Tools for WhatsApp and customer engagement
Calculators and generators we built for our own customers, opened up for everyone. No signup, no email wall — every one of them runs in your browser.
WhatsApp essentials
Create a wa.me click-to-chat link with a prefilled message. Paste it in your bio, emails, ads or QR codes.
Turn your WhatsApp number into a print-ready QR code. High error correction, custom colour, PNG and SVG download.
Calculators
Work out your monthly WhatsApp Business API bill from Meta's per-message rates, in USD and INR.
Built for Indian D2C. Put a rupee figure on your COD RTO losses and see what a small reduction is worth.
Feedback & surveys
Why we built these
No email wall, no trial, no account. Use the tool, take the result, leave.
Nothing you type is sent to a server or stored. The maths happens on your device.
Rupee-first calculators and WhatsApp-first workflows, because that is where our customers are.
We build customer engagement software for WhatsApp. These tools solve the small problems around that work — generating a link, pricing a campaign, costing your returns. If they are useful, you will know where to find us when the bigger problem shows up.
When a tool stops being enough
A link needs an inbox behind it. A survey needs somewhere to send it. A QR code you have already printed needs to stay changeable. RateUp is the platform these tools point at — WhatsApp messaging, automation, feedback and loyalty in one place.
