OpenAI has announced that ChatGPT will discontinue its services on WhatsApp starting January 15, 2026, due to changes in WhatsApp's policies. Users are encouraged to migrate to the ChatGPT app available on iOS, Android, Web, and Mac, which offers features like voice interaction, in-depth research, and file uploads. Users can link their phone numbers to their ChatGPT accounts via the "1-800-ChatGPT" contact on WhatsApp to sync historical chats. Post-January 15, WhatsApp will not support chat exports, so OpenAI advises users to complete the migration promptly, with guidance available in the Help Center.
