Why use WhatsChart?

• Maximum privacy

  WhatsChart works locally, which means NO data, including the chat you select, is ever sent to ANY server! WhatsChart does NOT collect any analytics or other data either.

• Completely open-source and free

  WhatsChart does not charge you anything! Anyone, including you, can read the source code anytime!

• Instant and customizable

  WhatsChart works instantly! One click and off you go! Additionally, WhatsChart is highly customizable and new customization options are still being added.

How to use?

1. Export your WhatsApp chats

1. Open the chat.
2. Tap More options > More > Export chat for Android. For iPhone Tap the contact's name or group subject > Export Chat.
3. Choose to export with media. If you decide to leave media out, you won't get statistics about media like pictures, videos etc.
4. File with name like chat.txt or WhatsApp chat with John.txt is the file you'll need. WhatsApp unfortunately doesn't follow a consistent pattern while naming the chat file. If a zip file was exported, unzip it to find the .txt chat file. Feel free to discard the exported media.
5. If you're still having trouble exporting your chats, refer to the following links from WhatsApp FAQ:
   • Android
   • iPhone

2.

• Hosted version:

  Prefer this way since you don't have to download/install anything. Head over to whatschart.bhumit.net

• Offline version:

  1. Clone the repo.
  2. Install the dependencies using npm install.
  3. Issue npm start command.
  4. Visit your localhost on specified port.
  5. Keep in mind that fonts won't work since they're pulled from Google fonts (unless you download them too).

3.

Go to generate page, select the exported chat file, configuration and click on Generate. You can then see/download the generated visualization. It is HIGHLY recommended that you use desktop or a device with wide screen to download the visualization. Please note that downloading is currently not supprted on Safari browser, please use Firefox or Chrome.
