Numbo
Your Easiest Way to Save WhatsApp Leads
I’ve been running WhatsApp-based lead campaigns for a while now. A lot of the people who message me aren’t saved in my contacts — which means every day I deal with a bunch of unknown numbers. At first, I was saving them manually. Then I started looking for tools to speed things up.
I tried Chrome extensions and Android apps that claimed to extract or save WhatsApp contacts in bulk. Some of them worked for a while, but honestly, the experience wasn’t great.
Here’s what I ran into:
Most extensions asked for access to everything in my browser
The apps wanted permissions to read my contacts, media, even messages
Tools would break every time WhatsApp updated
Some slowed down my browser or phone
I even got a warning from WhatsApp once
Many were filled with ads or required payments for basic features
That’s when I decided to build something simple and safe that just does the job without all the extra mess.
I made a tool called Numbo — it lets you extract and save unknown WhatsApp numbers by uploading a screenshot from WhatsApp Web. That’s it. No app to install, no login required, and no browser access needed.
It works on both desktop and mobile. It’s free, fast, and doesn’t touch your data.
If you’re running a small business, an agency, or just handling a lot of leads over WhatsApp, it might save you some time too.

Would love to hear what you think. Open to feedback or ideas for improving it.
Also happy to connect if you’re working on something similar. Thanks for reading.
Hey Indie Hackers 👋
I'm Ameer, and I just launched a small tool called Numbo to solve a frustrating problem I kept facing while running WhatsApp-based lead campaigns.
If you’ve ever run Facebook or Instagram ads where people DM you on WhatsApp — you probably know the struggle of saving unknown numbers one by one.
I tried browser extensions and mobile apps to fix this, but:
They asked for too many permissions
Some slowed down my browser
A few even triggered warnings from WhatsApp
Most were either filled with ads or just unreliable
So I built Numbo, a lightweight web tool where you can:
✅ Upload a screenshot from WhatsApp Web
✅ Extract all unknown numbers instantly
✅ No logins, no installations, 100% browser-based
✅ Works on mobile and desktop
✅ Completely free
I made it for myself first, and then a few agency friends tried it and loved it — so now I’m opening it up for others too.
Would love your feedback — feature ideas, bugs, UX suggestions — anything helps.

Hey webtoolsbyai
Just came across your product Numbo have to say absolutely loved the idea and execution. I'm a designer who’s worked on [Logo/UI/Landing page etc] For multiple brands.
Had a couple of small ideas that could instantly improve your [branding - i.e. Logo Design].
Would it be cool if I shared them with you?
No pressure at all — I just want to add some value. -

Hey, I think it's really cool, which is why my team did this: https://www.youtube.com/shorts/kzCZWlRWX2M - it's already getting some good views on Youtube Shorts. Seems like people like Numbo.
You've been featured on https://aisq.com/r/ this week and that's how more people found out about your launch. Share your Youtube Short and ask others to share it as well or comment on it.
Let's make this big!
Someone in my team like it a lot for the privacy part and suggest it needs to be featured, because not all founders think about sensitive details.
