WhatsApp Missed Follow-Up Finder

Check exported customer chats for unanswered questions and customer messages that may need a follow-up.

Your chats never leave your device

Each file is read by your own browser, on this page. Nothing is uploaded, nothing is saved, and no names or messages are sent to us or to any analytics service. Close the page and it is gone.

How it works

  1. Export up to 20 one-to-one customer chats from WhatsApp and choose them all here.
  2. Pick which participant is your business in each chat, then confirm the timezone, the export date and the reply target (4 hours by default).
  3. Read the questions that got no reply within the target and the chats where the customer wrote last, then download the summary or the excerpts you tick.

Example

Input

27/10/2026, 09:00 - Maya: Hi, do you have a table for four tonight?

27/10/2026, 09:20 - Cafe Lev: Yes, 20:00 works.

27/10/2026, 09:30 - Maya: Great, thanks!

27/10/2026, 09:31 - Maya: Can I bring my dog?

27/10/2026, 11:30 - Cafe Lev: Sorry, only on the terrace.

27/10/2026, 12:00 - Maya: Is the terrace heated?

Business: Cafe Lev. Exported on 27/10/2026 18:00, reply target 4 hours.

Result

  • One candidate: "Is the terrace heated?" at 12:00, waiting 6 hours at the export.
  • The two earlier questions got replies within 4 hours, so they are not listed.

Limits

  • These are candidates for a follow-up, not proven lost sales: a customer may have been answered by phone, in person or in another chat.
  • Exports carry no read receipts and no reliable agent identity, so the tool cannot tell who read a message or which teammate replied.
  • Deleted messages and anything sent after the export are unknown to the tool.
  • A question is a customer message ending in a question mark. Questions asked without one are not found.
  • Waits are elapsed clock time, nights and weekends included, not Spun's live first-reply target.
  • The results describe the chats you uploaded only, not your whole WhatsApp account.

What counts as a follow-up candidate

An unanswered question is a customer message ending in a question mark that the business did not answer within the reply target. If the business replied later, the wait shows how much later.

A chat where the customer wrote last is listed when the last message is the customer's and it is older than the target at the export date. Anything younger than the target is counted as too recent to judge.

How to export a WhatsApp chat

On iPhone

  1. Open the chat or group in WhatsApp.
  2. Tap the contact or group name at the top.
  3. Scroll down and tap Export Chat, then Without Media (faster) or Attach Media.
  4. Save the .zip to Files, then choose it on this page.

On Android

  1. Open the chat or group in WhatsApp.
  2. Tap the three dots at the top, then More, then Export chat.
  3. Choose Without media (faster) or Include media.
  4. Save the file to your phone or send it to yourself, then choose it on this page.

Export each customer chat separately and choose all the files at once. WhatsApp exports at most the latest 40,000 messages without media, or 10,000 with media.

Frequently asked questions

Is my chat uploaded anywhere?

No. The files are read by your browser on this page. Nothing is uploaded or saved, and no names or messages reach Spun or any analytics service.

How many chats can I check at once?

Up to 20 one-to-one chats, .txt or .zip, with up to 50 MB of chat text in total. The same chat added twice is counted once.

Why was my group chat rejected?

The finder looks at one business and one customer. In a group, a message may be answered by anyone, so the results would not mean the same thing.

Does every candidate mean a lost customer?

No. A candidate is a chat worth a look. The customer may have been answered in another way, or may not need anything more.

Why do I need to confirm the export date?

WhatsApp exports do not record when they were made. The wait of the last messages is measured up to the date you confirm.

Can I share the results with my team?

Yes. Download the summary, which holds counts and times only, or the excerpts of the items you tick. Both files are made on your device.
