Frequently Asked Questions

▶Can I extract numbers from handwritten open house sign-in sheets?

If you type or OCR the sign-in sheet into text, NumSwift will extract the numbers. Many agents photograph the sheet and use their phone's built-in text recognition (Live Text on iPhone, Google Lens on Android) to convert it to text first.

▶How fast can I follow up with leads after an open house?

You can paste your entire sign-in list into NumSwift and have all numbers extracted within seconds. Combined with one-tap WhatsApp messaging, you can realistically follow up with every lead within 15 minutes of your open house ending.

▶Does it work with international property buyers?

Yes. NumSwift recognizes phone formats from over 200 countries, which is particularly useful in markets with international buyers. Set the default country or let the tool detect country codes automatically from numbers that include a + prefix.

▶Can I send the same WhatsApp message to multiple leads?

NumSwift opens individual WhatsApp chats per number, so each message is a direct one-to-one conversation. This keeps your follow-ups personal rather than group-blast style, which leads to better engagement from potential buyers and sellers.
