the call, collective laughter. We knew there was no going back.
How It Works Today (No Slides, Obviously)
Create or choose an Agent in the deco CMS dashboard.
Click on WhatsApp.
Enter your number.
Ready! Clicking on the number again or messaging our number:
You, chatting on WhatsApp, with the software you just invented. No need for anyone’s blessing.
Want to share? Just forward our number to a friend, client, or family group.
Why This Is Bigger Than It Looks
Zero on-boarding — the AI meets the user where they already are.
True inclusion — your aunt who thinks “prompt” is a dessert name can now automate a spreadsheet.
Instant feedback loop — testing, tweaking, and launching takes minutes, not sprints.
And of course, the big thing: the Agent stops being an alternative interface and becomes the main interface.
The Next Logical Step
We’re already playing around with Instagram DMs, Slack, and Microsoft Teams in the same plug-and-play model. My bet? Conversational interfaces will eat traditional front-ends at what they do best: solving small tasks in context.
Epilogue
If you’re already living this future with me, create your account at deco CMS (free), connect your number, and tell me what broke. I don’t promise funnels; I promise chronic curiosity.
See you on WhatsApp. 😉
