A woman has used WhatsApp for 9 years.
She opens the app 80+ times per day. She sends messages. She sends photos. She sends voice notes. She’s in 14 group chats. She considers herself an expert. She taught her parents how to use it.
Her brother a cybersecurity consultant who audits personal devices for executives looked at her WhatsApp settings for 2 minutes and told her something that made her lock her phone and open Settings before he finished the sentence.
“Anyone who has your phone number can see when you’re online. Anyone in a group chat with you can add you to another group without your permission. Your deleted messages are recoverable through notification history on any Android phone. Your View Once photos can be screenshotted on older app versions. Your chat backups to Google Drive or iCloud are not end-to-end encrypted by default meaning your ‘encrypted’ messages are stored as unencrypted backups in the cloud. You’ve never locked a single chat behind biometrics. You’ve never set a message to disappear. You’ve never silenced an unknown caller. And you’ve never turned on two-step verification meaning anyone who intercepts your SMS code can take over your account, read every message, and impersonate you to every person you know.”
He showed her 11 WhatsApp features that protect the privacy, security, and sanity of 2 billion users features most of those 2 billion have never configured.
Here’s every hidden WhatsApp feature most users have never touched 🧵

Ben used his iPhone for 8 years like a flip phone that takes good pictures.
Ben is 36. He rides his bike to work, and his phone does four things: calls, texts, maps and photos. Every other feature on it might as well be painted over.
Last month at a neighborhood cookout, he held up his phone to photograph a wedding invitation and then started typing the venue address into his Maps app, one letter at a time. Thumbs moving, tongue between his teeth.
His neighbor Carol was in the next lawn chair. Carol spent 20 years as a 911 dispatcher, and she has a trained instinct for watching people use their phones badly.
“What are you doing?” she asked.
“Copying the address.”
“By hand?”
“I don’t know another way.”
Carol set down her plate. “Ben. Tap the photo.”
“It’s already a photo.”
“Tap the text in the photo.”
He did. The address lit up. A small menu appeared with a Copy button.
Ben stared at it. “How long has it done that?”
“Since iOS 15. You’ve had it for years.” Carol shook her head. “I’m not surprised. In my 20 years on the headset, I talked to a lot of people on the worst night of their lives. You know what most of them had in common? A phone full of tools they’d never opened.”
“Like what?”
“Let’s start with that one. Then I’ll show you the one I care about most.”
By Christmas, he’d stopped retyping addresses from photos. He’d stopped digging through menus to turn on his flashlight. And he’d put the one thing in his phone that mattered most where a stranger could find it.
Here’s every iPhone feature Carol turned on for Ben 🧵
I AM QUITTING MY JOB TO GO FULL IN CLAUDE
Just asked him to:
"Analyze misspriced Polymarket markets opportunities for arbitrage and find wallets that are using it to copy"
Turned $2K into $12K in one night
Monitored ~1k+ wallets
I just realized that there are many arbitrage bots that I can't beat without code knowledge
But I can find them and copy
So Claude created a monitoring terminal and copytraded found wallets using TG copytrading bot
It's not a script and not even the bot, it's an AI agent that is improving with each found wallet
Fetching wallet behaviour, how it's trading, arbitrage, what's sized and timings
70% win rate, 7 wallets copytrading rn from ~500 monitored, bot never paused, never gambling, just math and profit

10. Google AI for Developers — Learn by building
🔗 https://t.co/7sQLIHNTws
Want to go beyond using AI and start building with it?
Explore Google's developer documentation, model capabilities, and API quickstarts.
Beginner project idea:
Build a simple tool that takes a topic and generates:
- 5 content ideas.
- 3 alternative hooks.
- A structured outline.
- A draft for human review.
Start with a small prototype before adding more features. API usage, quotas, and billing conditions vary.
BONUS: How to get more value from these tools
Don't try to master all 10 at once.
Build a simple workflow:
1. Research with Perplexity.
2. Organize your sources in NotebookLM.
3. Draft and refine ideas with Gemini.
4. Create visuals with Napkin AI.
5. Improve your audio with Adobe Podcast.
6. Publish your content and measure the results.
The real advantage isn't collecting AI tools.
It's combining the right tools into a repeatable workflow.
